* 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). Found by code inspection, no test... v2: rename var Reviewed-by: Jose Fonseca <[email protected]>
* nv50/ir: rebase indirect temp arrays to 0, so that we use less lmem spaceIlia Mirkin2016-01-141-14/+44
| | | | | | | | | | | | | Reduces local memory usage in a lot of Metro 2033 Redux and a few KSP shaders: total local used in shared programs : 54116 -> 30372 (-43.88%) Probably modest advantage to execution, but it's an imporant prerequisite to dropping some of the TGSI optimizations done by the state tracker.

* nv50/ir: only use FILE_LOCAL_MEMORY for temp arrays that use indirectionIlia Mirkin2016-01-141-15/+50
| | | | | | | | | | | | | | | | | | | Previously we were treating any indirect temp array usage to mean that everything should end up in lmem. The MemoryOpt pass would clean a lot of that up later, but in the meanwhile we would lose a lot of opportunity for optimization. This helps a lot of Metro 2033 Redux and a handful of KSP shaders: total instructions in shared programs : 6288373 -> 6261517 (-0.43%) total gprs used in shared programs : 944051 -> 945131 (0.11%) total local used in shared programs : 54116 -> 54116 (0.00%) A typical case is for register usage to double and for instructions to halve. A future commit can also optimize local memory usage size to be reduced with better packing. Signed-off-by: Ilia Mirkin <[email protected]>
* 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. This fixes regressions in ubo_array_indexing/*-two-arrays piglit tests. Fixes: abd326e81b (nv50/ir: propagate indirect loads into instructions) Signed-off-by: Ilia Mirkin <[email protected]>

* llvmpipe: avoid most 64 bit math in rasterizationRoland Scheidegger2016-01-132-65/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trick here is to recognize that in the c + n * dcdx calculations, not only can the lower FIXED_ORDER bits not change (as the dcdx values have those all zero) but that this means the sign bit of the calculations cannot be different as well, that is sign(c + n*dcdx) == sign((c >> FIXED_ORDER) + n*(dcdx >> FIXED_ORDER)). That shaves off more than enough bits to never require 64bit masks. A shifted plane c value could still easily exceed 32 bits, however since we throw out planes which are trivial accept even before binning (and similarly don't even get to see tris for which there was a trivial reject plane)) this is never a problem. The idea isnt't all that revolutionary, in fact something similar was tried ages ago (9773722c2b09d5f0615a47cecf4347859474dc56) back when the values were only 32 bit anyway. I believe now it didn't quite work then because the adjustment needed for testing trivial reject / partial masks wasn't handled correctly. This still keeps the separate 32/64 bit paths for now, as the 32 bit one still looks minimally simpler (and also because if we'd pass in dcdx/dcdy/eo unscaled from setup which would be a good reason to ditch the 32 bit path, we'd need to change the special-purpose rasterization functions for small tris). This passes piglit triangle-rasterization (-fbo -auto -max_size -subpixelbits 8) and triangle-rasterization-overdraw (with some hacks to make it work correctly with large sizes) easily (full piglit as well of course, but most tests wouldn't use triangles large enough to be affected, that is tris with a bounding box over 128x128). The profiler says indeed time spent in rast_tri functions is reduced substantially, BUT of course only if the tris are large. I measured a 3% improvement in mesa gloss demo when supersized to twice the screen size... Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | | This is quite a few less instructions, albeit still do the 2 64bit muls with scalar c code (they'd need way more shuffles, plus fixup for the signed mul so it totally doesn't seem worth it - x86 can do 32x32->64bit signed scalar muls natively just fine after all (even on 32bit). (This still doesn't have a very measurable performance impact in reality, although profiler seems to say time spent in setup indeed has gone down by 10% or so overall.
