* freedreno/ir3: fix grouping issue w/ reverse swizzlesRob Clark2016-04-181-1/+17
| | | | | | | | | | | | | | | | | | | | | | | When we have something like: MOV OUT[n], IN[m].wzyx the existing grouping code was missing a potential conflict. Due to input needing to be sequential scalar regs, we have: IN: x <-> y <-> z <-> w which would be grouped to: OUT: w <-> z2 <-> y2 <-> x (where the 2 denotes a copy/mov) but that can't actually work. We need to realize that x and w are already in the same chain, not just that they aren't both already in new chain being built. With this fixed, we probably no longer need the hack from f68f6c0.

* Revert "freedreno/a4xx: better occlusion/sample counting"Rob Clark2016-04-131-6/+1
| | | | | | | | | | This reverts commit 62fa868728c729152af0d7cecd1d3e47e831cb7d. dEQP-GLES3.functional.occlusion_query.* was unhappy about that change. Still not really sure *what* the other slots in the sample results buffer are. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a4xx: rasterizer_discard supportRob Clark2016-04-131-0/+17
| | | | | | | | | | | | | | | | | This one is slightly annoying, since trying to write RBRC from draw would clobber values set in the tiling/gmem code. We could do command- stream patching for RBRC, as is done on a3xx. Although since it seems to be a rarely used feature, it is easier just to do RMW to set/clear the bit. Fixes dEQP-GLES3.functional.rasterizer_discard.basic.write_depth_triangles and related tests. a3xx still needs the same feature, although there it probably makes more sense to take advantage of the existing cmdstream patching which is required for RBRC for other reasons.

* freedreno/ir3: fix array textures on a4xxRob Clark2016-04-131-3/+9
| | | | | | | | Seems like a4xx needs offset added to array index for all arrays, whereas a3xx only for cubemap arrays. Fixes a whole swath of dEQP fails (roughly *sampler2darray*). Signed-off-by: Rob Clark <[email protected]>
* freedreno: fix stream-out offset handling for lines/trisRob Clark2016-04-131-1/+1
| | | | | | | | We need to increment offset by # of vertices, not by # of prims. Fixes a bunch of dEQP fails involving prims other than points. For example, dEQP-GLES3.functional.transform_feedback.position.lines_separate Signed-off-by: Rob Clark <[email protected]>
* freedreno: fix handling for stream-out offsetsRob Clark2016-04-131-1/+2
| | | | | | | | | | | | | | | | | | If changed && append, we shouldn't be resetting the internal offset back to zero. This fixes issues w/ sequences like: glBeginTransformFeedback() glDraw() glPauseTransformFeedback() glDraw() glResumeTransformFeedback() glDraw() glEndTransformFeedback() Fixes dEQP-GLES3.functional.transform_feedback.array.separate.points.lowp_vec3 and related tests.

* freedreno: fix max-line-widthRob Clark2016-04-131-0/+10
| | | | | | | | | | | dEQP noticed that we were advertising completely bogus values. The actual maximum is 127.0f. *But* we have to use an artifically low maximum to work around a bug in the dEQP test, which gets confused when the max line width is too large and lines start going off-screen.

* freedreno/ir3: use (ss) instead of (sy) for ldlvRob Clark2016-04-131-1/+7

* freedreno/ir3: cleanup double cmps.s from frontendRob Clark2016-04-131-0/+31
| | | | | | | | | | | | | Since we cannot mov into a predicate register, the frontend uses a 'cmps.s p0.x, cond, 0' as a stand-in for mov to p0.x. It does this since it has no way to know that the source cond instruction (ie. for a kill, br, etc) will only be used to write the predicate reg. Detect this, and re-write the instruction writing p0.x to skip the original cmps.[sfu]. (It is done like this, rather than re-writing the dest of the first cmps.[sfu] in case the first cmps.[sfu] actually has other users.) Signed-off-by: Rob Clark <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add PIPE_CAP to determine if the GL extension 'GL_ARB_framebuffer_no_attachments' shall be supported. The driver is required to support 'PIPE_FORMAT_NONE' via its 'is_format_supported()' callback in order to determine the MSAA modes the hardware supports so that values requested from the application using 'GL_ARB_framebuffer_no_attachments' may be quantized to what the hardware expects. V.2: Fix doc for a more detailed description of the PIPE_CAP and the corresponding GL constant. V.3: Renamed and repurposed once again. V.4: Remove CAP from cap_mapping array.

* freedreno/ir3: insert extra move into phiRob Clark2016-04-051-0/+10
| | | | | | | | | | | | | | | | | We had an implicit assumption that the phi src was assigned in it's source (pred) block leading into the phi. But this is not true with NIR, so we can't just ignore the source block specified in the nir_phi_src. Insert an extra mov in the source block. If it is not required the CP pass will take it back out again. Fixes: ./tests/spec/glsl-1.10/execution/vs-call-in-nested-loop.shader_test ./tests/spec/glsl-1.10/execution/vs-inner-loop-modifies-outer-loop-var.shader_test and probably others.

* freedreno/ir3: eliminate unnecessary absneg'sRob Clark2016-04-052-3/+26
| | | | | | | | | | | | | | | | The frontend inserts (abs) and (neg)'s to convert between NIR boolean (~0/0) and native boolean (1/0). So we'd end up with things like: cmps.s.ge r1.x, ... absneg.s r1.x, (neg)r1.x absneg.s r1.x, (abs)r1.x sel.b32 r2.x, r0.x, r1.x, r0.y The (neg) already gets collapsed due to the following (abs). Now by realizing that r1.x comes from a cmps.s instruction, we can drop the (abs) as well. Signed-off-by: Rob Clark <[email protected]>
* freedreno/ir3: deal with duplicate phi sourcesRob Clark2016-04-041-5/+20
| | | | | | | | | | | | | Otherwise we end up with funny things like: mov.f32f32 r0.x, r1.y mov.f32f32 r0.x, r1.y (It doesn't happen as much after fixing the problem w/ CP into phi src, but it can still happen since we aren't too clever about generating phi sources in the first place.)

| | | | | | | | | | | | | Been on my TODO list for a while. If nothing else this will make gdb properly grok the opc_t enum. This first step preserves ir3_instruction::category (with an added assert that category matches what is encoded in opc_t). Next step is to drop the category field (and arg to ir3_instr_create()), but that is split into next commit for bisectability and so that we can run piglit in the intermediate state to flush out any problems.
