[ Upstream commit 67dffd3db98570af8ff54c934f7d14664c0d182a ]
Function hinic_get_stats64() will do two operations:
1. reads stats from every hinic_rxq/txq and accumulates them
2. calls hinic_rxq/txq_clean_stats() to clean every rxq/txq's stats
For hinic_get_stats64(), it could get right data, because it sums all
data to nic_dev->rx_stats/tx_stats.
But it is wrong for get_drv_queue_stats(), this function will read
hinic_rxq's stats, which have been cleared to zero by hinic_get_stats64().
I have observed hinic's cleanup operation by using such command:
> watch -n 1 "cat ethtool -S eth4 | tail -40"

To solve this problem, we just keep every queue's total stats in their own
queue (aka hinic_{rxq|txq}), and simply sum all per-queue stats every time
calling hinic_get_stats64().
With that solution, there is no need to clean per-queue stats now,
and there is no need to maintain global hinic_dev.{tx|rx}_stats, too.

'vlan_bitmap' is a bitmap and is used as such. So allocate it with
devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID).
This avoids the need of the VLAN_BITMAP_SIZE macro which:
- needlessly has a 'nic_dev' parameter
- should be "long" (and not byte) aligned, so that the bitmap semantic
is respected
This is in fact not an issue because VLAN_N_VID is 4096 at the time
being, but devm_bitmap_zalloc() is less verbose and easier to understand.

[ Upstream commit 55a515b1f5a97df5704a1788fe97a4a740be2b9e ]
Currently, sending a packet into a time gate too small for it (or always
closed) causes the queue system to hold the frame forever. Even worse,
this frame isn't subject to aging either, because for that to happen, it
needs to be scheduled for transmission in the first place. But the frame
will consume buffer memory and frame references while it is forever held
in the queue system.
Before commit a4ae997adcbd ("net: mscc: ocelot: initialize watermarks to
sane defaults"), this behavior was somewhat subtle, as the switch had a
more intricately tuned default watermark configuration out of reset,
which did not allow any single port and tc to consume the entire switch
buffer space. Nonetheless, the held frames are still there, and they
reduce the total backplane capacity of the switch.
However, after the aforementioned commit, the behavior can be very
clearly seen, since we deliberately allow each {port, tc} to consume the
entire shared buffer of the switch minus the reservations (and we
disable all reservations by default). That is to say, we allow a
permanently closed tc-taprio gate to hang the entire switch.
A careful inspection of the documentation shows that the QSYS:Q_MAX_SDU
per-port-tc registers serve 2 purposes: one is for guard band calculation
(when zero, this falls back to QSYS:PORT_MAX_SDU), and the other is to
enable oversized frame dropping (when non-zero).
Currently the QSYS:Q_MAX_SDU registers are all zero, so oversized frame
dropping is disabled. The goal of the change is to enable it seamlessly.
For that, we need to hook into the MTU change, tc-taprio change, and
port link speed change procedures, since we depend on these variables.
Frames are not dropped on egress due to a queue system oversize
condition, instead that egress port is simply excluded from the mask of
valid destination ports for the packet. If there are no destination
ports at all, the ingress counter that increments is the generic
"drop_tail" in ethtool -S.
The issue exists in various forms since the tc-taprio offload was introduced.

When adjusting the PTP clock, the base time of the TAS configuration
will become unreliable. We need reset the TAS configuration by using a
new base time.
For example, if the driver gets a base time 0 of Qbv configuration from
user, and current time is 20000. The driver will set the TAS base time
to be 20000. After the PTP clock adjustment, the current time becomes
10000. If the TAS base time is still 20000, it will be a future time,
and TAS entry list will stop running. Another example, if the current
time becomes to be 10000000 after PTP clock adjust, a large time offset
can cause the hardware to hang.
This patch introduces a tas_clock_adjust() function to reset the TAS
module by using a new base time after the PTP clock adjustment. This can
avoid issues above.
Due to PTP clock adjustment can occur at any time, it may conflict with
the TAS configuration. We introduce a new TAS lock to serialize the
access to the TAS registers.

Currently, xsk_socket__delete frees BPF resources regardless of ctx
refcount. Xdpxceiver has a test to verify whether underlying BPF
resources would not be wiped out after closing XSK socket that was
bound to interface with other active sockets. From library's xsk part
perspective it also means that the internal xsk context is shared and
its refcount is bumped accordingly.
After a switch to loading XDP prog based on previously opened XSK
socket, mentioned xdpxceiver test fails with:
not ok 16 [xdpxceiver.c:swap_xsk_resources:1334]: ERROR: 9/"Bad file descriptor
which means that in swap_xsk_resources(), xsk_socket__delete() released
xskmap which in turn caused a failure of xsk_socket__update_xskmap().
To fix this, when deleting socket, decrement ctx refcount before
releasing BPF resources and do so only when refcount dropped to 0 which
means there are no more active sockets for this ctx so BPF resources can
be freed safely.

Whenever the maximum BPC is changed, vc4_hdmi_encoder_compute_config()
might pick up a different BPC or format depending on the display
capabilities.
That change will have a number of side effects, including the clock
rates and whether the scrambling is enabled.
However, only drm_crtc_state.connectors_changed will be set to true,
since that properly only affects the connector.
This means that while drm_atomic_crtc_needs_modeset() will return true,
and thus drm_atomic_helper_commit_modeset_enables() will call our
encoder atomic_enable() hook, mode_changed will be false.
So crtc_set_mode() will not call our encoder .atomic_mode_set() hook. We
use this hook in vc4 to set the vc4_hdmi_connector_state.output_bpc (and
output_format), and will then reuse the value in .atomic_enable() to select
whether or not scrambling should be enabled.
However, since our clock rate is pre-computed during .atomic_check(), we
end up with the clocks properly configured, but the scrambling disabled,
leading to a blank screen.
Let's set mode_changed to true in our HDMI driver to force the update of

The BCM2835-37 found in the RaspberryPi 0 to 3 have a power domain
attached to the HDMI block, handled in Linux through runtime_pm.
That power domain is shared with the VEC block, so even if we put our
runtime_pm reference in the HDMI driver it would keep being on. If the
VEC is disabled though, the power domain would be disabled and we would
lose any initialization done in our bind implementation.
That initialization involves calling the reset function and initializing
the CEC registers.
Let's move the initialization to our runtime_resume implementation so
that we initialize everything properly if we ever need to.

If the controller isn't clocked or its domain powered up, the register
accesses will either stall the CPU or return garbage, respectively.
Thus, we had a warning in our register access function to complain when
that kind of risky accesses were performed.
In order to check the runtime_pm power state, we were using
pm_runtime_active(), but it turns out that it will become active only
once the runtime_resume hook has been executed.
This prevents us from doing any WARN-free register access in our
runtime_resume() implementation, while this is valid.
Let's switch to pm_runtime_status_suspended() instead.

aborted without handling the "error" case, and could end up with a clock

The integer divider from parent PLL to DSI clock is also capable of
going up to /255, not just /7 that the driver was trying. This allows
for slower link frequencies on the DSI bus where the resolution permits.

The core clock computation takes into account both the load due to the
input (ie, planes) and its output (ie, encoders).
However, while the input load needs to consider all the planes, and thus
sum all of their associated loads, the output happens mostly in
parallel.
Therefore, we need to consider only the maximum of all the output loads,
and not the sum like we were doing. This resulted in a clock rate way
too high which could be discarded for being too high by the clock
framework.
Since recent changes, the clock framework will even downright reject it,
leading to a core clock being too low for its current needs.

Error return values are supposed to be negative in hdpvr_read. Most
error returns are currently handled via an unsigned integer "ret". When
setting a negative error value to "ret", the value actually becomes a
large positive value, because "ret" is unsigned. Later on, the "ret"
value is returned. But as ssize_t is a 64-bit signed number, the error
return value stays a large positive integer instead of a negative
integer. This can cause an error value to be interpreted as the read
size, which can cause a buffer overread for applications relying on the
returned size.
