<title>Introduction</title>
<para>
This document describes the interfaces available for device drivers that
drive s390 based channel attached devices. This includes interfaces for
interaction with the hardware and interfaces for interacting with the
common driver core. Those interfaces are provided by the s390 common I/O
layer.
</para>
<para>
The document assumes a familarity with the technical terms associated
with the s390 channel I/O architecture. For a description of this
architecture, please refer to the "z/Architecture: Principles of
Operation", IBM publication no. SA22-7832.
</para>
<para>
While most I/O devices on a s390 system are typically driven through the
channel I/O mechanism described here, there are various other methods
(like the diag interface). These are out of the scope of this document.

<title>The ccw bus</title>
<para>
The ccw bus typically contains the majority of devices available to
a s390 system. Named after the channel command word (ccw), the basic
command structure used to address its devices, the ccw bus contains
so-called channel attached devices. They are addressed via subchannels,
visible on the css bus. A device driver, however, will never interact
with the subchannel directly, but only via the device on the ccw bus,
the ccw device.

ccw device structure. Device drivers must not bypass those functions
or strange side effects may happen.

@@ -241,68 +241,7 @@ address space of the MSI-X table/MSI-X PBA. Otherwise, the PCI subsystem
will fail enabling MSI-X on its hardware device when it calls the function
pci_enable_msix().
5.3.2 Handling MSI-X allocation
Determining the number of MSI-X vectors allocated to a function is
dependent on the number of MSI capable devices and MSI-X capable
devices populated in the system. The policy of allocating MSI-X
vectors to a function is defined as the following:
#of MSI-X vectors allocated to a function = (x - y)/z where
x = The number of available PCI vector resources by the time
the device driver calls pci_enable_msix(). The PCI vector
resources is the sum of the number of unassigned vectors
(new) and the number of released vectors when any MSI/MSI-X
device driver switches its hardware device back to a legacy
mode or is hot-removed. The number of unassigned vectors
may exclude some vectors reserved, as defined in parameter
NR_HP_RESERVED_VECTORS, for the case where the system is
capable of supporting hot-add/hot-remove operations. Users
may change the value defined in NR_HR_RESERVED_VECTORS to
meet their specific needs.
y = The number of MSI capable devices populated in the system.
This policy ensures that each MSI capable device has its
vector reserved to avoid the case where some MSI-X capable
drivers may attempt to claim all available vector resources.
z = The number of MSI-X capable devices populated in the system.
This policy ensures that maximum (x - y) is distributed
evenly among MSI-X capable devices.
Note that the PCI subsystem scans y and z during a bus enumeration.
When the PCI subsystem completes configuring MSI/MSI-X capability
structure of a device as requested by its device driver, y/z is
decremented accordingly.
5.3.3 Handling MSI-X shortages
For the case where fewer MSI-X vectors are allocated to a function
than requested, the function pci_enable_msix() will return the
maximum number of MSI-X vectors available to the caller. A device
driver may re-send its request with fewer or equal vectors indicated
in the return. For example, if a device driver requests 5 vectors, but
the number of available vectors is 3 vectors, a value of 3 will be
returned as a result of pci_enable_msix() call. A function could be
designed for its driver to use only 3 MSI-X table entries as
different combinations as ABC--, A-B-C, A--CB, etc. Note that this
patch does not support multiple entries with the same vector. Such
attempt by a device driver to use 5 MSI-X table entries with 3 vectors
as ABBCC, AABCC, BCCBA, etc will result as a failure by the function
pci_enable_msix(). Below are the reasons why supporting multiple
entries with the same vector is an undesirable solution.
- The PCI subsystem cannot determine the entry that
generated the message to mask/unmask MSI while handling
software driver ISR. Attempting to walk through all MSI-X
table entries (2048 max) to mask/unmask any match vector
is an undesirable solution.
- Walking through all MSI-X table entries (2048 max) to handle
SMP affinity of any match vector is an undesirable solution.

Introduction to NAPI
====================
NAPI is a proven (www.cyberus.ca/~hadi/usenix-paper.tgz) technique
to improve network performance on Linux. For more details please
read that paper.
NAPI provides a "inherent mitigation" which is bound by system capacity
as can be seen from the following data collected by Robert on Gigabit
ethernet (e1000):
Psize Ipps Tput Rxint Txint Done Ndone
---------------------------------------------------------------

1440 85193 1000003 946576 19505 946569 0
Legend:
"Ipps" stands for input packets per second.
"Tput" == packets out of total 1M that made it out.
"txint" == transmit completion interrupts seen
"Done" == The number of times that the poll() managed to pull all
packets out of the rx ring. Note from this that the lower the
load the more we could clean up the rxring
"Ndone" == is the converse of "Done". Note again, that the higher
the load the more times we couldn't clean up the rxring.
Observe that:
when the NIC receives 890Kpackets/sec only 17 rx interrupts are generated.
The system cant handle the processing at 1 interrupt/packet at that load level.
At lower rates on the other hand, rx interrupts go up and therefore the
interrupt/packet ratio goes up (as observable from that table). So there is
possibility that under low enough input, you get one poll call for each
input packet caused by a single interrupt each time. And if the system
cant handle interrupt per packet ratio of 1, then it will just have to
chug along ....
0) Prerequisites:
==================
A driver MAY continue using the old 2.4 technique for interfacing
to the network stack and not benefit from the NAPI changes.
NAPI additions to the kernel do not break backward compatibility.
NAPI, however, requires the following features to be available:
A) DMA ring or enough RAM to store packets in software devices.
B) Ability to turn off interrupts or maybe events that send packets up
the stack.
NAPI processes packet events in what is known as dev->poll() method.
Typically, only packet receive events are processed in dev->poll().
The rest of the events MAY be processed by the regular interrupt handler
to reduce processing latency (justified also because there are not that
many of them).
Note, however, NAPI does not enforce that dev->poll() only processes
receive events.
Tests with the tulip driver indicated slightly increased latency if
all of the interrupt handler is moved to dev->poll(). Also MII handling
gets a little trickier.
The example used in this document is to move the receive processing only
to dev->poll(); this is shown with the patch for the tulip driver.
For an example of code that moves all the interrupt driver to
dev->poll() look at the ported e1000 code.
There are caveats that might force you to go with moving everything to
dev->poll(). Different NICs work differently depending on their status/event
acknowledgement setup.
There are two types of event register ACK mechanisms.
I) what is known as Clear-on-read (COR).
when you read the status/event register, it clears everything!
The natsemi and sunbmac NICs are known to do this.
In this case your only choice is to move all to dev->poll()
II) Clear-on-write (COW)
i) you clear the status by writing a 1 in the bit-location you want.
These are the majority of the NICs and work the best with NAPI.
Put only receive events in dev->poll(); leave the rest in
the old interrupt handler.
ii) whatever you write in the status register clears every thing ;->
Cant seem to find any supported by Linux which do this. If
someone knows such a chip email us please.
Move all to dev->poll()
C) Ability to detect new work correctly.
NAPI works by shutting down event interrupts when there's work and
turning them on when there's none.
New packets might show up in the small window while interrupts were being
re-enabled (refer to appendix 2). A packet might sneak in during the period
we are enabling interrupts. We only get to know about such a packet when the
next new packet arrives and generates an interrupt.
Essentially, there is a small window of opportunity for a race condition
which for clarity we'll refer to as the "rotting packet".
This is a very important topic and appendix 2 is dedicated for more
discussion.
Locking rules and environmental guarantees
==========================================
-Guarantee: Only one CPU at any time can call dev->poll(); this is because
only one CPU can pick the initial interrupt and hence the initial
netif_rx_schedule(dev);
- The core layer invokes devices to send packets in a round robin format.
This implies receive is totally lockless because of the guarantee that only
one CPU is executing it.
- contention can only be the result of some other CPU accessing the rx
ring. This happens only in close() and suspend() (when these methods
try to clean the rx ring);
****guarantee: driver authors need not worry about this; synchronization
is taken care for them by the top net layer.
-local interrupts are enabled (if you dont move all to dev->poll()). For
example link/MII and txcomplete continue functioning just same old way.
This improves the latency of processing these events. It is also assumed that
the receive interrupt is the largest cause of noise. Note this might not
always be true.
[according to Manfred Spraul, the winbond insists on sending one
txmitcomplete interrupt for each packet (although this can be mitigated)].
For these broken drivers, move all to dev->poll().
For the rest of this text, we'll assume that dev->poll() only
processes receive events.
new methods introduce by NAPI
=============================
a) netif_rx_schedule(dev)
Called by an IRQ handler to schedule a poll for device
b) netif_rx_schedule_prep(dev)
puts the device in a state which allows for it to be added to the
CPU polling list if it is up and running. You can look at this as
the first half of netif_rx_schedule(dev) above; the second half
being c) below.
c) __netif_rx_schedule(dev)
Add device to the poll list for this CPU; assuming that _prep above
has already been called and returned 1.
d) netif_rx_reschedule(dev, undo)
Called to reschedule polling for device specifically for some
deficient hardware. Read Appendix 2 for more details.
e) netif_rx_complete(dev)
Remove interface from the CPU poll list: it must be in the poll list
on current cpu. This primitive is called by dev->poll(), when
it completes its work. The device cannot be out of poll list at this
call, if it is then clearly it is a BUG(). You'll know ;->
All of the above methods are used below, so keep reading for clarity.
Device driver changes to be made when porting NAPI
==================================================
Below we describe what kind of changes are required for NAPI to work.
1) introduction of dev->poll() method
=====================================
This is the method that is invoked by the network core when it requests
for new packets from the driver. A driver is allowed to send upto
dev->quota packets by the current CPU before yielding to the network
subsystem (so other devices can also get opportunity to send to the stack).
dev->poll() prototype looks as follows:
int my_poll(struct net_device *dev, int *budget)
budget is the remaining number of packets the network subsystem on the
current CPU can send up the stack before yielding to other system tasks.
*Each driver is responsible for decrementing budget by the total number of
packets sent.
Total number of packets cannot exceed dev->quota.
dev->poll() method is invoked by the top layer, the driver just sends if it
can to the stack the packet quantity requested.
more on dev->poll() below after the interrupt changes are explained.
2) registering dev->poll() method
===================================
dev->poll should be set in the dev->probe() method.
e.g:
dev->open = my_open;
.
.
/* two new additions */
/* first register my poll method */
dev->poll = my_poll;
/* next register my weight/quanta; can be overridden in /proc */
dev->weight = 16;
.
.
dev->stop = my_close;
3) scheduling dev->poll()
=============================
This involves modifying the interrupt handler and the code
path which takes the packet off the NIC and sends them to the
stack.
it's important at this point to introduce the classical D Becker
interrupt processor:
------------------
static irqreturn_t
netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
{
struct net_device *dev = (struct net_device *)dev_instance;
struct my_private *tp = (struct my_private *)dev->priv;
int work_count = my_work_count;
status = read_interrupt_status_reg();
if (status == 0)
return IRQ_NONE; /* Shared IRQ: not us */
if (status == 0xffff)
return IRQ_HANDLED; /* Hot unplug */
if (status & error)
do_some_error_handling()
do {
acknowledge_ints_ASAP();
if (status & link_interrupt) {
spin_lock(&tp->link_lock);
do_some_link_stat_stuff();
spin_lock(&tp->link_lock);
}
if (status & rx_interrupt) {
receive_packets(dev);
}
if (status & rx_nobufs) {
make_rx_buffs_avail();
}
if (status & tx_related) {
spin_lock(&tp->lock);
tx_ring_free(dev);
if (tx_died)
restart_tx();
spin_unlock(&tp->lock);
}
status = read_interrupt_status_reg();
} while (!(status & error) || more_work_to_be_done);
return IRQ_HANDLED;
}
----------------------------------------------------------------------
We now change this to what is shown below to NAPI-enable it:
----------------------------------------------------------------------
static irqreturn_t
netdevice_interrupt(int irq, void *dev_id, struct pt_regs *regs)
{
struct net_device *dev = (struct net_device *)dev_instance;
struct my_private *tp = (struct my_private *)dev->priv;
status = read_interrupt_status_reg();
if (status == 0)
return IRQ_NONE; /* Shared IRQ: not us */
if (status == 0xffff)
return IRQ_HANDLED; /* Hot unplug */
if (status & error)
do_some_error_handling();
do {
/************************ start note *********************************/
acknowledge_ints_ASAP(); // dont ack rx and rxnobuff here
/************************ end note *********************************/
if (status & link_interrupt) {
spin_lock(&tp->link_lock);
do_some_link_stat_stuff();
spin_unlock(&tp->link_lock);
}
/************************ start note *********************************/
if (status & rx_interrupt || (status & rx_nobuffs)) {
if (netif_rx_schedule_prep(dev)) {
/* disable interrupts caused
* by arriving packets */
disable_rx_and_rxnobuff_ints();
/* tell system we have work to be done. */
__netif_rx_schedule(dev);
} else {
printk("driver bug! interrupt while in poll\n");
/* FIX by disabling interrupts */
disable_rx_and_rxnobuff_ints();
}
}
/************************ end note note *********************************/
if (status & tx_related) {
spin_lock(&tp->lock);
tx_ring_free(dev);
if (tx_died)
restart_tx();
spin_unlock(&tp->lock);
}
status = read_interrupt_status_reg();
/************************ start note *********************************/
} while (!(status & error) || more_work_to_be_done(status));
/************************ end note note *********************************/
return IRQ_HANDLED;
}
---------------------------------------------------------------------
We note several things from above:
I) Any interrupt source which is caused by arriving packets is now
turned off when it occurs. Depending on the hardware, there could be
several reasons that arriving packets would cause interrupts; these are the
interrupt sources we wish to avoid. The two common ones are a) a packet
arriving (rxint) b) a packet arriving and finding no DMA buffers available
(rxnobuff) .
This means also acknowledge_ints_ASAP() will not clear the status
register for those two items above; clearing is done in the place where
proper work is done within NAPI; at the poll() and refill_rx_ring()
discussed further below.
netif_rx_schedule_prep() returns 1 if device is in running state and
gets successfully added to the core poll list. If we get a zero value
we can _almost_ assume are already added to the list (instead of not running.
Logic based on the fact that you shouldn't get interrupt if not running)
We rectify this by disabling rx and rxnobuf interrupts.
II) that receive_packets(dev) and make_rx_buffs_avail() may have disappeared.
These functionalities are still around actually......
infact, receive_packets(dev) is very close to my_poll() and
make_rx_buffs_avail() is invoked from my_poll()
4) converting receive_packets() to dev->poll()
===============================================
We need to convert the classical D Becker receive_packets(dev) to my_poll()
First the typical receive_packets() below:
-------------------------------------------------------------------
/* this is called by interrupt handler */
static void receive_packets (struct net_device *dev)
{
struct my_private *tp = (struct my_private *)dev->priv;
rx_ring = tp->rx_ring;
cur_rx = tp->cur_rx;
int entry = cur_rx % RX_RING_SIZE;
int received = 0;
int rx_work_limit = tp->dirty_rx + RX_RING_SIZE - tp->cur_rx;
while (rx_ring_not_empty) {
u32 rx_status;
unsigned int rx_size;
unsigned int pkt_size;
struct sk_buff *skb;
/* read size+status of next frame from DMA ring buffer */
/* the number 16 and 4 are just examples */
rx_status = le32_to_cpu (*(u32 *) (rx_ring + ring_offset));
rx_size = rx_status >> 16;
pkt_size = rx_size - 4;
/* process errors */
if ((rx_size > (MAX_ETH_FRAME_SIZE+4)) ||
(!(rx_status & RxStatusOK))) {
netdrv_rx_err (rx_status, dev, tp, ioaddr);
return;
}
if (--rx_work_limit < 0)
break;
/* grab a skb */
skb = dev_alloc_skb (pkt_size + 2);
if (skb) {
.
.
netif_rx (skb);
.
.
} else { /* OOM */
/*seems very driver specific ... some just pass
whatever is on the ring already. */
}
/* move to the next skb on the ring */
entry = (++tp->cur_rx) % RX_RING_SIZE;
received++ ;
}
/* store current ring pointer state */
tp->cur_rx = cur_rx;
/* Refill the Rx ring buffers if they are needed */
refill_rx_ring();
.
.
}
-------------------------------------------------------------------
We change it to a new one below; note the additional parameter in
the call.
-------------------------------------------------------------------
/* this is called by the network core */
static int my_poll (struct net_device *dev, int *budget)
{
struct my_private *tp = (struct my_private *)dev->priv;
rx_ring = tp->rx_ring;
cur_rx = tp->cur_rx;
int entry = cur_rx % RX_BUF_LEN;
/* maximum packets to send to the stack */

2) We have a done and not_done state.
3) instead of netif_rx() we call netif_receive_skb() to pass the skb.
4) we have a new way of handling oom condition
5) A new outer for (;;) loop has been added. This serves the purpose of
ensuring that if a new packet has come in, after we are all set and done,
and we have not exceeded our quota that we continue sending packets up.

a)
if (tp->cur_rx - tp->dirty_rx > RX_RING_SIZE/2 ||
tp->rx_buffers[tp->dirty_rx % RX_RING_SIZE].skb == NULL)
refill_rx_ring(dev);
/* If RX ring is not full we are still out of memory.
Restart the timer again. Else we re-add ourselves
to the master poll list.
*/
if (tp->rx_buffers[tp->dirty_rx % RX_RING_SIZE].skb == NULL)
restart_timer();
else netif_rx_schedule(dev); /* we are back on the poll list */
5) dev->close() and dev->suspend() issues
==========================================
The driver writer needn't worry about this; the top net layer takes
care of it.
6) Adding new Stats to /proc
=============================
In order to debug some of the new features, we introduce new stats
that need to be collected.
TODO: Fill this later.
APPENDIX 1: discussion on using ethernet HW FC
==============================================
Most chips with FC only send a pause packet when they run out of Rx buffers.
Since packets are pulled off the DMA ring by a softirq in NAPI,
if the system is slow in grabbing them and we have a high input
rate (faster than the system's capacity to remove packets), then theoretically
there will only be one rx interrupt for all packets during a given packetstorm.
Under low load, we might have a single interrupt per packet.
FC should be programmed to apply in the case when the system cant pull out
packets fast enough i.e send a pause only when you run out of rx buffers.
Note FC in itself is a good solution but we have found it to not be
much of a commodity feature (both in NICs and switches) and hence falls
under the same category as using NIC based mitigation. Also, experiments
indicate that it's much harder to resolve the resource allocation
issue (aka lazy receiving that NAPI offers) and hence quantify its usefulness
proved harder. In any case, FC works even better with NAPI but is not
necessary.
APPENDIX 2: the "rotting packet" race-window avoidance scheme
=============================================================
There are two types of associations seen here
1) status/int which honors level triggered IRQ
If a status bit for receive or rxnobuff is set and the corresponding
interrupt-enable bit is not on, then no interrupts will be generated. However,
as soon as the "interrupt-enable" bit is unmasked, an immediate interrupt is
generated. [assuming the status bit was not turned off].
Generally the concept of level triggered IRQs in association with a status and
interrupt-enable CSR register set is used to avoid the race.
If we take the example of the tulip:
"pending work" is indicated by the status bit(CSR5 in tulip).
the corresponding interrupt bit (CSR7 in tulip) might be turned off (but
the CSR5 will continue to be turned on with new packet arrivals even if
we clear it the first time)
Very important is the fact that if we turn on the interrupt bit on when
status is set that an immediate irq is triggered.
If we cleared the rx ring and proclaimed there was "no more work
to be done" and then went on to do a few other things; then when we enable
interrupts, there is a possibility that a new packet might sneak in during
this phase. It helps to look at the pseudo code for the tulip poll
routine:
--------------------------
do {
ACK;
while (ring_is_not_empty()) {
work-work-work
if quota is exceeded: exit, no touching irq status/mask
}
/* No packets, but new can arrive while we are doing this*/
CSR5 := read
if (CSR5 is not set) {
/* If something arrives in this narrow window here,
* where the comments are ;-> irq will be generated */
unmask irqs;
exit poll;
}
} while (rx_status_is_set);
------------------------
CSR5 bit of interest is only the rx status.
If you look at the last if statement:
you just finished grabbing all the packets from the rx ring .. you check if
status bit says there are more packets just in ... it says none; you then
enable rx interrupts again; if a new packet just came in during this check,
we are counting that CSR5 will be set in that small window of opportunity
and that by re-enabling interrupts, we would actually trigger an interrupt
to register the new packet for processing.
[The above description nay be very verbose, if you have better wording
that will make this more understandable, please suggest it.]
2) non-capable hardware
These do not generally respect level triggered IRQs. Normally,
irqs may be lost while being masked and the only way to leave poll is to do
a double check for new input after netif_rx_complete() is invoked
and re-enable polling (after seeing this new input).
Sample code:
---------
.
.
restart_poll:
while (ring_is_not_empty()) {
work-work-work
if quota is exceeded: exit, not touching irq status/mask
}
.
.
.
enable_rx_interrupts()
netif_rx_complete(dev);
if (ring_has_new_packet() && netif_rx_reschedule(dev, received)) {
disable_rx_and_rxnobufs()
goto restart_poll
} while (rx_status_is_set);
---------
Basically netif_rx_complete() removes us from the poll list, but because a
new packet which will never be caught due to the possibility of a race
might come in, we attempt to re-add ourselves to the poll list.
APPENDIX 3: Scheduling issues.
==============================
As seen NAPI moves processing to softirq level. Linux uses the ksoftirqd as the
general solution to schedule softirq's to run before next interrupt and by putting
them under scheduler control. Also this prevents consecutive softirq's from
monopolize the CPU. This also have the effect that the priority of ksoftirq needs
to be considered when running very CPU-intensive applications and networking to
get the proper balance of softirq/user balance. Increasing ksoftirq priority to 0
(eventually more) is reported cure problems with low network performance at high
CPU load.

The Digi International RightSwitch SE-X (dgrs) Device Driver
This is a Linux driver for the Digi International RightSwitch SE-X
EISA and PCI boards. These are 4 (EISA) or 6 (PCI) port Ethernet
switches and a NIC combined into a single board. This driver can
be compiled into the kernel statically or as a loadable module.
There is also a companion management tool, called "xrightswitch".
The management tool lets you watch the performance graphically,
as well as set the SNMP agent IP and IPX addresses, IEEE Spanning
Tree, and Aging time. These can also be set from the command line
when the driver is loaded. The driver command line options are:
debug=NNN Debug printing level
dma=0/1 Disable/Enable DMA on PCI card
spantree=0/1 Disable/Enable IEEE spanning tree
hashexpire=NNN Change address aging time (default 300 seconds)
ipaddr=A,B,C,D Set SNMP agent IP address i.e. 199,86,8,221
iptrap=A,B,C,D Set SNMP agent IP trap address i.e. 199,86,8,221
ipxnet=NNN Set SNMP agent IPX network number
nicmode=0/1 Disable/Enable multiple NIC mode
There is also a tool for setting up input and output packet filters
on each port, called "dgrsfilt".
Both the management tool and the filtering tool are available
separately from the following FTP site:
ftp://ftp.dgii.com/drivers/rightswitch/linux/
When nicmode=1, the board and driver operate as 4 or 6 individual
NIC ports (eth0...eth5) instead of as a switch. All switching

It also supports logging to multiple remote agents by specifying
parameters for the multiple agents separated by semicolons and the
complete string enclosed in "quotes", thusly:
modprobe netconsole netconsole="@/,@10.0.0.2/;@/eth1,6892@10.0.0.3/"
Built-in netconsole starts immediately after the TCP stack is
initialized and attempts to bring up the supplied dev at the supplied
address.
The remote host can run either 'netcat -u -l -p <port>' or syslogd.
Dynamic reconfiguration:
========================
Dynamic reconfigurability is a useful addition to netconsole that enables
remote logging targets to be dynamically added, removed, or have their
parameters reconfigured at runtime from a configfs-based userspace interface.
[ Note that the parameters of netconsole targets that were specified/created
from the boot/module option are not exposed via this interface, and hence
cannot be modified dynamically. ]
To include this feature, select CONFIG_NETCONSOLE_DYNAMIC when building the
netconsole module (or kernel, if netconsole is built-in).
Some examples follow (where configfs is mounted at the /sys/kernel/config
mountpoint).
To add a remote logging target (target names can be arbitrary):
cd /sys/kernel/config/netconsole/
mkdir target1
Note that newly created targets have default parameter values (as mentioned
above) and are disabled by default -- they must first be enabled by writing
"1" to the "enabled" attribute (usually after setting parameters accordingly)
as described below.
To remove a target:
rmdir /sys/kernel/config/netconsole/othertarget/
The interface exposes these parameters of a netconsole target to userspace:
enabled Is this target currently enabled? (read-write)
dev_name Local network interface name (read-write)
local_port Source UDP port to use (read-write)
remote_port Remote agent's UDP port (read-write)
local_ip Source IP address to use (read-write)
remote_ip Remote agent's IP address (read-write)
local_mac Local interface's MAC address (read-only)
remote_mac Remote agent's MAC address (read-write)
The "enabled" attribute is also used to control whether the parameters of
a target can be updated or not -- you can modify the parameters of only
disabled targets (i.e. if "enabled" is 0).
To update a target's parameters:
cat enabled # check if enabled is 1
echo 0 > enabled # disable the target (if required)
echo eth2 > dev_name # set local interface
echo 10.0.0.4 > remote_ip # update some parameter
echo cb:a9:87:65:43:21 > remote_mac # update more parameters
echo 1 > enabled # enable target again
You can also update the local interface dynamically. This is especially
useful if you want to use interfaces that have newly come up (and may not
have existed when netconsole was loaded / initialized).
Miscellaneous notes:
====================
WARNING: the default target ethernet setting uses the broadcast
ethernet address to send packets, which can cause increased load on
other systems on the same ethernet segment.
TIP: some LAN switches may be configured to suppress ethernet broadcasts
so it is advised to explicitly specify the remote agents' MAC addresses
from the config parameters passed to netconsole.
TIP: to find out the MAC address of, say, 10.0.0.2, you may try using:
ping -c 1 10.0.0.2 ; /sbin/arp -n | grep 10.0.0.2
TIP: in case the remote logging agent is on a separate LAN subnet than
the sender, it is suggested to try specifying the MAC address of the
default gateway (you may use /sbin/route -n to find it out) as the
remote MAC address instead.
NOTE: the network device (eth1 in the above case) can run any kind
of other network traffic, netconsole is not intrusive. Netconsole
might cause slight delays in other traffic if the volume of kernel
messages is high, but should have no other impact.
NOTE: if you find that the remote logging agent is not receiving or
printing all messages from the sender, it is likely that you have set
the "console_loglevel" parameter (on the sender) to only send high
priority messages to the console. You can change this at runtime using:
dmesg -n 8
or by specifying "debug" on the kernel command line at boot, to send
all kernel messages to the console. A specific value for this parameter
can also be set using the "loglevel" kernel boot option. See the
dmesg(8) man page and Documentation/kernel-parameters.txt for details.
Netconsole was designed to be as instantaneous as possible, to
enable the logging of even the most critical kernel bugs. It works
from IRQ contexts as well, and does not enable interrupts while

- bank-width : Width of the flash data bus in bytes. Required
for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
For JEDEC compatible devices, the following additional properties
are defined:
Recommended properties :
- vendor-id : Contains the flash chip's vendor id (1 byte).
- device-id : Contains the flash chip's device id (1 byte).
- partitions : Several pairs of 32-bit values where the first value is
partition's offset from the start of the device and the second one is
partition size in bytes with LSB used to signify a read only
partition (so, the partition size should always be an even number).
- partition-names : The list of concatenated zero terminated strings
representing the partition names.
- probe-type : The type of probe which should be done for the chip
(JEDEC vs CFI actually). Valid ONLY for NOR flashes.
In addition to the information on the flash bank itself, the
device tree may optionally contain additional information
describing partitions of the flash address space. This can be
used on platforms which have strong conventions about which
portions of the flash are used for what purposes, but which don't
use an on-flash partition table such as RedBoot.
Example:
Each partition is represented as a sub-node of the flash device.
Each node's name represents the name of the corresponding
partition of the flash device.
flash@ff000000 {
device_type = "rom";
compatible = "direct-mapped";
probe-type = "CFI";
reg = <ff000000 01000000>;

Flash partitions
- reg : The partition's offset and size within the flash bank.
- label : (optional) The label / name for this flash partition.
If omitted, the label is taken from the node name (excluding
the unit address).
- read-only : (optional) This parameter, if present, is a hint to
Linux that this flash partition should only be mounted
read-only. This is usually used for flash partitions
containing early-boot firmware images or data which should not
be clobbered.
Example:
flash@ff000000 {

viii) Multi-User RAM (MURAM)
The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
Ranges must be set up subject to the following restrictions:
- Children's reg nodes must be offsets from the start of all muram, even
if the user-data area does not begin at zero.
- If multiple range entries are used, the difference between the parent
address and the child address must be the same in all, so that a single
mapping can cover them all while maintaining the ability to determine
CPM-side offsets with pointer subtraction. It is recommended that
multiple range entries not be used.
- A child address of zero must be translatable, even if no reg resources
contain it.
A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
indicate the portion of muram that is usable by the OS for arbitrary
purposes. The data node may have an arbitrary number of reg resources,
all of which contribute to the allocatable muram pool.
Example, based on mpc8272:
muram@0 {
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 0 10000>;
data@0 {
compatible = "fsl,cpm-muram-data";
reg = <0 2000 9800 800>;
};
};
m) Chipselect/Local Bus
Properties:
- name : Should be localbus
- #address-cells : Should be either two or three. The first cell is the
chipselect number, and the remaining cells are the
offset into the chipselect.
- #size-cells : Either one or two, depending on how large each chipselect
can be.
- ranges : Each range corresponds to a single chipselect, and cover
the entire access window as configured.
Example:
localbus@f0010100 {
compatible = "fsl,mpc8272ads-localbus",
"fsl,mpc8272-localbus",
"fsl,pq2-localbus";
#address-cells = <2>;
#size-cells = <1>;
reg = <f0010100 40>;
ranges = <0 0 fe000000 02000000

n) 4xx/Axon EMAC ethernet nodes
The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
the Axon bridge. To operate this needs to interact with a ths
special McMAL DMA controller, and sometimes an RGMII or ZMII

(440EP). phandle of the EMAC to use to drive the
MDIO lines for the PHY used by this EMAC.
- zmii-device : 1 cell, required iff connected to a ZMII. phandle of
the ZMII device node
- zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
channel or 0xffffffff if ZMII is only used for MDIO.
- rgmii-device : 1 cell, required iff connected to an RGMII. phandle
of the RGMII device node.
For Axon: phandle of plb5/plb4/opb/rgmii
- rgmii-channel : 1 cell, required iff connected to an RGMII. Which
RGMII channel is used by this EMAC.
Fox Axon: present, whatever value is appropriate for each
EMAC, that is the content of the current (bogus) "phy-port"
property.
Recommended properties:
- linux,network-index : This is the intended "index" of this
network device. This is used by the bootwrapper to interpret
MAC addresses passed by the firmware when no information other

Optional properties:
- phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
a search is performed.
- phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
for, used if phy-address is absent. bit 0x00000001 is
MDIO address 0.
For Axon it can be absent, thouugh my current driver
doesn't handle phy-address yet so for now, keep
0x00ffffff in it.
- rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
operations (if absent the value is the same as
rx-fifo-size). For Axon, either absent or 2048.
- tx-fifo-size-gige : 1 cell, Tx fifo size in bytes for 1000 Mb/sec
operations (if absent the value is the same as
tx-fifo-size). For Axon, either absent or 2048.

tx-fifo-size = <800>;
phy-mode = "rmii";
phy-map = <00000001>;
zmii-device = <&ZMII0>;
zmii-channel = <0>;
};
ii) McMAL node
Required properties:
- device_type : "dma-controller"
- compatible : compatible list, containing 2 entries, first is
"ibm,mcmal-CHIP" where CHIP is the host ASIC (like
emac) and the second is either "ibm,mcmal" or

For Axon, "ibm,mcmal-axon","ibm,mcmal2"
- interrupts : <interrupt mapping for the MAL interrupts sources:
5 sources: tx_eob, rx_eob, serr, txde, rxde>.
For Axon: This is _different_ from the current
firmware. We use the "delayed" interrupts for txeob
and rxeob. Thus we end up with mapping those 5 MPIC
interrupts, all level positive sensitive: 10, 11, 32,
33, 34 (in decimal)
- dcr-reg : < DCR registers range >
- dcr-parent : if needed for dcr-reg
- num-tx-chans : 1 cell, number of Tx channels
- num-rx-chans : 1 cell, number of Rx channels
iii) ZMII node
Required properties:
- compatible : compatible list, containing 2 entries, first is
"ibm,zmii-CHIP" where CHIP is the host ASIC (like
EMAC) and the second is "ibm,zmii".
For Axon, there is no ZMII node.
- reg : <registers mapping>
iv) RGMII node

rfkill - RF switch subsystem support
====================================
1 Implementation details
2 Driver support
3 Userspace support
===============================================================================
1: Implementation details
The rfkill switch subsystem offers support for keys often found on laptops
to enable wireless devices like WiFi and Bluetooth.
This is done by providing the user 3 possibilities:
1 - The rfkill system handles all events; userspace is not aware of events.
2 - The rfkill system handles all events; userspace is informed about the events.
3 - The rfkill system does not handle events; userspace handles all events.
The buttons to enable and disable the wireless radios are important in
situations where the user is for example using his laptop on a location where
wireless radios _must_ be disabled (e.g. airplanes).
Because of this requirement, userspace support for the keys should not be
made mandatory. Because userspace might want to perform some additional smarter
tasks when the key is pressed, rfkill still provides userspace the possibility
to take over the task to handle the key events.
The system inside the kernel has been split into 2 separate sections:
1 - RFKILL
2 - RFKILL_INPUT
The first option enables rfkill support and will make sure userspace will
be notified of any events through the input device. It also creates several
sysfs entries which can be used by userspace. See section "Userspace support".
The second option provides an rfkill input handler. This handler will
listen to all rfkill key events and will toggle the radio accordingly.
With this option enabled userspace could either do nothing or simply
perform monitoring tasks.
====================================
2: Driver support
To build a driver with rfkill subsystem support, the driver should
depend on the Kconfig symbol RFKILL; it should _not_ depend on
RKFILL_INPUT.
Unless key events trigger an interrupt to which the driver listens, polling
will be required to determine the key state changes. For this the input
layer providers the input-polldev handler.
A driver should implement a few steps to correctly make use of the
rfkill subsystem. First for non-polling drivers:
- rfkill_allocate()
- input_allocate_device()
- rfkill_register()
- input_register_device()
For polling drivers:
- rfkill_allocate()
- input_allocate_polled_device()
- rfkill_register()
- input_register_polled_device()
When a key event has been detected, the correct event should be
sent over the input device which has been registered by the driver.
====================================
3: Userspace support
For each key an input device will be created which will send out the correct
key event when the rfkill key has been pressed.
The following sysfs entries will be created:
name: Name assigned by driver to this key (interface or driver name).
type: Name of the key type ("wlan", "bluetooth", etc).
state: Current state of the key. 1: On, 0: Off.
claim: 1: Userspace handles events, 0: Kernel handles events
Both the "state" and "claim" entries are also writable. For the "state" entry
this means that when 1 or 0 is written all radios, not yet in the requested
state, will be will be toggled accordingly.
For the "claim" entry writing 1 to it means that the kernel no longer handles
key events even though RFKILL_INPUT input was enabled. When "claim" has been
set to 0, userspace should make sure that it listens for the input events or
check the sysfs "state" entry regularly to correctly perform the required
tasks when the rkfill key is pressed.

Authorizing (or not) your USB devices to connect to the system
(C) 2007 Inaky Perez-Gonzalez <inaky@linux.intel.com> Intel Corporation
This feature allows you to control if a USB device can be used (or
not) in a system. This feature will allow you to implement a lock-down
of USB devices, fully controlled by user space.
As of now, when a USB device is connected it is configured and
it's interfaces inmediately made available to the users. With this
modification, only if root authorizes the device to be configured will
then it be possible to use it.
Usage:
Authorize a device to connect:
$ echo 1 > /sys/usb/devices/DEVICE/authorized
Deauthorize a device:
$ echo 0 > /sys/usb/devices/DEVICE/authorized
Set new devices connected to hostX to be deauthorized by default (ie:
lock down):
$ echo 0 > /sys/bus/devices/usbX/authorized_default
Remove the lock down:
$ echo 1 > /sys/bus/devices/usbX/authorized_default
By default, Wired USB devices are authorized by default to
connect. Wireless USB hosts deauthorize by default all new connected
devices (this is so because we need to do an authentication phase
before authorizing).
Example system lockdown (lame)
-----------------------
Imagine you want to implement a lockdown so only devices of type XYZ
can be connected (for example, it is a kiosk machine with a visible
USB port):
boot up
rc.local ->
for host in /sys/bus/devices/usb*
do
echo 0 > $host/authorized_default
done
Hookup an script to udev, for new USB devices
if device_is_my_type $DEV
then
echo 1 > $device_path/authorized
done
Now, device_is_my_type() is where the juice for a lockdown is. Just
checking if the class, type and protocol match something is the worse
security verification you can make (or the best, for someone willing
to break it). If you need something secure, use crypto and Certificate
Authentication or stuff like that. Something simple for an storage key
could be:
function device_is_my_type()
{
echo 1 > authorized # temporarily authorize it
# FIXME: make sure none can mount it
mount DEVICENODE /mntpoint
sum=$(md5sum /mntpoint/.signature)
if [ $sum = $(cat /etc/lockdown/keysum) ]
then
echo "We are good, connected"
umount /mntpoint
# Other stuff so others can use it
else
echo 0 > authorized
fi
}
Of course, this is lame, you'd want to do a real certificate
verification stuff with PKI, so you don't depend on a shared secret,
etc, but you get the idea. Anybody with access to a device gadget kit
can fake descriptors and device info. Don't trust that. You are
welcome.

Power Management for USB
Alan Stern <stern@rowland.harvard.edu>
October 5, 2007
What is Power Management?
-------------------------
Power Management (PM) is the practice of saving energy by suspending
parts of a computer system when they aren't being used. While a
component is "suspended" it is in a nonfunctional low-power state; it
might even be turned off completely. A suspended component can be
"resumed" (returned to a functional full-power state) when the kernel
needs to use it. (There also are forms of PM in which components are
placed in a less functional but still usable state instead of being
suspended; an example would be reducing the CPU's clock rate. This
document will not discuss those other forms.)
When the parts being suspended include the CPU and most of the rest of
the system, we speak of it as a "system suspend". When a particular
device is turned off while the system as a whole remains running, we
call it a "dynamic suspend" (also known as a "runtime suspend" or
"selective suspend"). This document concentrates mostly on how
dynamic PM is implemented in the USB subsystem, although system PM is
covered to some extent (see Documentation/power/*.txt for more
information about system PM).
Note: Dynamic PM support for USB is present only if the kernel was
built with CONFIG_USB_SUSPEND enabled. System PM support is present
only if the kernel was built with CONFIG_SUSPEND or CONFIG_HIBERNATION
enabled.
What is Remote Wakeup?
----------------------
When a device has been suspended, it generally doesn't resume until
the computer tells it to. Likewise, if the entire computer has been
suspended, it generally doesn't resume until the user tells it to, say
by pressing a power button or opening the cover.
However some devices have the capability of resuming by themselves, or
asking the kernel to resume them, or even telling the entire computer
to resume. This capability goes by several names such as "Wake On
LAN"; we will refer to it generically as "remote wakeup". When a
device is enabled for remote wakeup and it is suspended, it may resume
itself (or send a request to be resumed) in response to some external
event. Examples include a suspended keyboard resuming when a key is
pressed, or a suspended USB hub resuming when a device is plugged in.
When is a USB device idle?
--------------------------
A device is idle whenever the kernel thinks it's not busy doing
anything important and thus is a candidate for being suspended. The
exact definition depends on the device's driver; drivers are allowed
to declare that a device isn't idle even when there's no actual
communication taking place. (For example, a hub isn't considered idle
unless all the devices plugged into that hub are already suspended.)
In addition, a device isn't considered idle so long as a program keeps
its usbfs file open, whether or not any I/O is going on.
If a USB device has no driver, its usbfs file isn't open, and it isn't
being accessed through sysfs, then it definitely is idle.
Forms of dynamic PM
-------------------
Dynamic suspends can occur in two ways: manual and automatic.
"Manual" means that the user has told the kernel to suspend a device,
whereas "automatic" means that the kernel has decided all by itself to
suspend a device. Automatic suspend is called "autosuspend" for
short. In general, a device won't be autosuspended unless it has been
idle for some minimum period of time, the so-called idle-delay time.
Of course, nothing the kernel does on its own initiative should
prevent the computer or its devices from working properly. If a
device has been autosuspended and a program tries to use it, the
kernel will automatically resume the device (autoresume). For the
same reason, an autosuspended device will usually have remote wakeup
enabled, if the device supports remote wakeup.
It is worth mentioning that many USB drivers don't support
autosuspend. In fact, at the time of this writing (Linux 2.6.23) the
only drivers which do support it are the hub driver, kaweth, asix,
usblp, usblcd, and usb-skeleton (which doesn't count). If a
non-supporting driver is bound to a device, the device won't be
autosuspended. In effect, the kernel pretends the device is never
idle.
We can categorize power management events in two broad classes:
external and internal. External events are those triggered by some
agent outside the USB stack: system suspend/resume (triggered by
userspace), manual dynamic suspend/resume (also triggered by
userspace), and remote wakeup (triggered by the device). Internal
events are those triggered within the USB stack: autosuspend and
autoresume.
The user interface for dynamic PM
---------------------------------
The user interface for controlling dynamic PM is located in the power/
subdirectory of each USB device's sysfs directory, that is, in
/sys/bus/usb/devices/.../power/ where "..." is the device's ID. The
relevant attribute files are: wakeup, level, and autosuspend.
power/wakeup
This file is empty if the device does not support
remote wakeup. Otherwise the file contains either the
word "enabled" or the word "disabled", and you can
write those words to the file. The setting determines
whether or not remote wakeup will be enabled when the
device is next suspended. (If the setting is changed
while the device is suspended, the change won't take
effect until the following suspend.)
power/level
This file contains one of three words: "on", "auto",
or "suspend". You can write those words to the file
to change the device's setting.
"on" means that the device should be resumed and
autosuspend is not allowed. (Of course, system
suspends are still allowed.)
"auto" is the normal state in which the kernel is
allowed to autosuspend and autoresume the device.
"suspend" means that the device should remain
suspended, and autoresume is not allowed. (But remote
wakeup may still be allowed, since it is controlled
separately by the power/wakeup attribute.)
power/autosuspend
This file contains an integer value, which is the
number of seconds the device should remain idle before
the kernel will autosuspend it (the idle-delay time).
The default is 2. 0 means to autosuspend as soon as
the device becomes idle, and -1 means never to
autosuspend. You can write a number to the file to
change the autosuspend idle-delay time.
Writing "-1" to power/autosuspend and writing "on" to power/level do
essentially the same thing -- they both prevent the device from being
autosuspended. Yes, this is a redundancy in the API.
(In 2.6.21 writing "0" to power/autosuspend would prevent the device
from being autosuspended; the behavior was changed in 2.6.22. The
power/autosuspend attribute did not exist prior to 2.6.21, and the
power/level attribute did not exist prior to 2.6.22.)
Changing the default idle-delay time
------------------------------------
The default autosuspend idle-delay time is controlled by a module
parameter in usbcore. You can specify the value when usbcore is
loaded. For example, to set it to 5 seconds instead of 2 you would
do:
modprobe usbcore autosuspend=5
Equivalently, you could add to /etc/modprobe.conf a line saying:
options usbcore autosuspend=5
Some distributions load the usbcore module very early during the boot
process, by means of a program or script running from an initramfs
image. To alter the parameter value you would have to rebuild that
image.
If usbcore is compiled into the kernel rather than built as a loadable
module, you can add
usbcore.autosuspend=5
to the kernel's boot command line.
Finally, the parameter value can be changed while the system is
running. If you do:
echo 5 >/sys/module/usbcore/parameters/autosuspend
then each new USB device will have its autosuspend idle-delay
initialized to 5. (The idle-delay values for already existing devices
will not be affected.)
Setting the initial default idle-delay to -1 will prevent any
autosuspend of any USB device. This is a simple alternative to
disabling CONFIG_USB_SUSPEND and rebuilding the kernel, and it has the
added benefit of allowing you to enable autosuspend for selected
devices.
Warnings
--------
The USB specification states that all USB devices must support power
management. Nevertheless, the sad fact is that many devices do not
support it very well. You can suspend them all right, but when you
try to resume them they disconnect themselves from the USB bus or
they stop working entirely. This seems to be especially prevalent
among printers and scanners, but plenty of other types of device have
the same deficiency.
For this reason, by default the kernel disables autosuspend (the
power/level attribute is initialized to "on") for all devices other
than hubs. Hubs, at least, appear to be reasonably well-behaved in
this regard.
(In 2.6.21 and 2.6.22 this wasn't the case. Autosuspend was enabled
by default for almost all USB devices. A number of people experienced
problems as a result.)
This means that non-hub devices won't be autosuspended unless the user
or a program explicitly enables it. As of this writing there aren't
any widespread programs which will do this; we hope that in the near
future device managers such as HAL will take on this added
responsibility. In the meantime you can always carry out the
necessary operations by hand or add them to a udev script. You can
also change the idle-delay time; 2 seconds is not the best choice for
every device.
Sometimes it turns out that even when a device does work okay with
autosuspend there are still problems. For example, there are
experimental patches adding autosuspend support to the usbhid driver,
which manages keyboards and mice, among other things. Tests with a
number of keyboards showed that typing on a suspended keyboard, while
causing the keyboard to do a remote wakeup all right, would
nonetheless frequently result in lost keystrokes. Tests with mice
showed that some of them would issue a remote-wakeup request in
response to button presses but not to motion, and some in response to
neither.
The kernel will not prevent you from enabling autosuspend on devices
that can't handle it. It is even possible in theory to damage a
device by suspending it at the wrong time -- for example, suspending a
USB hard disk might cause it to spin down without parking the heads.
(Highly unlikely, but possible.) Take care.
The driver interface for Power Management
-----------------------------------------
The requirements for a USB driver to support external power management
are pretty modest; the driver need only define
.suspend
.resume
.reset_resume
methods in its usb_driver structure, and the reset_resume method is
optional. The methods' jobs are quite simple:
The suspend method is called to warn the driver that the
device is going to be suspended. If the driver returns a
negative error code, the suspend will be aborted. Normally
the driver will return 0, in which case it must cancel all
outstanding URBs (usb_kill_urb()) and not submit any more.
The resume method is called to tell the driver that the
device has been resumed and the driver can return to normal
operation. URBs may once more be submitted.
The reset_resume method is called to tell the driver that
the device has been resumed and it also has been reset.
The driver should redo any necessary device initialization,
since the device has probably lost most or all of its state
(although the interfaces will be in the same altsettings as
before the suspend).
The reset_resume method is used by the USB Persist facility (see
Documentation/usb/persist.txt) and it can also be used under certain
circumstances when CONFIG_USB_PERSIST is not enabled. Currently, if a
device is reset during a resume and the driver does not have a
reset_resume method, the driver won't receive any notification about
the resume. Later kernels will call the driver's disconnect method;
2.6.23 doesn't do this.
USB drivers are bound to interfaces, so their suspend and resume
methods get called when the interfaces are suspended or resumed. In
principle one might want to suspend some interfaces on a device (i.e.,
force the drivers for those interface to stop all activity) without
suspending the other interfaces. The USB core doesn't allow this; all
interfaces are suspended when the device itself is suspended and all
interfaces are resumed when the device is resumed. It isn't possible
to suspend or resume some but not all of a device's interfaces. The
closest you can come is to unbind the interfaces' drivers.
The driver interface for autosuspend and autoresume
---------------------------------------------------
To support autosuspend and autoresume, a driver should implement all
three of the methods listed above. In addition, a driver indicates
that it supports autosuspend by setting the .supports_autosuspend flag
in its usb_driver structure. It is then responsible for informing the
USB core whenever one of its interfaces becomes busy or idle. The
driver does so by calling these three functions:
int usb_autopm_get_interface(struct usb_interface *intf);
void usb_autopm_put_interface(struct usb_interface *intf);
int usb_autopm_set_interface(struct usb_interface *intf);
The functions work by maintaining a counter in the usb_interface
structure. When intf->pm_usage_count is > 0 then the interface is
deemed to be busy, and the kernel will not autosuspend the interface's
device. When intf->pm_usage_count is <= 0 then the interface is
considered to be idle, and the kernel may autosuspend the device.
(There is a similar pm_usage_count field in struct usb_device,
associated with the device itself rather than any of its interfaces.
This field is used only by the USB core.)
The driver owns intf->pm_usage_count; it can modify the value however
and whenever it likes. A nice aspect of the usb_autopm_* routines is
that the changes they make are protected by the usb_device structure's
PM mutex (udev->pm_mutex); however drivers may change pm_usage_count
without holding the mutex.
usb_autopm_get_interface() increments pm_usage_count and
attempts an autoresume if the new value is > 0 and the
device is suspended.
usb_autopm_put_interface() decrements pm_usage_count and
attempts an autosuspend if the new value is <= 0 and the
device isn't suspended.
usb_autopm_set_interface() leaves pm_usage_count alone.
It attempts an autoresume if the value is > 0 and the device
is suspended, and it attempts an autosuspend if the value is
<= 0 and the device isn't suspended.
There also are a couple of utility routines drivers can use:
usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
usb_autopm_set_interface(), which will attempt an autoresume.
usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
usb_autopm_set_interface(), which will attempt an autosuspend.
The conventional usage pattern is that a driver calls
usb_autopm_get_interface() in its open routine and
usb_autopm_put_interface() in its close or release routine. But
other patterns are possible.
The autosuspend attempts mentioned above will often fail for one
reason or another. For example, the power/level attribute might be
set to "on", or another interface in the same device might not be
idle. This is perfectly normal. If the reason for failure was that
the device hasn't been idle for long enough, a delayed workqueue
routine is automatically set up to carry out the operation when the
autosuspend idle-delay has expired.
Autoresume attempts also can fail. This will happen if power/level is
set to "suspend" or if the device doesn't manage to resume properly.
Unlike autosuspend, there's no delay for an autoresume.
Other parts of the driver interface
-----------------------------------
Sometimes a driver needs to make sure that remote wakeup is enabled
during autosuspend. For example, there's not much point
autosuspending a keyboard if the user can't cause the keyboard to do a
remote wakeup by typing on it. If the driver sets
intf->needs_remote_wakeup to 1, the kernel won't autosuspend the
device if remote wakeup isn't available or has been disabled through
the power/wakeup attribute. (If the device is already autosuspended,
though, setting this flag won't cause the kernel to autoresume it.
Normally a driver would set this flag in its probe method, at which
time the device is guaranteed not to be autosuspended.)
The usb_autopm_* routines have to run in a sleepable process context;
they must not be called from an interrupt handler or while holding a
spinlock. In fact, the entire autosuspend mechanism is not well geared
toward interrupt-driven operation. However there is one thing a
driver can do in an interrupt handler:
usb_mark_last_busy(struct usb_device *udev);
This sets udev->last_busy to the current time. udev->last_busy is the
field used for idle-delay calculations; updating it will cause any
pending autosuspend to be moved back. The usb_autopm_* routines will
also set the last_busy field to the current time.
Calling urb_mark_last_busy() from within an URB completion handler is
subject to races: The kernel may have just finished deciding the
device has been idle for long enough but not yet gotten around to
calling the driver's suspend method. The driver would have to be
responsible for synchronizing its suspend method with its URB
completion handler and causing the autosuspend to fail with -EBUSY if
an URB had completed too recently.
External suspend calls should never be allowed to fail in this way,
only autosuspend calls. The driver can tell them apart by checking
udev->auto_pm; this flag will be set to 1 for internal PM events
(autosuspend or autoresume) and 0 for external PM events.
Many of the ingredients in the autosuspend framework are oriented
towards interfaces: The usb_interface structure contains the
pm_usage_cnt field, and the usb_autopm_* routines take an interface
pointer as their argument. But somewhat confusingly, a few of the
pieces (usb_mark_last_busy() and udev->auto_pm) use the usb_device
structure instead. Drivers need to keep this straight; they can call
interface_to_usbdev() to find the device structure for a given
interface.
Locking requirements
--------------------
All three suspend/resume methods are always called while holding the
usb_device's PM mutex. For external events -- but not necessarily for
autosuspend or autoresume -- the device semaphore (udev->dev.sem) will
also be held. This implies that external suspend/resume events are
mutually exclusive with calls to probe, disconnect, pre_reset, and
post_reset; the USB core guarantees that this is true of internal
suspend/resume events as well.
If a driver wants to block all suspend/resume calls during some
critical section, it can simply acquire udev->pm_mutex.
Alternatively, if the critical section might call some of the
usb_autopm_* routines, the driver can avoid deadlock by doing:
down(&udev->dev.sem);
rc = usb_autopm_get_interface(intf);
and at the end of the critical section:
if (!rc)
usb_autopm_put_interface(intf);
up(&udev->dev.sem);
Holding the device semaphore will block all external PM calls, and the
usb_autopm_get_interface() will prevent any internal PM calls, even if
it fails. (Exercise: Why?)
The rules for locking order are:
Never acquire any device semaphore while holding any PM mutex.
Never acquire udev->pm_mutex while holding the PM mutex for
a device that isn't a descendant of udev.
In other words, PM mutexes should only be acquired going up the device
tree, and they should be acquired only after locking all the device
semaphores you need to hold. These rules don't matter to drivers very
much; they usually affect just the USB core.
Still, drivers do need to be careful. For example, many drivers use a
private mutex to synchronize their normal I/O activities with their
disconnect method. Now if the driver supports autosuspend then it
must call usb_autopm_put_interface() from somewhere -- maybe from its
close method. It should make the call while holding the private mutex,
since a driver shouldn't call any of the usb_autopm_* functions for an
interface from which it has been unbound.
But the usb_autpm_* routines always acquire the device's PM mutex, and
consequently the locking order has to be: private mutex first, PM
mutex second. Since the suspend method is always called with the PM
mutex held, it mustn't try to acquire the private mutex. It has to
synchronize with the driver's I/O activities in some other way.
Interaction between dynamic PM and system PM
--------------------------------------------
Dynamic power management and system power management can interact in
a couple of ways.
Firstly, a device may already be manually suspended or autosuspended
when a system suspend occurs. Since system suspends are supposed to
be as transparent as possible, the device should remain suspended
following the system resume. The 2.6.23 kernel obeys this principle
for manually suspended devices but not for autosuspended devices; they
do get resumed when the system wakes up. (Presumably they will be
autosuspended again after their idle-delay time expires.) In later
kernels this behavior will be fixed.
(There is an exception. If a device would undergo a reset-resume
instead of a normal resume, and the device is enabled for remote
wakeup, then the reset-resume takes place even if the device was
already suspended when the system suspend began. The justification is
that a reset-resume is a kind of remote-wakeup event. Or to put it
another way, a device which needs a reset won't be able to generate
normal remote-wakeup signals, so it ought to be resumed immediately.)
Secondly, a dynamic power-management event may occur as a system
suspend is underway. The window for this is short, since system
suspends don't take long (a few seconds usually), but it can happen.
For example, a suspended device may send a remote-wakeup signal while
the system is suspending. The remote wakeup may succeed, which would
cause the system suspend to abort. If the remote wakeup doesn't
succeed, it may still remain active and thus cause the system to
resume as soon as the system suspend is complete. Or the remote
wakeup may fail and get lost. Which outcome occurs depends on timing
and on the hardware and firmware design.
More interestingly, a device might undergo a manual resume or
autoresume during system suspend. With current kernels this shouldn't
happen, because manual resumes must be initiated by userspace and
autoresumes happen in response to I/O requests, but all user processes
and I/O should be quiescent during a system suspend -- thanks to the
freezer. However there are plans to do away with the freezer, which
would mean these things would become possible. If and when this comes
about, the USB core will carefully arrange matters so that either type
of resume will block until the entire system has resumed.

the address space.
Note that you generally want to keep this value at or above 4k
(0x1000) as this will allow the kernel to capture NULL pointer
references.
Note that you need to keep this value above 4k (0x1000) as this
memory region is used to capture NULL pointer references as well
as some core kernel functions.
