* r600g/sb: fix scheduling of PRED_SET instructionsVadim Girlin2013-05-272-2/+18
| | | | | | | | | | | | | | PRED_SET instructions that update exec mask should be scheduled immediately prior to the "if-then-else" block, because any instruction that is inserted after alu clause with PRED_SET and before conditional block is also conditionally executed by hw (exec mask is already updated at that moment). Propbably it's better to make PRED_SET a part of conditional "if-then-else" block in the IR to handle this more cleanly, but for now this temporary solution should prevent the problem.

* r600g/sb: fix handling of preloaded inputs for compute shadersVadim Girlin2013-05-251-0/+4
| | | | | | | | | | For compute shaders we need to let the backend know that GPRs 0 and 1 are preloaded with some compute-specific input values, otherwise any use of these regs without previous definition is considered as undefined value and usually is simply replaced with 0.

* r600g/sb: relax register allocation for compute shadersVadim Girlin2013-05-242-2/+16
| | | | | | | | | | | | | | We have to assume that all GPRs in compute shader can be indirectly addressed because LLVM backend doesn't provide any indirect array info. That's why for compute shaders GPR array is created that covers all used GPRs (0..r600_bytecode::ngpr-1), but this seriously restricts register allocation in sb. This patch checks for actual use of indirect access in the shader and if it's not used then GPR array is not created, so that regalloc is not unnecessarily restricted.

| | | | | | | | | | | | | | | It turns out the MI_LOAD_REGISTER_IMM approach doesn't work on Haswell, and regressed essentially all the transform feedback Piglit tests. This morally reverts eaa6fbe6d54dc99efac4ab8e800edef65ce8220d. However, the code is still simpler than it was. On BeginTransformFeedback, we simply flush the batch and set the SOL reset flag so that the next batch will start with zeroed offsets. There's still no software counting.

* softpipe: change TEX_TILE_SIZE and NUM_TEX_TILE_ENTRIESRoland Scheidegger2013-05-221-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Initially we had NUM_TEX_TILE_ENTRIES of 50, however this was using too much memory (mostly because the tile cache is operating on fixed max current sampler views which could be fixed but that's another topic). So it was decreased to 4. However this is a ridiculously low number which can't actually really work (the number of tiles needed for as little as a single quad with linear_mipmap_linear is 2 to 8 for a 2d texture, and 4 to 16 for a 3d texture), as it just about guarantees there will be cache thrashing sometimes (just about always for 3d textures in fact, since while there are 4 entries the cache is direct mapped). So increase that number to 16 (which is still on the low side for direct mapped cache though I guess using something like 4-way associativity would be more effective than increasing this further) which has at least some good chance to avoid thrashing. Since we don't want to increase memory requirements however in turn decrease the tile size accordingly from 64 to 32 (as a bonus point this also decreases the cost of texture thrashing which might still happen sometimes). I've seen performance improvement in the order of factor ~200 (specifically, drawing the first frame from the replay from bug 41787 needs "only" ~10s instead of ~30min, meaning I can actually compare the output with other drivers...) with this.

* llvmpipe: disable simple_shader optimizationRoland Scheidegger2013-05-221-1/+6
| | | | | | | | | | | | | | This optimization disabled mask checks if the shader is simple enough. While this should work correctly, the problem is that it can hide real issues because shaders in practice are usually complex enough (8 instructions or 1 texture is already enough) so this doesn't get used, whereas dumbed-down tests which should hit all the same code paths suddenly do something quite different. This was the reason that bug 41787 could not be easily tracked as stencil test not working correctly (piglit would in fact have failed some tests without that optimization). So disable it for now, it's unclear if it's much of a win in any case. Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: fix early depth test / late depth write stencil issuesRoland Scheidegger2013-05-221-5/+12
| | | | | | | | | | | | | | We actually did early depth/stencil test and late depth/stencil write even when the shader could kill the fragment (alpha test or discard). Since it matters for the new stencil value if the fragment is killed by depth/stencil test or by the shader (in which case it will not reach the depth/stencil test) this simply cannot work (we also would possibly skip writing the new stencil value due to mask checks but this is a secondary issue). So use late depth test / late depth write instead in this case. (No piglit changes as it doesn't seem to hit such bogus early depth test / late depth write path.)

* llvmpipe: fix issue with not writing new stencil valuesRoland Scheidegger2013-05-222-4/+7
| | | | | | | | | | | | | | | We did mask checks between depth/stencil testing and depth/stencil write. This meant that if the depth/stencil test killed off all fragments we never actually wrote the new stencil value. This issue affected all early/late test/write combinations. So move the mask check after depth/stencil write (for early depth test, could do the same for late depth test but might not be worth it at that point so just skip it there). This addresses https://bugs.freedesktop.org/show_bug.cgi?id=41787. Piglit does not hit this issue because of the simple_shader optimization in generate_fs_loop() which means we're skipping the mask checks. Reviewed-by: Jose Fonseca <[email protected]>
