Revert "i965: Use MESA_FORMAT_B8G8R8X8_SRGB for RGB visuals"

This reverts commit 839793680f99b8387bee9489733d5071c10f3ace.

The patch was breaking DRI3 because driGLFormatToImageFormat does not
handle MESA_FORMAT_B8G8R8X8_SRGB which ended up making it fail to
create the renderbuffer and it would later crash. It's not trivial to
add this format because there is no __DRI_IMAGE_FORMAT nor
__DRI_IMAGE_FOURCC define for the format either. I'm not sure how
difficult adding this would be and whether adding a new format would
require some sort of new version for DRI. Seeing as this might take a
while to fix I think it makes sense to just revert the patch in the
meantime in order to avoid regressing master.

It is also not handled in intel_gles3_srgb_workaround and there may be
other cases where it breaks.

mesa/blit: Don't require the same format for mulitisample blits

Previously the GL spec required that whenever glBlitFramebuffer is
used with either buffer being multisampled, the internal formats must
match. However the GL 4.4 spec was later changed to remove this
restriction. In the section entitled “Changes in the released
Specification of July 22, 2013” it says:

“Relax BlitFramebuffer in section 18.3.1 so that format conversion can
 take place during multisample blits, since drivers already allow this
 and some apps depend on it.”

If most drivers already allowed this in earlier versions I think it's
safe to assume that this is a spec bug and it should also be allowed
in all versions.

This patch just removes the restriction on desktop GL. For GLES there
are conformance tests that assert the previous behaviour so it is
probably safer to leave it in.

In some cases shaders want non-default rounding when converting float to
integer. This can be done in one go, so merge the two ops. This comes up
in the packUnorm4x8 & co functions, as well as a few random shaders.

other misc shaders.

8 years agonv50/ir: manually optimize multiplication expansion logic
Ilia Mirkin [Fri, 11 Dec 2015 05:40:15 +0000 (00:40 -0500)]
nv50/ir: manually optimize multiplication expansion logic

The conversion of 32-bit integer multiplies into 16-bit ones happens
after the regular optimization loop. However it's fairly common to
multiply by a small integer, rendering some of the expansion pointless.

Firstly, propagate immediates when possible into mul ops, secondly just
remove the ops when they are unnecessary.

Including the change to generate imad immediates, the effect is:

total instructions in shared programs : 6365463 -> 6351898 (-0.21%)
total gprs used in shared programs    : 728684 -> 728684 (0.00%)
total local used in shared programs   : 9904 -> 9904 (0.00%)
total bytes used in shared programs   : 44001576 -> 44036120 (0.08%)

                local        gpr       inst      bytes
    helped           0           0        3288           4
      hurt           0           0           0         842

It's easy for this to hurt bytes since we end up always generating the
8-byte form, while we can't always get rid of the immediate in question.

8 years agollvmpipe: fix layer/vp input into fs when not written by prior stages
Roland Scheidegger [Wed, 9 Dec 2015 03:56:15 +0000 (04:56 +0100)]
llvmpipe: fix layer/vp input into fs when not written by prior stages

ARB_fragment_layer_viewport requires that if a fs reads layer or viewport
index but it wasn't output by gs (or vs with other extensions), then it reads
0. This never worked for llvmpipe, and is surprisingly non-trivial to fix.
The problem is the mechanism to handle non-existing outputs in draw is rather
crude, it will simply redirect them to whatever is at output 0, thus later
stages will just get garbage. So, rather than trying to fix this up (which
looks non-trivial), fix this up in llvmpipe setup by detecting this case there
and output a fixed zero directly.
While here, also optimize the hw vertex layout a bit - previously if the gs
outputted layer (or vp) and the fs read those inputs, we'd add them twice
to the vertex layout, which is unnecessary.
And do some minor cleanup, slots don't require that many bits, there was some
bogus (but harmless) float/int mixup for psize slot too, make the slots all
unsigned (we always put pos at pos zero thus everything else has to be positive
if it exists), and make sure they are properly initialized (layer and vp index
slot were not which looked fishy as they might not have got set back to zero
when changing from a gs which outputs them to one which does not).

This fixes the failures in piglit's arb_fragment_layer_viewport group
(3 each for layer and vp).
