* radeonsi: use SPI_SHADER_COL_FORMAT fields instead of export_16bpcMarek Olšák2016-01-227-38/+91
| | | | | | | | | | | | | This does change the behavior slightly: If a shader writes COLOR[i] and that color buffer isn't bound, the shader will export MRT_NULL instead and discard the IR tree that calculates the output. The only exception is alpha-to-coverage, which requires an alpha export. v2: - update a comment about 16BPC - account for MRTZ when when fixing alpha-test/kill Reviewed-by: Nicolai Hähnle <[email protected]>

* llvmpipe: warn about illegal use of objects in different contextsRoland Scheidegger2016-01-213-1/+32
| | | | | | | | | | | Doing that is clearly a bug. We can't quite assert as st/mesa may hit this, but increase at least visibility of it a bit. (For the non-refcounted objects it would be illegal too, but we can't detect that unless we'd store the context ourselves. Plus, those don't tend to cause random crashes at context or object destruction time... So just sampler views, surfaces and so targets for now.) Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe,i915: add back NEW_RASTERIZER dependency when computing vertex infoRoland Scheidegger2016-01-212-3/+5
| | | | | | | | | | | | | | | | | | | | I removed this mistakenly in 2dbc20e45689e09766552517a74e2270e49817b5. I actually thought it should not be necessary and a piglit run didn't show any differences, but this shouldn't have been in there. draw_prepare_shader_outputs() is in fact dependent on NEW_RASTERIZER. The new polygon-mode-facing test indeed shows why this is necessary, there's lots of invalid reads and writes with valgrind (also crashes without valgrind), because the pre-pipeline vertex size doesn't match the post-pipeline vertex size (note this won't help much with stages which don't have the prepare hook which can grow the vertex size, in particular the wide point stage, but this isn't used by llvmpipe). The test still won't pass, of course, but it is only usage of uninitialized values now, which is much less dangerous... (Albeit I'm pretty sure for i915 it really is not needed anymore as it doesn't care about the extra outputs and doesn't call draw_prepare_shader_outputs().)

* llvmpipe: turn depth clears into full depth/stencil clears for d24x8 formatsRoland Scheidegger2016-01-201-11/+14
| | | | | | | | | | | | If we have a d24x8 format, there is no stencil. Therefore, we can always clear these bits too, which means this will be some kind of memset rather than read-modify-write. This is good for some 7% increase or so in gears with huge window size - seems to have a bigger effect if things aren't in caches. Of course, any real app won't spend nearly as much time comparatively in clearing depth buffer in the first place, so the speedup will be much lower. Reviewed-by: Jose Fonseca <[email protected]>
* nv50/ir: swap the least-ref'd source into src1 when both const/immIlia Mirkin2016-01-181-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The whole point of inlining sources is to reduce loads. We can end up in a situation where one value is used a lot of times, and one value is used only once per instruction. The once-per-instruction one is the one that should get inlined, but with the previous algorithm, it was given no preference. This flips things around to preferring putting less-referenced values into src1 which increases the likelihood of them being inlined. While we're at it, adjust the heuristic to not treat 0 as an immediate, as well as (effectively) check for situations where LIMMs can't be loaded. All this yields improvements on nvc0: total instructions in shared programs : 6261157 -> 6255985 (-0.08%) total gprs used in shared programs : 945082 -> 943417 (-0.18%) total local used in shared programs : 30372 -> 30288 (-0.28%) total bytes used in shared programs : 50089256 -> 50047880 (-0.08%) local gpr inst bytes helped 21 822 3332 3332 hurt 0 278 565 565 And more importantly avoids generating really bad code with SSBOs, where we end up checking a lot of different values (usually immediates) against the length. On nv50 we get comparable results, and even improve packing (bytes went down more than instructions): total instructions in shared programs : 6346564 -> 6341277 (-0.08%) total gprs used in shared programs : 728719 -> 725131 (-0.49%) total local used in shared programs : 3552 -> 3552 (0.00%) total bytes used in shared programs : 43995688 -> 43932928 (-0.14%) local gpr inst bytes helped 0 1380 3252 3774 hurt 0 287 1710 1365 Signed-off-by: Ilia Mirkin <[email protected]>

* llvmpipe: ditch additional ref counting for vertex/geometry sampler viewsRoland Scheidegger2016-01-154-46/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | The cleaning up was quite a performance hog (making pipe_resource_reference the number two in profilers on the vertex path, and 3rd overall, with its cousin pipe_reference_described not far behind) if there were lots of tiny draw calls (ipers). Now the reason was really that it was blindly calling this for all potential shader views (so 32 each for vs and gs) even though the app never touched a single one which could have been fixed, however I can't come up with a good reason why we refcount these. We've got references, of course, in the sampler views, which should be quite sufficient as we do all vertex and geometry shader execution fully synchronous. (Calling prepare_shader_sampling for all draw calls even if there were no changes looks quite suboptimal too, but generally we don't really expect vs/gs shader sampling to be used much with llvmpipe, and there's even an early exit if there aren't any views to avoid the "null loop" albeit it's now no longer always trying to loop through all 32 slots. Maybe improve another time...). Of course, if we manage to make vertex loads run asynchronously some day, we need references again, but adding that back would be the least of the problems... Also only set LP_NEW_SAMPLER_VIEW for fragment sampler views. Nothing on the vertex side depends on it (I suppose we'd really wanted a separate flag in any case). (Good for a 3% improvement or so in ipers under the right conditions.) Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: fix "leaking" texturesRoland Scheidegger2016-01-152-2/+9
| | | | | | | | | | | | | | | | | | | | | This was not really a leak per se, but we were referencing the textures for longer than intended. If textures were set via llvmpipe_set_sampler_views() (for fs) and then picked up by lp_setup_set_fragment_sampler_views(), they were referenced in the setup state. However, the only way to unreference them was by replacing them with another texture, and not when the texture slot was replaced with a NULL sampler view. (They were then further also referenced by the scene too which might have additional minor side effects as we limit the memory size which is allowed to be referenced by a scene in a rather crude way.) Only setup destruction (at context destruction time) then finally would get rid of the references. Fix this by noting the number of textures the last time, and unreference things if the new view is NULL (avoiding having to unreference things always up to PIPE_MAX_SHADER_SAMPLER_VIEWS which would also have worked).

* nvc0/ir: be careful about propagating very large offsets into const loadIlia Mirkin2016-01-144-1/+19
| | | | | | | | | | | | | Indirect constbuf indexing works by using very large offsets. However if an indirect constbuf index load is const-propagated, it becomes a very large const offset. Take that into account when legalizing the SSA by moving the high parts of that offset into the file index. Also disallow very large (or small) indices on most other instructions.
