The helper drm_simple_encoder_init() is a trivial helper around
drm_encoder_init() and therefore deprecated. Open-code the function

Some functions used by the HVS->PV muxing tests can return with EDEADLK,
meaning the entire sequence should be restarted. It's not a fatal error
and we should treat it as a recoverable error, and recover, instead of
failing the test like we currently do.

The vc4-pv-muxing-combinations and vc5-pv-muxing-combinations test
suites use a common test init function which, in part, allocates the
drm atomic state the test will use.
That allocation relies on drm_kunit_helper_atomic_state_alloc(), and
thus requires a struct drm_modeset_acquire_ctx. This context will then
be stored in the allocated state->acquire_ctx field.
However, the context is local to the test init function, and is cleared
as soon as drm_kunit_helper_atomic_state_alloc() is done. We thus end up
with an dangling pointer to a cleared context in state->acquire_ctx for
our test to consumes.
We should really allocate the context and the state in the test
functions, so we can also control when we're done with it.

The vc4_mock_atomic_add_output() and vc4_mock_atomic_del_output() assert
that the functions they are calling didn't fail. Since some of them can
return EDEADLK, we can't properly deal with it.
Since both functions are expected to return an int, and all caller check
the return value, let's just properly propagate the errors when they
occur.

Some SKUs of Xe2_HPD platforms (such as BMG) have GDDR memory type
with ECC enabled. We need to identify this scenario and add a new
case in xelpdp_get_dram_info() to handle it. In addition, the
derating value needs to be adjusted accordingly to compensate for
the limited bandwidth.

According to the DP spec TPS4 is mandatory for HBR3. We have
however seen some broken eDP sinks that violate this and
declare support for HBR3 without TPS4 support.
At least in the case of the icl Dell XPS 13 7390 this results
in an unstable output.
Reject HBR3 when TPS4 supports is unavailable on the sink.

Initializing const char opregion_signature[16] = OPREGION_SIGNATURE
(which is "IntelGraphicsMem") drops the NUL termination of the
string. This is intentional, but the compiler doesn't know this.
Switch to initializing header->signature directly from the string
litaral, with sizeof destination rather than source. We don't treat the
signature as a string other than for initialization; it's really just a
blob of binary data.
Add a static assert for good measure to cross-check the sizes.

To address this, disable Render Power-Gating (RPG) during live self-tests

The RZ/G2L driver utilises the VSPD to read data from input sources.
The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPD which prevents additional formats from being used for
display planes.
The supported display plane formats are mapped in rzg2l_du_vsp_formats[].
Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.
The RPF module on VSPD supports various format conversion and send the
image data to BRS(Blend ROP Sub Unit) for further processing.

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

When a vm runs under fault mode, if scratch page is enabled, we need
to clear the scratch page mapping on vm_bind for the vm_bind address
range. Under fault mode, we depend on recoverable page fault to
establish mapping in page table. If scratch page is not cleared, GPU
access of address won't cause page fault because it always hits the
existing scratch page mapping.
When vm_bind with IMMEDIATE flag, there is no need of clearing as
immediate bind can overwrite the scratch page mapping.
So far only is xe2 and xe3 products are allowed to enable scratch page
under fault mode. On other platform we don't allow scratch page under
fault mode, so no need of such clearing.
v2: Rework vm_bind pipeline to clear scratch page mapping. This is similar
to a map operation, with the exception that PTEs are cleared instead of
pointing to valid physical pages. (Matt, Thomas)

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.
Conversion was done with coccinelle plus manual fixups where necessary.

intel_compute_sagv_mask() has become pointless. Just inline

If there are no changes to intel_crtc_can_enable_sagv() there
is no need to do all the sagv bw_state recomputation.
The only slight caveat here is hw state takeover where we
initially disable SAGV, and want it to get re-enabled once
we've determined that it's safe to do so. That can now be
achieved by having intel_crtc_can_enable_sagv() reject SAGV
as long as the crtc_state->inherited flag is set. Once the
flag gets cleared (during initial commit for inactive pipes,
during the first userspace commit for active pipes), we
will naturally recompute all the sagv related state.

Now that all the sagv computation has been moved from the
skl+ watermark code into intel_bw_atomic_check() there is
no point in calling intel_bw_modeset_checks() before the
wm computation. Hide it within intel_bw_atomic_check().

The only thing between the current intel_bw_check_sagv_mask() call
site and intel_bw_atomic_check() is skl_wm_add_affected_planes()
which no longer depends on the sagv mask, so we can make life
a lot less confusing by calling intel_bw_check_sagv_mask() from
intel_bw_atomic_check() instead.

Move the bw_state->pipe_sagv_reject computation into intel_bw.c
where it belongs.
Previously we had a complicated dance between watermarks and
sagv which required this to be computed earlier, but that was
changed in commit 5e8146251f7b ("extract intel_bw_check_sagv_mask()")
which allows the whole thing to be cleaned up quite a bit.

I want to use the crtc_state->inherited flag to clean up some
of the early SAGV handling. To make that work nicely I need to
flag even the inactive crtcs as "inherited".
Since we can't expect user space to perform any real commits
on inactive crtcs we'll clear the flag already during
initial_commit().

Currently intel_bw_calc_min_cdclk() always adds the bw_state
to the atomic state. Not only does it result in potentially
redundant work later, it's also currently causing unwanted cdclk
changes during driver load.
Check if the dbuf bw is actually changing before we decide to
pull in the bw state.

intel_bw_crtc_min_cdclk() only depends on the pipe data rate,

stashing the resulting min_cdclk[] as well is redundant. Get

The rz-du driver uses GEM DMA helpers, but does not implement the
drm_driver .gem_prime_import_sg_table operation. This prevents
importing dmabufs. Fix it by implementing the missing operation using
the DRM_GEM_DMA_DRIVER_OPS_WITH_DUMB_CREATE() helper macro.
