The GuC communication protocol allows GuC to send NO_RESPONSE_RETRY
reply message to indicate that due to some interim condition it can
not handle incoming H2G request and the host shall resend it.
But in some cases, due to errors, this unsatisfied condition might
be final and this could lead to endless retries as it was recently
seen on the CI:
[drm] GT0: PF: VF1 FLR didn't finish in 5000 ms (-ETIMEDOUT)
[drm] GT0: PF: VF1 resource sanitizing failed (-ETIMEDOUT)
[drm] GT0: PF: VF1 FLR failed!
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
[drm:guc_ct_send_recv [xe]] GT0: H2G action 0x5503 retrying: reason 0x0
To avoid such dangerous loops allow only limited number of retries
(for now 50) and add some delays (n * 5ms) to slow down the rate of
resending this repeated request.

Unify on using poll_timeout_us() throughout instead of mixing with
readx_poll_timeout(). While the latter can be ever so slightly simpler,
they are both complicated enough that it's better to unify on one
approach only.
While at it, better separate the handling of error returns from
drm_dp_dpcd_readb() and the actual status byte. This is best achieved by
inlining the read_fec_detected_status() function, and switching to
drm_dp_dpcd_read_byte().

Prefer generic poll helpers over i915 custom helpers.
The "two tier" wait_for_us() + wait_for() combination appeared without
much explanation in commit 4e6c2d58ba86 ("drm/i915: Take forcewake once
for the entire GMBUS transaction"). Try to mimic roughly the same with
the generic helpers.
wait_for_us() with 10 us or shorter timeouts ends up in
_wait_for_atomic(). Thus use poll_timeout_us_atomic() for the first try,
with the same 2 us timeout and no sleep.
For the fallback, the functional change is losing the exponentially
growing sleep of wait_for(), which used to be 10, 20, 40, ..., 640, and
1280 us. Use an arbitrary constant 500 us sleep instead. The timeout
remains at 50 ms.

Our drm-based suballocator is implemented per-tile so it is better
to show its debug information also per-tile debugfs directory, not
under per-gt directory as it is done today.
To allow adding more per-tile attributes, prepare necessary helper
functions, like we already did for per-gt or per-uc attributes.

Use REG_BIT() instead of open coding the shift in the FW_BLC_SELF_*
macro definitions to avoid potentially typing them as 'int'.
For example, this happens when we pass them to _MASKED_BIT_ENABLE(),
because of the typeof() construct there. When we pass 1 << 15 (the
FW_BLC_SELF_EN macro), we get typeof(1 << 15), which is 'int'. Then
the value becomes negative (-2147450880) and we try to assign it to a
'u32'.
In practice this is not a problem though, because when we try to
assign -2147450880 to the u32, that becomes 0x80008000, which was the
intended result.

the code in ast_get_dram_info() to exactly this use case and move
it into the Gen's custom source file. Remove the field dram_type
from struct ast_device.
The AST_DRAM_ constants are also used in Gen4 POST helpers, but
independently from the dram_type field. No changes there.

Most of the information in the DRAM status output is irrelevant; some

The declaration of pointer crtc_state includes an assignment to
crtc_state. The double assignment of crtc_state is redundant and

copy_to_user() returns the number of bytes not copied on failure, not a
negative error code. Update the logic to return -EFAULT instead of the
number of bytes to correctly signal the error.

This reverts:
commit bead88002227 ("drm/nouveau: Remove waitque for sched teardown")
commit 5f46f5c7af8c ("drm/nouveau: Add new callback for scheduler teardown")
from the drm/sched teardown leak fix series:
https://lore.kernel.org/dri-devel/20250710125412.128476-2-phasta@kernel.org/
The aforementioned series removed a blocking waitqueue from
nouveau_sched_fini(). It was mistakenly assumed that this waitqueue only
prevents jobs from leaking, which the series fixed.
The waitqueue, however, also guarantees that all VM_BIND related jobs
are finished in order, cleaning up mappings in the GPU's MMU. These jobs
must be executed sequentially. Without the waitqueue, this is no longer
guaranteed, because entity and scheduler teardown can race with each
other.
Revert all patches related to the waitqueue removal.
