Henrik RydgårdandClaude Opus 5.5 a9c782bfcf SoftGPU: Recompute the raster state after a JIT cache clear
A code space clear frees the functions the current state points to, but
the state was kept as long as the GE registers didn't change. Track the
clear generations and recompute, also when a compile during the state
computation clears the caches.

Also skip the binner flush for compiles on builds without the software
JIT, where Compile() does nothing.

Henrik Rydgård 10f93875c6 Fix the semantics of DenseHashMap to be consistent even when inserting nulls 2023-09-11 12:07:18 +02:00
Unknown W. Brackets cd3fc26190 samplerjit: Prevent thread local stale cache read.
If the generation count happens to match, would still get a stale pointer
and crash.  Let's just make the generation count static so it always
increases.

Unknown W. Brackets d9522a7ac5 softgpu: Avoid clear hazard for last cached funcs. 2022-12-06 21:23:56 -08:00
Unknown W. Brackets eda3ce556e softgpu: Avoid atomic structs.
Apparently we don't link libatomic and rather than fighting that, I'll
just use thread local values.
2022-12-06 20:35:07 -08:00
Unknown W. Brackets 400f6abf9a softgpu: Optimize lookup of last jit func.
This is common (for example, maybe a pixel state is updated but sampler is
not), and reduces time spent in ComputeRasterizerState() quite a bit in
Darkstalkers, where jits are available (i.e. Intel currently.)
2022-12-06 19:16:19 -08:00
Unknown W. Brackets 87fb9eef37 softgpu: Remove std::function usage.
Wanted to avoid coupling these, but don't like the std::function
construct/destructs showing in profiles...
2022-12-06 19:15:57 -08:00
Unknown W. Brackets 778a0487cb softjit: Switch to DenseHashMap. 2022-12-02 20:59:13 -08:00
Unknown W. Brackets 4d06400548 softgpu: Fix compile hazard while running.
This prevents any clearing of cache while other threads may be using
previously cached funcs, and avoids wx exclusive hazards.
2022-11-20 12:04:02 -08:00
Unknown W. Brackets ce51942508 softgpu: Correct WX-exclusive platform hazards.
Should mainly affect BSD at this point.

Unknown W. Brackets 79b1d1d35f softgpu: Better approximate slope mip level mode (#16276)
* samplerjit: Remove unused x/y parameters.

Still need to tune the accuracy of filtering, but those were not the
right way.

* softgpu: Better approximate slope mip level mode.

This isn't exactly right, but it's closer.

* softgpu: Calculate auto from largest difference.

Direction shouldn't matter.

Unknown W. Brackets 167213c746 softgpu: Cache texture bufws at 16 bit.
Reducing the size of state a bit.
2022-09-12 21:57:00 -07:00
Unknown W. Brackets 90e009edb9 softgpu: Clamp/wrap textures at 512 pixels.
A texture larger than 512 is "valid", but simply wraps/clamps at 512.
Importantly, the texture coords are still calculated at the specified
size, which can be up to 32768.
2022-09-10 20:23:09 -07:00
Unknown W. Brackets 99d7703d33 samplerjit: Precalculate DXT1/3/5 offsets.
This improves WALL-E by 8% overall.
2022-02-05 13:04:17 -08:00
Unknown W. Brackets 1b2cf52bfe samplerjit: Fix non-shared CLUT on Linux.
Oops, good that CI will catch this now - I've broken this more than once.
2022-01-29 22:20:46 -08:00
Unknown W. Brackets d200ef40de samplerjit: Compile sampler funcs together.
We can't have the cache clear between nearest/linear, because then we'll
call a bunch of int3's.
2022-01-29 20:28:20 -08:00
Unknown W. Brackets eb70a90347 samplerjit: Avoid frac uv transfer to gen regs.
It should just stay in vec, this is more convenient anyway.
2022-01-28 23:50:54 -08:00
Unknown W. Brackets 99d6d569f0 samplerjit: Reduce transfers in nearest texel calc.
This benefits a few games, mostly where there's lots of UI or similar.
2022-01-24 21:28:04 -08:00
Unknown W. Brackets c1e657ed47 samplerjit: Better vectorize UV linear calc.
Gives about 1-2% when mips are used.
2022-01-24 20:42:07 -08:00
Unknown W. Brackets c2985bca31 softjit: Centralize some common funcs from sampler.
No need to duplicate this code.
2022-01-19 00:03:59 -08:00
Unknown W. Brackets edb79d968f softgpu: Cache CLUT params in sampler state.
And now there's no more gstate for pixel drawing or sampling.  Just a
little left in rasterization.
2022-01-15 18:09:09 -08:00
Unknown W. Brackets ad3635c82a softgpu: Move tex size to cached state. 2022-01-15 17:22:43 -08:00
Unknown W. Brackets a228b2ab6c softgpu: Use cached sampler state outside jit. 2022-01-15 15:26:26 -08:00
Unknown W. Brackets d5c5e9478e softgpu: Prepare more state per prim call. 2022-01-10 22:12:35 -08:00
Unknown W. Brackets 72aa4be879 samplerjit: Skip processing alpha if unused. 2022-01-09 12:23:55 -08:00
Unknown W. Brackets 26e7768a67 samplerjit: Remove old linear nearest paths.
We only use it for DXT now, so let's not keep the dead code around.
2022-01-02 17:28:52 -08:00
Unknown W. Brackets 7806dfddea samplerjit: Use VPGATHERDD for all types. 2022-01-02 17:19:18 -08:00
Unknown W. Brackets ce6ea8da11 samplerjit: Apply gather lookup to all CLUT4. 2022-01-02 17:19:18 -08:00
Unknown W. Brackets 22f770c828 samplerjit: Use VPGATHERDD for simple CLUT4 loads.
Planning to expand this to more paths.

Henrik Rydgård d3f0af7458 Merge pull request #15273 from unknownbrackets/softjit-bloom
Optimize software renderer handling of common bloom operations
2022-01-02 18:11:07 +01:00
Unknown W. Brackets a259761262 samplerjit: Use nearest func in fast path too.
This uses the more optimal tex funcs.
2022-01-02 08:48:16 -08:00
Unknown W. Brackets 0eec4e7e4d samplerjit: Decode colors in parallel.
Not used in a ton of games, but a decent improvement where it is used.
2022-01-02 08:27:55 -08:00
Unknown W. Brackets 7060035303 samplerjit: Implement nearest in jit.
This uses the tex func and similar within jit.
2022-01-01 16:58:05 -08:00
Unknown W. Brackets 91c9343e87 samplerjit: Refactor and reuse constant pool.
It's just here to be rip accessible, the fixed values can be output just
once.
2022-01-01 16:58:05 -08:00
Unknown W. Brackets 40240be91c samplerjit: Update nearest args, temp disable jit.
This temporarily disables jit for nearest, but refactors to use the new
arg structure.  It now matches linear.
2022-01-01 16:58:05 -08:00
Unknown W. Brackets 06e954fe2a samplerjit: Create a separate fetch func.
This allows nearest to become more similar to linear, where it applies the
texture function.
2022-01-01 16:58:04 -08:00
Unknown W. Brackets 3bc6009158 samplerjit: Refactor sampler ID calculation.
Make it the same as pixel func IDs.
2022-01-01 16:58:04 -08:00
Unknown W. Brackets 6aec68aa5c samplerjit: Correct wrong bufw at mip levels.
Oops, was always using the base bufw.
2022-01-01 16:40:02 -08:00
Unknown W. Brackets 1addf84e90 samplerjit: Use SSSE3/SSE4 in linear filtering. 2021-12-30 23:22:56 -08:00
Unknown W. Brackets 28cfbe0e5a samplerjit: Add an alternate profiling method.
This is more useful to group common operations together for profiling.
2021-12-29 07:11:39 -08:00
Unknown W. Brackets 74eb450e76 samplerjit: Move texture function into jit.
Could do this also for nearest, might end up with a third set of functions
there for a direct sample lookup (for debug funcs.)
2021-12-28 17:52:17 -08:00
Unknown W. Brackets 940e6bb1d7 samplerjit: Lookup both mip tex values. 2021-12-28 16:22:54 -08:00
Unknown W. Brackets 6b55d328e5 samplerjit: Use regcache for linear filtering.
This makes it easier to reuse for mipmap filtering.
2021-12-28 15:37:25 -08:00
Unknown W. Brackets cdf14c8579 samplerjit: Calculate mip level U/V/offsets.
Not actually doing the sampling for the second mip level in the single jit
pass yet, but close.
2021-12-28 14:12:58 -08:00
Unknown W. Brackets a4558a5736 samplerjit: Take texptr/bufw as arrays.
Prep for moving mip map sampling into linear.
2021-12-28 12:04:16 -08:00
Unknown W. Brackets 4864850b3b samplerjit: Handle mipmap width/height in S/T calc. 2021-12-28 11:29:29 -08:00
Unknown W. Brackets a84accf713 samplerjit: Move S/T calculation into jit.
Gives a pretty decent 5-10% improvement in many places.
2021-12-28 09:58:23 -08:00
Unknown W. Brackets 820361f34b samplerjit: Calculate texel byte offset as vector. 2021-12-27 11:37:32 -08:00
Unknown W. Brackets b00a66e34c samplerjit: Pass u/v coords as vector. 2021-12-27 11:37:32 -08:00
Unknown W. Brackets ce3e29a649 softjit: Fix a function arg template warning.
We're just ignoring it because it's a false positive in this case.
