* glx: Create proper server dependency for GLX_EXT_create_context_es2_profileIan Romanick2015-04-151-11/+1
| | | | | | | | | | | | | | | | | | | | Previously GLX_EXT_create_context_es2_profile was marked as "direct only" so that it would not depend on server support. Since the extension required functions that are part of GLX_ARB_create_context_profile, support for the EXT was disabled if the ARB was not supported. This was complete rubbish. If the server supported the ARB but not the EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result in GLXBadProfileARB. Instead of the misguided hack, make GLX_EXT_create_context_es2_profile properly depend on server support by not marking it as "direct only."

* i965/fs: Only emit FS_OPCODE_PLACEHOLDER_HALT if there are discardsBen Widawsky2015-04-141-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based originally on a patch from Ken in May 2014 of the same title. Things changed enough that I didn't feel comfortable leaving his authorship. v2: Replace fp->UsesKill with wm_prog_data->uses_kill. Since Ken took the time to also explain the difference to me, here is his explanation for posterity: "fp->UsesKill indicates that a ARB_fragment_program shader uses the KIL instruction, or that a GLSL shader uses the "discard" insntruction (which are analogous). On Gen4-5, we sometimes have to simulate OpenGL's "Alpha Test" feature by emitting shader code that implicitly does a "discard" instruction. In the key setup, we do: /* key->alpha_test_func means simulating alpha testing via discards, * so the shader definitely kills pixels. */ prog_data.uses_kill = fp->program.UsesKill || key->alpha_test_func; Even though the shader may not technically contain a "discard", we need to act as if it does. I've also been trying to move the i965 state setup code to use brw_wm_prog_key for everything, rather than poking at core Mesa's gl_program/gl_fragment_program/gl_shader/gl_shader_program structures. --Ken" Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* i965/fs: Create a has_side_effects for fs_instBen Widawsky2015-04-142-0/+7
| | | | | | | | | | | | | | | | | | | When an instruction has a side effect, it impacts the available options when reordering an instruction. As the EOT flag is an implied write to the render target in the FS, it can be considered a side effect. This patch shouldn't actually have any impact on the current code since the EOT flag implies that the opcode is already one with side effects, FS_OPCODE_FB_WRITE. The next patch however will introduce an optimization whereby the EOT flag can occur with an opcode SHADER_OPCODE_TEX, and as that instruction will perform the same implied write to the render target, it cannot be reordered. v2: Remove extra whitespace (Matt) Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]>

* i965/skl: Use an exec size of 8 to initialise the message headerNeil Roberts2015-04-142-2/+2
| | | | | | | | | | | | | | | | | | Commit e93566a15c61c33faa changed the message header code needed to make Skylake use SIMD4x2 so that it uses a register with width 4 instead of 8 as the source register in the send message. However it also changed the width for the dest in the MOV instruction which is used to initialise the header register with the values from g0. The width of the destination is used to determine the exec size in brw_set_dest so this would end up making the MOV have an exec size of 4. I think this would end up leaving the top half of the register uninitialised. The top half of the header has meaningful values so this probably isn't a good idea. This patch just casts the dest register for the MOV instruction back to a vec8 to fix it. It doesn't cause any changes to a Piglit run. Reviewed-by: Ben Widawsky <[email protected]>
* i965/fs: Always invert predicate of SEL with swapped argumentsIan Romanick2015-04-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Commit b616164 added an optimization of b2f generation of a comparison. It also included an extra optimization of one of the comparison values is a constant of zero. The trick was that some value was known to be zero, so that value could be used in the SEL instruction instead of potentially loading 0.0 into a register. This change switched the order of the arguments to the SEL, and, for some unknown reason, I thought that the predicate should therefore only be inverted for the == case. Clearly, it should always be inverted. Fixes piglit fs-notEqual-of-expression.shader_test and fs-equal-of-expression.shader_test. v2: Don't do the "register already has zero" optimization for the '== 0' case. In that case, the register does not have zero when we want to produce a zero result.

* i965: Implement proper workaround for Gen4 GPU CONSTANT_BUFFER hangs.Kenneth Graunke2015-04-141-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | I finally managed to dig up some information on our mysterious GPU hangs. A wiki page from the Crestline validation team mentions that they found a GPU hang in "Serious Sam 2" (on Windows) with remarkably similar conditions to the ones we've seen in Google Chrome and glmark2. Apparently, if WM_STATE has "PS Use Source Depth" enabled, CC_STATE has most depth state disabled, and you issue a CONSTANT_BUFFER command and immediately draw, the depth interpolator makes a small mistake that leads to hangs. Most of the traces I looked at contained a CONSTANT_BUFFER packet immediately followed by 3DPRIMITIVE, or at least very few packets. It appears they also have "PS Use Source Depth" enabled - either at the hang, or a little before it. So I think this is our bug. The workaround is to emit a non-pipelined state packet after issuing a CONSTANT_BUFFER packet. This is really similar to the workaround I developed in commit c4fd0c9052dd391d6f2e9bb8e6da209dfc7ef35b. v2: Fix word-wrapping issues.
