Merge branch 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Pull the MCA deletion branch from Paul Gortmaker:
"It was good that we could support MCA machines back in the day, but
realistically, nobody is using them anymore. They were mostly limited
to 386-sx 16MHz CPU and some 486 class machines and never more than
64MB of RAM. Even the enthusiast hobbyist community seems to have
dried up close to ten years ago, based on what you can find searching
various websites dedicated to the relatively short lived hardware.
So lets remove the support relating to CONFIG_MCA. There is no point
carrying this forward, wasting cycles doing routine maintenance on it;
wasting allyesconfig build time on validating it, wasting I/O on git
grep'ping over it, and so on."
Let's see if anybody screams. It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines. So in *theory*
there may be users out there.
But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.
So we could bring it back. But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that. And David already took the patch to delete
all the networking driver code (commit a5e371f61a: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").
* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
MCA: delete all remaining traces of microchannel bus support.
scsi: delete the MCA specific drivers and driver code
serial: delete the MCA specific 8250 support.
arm: remove ability to select CONFIG_MCA

The MCA bus functions provide a generalised interface to find MCA

The basic interface to the MCA bus devices is the slot. Each slot

is numbered and virtual slot numbers are assigned to the internal

devices. Using a pci_dev as other busses do does not really make

sense in the MCA context as the MCA bus resources require card

specific interpretation.

i386 Micro Channel Architecture Support
|
||||
=======================================
|
||||
|
||||
MCA support is enabled using the CONFIG_MCA define. A machine with a MCA
|
||||
bus will have the kernel variable MCA_bus set, assuming the BIOS feature
|
||||
bits are set properly (see arch/i386/boot/setup.S for information on
|
||||
how this detection is done).
|
||||
|
||||
Adapter Detection
|
||||
=================
|
||||
|
||||
The ideal MCA adapter detection is done through the use of the
|
||||
Programmable Option Select registers. Generic functions for doing
|
||||
this have been added in include/linux/mca.h and arch/x86/kernel/mca_32.c.
|
||||
Everything needed to detect adapters and read (and write) configuration
|
||||
information is there. A number of MCA-specific drivers already use
|
||||
this. The typical probe code looks like the following:
|
||||
|
||||
#include <linux/mca.h>
|
||||
|
||||
unsigned char pos2, pos3, pos4, pos5;
|
||||
struct net_device* dev;
|
||||
int slot;
|
||||
|
||||
if( MCA_bus ) {
|
||||
slot = mca_find_adapter( ADAPTER_ID, 0 );
|
||||
if( slot == MCA_NOTFOUND ) {
|
||||
return -ENODEV;
|
||||
}
|
||||
/* optional - see below */
|
||||
mca_set_adapter_name( slot, "adapter name & description" );
|
||||
mca_set_adapter_procfn( slot, dev_getinfo, dev );
|
||||
|
||||
/* read the POS registers. Most devices only use 2 and 3 */
|
||||
pos2 = mca_read_stored_pos( slot, 2 );
|
||||
pos3 = mca_read_stored_pos( slot, 3 );
|
||||
pos4 = mca_read_stored_pos( slot, 4 );
|
||||
pos5 = mca_read_stored_pos( slot, 5 );
|
||||
} else {
|
||||
return -ENODEV;
|
||||
}
|
||||
|
||||
/* extract configuration from pos[2345] and set everything up */
|
||||
|
||||
Loadable modules should modify this to test that the specified IRQ and
|
||||
IO ports (plus whatever other stuff) match. See 3c523.c for example
|
||||
code (actually, smc-mca.c has a slightly more complex example that can
|
||||
handle a list of adapter ids).
|
||||
|
||||
Keep in mind that devices should never directly access the POS registers
|
||||
(via inb(), outb(), etc). While it's generally safe, there is a small
|
||||
potential for blowing up hardware when it's done at the wrong time.
|
||||
Furthermore, accessing a POS register disables a device temporarily.
|
||||
This is usually okay during startup, but do _you_ want to rely on it?
|
||||
During initial configuration, mca_init() reads all the POS registers
|
||||
into memory. mca_read_stored_pos() accesses that data. mca_read_pos()
|
||||
and mca_write_pos() are also available for (safer) direct POS access,
|
||||
but their use is _highly_ discouraged. mca_write_pos() is particularly
|
||||
dangerous, as it is possible for adapters to be put in inconsistent
|
||||
states (i.e. sharing IO address, etc) and may result in crashes, toasted
|
||||
hardware, and blindness.
|
||||
|
||||
User level drivers (such as the AGX X server) can use /proc/mca/pos to
|
||||
find adapters (see below).
|
||||
|
||||
Some MCA adapters can also be detected via the usual ISA-style device
|
||||
probing (many SCSI adapters, for example). This sort of thing is highly
|
||||
discouraged. Perfectly good information is available telling you what's
|
||||
there, so there's no excuse for messing with random IO ports. However,
|
||||
we MCA people still appreciate any ISA-style driver that will work with
|
||||
our hardware. You take what you can get...
|
||||
|
||||
Level-Triggered Interrupts
|
||||
==========================
|
||||
|
||||
Because MCA uses level-triggered interrupts, a few problems arise with
|
||||
what might best be described as the ISA mindset and its effects on
|
||||
drivers. These sorts of problems are expected to become less common as
|
||||
more people use shared IRQs on PCI machines.
|
||||
|
||||
In general, an interrupt must be acknowledged not only at the ICU (which
|
||||
is done automagically by the kernel), but at the device level. In
|
||||
particular, IRQ 0 must be reset after a timer interrupt (now done in
|
||||
arch/x86/kernel/time.c) or the first timer interrupt hangs the system.
|
||||
There were also problems with the 1.3.x floppy drivers, but that seems
|
||||
to have been fixed.
|
||||
|
||||
IRQs are also shareable, and most MCA-specific devices should be coded
|
||||
with shared IRQs in mind.
|
||||
|
||||
/proc/mca
|
||||
=========
|
||||
|
||||
/proc/mca is a directory containing various files for adapters and
|
||||
other stuff.
|
||||
|
||||
/proc/mca/pos Straight listing of POS registers
|
||||
/proc/mca/slot[1-8] Information on adapter in specific slot
|
||||
/proc/mca/video Same for integrated video
|
||||
/proc/mca/scsi Same for integrated SCSI
|
||||
/proc/mca/machine Machine information
|
||||
|
||||
See Appendix A for a sample.
|
||||
|
||||
Device drivers can easily add their own information function for
|
||||
specific slots (including integrated ones) via the
|
||||
mca_set_adapter_procfn() call. Drivers that support this are ESDI, IBM
|
||||
SCSI, and 3c523. If a device is also a module, make sure that the proc
|
||||
function is removed in the module cleanup. This will require storing
|
||||
the slot information in a private structure somewhere. See the 3c523
|
||||
driver for details.
|
||||
|
||||
Your typical proc function will look something like this:
|
||||
|
||||
static int
|
||||
dev_getinfo( char* buf, int slot, void* d ) {
|
||||
struct net_device* dev = (struct net_device*) d;
|
||||
int len = 0;
|
||||
|
||||
len += sprintf( buf+len, "Device: %s\n", dev->name );
|
||||
len += sprintf( buf+len, "IRQ: %d\n", dev->irq );
|
||||
len += sprintf( buf+len, "IO Port: %#lx-%#lx\n", ... );
|
||||
...
|
||||
|
||||
return len;
|
||||
}
|
||||
|
||||
Some of the standard MCA information will already be printed, so don't
|
||||
bother repeating it. Don't try putting in more than 3K of information.
|
||||
|
||||
Enable this function with:
|
||||
mca_set_adapter_procfn( slot, dev_getinfo, dev );
|
||||
|
||||
Disable it with:
|
||||
mca_set_adapter_procfn( slot, NULL, NULL );
|
||||
|
||||
It is also recommended that, even if you don't write a proc function, to
|
||||
set the name of the adapter (i.e. "PS/2 ESDI Controller") via
|
||||
mca_set_adapter_name( int slot, char* name ).
|
||||
|
||||
MCA Device Drivers
|
||||
==================
|
||||
|
||||
Currently, there are a number of MCA-specific device drivers.
|
||||
|
||||
1) PS/2 SCSI
|
||||
drivers/scsi/ibmmca.c
|
||||
drivers/scsi/ibmmca.h
|
||||
The driver for the IBM SCSI subsystem. Includes both integrated
|
||||
controllers and adapter cards. May require command-line arg
|
||||
"ibmmcascsi=io_port" to force detection of an adapter. If you have a
|
||||
machine with a front-panel display (i.e. model 95), you can use
|
||||
"ibmmcascsi=display" to enable a drive activity indicator.
|
||||
|
||||
2) 3c523
|
||||
drivers/net/3c523.c
|
||||
drivers/net/3c523.h
|
||||
3Com 3c523 Etherlink/MC ethernet driver.
|
||||
|
||||
3) SMC Ultra/MCA and IBM Adapter/A
|
||||
drivers/net/smc-mca.c
|
||||
drivers/net/smc-mca.h
|
||||
Driver for the MCA version of the SMC Ultra and various other
|
||||
OEM'ed and work-alike cards (Elite, Adapter/A, etc).
|
||||
|
||||
4) NE/2
|
||||
driver/net/ne2.c
|
||||
driver/net/ne2.h
|
||||
The NE/2 is the MCA version of the NE2000. This may not work
|
||||
with clones that have a different adapter id than the original
|
||||
NE/2.
|
||||
|
||||
5) Future Domain MCS-600/700, OEM'd IBM Fast SCSI Adapter/A and
|
||||
Reply Sound Blaster/SCSI (SCSI part)
|
||||
Better support for these cards than the driver for ISA.
|
||||
Supports multiple cards with IRQ sharing.
|
||||
|
||||
Also added boot time option of scsi-probe, which can do reordering of
|
||||
SCSI host adapters. This will direct the kernel on the order which
|
||||
SCSI adapter should be detected. Example:
|
||||
scsi-probe=ibmmca,fd_mcs,adaptec1542,buslogic
|
||||
|
||||
The serial drivers were modified to support the extended IO port range
|
||||
of the typical MCA system (also #ifdef CONFIG_MCA).
|
||||
|
||||
The following devices work with existing drivers:
|
||||
1) Token-ring
|
||||
2) Future Domain SCSI (MCS-600, MCS-700, not MCS-350, OEM'ed IBM SCSI)
|
||||
3) Adaptec 1640 SCSI (using the aha1542 driver)
|
||||
4) Bustek/Buslogic SCSI (various)
|
||||
5) Probably all Arcnet cards.
|
||||
6) Some, possibly all, MCA IDE controllers.
|
||||
7) 3Com 3c529 (MCA version of 3c509) (patched)
|
||||
|
||||
8) Intel EtherExpressMC (patched version)
|
||||
You need to have CONFIG_MCA defined to have EtherExpressMC support.
|
||||
9) Reply Sound Blaster/SCSI (SB part) (patched version)
|
||||
|
||||
Bugs & Other Weirdness
|
||||
======================
|
||||
|
||||
NMIs tend to occur with MCA machines because of various hardware
|
||||
weirdness, bus timeouts, and many other non-critical things. Some basic
|
||||
code to handle them (inspired by the NetBSD MCA code) has been added to
|
||||
detect the guilty device, but it's pretty incomplete. If NMIs are a
|
||||
persistent problem (on some model 70 or 80s, they occur every couple
|
||||
shell commands), the CONFIG_IGNORE_NMI flag will take care of that.
|
||||
|
||||
Various Pentium machines have had serious problems with the FPU test in
|
||||
bugs.h. Basically, the machine hangs after the HLT test. This occurs,
|
||||
as far as we know, on the Pentium-equipped 85s, 95s, and some PC Servers.
|
||||
The PCI/MCA PC 750s are fine as far as I can tell. The ``mca-pentium''
|
||||
boot-prompt flag will disable the FPU bug check if this is a problem
|
||||
with your machine.
|
||||
|
||||
The model 80 has a raft of problems that are just too weird and unique
|
||||
to get into here. Some people have no trouble while others have nothing
|
||||
but problems. I'd suspect some problems are related to the age of the
|
||||
average 80 and accompanying hardware deterioration, although others
|
||||
are definitely design problems with the hardware. Among the problems
|
||||
include SCSI controller problems, ESDI controller problems, and serious
|
||||
screw-ups in the floppy controller. Oh, and the parallel port is also
|
||||
pretty flaky. There were about 5 or 6 different model 80 motherboards
|
||||
produced to fix various obscure problems. As far as I know, it's pretty
|
||||
much impossible to tell which bugs a particular model 80 has (other than
|
||||
triggering them, that is).
|
||||
|
||||
Drivers are required for some MCA memory adapters. If you're suddenly
|
||||
short a few megs of RAM, this might be the reason. The (I think) Enhanced
|
||||
Memory Adapter commonly found on the model 70 is one. There's a very
|
||||
alpha driver floating around, but it's pretty ugly (disassembled from
|
||||
the DOS driver, actually). See the MCA Linux web page (URL below)
|
||||
for more current memory info.
|
||||
|
||||
The Thinkpad 700 and 720 will work, but various components are either
|
||||
non-functional, flaky, or we don't know anything about them. The
|
||||
graphics controller is supposed to be some WD, but we can't get things
|
||||
working properly. The PCMCIA slots don't seem to work. Ditto for APM.
|
||||
The serial ports work, but detection seems to be flaky.

If the adapter isn't found during boot (a common problem for models
|
||||
56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
|
||||
option, where <pun> is the id of the SCSI subsystem (usually 7, but
|
||||
if that doesn't work check your reference diskette). Owners of
|
||||
model 95 with a LED-matrix-display can in addition activate some
|
||||
activity info like under OS/2, but more informative, by setting
|
||||
'ibmmcascsi=display' as an additional kernel parameter. Try "man
|
||||
bootparam" or see the documentation of your boot loader about how to
|
||||
pass options to the kernel.
|
||||
|
||||
To compile this driver as a module, choose M here: the
|
||||
module will be called ibmmca.
|
||||
|
||||
config IBMMCA_SCSI_ORDER_STANDARD

bool "Standard SCSI-order"

||||

|
||||
---help---
|
||||
In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
|
||||
are assigned to the drive letters, starting with the lowest SCSI-id
|
||||
(physical number -- pun) to be drive C:, as seen from DOS and
|
||||
similar operating systems. When looking into papers describing the
|
||||
ANSI-SCSI-standard, this assignment of drives appears to be wrong.
|
||||
The SCSI-standard follows a hardware-hierarchy which says that id 7
|
||||
has the highest priority and id 0 the lowest. Therefore, the host
|
||||
adapters are still today everywhere placed as SCSI-id 7 by default.
|
||||
In the SCSI-standard, the drive letters express the priority of the
|
||||
disk. C: should be the hard disk, or a partition on it, with the
|
||||
highest priority. This must therefore be the disk with the highest
|
||||
SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
|
||||
original definition of the SCSI-standard as also industrial- and
|
||||
process-control-machines, like VME-CPUs running under realtime-OSes
|
||||
(e.g. LynxOS, OS9) do.
|
||||
|
||||
If you like to run Linux on your MCA-machine with the same
|
||||
assignment of hard disks as seen from e.g. DOS or OS/2 on your
|
||||
machine, which is in addition conformant to the SCSI-standard, you
|
||||
must say Y here. This is also necessary for MCA-Linux users who want
|
||||
to keep downward compatibility to older releases of the
|
||||
IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
|
||||
June 1997).
|
||||
|
||||
If you like to have the lowest SCSI-id assigned as drive C:, as
|
||||
modern SCSI-BIOSes do, which does not conform to the standard, but
|
||||
is widespread and common in the PC-world of today, you must say N
|
||||
here. If unsure, say Y.
|
||||
|
||||
config IBMMCA_SCSI_DEV_RESET
|
||||
bool "Reset SCSI-devices at boottime"
|
||||
depends on SCSI_IBMMCA
|
||||
---help---
|
||||
By default, SCSI-devices are reset when the machine is powered on.
|
||||
However, some devices exist, like special-control-devices,
|
||||
SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
|
||||
not reset when switched on. If you say Y here, each device connected
|
||||
to your SCSI-bus will be issued a reset-command after it has been
|
||||
probed, while the kernel is booting. This may cause problems with
|
||||
more modern devices, like hard disks, which do not appreciate these
|
||||
reset commands, and can cause your system to hang. So say Y only if
|
||||
you know that one of your older devices needs it; N is the safe
|
||||
answer.
