In commit 32f2fd1c5d, several calls to
_mesa_calloc(x) were replaced with calls to calloc(1, x). This is strictly
equivalent to what the code was doing previously.
But for cases where "x" involves multiplication, now that we are explicitly
using the two-argument calloc, we can do one step better and replace:
calloc(1, A * B);
with:
calloc(A, B);
The advantage of the latter is that calloc will detect any overflow that would
have resulted from the multiplication and will fail the allocation, (whereas
the former would return a small allocation). So this fix can change
potentially exploitable buffer overruns into segmentation faults.

In commit 46d03d37bf I renamed a Makefile target

This is part of fixing extremely long runtimes on some piglit tests that
involve streaming vertex reuploads due to format conversions, and will
similarly be important for X performance, which relies on these flags.
A meta begin/end pair with MESA_META_DRAW_BUFFERS will change visible GL
state. We recreate the draw buffer enums from the buffer bitfield, which
changes GL_BACK to GL_BACK_LEFT (and GL_FRONT to GL_FRONT_LEFT).
This commit modifes the save/restore logic to instead copy the buffer enums
from the gl_framebuffer and then set them on restore using
_mesa_drawbuffers().
It's not clear how this breaks the benchmark in 82796, but fixing meta to not
leak the state change fixes the regression.
No piglit regressions.

The set of state atoms for compute shaders is currently empty; it will

Reviewed-by: Jordan Justen <jordan.l.justen@intel.com>
The hardware state for compute shaders is almost entirely orthogonal
to the hardware state for 3D rendering. To avoid sending unnecessary
state to the hardware, we'll need to have a separate set of state
atoms for the compute pipeline and the 3D pipeline. That means we
need to maintain two separate sets of dirty bits to determine which
state atoms need to be run.
But the dirty bits are not completely independent; for example, if
BRW_NEW_SURFACES is flagged while doing 3D rendering, then not only do
we need to re-run 3D state atoms that depend on BRW_NEW_SURFACES, but
we also need to re-run compute state atoms that depend on
BRW_NEW_SURFACES. But we'll also need to re-run those state atoms the
next time the compute pipeline is run.
To accomplish this, we record two sets of dirty bits, one for each
pipeline. When bits are dirtied (via SET_DIRTY_BIT() or
SET_DIRTY_ALL()) we set them to the dirty state in both pipelines.
When brw_state_upload() is run, we clear the dirty bits just for the
pipeline that was run.
Note that since the number of pipelines is known at compile time to be
2, the compiler should unroll the loops in SET_DIRTY_BIT() and
SET_DIRTY_ALL().
