[Intel-gfx] [PATCH v2 1/4] drm/i915/gt: Explicitly clear BB_OFFSET for new contexts

[Ramalingam C]

From: Chris Wilson <chris@chris-wilson.co.uk>

Even though the initial protocontext we load onto HW has the register
cleared, by the time we save it into the default image, BB_OFFSET has
had the enable bit set. Reclear BB_OFFSET for each new context.

[Intel-gfx] [PATCH v2 2/4] drm/i915/selftests: Check for incomplete LRI from the context image

[Ramalingam C]

From: Chris Wilson <chris@chris-wilson.co.uk>

In order to keep the context image parser simple, we assume that all
commands follow a similar format. A few, especially not MI commands on
the render engines, have fixed lengths not encoded in a length field.
This caused us to incorrectly skip over 3D state commands, and start
interpreting context data as instructions. Eventually, as Daniele
discovered, this would lead us to find addition LRI as part of the data
and mistakenly add invalid LRI commands to the context probes.

Stop parsing after we see the first !MI command, as we know we will have
seen all the context registers by that point. (Mostly true for all gen so far,
though the render context does have LRI after the first page that we
have been ignoring so far. It would be useful to extract those as well
so that we have the full list of user accessible registers.)

Similarly, emit a warning if we do try to emit an invalid zero-length
LRI.

[Intel-gfx] [PATCH v2 3/4] drm/i915/selftest: Always cancel semaphore on error

[Ramalingam C]

From: Chris Wilson <chris@chris-wilson.co.uk>

Ensure that we always signal the semaphore when timing out, so that if it
happens to be stuck waiting for the semaphore we will quickly recover
without having to wait for a reset.

[Intel-gfx] [PATCH v2 4/4] drm/i915/selftest: Clear the output buffers before GPU writes

[Ramalingam C]

From: Chris Wilson <chris@chris-wilson.co.uk>

When testing whether we can get the GPU to leak information about
non-privileged state, we first need to ensure that the output buffer is
set to a known value as the HW may opt to skip the write into memory for
a non-privileged read of a sensitive register. We chose POISON_INUSE (0x5a)
so that is both non-zero and distinct from the poison values used during
the test.

  Use i915_gem_object_pin_map_unlocked
