12 years agoi965: Do texture swizzling in hardware on Haswell.
Kenneth Graunke [Fri, 21 Sep 2012 10:13:36 +0000 (03:13 -0700)]
i965: Do texture swizzling in hardware on Haswell.

Haswell supports EXT_texture_swizzle and legacy DEPTH_TEXTURE_MODE
swizzling by setting SURFACE_STATE entries.  This means we don't have to
bake the swizzle settings into the shader code by emitting MOV
instructions, and thus don't have to recompile shaders whenever the
swizzles change.

Unfortunately, we can't handle GL_ALPHA this way: unlike all the others,
which store the comparison result in the .r channel (and possibly others
as well), GL_ALPHA puts it in the .a channel.  The GLSL 1.30+ style
functions which return a float always simply return the .r channel,
which would be zero if we handled this as a surface override.  In this
case, fall back to doing it the old way.  DEPTH_TEXTURE_MODE = GL_ALPHA
isn't an interesting performance path anyway.

12 years agoi965/blorp: Increase Y alignment for multisampled stencil blits.
Paul Berry [Wed, 12 Sep 2012 18:13:49 +0000 (11:13 -0700)]
i965/blorp: Increase Y alignment for multisampled stencil blits.

This patch is a band-aid fix for a bug in commit 5fd67fa (i965/blorp:
Reduce alignment restrictions for stencil blits), which causes
multisampled stencil blits to work incorrectly on Sandy Bridge.

When blitting to or from a normal stencil buffer, we have to use a
coordinate transformation that swizzles coordinates to account for the
fact that stencil buffers use W tiling, but the most similar tiling
format available for textures and render targets is Y tiling.  The
differences between W and Y tiling cause pixels to be scrambled within
a block of size 8x4 (width x height) as measured relative to a W tile,
or 16x2 as measured relative to a Y tile.  So in order to make sure
that pixels at the edges of the blit aren't lost, we need to align the
rendering rectangle (and the buffer sizes) to multiples of the 8x4
block size.  This alignment happens in the brw_blorp_blit_params
constructor, whereas the determination of how to swizzle the
coordinates happens during code generation, in the
brw_blorp_blit_program class.

When blitting to or from a multisampled stencil buffer, the coordinate
swizzling is more complex, because it has to account for the
interleaving pattern of samples, which uses 4x4 blocks for 4x MSAA and
8x4 blocks for 8x MSAA.  The end result is that if multisampling is in
use, the 16x2 block size (relative so a Y tile) needs to be expanded
to 16x4, and the corresponding size relative to a W tile expands to
8x8.

The problem doesn't affect Ivy Bridge severely enough to crop up in
Piglit tests because on Ivy Bridge we have to disable multisampling
when blitting *to* a multisampled stencil buffer (the blorp compiler
generates code to compensate for the fact that multisampling is
disabled).  However I suspect a bug is still present because we don't
disable multisampling when blitting *from* a multisampled stencil
buffer.

This patch fixes the problem by doubling the vertical alignment
requirement when blitting to or from a multisampled stencil buffer,
and multisampling has not been disabled.

In the long run I would like to rework the brw_blorp_blit_params
constructor--it's difficult to follow and has had several subtle bugs
like this one.  However this band-aid fix should be suitable for
cherry-picking to release branches.

Fixes Piglit tests "unaligned-blit {2,4} stencil {msaa,upsample}" on
Sandy Bridge.

NOTE: This is a candidate for stable release branches.

r300g: Init regalloc state during context creation

Initializing the regalloc state is expensive, and since it is always
the same for every compile we only need to initialize it once per
context.  This should help improve shader compile times for the driver.

12 years agor600g: Use LOOP_START_DX10 for loops

r600g: Use LOOP_START_DX10 for loops

LOOP_START_DX10 ignores the LOOP_CONFIG* registers, so it is not limited
to 4096 iterations like the other LOOP_* instructions.  Compute shaders
need to use this instruction, and since we aren't optimizing loops with
the LOOP_CONFIG* registers for pixel and vertex shaders, it seems like
we should just use it for everything.
