1ba6113a90a0 removed a lot of the kernel GPU channel, but method 0x128
was important as otherwise the GPU spams us with `CACHE_ERROR` messages.
We use the blit subchannel inside our vblank handling, so we should keep
at least this part.
v2: Only do it for NV11+ GPUs

The simple_write_to_buffer() function is designed to handle partial
writes. It returns negatives on error, otherwise it returns the number
of bytes that were able to be copied. This code doesn't check the
return properly. We only know that the first byte is written, the rest
of the buffer might be uninitialized.
There is no need to use the simple_write_to_buffer() function.
Partial writes are prohibited by the "if (*ppos != 0)" check at the
start of the function. Just use memdup_user() and copy the whole
buffer.

The soundwire subsystem uses two completion structures that allow
drivers to wait for soundwire device to become enumerated on the bus and
initialised by their drivers, respectively.
The code implementing the signalling is currently broken as it does not
signal all current and future waiters and also uses the wrong
reinitialisation function, which can potentially lead to memory
corruption if there are still waiters on the queue.
Not signalling future waiters specifically breaks sound card probe
deferrals as codec drivers can not tell that the soundwire device is
already attached when being reprobed. Some codec runtime PM
implementations suffer from similar problems as waiting for enumeration
during resume can also timeout despite the device already having been
enumerated.

The driver is not enabling the ref clock, which thus gets disabled by
the clk_disable_unused() initcall. This leads to the dwc3 controller
failing to initialize if probed after clk_disable_unused() is called,
for instance when the driver is built as a module.
To fix this, switch to the clk_bulk API to handle both cfg_ahb and ref
clocks at the proper places.
Note that the cfg_ahb clock is currently not used by any device tree
instantiation of the PHY. Work needs to be done separately to fix this.

In the dwc3 core, both system and runtime suspend end up calling
dwc3_suspend_common(). From there, what happens for the PHYs depends on
the USB mode and whether the controller is entering system or runtime
suspend.
HOST mode:
(1) system suspend on a non-wakeup-capable controller
The [1] if branch is taken. dwc3_core_exit() is called, which ends up
calling phy_power_off() and phy_exit(). Those two functions decrease the
PM runtime count at some point, so they will trigger the PHY runtime
sleep (assuming the count is right).
(2) runtime suspend / system suspend on a wakeup-capable controller
The [1] branch is not taken. dwc3_suspend_common() calls
phy_pm_runtime_put_sync(). Assuming the ref count is right, the PHY
runtime suspend op is called.
DEVICE mode:
dwc3_core_exit() is called on both runtime and system sleep
unless the controller is already runtime suspended.
OTG mode:
(1) system suspend : dwc3_core_exit() is called
(2) runtime suspend : do nothing
In host mode, the code seems to make a distinction between 1) runtime
sleep / system sleep for wakeup-capable controller, and 2) system sleep
for non-wakeup-capable controller, where phy_power_off() and phy_exit()
are only called for the latter. This suggests the PHY is not supposed to
be in a fully powered-off state for runtime sleep and system sleep for
wakeup-capable controller.
Moreover, downstream, cfg_ahb_clk only gets disabled for system suspend.
The clocks are disabled by phy->set_suspend() [2] which is only called
in the system sleep path through dwc3_core_exit() [3].
With that in mind, don't disable the clocks during the femto PHY runtime
suspend callback. The clocks will only be disabled during system suspend
for non-wakeup-capable controllers, through dwc3_core_exit().

If any error handling that disables the controller fails to queue the
reset work, like if the state changed to disconnected inbetween, then
the failed teardown needs to unquiesce the queues since it's no longer
paired with reset_work. Just make sure that the controller can be put
into a resetting state prior to starting the disable so that no other
handling can change the queue states while recovery is happening.

Since commit 096b52fd2bb4 ("perf: RISC-V: throttle perf events") the
perf_sample_event_took() function was added to report time spent in
overflow interrupts. If the interrupt takes too long, the perf framework
will lower the sysctl_perf_event_sample_rate and max_samples_per_tick.
When hwc->interrupts is larger than max_samples_per_tick, the
hwc->interrupts will be set to MAX_INTERRUPTS, and events will be
throttled within the __perf_event_account_interrupt() function.
However, the RISC-V PMU driver doesn't call riscv_pmu_stop() to update the
PERF_HES_STOPPED flag after perf_event_overflow() in pmu_sbi_ovf_handler()
function to avoid throttling. When the perf framework unthrottled the event
in the timer interrupt handler, it triggers riscv_pmu_start() function
and causes a WARN_ON_ONCE() warning, as shown below:

When allocating the 2D array for handling IRQ type registers in
regmap_add_irq_chip_fwnode(), the intent is to allocate a matrix
with num_config_bases rows and num_config_regs columns.
This is currently handled by allocating a buffer to hold a pointer for
each row (i.e. num_config_bases). After that, the logic attempts to
allocate the memory required to hold the register configuration for
each row. However, instead of doing this allocation for each row
(i.e. num_config_bases allocations), the logic erroneously does this
allocation num_config_regs number of times.
This scenario can lead to out-of-bounds accesses when num_config_regs
is greater than num_config_bases. Fix this by updating the terminating
condition of the loop that allocates the memory for holding the register
configuration to allocate memory only for each row in the matrix.
Amit Pundir reported a crash that was occurring on his db845c device
due to memory corruption (see "Closes" tag for Amit's report). The KASAN
report below helped narrow it down to this issue:

igc: Fix corner cases for TSN offload
Florian Kauer says:
The igc driver supports several different offloading capabilities
relevant in the TSN context. Recent patches in this area introduced
regressions for certain corner cases that are fixed in this series.
Each of the patches (except the first one) addresses a different
regression that can be separately reproduced. Still, they have
overlapping code changes so they should not be separately applied.
Especially #4 and #6 address the same observation,
but both need to be applied to avoid TX hang occurrences in
the scenario described in the patches.

This is equivalent to 'gen2', and it was always confusing to have
two identical config entries. The split config patch actually had
been originally developed after removing 'use_tfh" and didn't add
the use_tfh in the new configs as they'd later been copied to the
new files. Thus the easiest way to fix the init crash here now is
to just remove use_tfh (which is erroneously unset in most of the
configs now) and use 'gen2' in the code instead.
There's possibly still an unwind error in iwl_txq_gen2_init() as
it crashes if TXQ 0 fails to initialize, but we can deal with it
later since the original failure is due to the use_tfh confusion.

Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"),
as spotted by Frédéric Bonnard, the historical "of-display" device is
gone: the updated logic creates "of-display.0" instead, then as many
"of-display.N" as required.
This means that offb no longer finds the expected device, which prevents
the Debian Installer from setting up its interface, at least on ppc64el.
Fix this by keeping "of-display" for the first device and "of-display.N"
for subsequent devices.

In response to a disk I/O request, Hyper-V has been observed to return SRB
status value 0x30. This indicates the request was not processed by Hyper-V
because low memory conditions on the host caused an internal error. The
0x30 status is not recognized by storvsc, so the I/O operation is not
flagged as an error. The request is treated as if it completed normally but
with zero data transferred, causing a flood of retries.
Add a definition for this SRB status value and handle it like other error
statuses from the Hyper-V host.

Generate a hotplug event after registering a client to allow the
client to configure its display. Remove the hotplug calls from the
existing clients for fbdev emulation. This change fixes a concurrency
bug between registering a client and receiving events from the DRM
core. The bug is present in the fbdev emulation of all drivers.
The fbdev emulation currently generates a hotplug event before
registering the client to the device. For each new output, the DRM
core sends an additional hotplug event to each registered client.
If the DRM core detects first output between sending the artificial
hotplug and registering the device, the output's hotplug event gets
lost. If this is the first output, the fbdev console display remains
dark. This has been observed with amdgpu and fbdev-generic.
Fix this by adding hotplug generation directly to the client's
register helper drm_client_register(). Registering the client and
receiving events are serialized by struct drm_device.clientlist_mutex.
So an output is either configured by the initial hotplug event, or
the client has already been registered.
The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper:
generic: Call drm_client_add() after setup is done"), in which adding
a client and receiving a hotplug event switched order. It was hidden,
as most hardware and drivers have at least on static output configured.
Other drivers didn't use the internal DRM client or still had struct
drm_mode_config_funcs.output_poll_changed set. That callback handled
hotplug events as well. After not setting the callback in amdgpu in
commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct
drm_driver.output_poll_changed"), amdgpu did not show a framebuffer
console if output events got lost. The bug got copy-pasted from
fbdev-generic into the other fbdev emulation.

that of the Lenovo issues with NVME resume. Lucienne was released in
a similar timeframe as the Renoir / Cezanne Lenovo laptops and they
may have similar BIOS code.
Applying the same quirk to this system allows the system to work with
IOMMU enabled and s2idle resume to work.
