drm/i915/guc: Fix error capture for virtual engines

GuC based register dumps in error capture logs were basically broken
for virtual engines. This can be seen in igt@gem_exec_balancer@hang:
  [IGT] gem_exec_balancer: starting subtest hang
  [drm] GPU HANG: ecode 12:4:e1524110, in gem_exec_balanc [6388]
  [drm] GT0: GUC: No register capture node found for 0x1005 / 0xFEDC311D
  [drm] GPU HANG: ecode 12:4:00000000, in gem_exec_balanc [6388]
  [IGT] gem_exec_balancer: exiting, ret=0

The test causes a hang on both engines of a virtual engine context.
The engine instance zero hang gets a valid error capture but the
non-instance-zero hang does not.

Fix that by scanning through the list of pending register captures
when a hang notification for a virtual engine is received. That way,
the hang can be assigned to the correct physical engine prior to
starting the error capture process. So later on, when the error capture
handler tries to find the engine register list, it looks for one on
the correct engine.

Also, sneak in a missing blank line before a comment in the node
search code.

v2: Fix null pointer deref on non-GuC platforms.

i915/pmu: Add support for total context runtime for GuC back-end

GPU accumulates the context runtime in a 32 bit counter - CTX_TIMESTAMP
in the context image. This value is saved/restored on context switches.
KMD accumulates these values into a 64 bit counter taking care of any
overflows as needed. This count provides the basis for client specific
busyness in the fdinfo interface.

KMD accumulation happens just before the context is unpinned and when
context switches out. This works for execlist back-end since execlist
scheduling has visibility into context switches. With GuC mode, KMD does
not have visibility into context switches and this counter is
accumulated only when context is unpinned. Context is unpinned once the
context scheduling is successfully disabled. Disabling context
scheduling is an asynchronous operation. Also if a context is servicing
frequent requests, scheduling may never be disabled on it.

For GuC mode, since updates to the context runtime may be delayed, add
hooks to update the context runtime in a worker thread as well as when
a user queries for it.

Limitation:
- If a context is never switched out or runs for a long period of time,
  the runtime value of CTX_TIMESTAMP may never be updated, so the
  counter value may be unreliable. This patch does not support such
  cases. Such support must be available from the GuC FW and it is WIP.

drm/i915: Use correct huge page manager for MTL

MTL currently uses gen8_ppgtt_insert_huge when managing huge pages.
This is because MTL reports as not supporting 64K pages, or more
accurately, the system that reports whether a platform has 64K pages
reports false for MTL. This is only half correct, as the 64K page support
reporting system only cares about 64K page support for LMEM, which MTL
doesn't have.

MTL should be using xehpsdv_ppgtt_insert_huge. However, simply changing
over to using that manager doesn't resolve the issue because MTL is
expecting the virtual address space for the page table to be flushed after
initialization, so we must also add a flush statement there.

drm/i915/guc: Actually return an error if GuC version range check fails

Dan Carpenter pointed out that 'err' was not being set in the case
where the GuC firmware version range check fails. Fix that.

Note that while this is a bug fix for a previous patch (see Fixes tag
below). It is an exceedingly low risk bug. The range check is
asserting that the GuC firmware version is within spec. So it should
not be possible to ever have a firmware file that fails this check. If
larger version numbers are required in the future, that would be a
backwards breaking spec change and thus require a major version bump,
in which case an old i915 driver would not load that new version anyway.

drm/i915/mtl: workaround coherency issue for Media

This patch implements Wa_22016122933.

In MTL, memory writes initiated by the Media tile update the whole
cache line, even for partial writes. This creates a coherency
problem for cacheable memory if both CPU and GPU are writing data
to different locations within a single cache line.
This patch circumvents the issue by making CPU/GPU shared memory
uncacheable (WC on CPU side, and PAT index 2 for GPU). Additionally,
it ensures that CPU writes are visible to the GPU with an
intel_guc_write_barrier().

While fixing the CTB issue, we noticed some random GSC firmware
loading failure because the share buffers are cacheable (WB) on CPU
side but uncached on GPU side. To fix these issues we need to map
such shared buffers as WC on CPU side. Since such allocations are
not all done through GuC allocator, to avoid too many code changes,
the i915_coherent_map_type() is now hard coded to return WC for MTL.

v2: Simplify the commit message(Matt).

drm/i915/gt: Avoid out-of-bounds access when loading HuC

When HuC is loaded by GSC, there is no header definition for the kernel
to look at and firmware is just handed to GSC. However when reading the
version, it should still check the size of the blob to guarantee it's not
incurring into out-of-bounds array access.

If firmware is smaller than expected, the following message is now
printed:

# echo boom > /lib/firmware/i915/dg2_huc_gsc.bin
# dmesg | grep -i huc
[drm] GT0: HuC firmware i915/dg2_huc_gsc.bin: invalid size: 5 < 184
[drm] *ERROR* GT0: HuC firmware i915/dg2_huc_gsc.bin: fetch failed -ENODATA
...

Even without this change the size, header and signature are still
checked by GSC when loading, so this only avoids the out-of-bounds array
access.

drm/i915: disable sampler indirect state in bindless heap

By default the indirect state sampler data (border colors) are stored
in the same heap as the SAMPLER_STATE structure. For userspace drivers
that can be 2 different heaps (dynamic state heap & bindless sampler
state heap). This means that border colors have to copied in 2
different places so that the same SAMPLER_STATE structure find the
right data.

This change is forcing the indirect state sampler data to only be in
the dynamic state pool (more convenient for userspace drivers, they
only have to have one copy of the border colors). This is reproducing
the behavior of the Windows drivers.

drm/msm/dpu: catalog: add comments regarding DPU_CTL_SPLIT_DISPLAY

For sm8150+ the DPU_CTL_SPLIT_DISPLAY should be replaced with
DPU_CTL_ACTIVE_CFG support (which supports having a single CTL for both
interfaces in a split). Add comments where this conversion is required.

much more stable. To ease configuration reuse move ubwc_swizzle and
highest_bank_bit data to separate structure.
