8 years agoi965: Make BLORP's BlitFramebuffer follow the GL 4.4 sRGB rules.
Kenneth Graunke [Tue, 2 Aug 2016 04:56:38 +0000 (21:56 -0700)]
i965: Make BLORP's BlitFramebuffer follow the GL 4.4 sRGB rules.

OpenGL 4.4 specifies that BlitFramebuffer should perform sRGB encode
and decode like ES 3.x does, but only when GL_FRAMEBUFFER_SRGB is
enabled.  This is technically incompatible in certain cases, but is
more consistent across GL, ES, and WebGL, and more flexible.

The NVIDIA 367.35 drivers appear to follow this behavior.

For the awful spec analysis, please read Piglit's
tests/spec/arb_framebuffer_srgb/blit.c, which explains the differences
between GL 4.1, 4.2, 4.3 (2012), 4.3 (2013), and 4.4, and why this
is the right rule to implement.

Note that ctx->Color.sRGBEnabled is initialized to _mesa_is_gles(ctx),
and ES doesn't have enable/disable flags for GL_FRAMEBUFFER_SRGB, so
it's effectively on all the time.  This means the ES behavior should
be unchanged.

i965: Drop the "do resolves in sRGB" hack.

I've never quite understood the purpose of this hack - supposedly,
doing resolves in the sRGB colorspace is slightly more accurate.

Currently, BlitFramebuffer() ignores sRGB encoding and decoding
on OpenGL, although it encodes and decodes in GLES 3.x.

The updated OpenGL 4.4 rules also allow for encoding and decoding
if GL_FRAMEBUFFER_SRGB is enabled, allowing the application to
control what colorspace blits are done in.  I don't think this hack
makes any sense in such a world - the application can do what it
wants, and we shouldn't second guess them.

A related Piglit patch, "Make multisample accuracy test set
GL_FRAMEBUFFER_SRGB when resolving." makes the Piglit MSAA accuracy
test explicitly request SRGB encoding/decoding during resolves when
running "srgb" subtests.  Without that patch, this commit will regress
those tests, but with it, they should continue to work just fine.

nir: Make nir_opt_remove_phis see through moves.

I found a shader in Tales of Maj'Eyal that contains:

        if ssa_21 {
                block block_1:
                /* preds: block_0 */
                ...instructions that prevent the select peephole...
                vec1 32 ssa_23 = imov ssa_4
                vec1 32 ssa_24 = imov ssa_4.y
                vec1 32 ssa_25 = imov ssa_4.z
                /* succs: block_3 */
        } else {
                block block_2:
                /* preds: block_0 */
                vec1 32 ssa_26 = imov ssa_4
                vec1 32 ssa_27 = imov ssa_4.y
                vec1 32 ssa_28 = imov ssa_4.z
                /* succs: block_3 */
        }
        block block_3:
        /* preds: block_1 block_2 */
        vec1 32 ssa_29 = phi block_1: ssa_23, block_2: ssa_26
        vec1 32 ssa_30 = phi block_1: ssa_24, block_2: ssa_27
        vec1 32 ssa_31 = phi block_1: ssa_25, block_2: ssa_28

Here, copy propagation will bail because phis cannot perform swizzles,
and CSE won't do anything because there is no dominance relationship
between the imovs.  By making nir_opt_remove_phis handle identical moves,
we can eliminate the phis and rewrite everything to use ssa_4 directly,
so all the moves become dead and get eliminated.

I don't think we need to check "exact" - just the alu sources.
Presumably phi sources should match in their exactness.
