This patch both adds support for probing & filtering DRM nodes
and switches away from using the GRALLOC_MODULE_PERFORM_GET_DRM_FD
gralloc call.

Currently the filtering is based just on the driver name,
and the desired name is supplied using the "drm.gpu.vendor_name"
Android property.

The filtering itself is done using the newly introduced
libdrm drmHandleMatch() call.

Rob Herring authored 6 years ago and Robert Foss committed 6 years ago

Maintaining both flink names and prime fd support which are provided by
2 different gralloc implementations is problematic because we have a
dependency on a specific gralloc implementation header.

This mostly disables the dependency on the gralloc implementation and
headers. The dependency on GRALLOC_MODULE_PERFORM_GET_DRM_FD remains for
now, but the definition is added locally to remove the header
dependency.

drm_gralloc support can be enabled by setting
BOARD_USES_DRM_GRALLOC=true in BoardConfig.mk.

For all of the OpFOrd* comparisons except OpFOrdNotEqual the hardware
should probably already return false if one of the operands is NaN so
we don’t need to have an explicit check for it. This seems to at least
work on Intel hardware. This should reduce the number of instructions
generated for the most common comparisons.

For what it’s worth, the original code to handle this was added in
e062eb64. The commit message for that says that it was to fix
some CTS tests for OpFUnord* opcodes. Even if the hardware doesn’t
handle NaNs this patch shouldn’t affect those tests. At any rate they
have since been moved out of the mustpass list. Incidentally those
tests fail on the nvidia proprietary driver so it doesn’t seem like
handling NaNs correctly is a priority.

The logic was flawed, since mul(x,y) will be <= 0 (exactly 0) when
the sign is the same but both numbers are sufficiently small
(if the product is smaller than 2^-128).
This could apparently lead to emitting a sufficient amount of
additional bogus vertices to overflow the allocated array for them,
hitting an assertion (still safe with release builds since we just
aborted clipping after the assertion in this case - I'm however unsure
if this is now really no longer possible, so that code stays).
Not sure if the additional vertices could cause other grief, I didn't
see anything wrong even when hitting the assertion.

Essentially, both +-0 are treated as positive (the vertex is considered
to be inside the clip volume for this plane), so integrate the logic
determining different sign into the branch there.

Some analysis suggests that all short immediates are sign-extended. The
insnCanLoad logic already accounted for this, but we could still pick
the wrong form when emitting actual instructions that support both short
and long immediates (with the long form usually having additional
restrictions that insnCanLoad should be aware of).

This also reverses a bunch of commits that had previously "worked
around" this issue in various emitters:

9c632245: gm107/ir: make use of ADD32I for all immediates

When draw buffers are changed on a bound framebuffer, DrawBufferAllocate()
hook should be called. However, it is missing in update_framebuffer with
window-system framebuffer, in which FB's draw buffer state should match
context state, potentially resulting in a change.

Note: This is needed because gallium delays creating the front buffer,
      i965 works fine without this change.

V2 (Timothy Arceri):
 - Rebased on merged/simplified DrawBuffer driver function
 - Move DrawBuffer call outside fb->ColorDrawBuffer[0] !=

The paths which sample with the clear color are now using a getter which
performs the sRGB decode needed to enable this fast clear.

This path can be exercised by fast-clearing a texture, then performing
an operation which requires sRGB decoding. Test coverage for this

* Shader texture calls:
  - spec@ext_texture_srgb@tex-srgb
