This XBOX360 compatible gamepad uses the new product id 0x310a under the
8BitDo's vendor id 0x2dc8. The change was tested using the gamepad in a
wired and wireless dongle configuration.

The BSpec says that EN_L3_RW_CCS_CACHE_FLUSH must be toggled
on for manual global invalidation to take effect and actually flush
device cache, however this also turns on flushing for things like
pipecontrol, which occurs between submissions for compute/render. This
sounds like massive overkill for our needs, where we already have the
manual flushing on the display side with the global invalidation. Some
observations on BMG:
1. Disabling l2 caching for host writes and stubbing out the driver
global invalidation but keeping EN_L3_RW_CCS_CACHE_FLUSH enabled, has
no impact on wb-transient-vs-display IGT, which makes sense since the
pipecontrol is now flushing the device cache after the render copy.
Without EN_L3_RW_CCS_CACHE_FLUSH the test then fails, which is also
expected since device cache is now dirty and display engine can't see
the writes.
2. Disabling EN_L3_RW_CCS_CACHE_FLUSH, but keeping the driver global
invalidation also has no impact on wb-transient-vs-display. This
suggests that the global invalidation still works as expected and is
flushing the device cache without EN_L3_RW_CCS_CACHE_FLUSH turned on.
With that drop EN_L3_RW_CCS_CACHE_FLUSH. This helps some workloads since
we no longer flush the device cache between submissions as part of
pipecontrol.
Edit: We now also have clarification from HW side that BSpec was indeed
wrong here.

Starting with Xe2 the timestamp is a full 64 bit counter, contrary to
the 36 bit that was available before. Although 36 should be sufficient
for any reasonable delta calculation (for Xe2, of about 30min), it's
surprising to userspace to get something truncated. Also if the
timestamp being compared to is coming from the GPU and the application
is not careful enough to apply the width there, a delta calculation
would be wrong.
Extend it to full 64-bits starting with Xe2.
v2: Expand width=64 to media gt, as it's just a wrong tagging in the
spec - empirical tests show it goes beyond 36 bits and match the engines
for the main gt

Currently we can call fence_fini() twice if something goes wrong when
sending the GuC CT for the tlb request, since we signal the fence and
return an error, leading to the caller also calling fini() on the error
path in the case of stack version of the flow, which leads to an extra
rpm put() which might later cause device to enter suspend when it
shouldn't. It looks like we can just drop the fini() call since the
fence signaller side will already call this for us.
There are known mysterious splats with device going to sleep even with
an rpm ref, and this could be one candidate.

So rq_qos_wake_function() calls wake_up_process(data->task), which calls
try_to_wake_up(), which faults in raw_spin_lock_irqsave(&p->pi_lock).
p comes from data->task, and data comes from the waitqueue entry, which
is stored on the waiter's stack in rq_qos_wait(). Analyzing the core
dump with drgn, I found that the waiter had already woken up and moved
on to a completely unrelated code path, clobbering what was previously
data->task. Meanwhile, the waker was passing the clobbered garbage in
data->task to wake_up_process(), leading to the crash.
What's happening is that in between rq_qos_wake_function() deleting the
waitqueue entry and calling wake_up_process(), rq_qos_wait() is finding
that it already got a token and returning. The race looks like this:
rq_qos_wait() rq_qos_wake_function()
==============================================================
prepare_to_wait_exclusive()
data->got_token = true;
list_del_init(&curr->entry);
if (data.got_token)
break;
finish_wait(&rqw->wait, &data.wq);
^- returns immediately because
list_empty_careful(&wq_entry->entry)
is true
... return, go do something else ...
wake_up_process(data->task)
(NO LONGER VALID!)-^
Normally, finish_wait() is supposed to synchronize against the waker.
But, as noted above, it is returning immediately because the waitqueue
entry has already been removed from the waitqueue.
The bug is that rq_qos_wake_function() is accessing the waitqueue entry
AFTER deleting it. Note that autoremove_wake_function() wakes the waiter
and THEN deletes the waitqueue entry, which is the proper order.
Fix it by swapping the order. We also need to use
list_del_init_careful() to match the list_empty_careful() in
finish_wait().

Enable the Mali Valhall GPU on Genio 1200 EVK by providing regulator
supply settingsi to gpu and mfg1, and enable the GPU node.
In addition, set the GPU related regulator voltage range:
1. Set the recommended input voltage range of DVDD_GPU to (0.546V-0.787V),
based on Table 5-3 of MT8395 Application Processor Datasheet.
The regulator mt6315_7_vbuck1("Vgpu") connects to the DVDD_GPU input.
Note that the minimum voltage in SoC eFuse data, which is read by
MTK-SVS to adjust the regulator voltage, does not go below
the recommended operating voltage in the datasheet.
2. Set the input voltage of DVDD_SRAM_GPU, supplied by
mt6359_vsram_others_ldo_reg, to 0.75V, the recommended typical
operating voltage in MT8395 Application Processor Datasheet.
This patch is tested by enabling CONFIG_DRM_PANFROST and
on Genio 1200 EVK it probed with following dmesg:
```

Also initialize regs->psw.mask in perf_arch_fetch_caller_regs().
This way user_mode(regs) will return false, like it should.
It looks like all current users initialize regs to zero, so that this
doesn't fix a bug currently. However it is better to not rely on callers
to do this.

According to the VT220 specification the possible character combinations
sent on RETURN are only CR or CRLF [0].
The Return key sends either a CR character (0/13) or a CR
character (0/13) and an LF character (0/10), depending on the
set/reset state of line feed/new line mode (LNM).
The sclp/vt220 driver however uses LFCR. This can confuse tools, for
example the kunit runner.

On reboot the SCLP interface is deactivated through a reboot notifier.
This happens before other components using SCLP have the chance to run
their own reboot notifiers.
Two of those components are the SCLP console and tty drivers which try
to flush the last outstanding messages.
At that point the SCLP interface is already unusable and the messages
are discarded.
Execute sclp_deactivate() as late as possible to avoid this issue.
