meta: Store precompiled msaa shaders for all supported sample counts

BLIT_MSAA_SHADER_2D_MULTISAMPLE_ARRAY_RESOLVE* shaders
in setup_glsl_msaa_blit_shader() are not recompiled

implementation continued using a 4X msaa shader, even if

In these two cases, the final allocation size is the product of three values:
one variable and two that are fixed constants at compile time.

In this commit, we move the explicit multiplication to involve only the
compile-time constants, preventing any overflow from that multiplication, (and
allowing calloc to catch any potential overflow from the remainining implicit

Eliminate several cases of multiplication in arguments to calloc

In commit 32f2fd1c5d6088692551c80352b7d6fa35b0cd09, 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.

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.

Revert "mesa: fix make tarballs"

This reverts commit 0fbb9a599df898d4e1166d6d6f00cb34a0524bea.

Rather than adding hacks around the issue drop the sources from the
final tarball, and re-add them back with 'make dist'. This fixes a
problem when running parallel 'make install' fails as it recreates
sources and triggers partial recompilation.

9 years agoi965: Modify dirty bit handling to support 2 pipelines.
Paul Berry [Sat, 11 Jan 2014 00:05:11 +0000 (16:05 -0800)]
i965: Modify dirty bit handling to support 2 pipelines.

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().
