167213c746 softgpu: Cache texture bufws at 16 bit. 
Reducing the size of state a bit.

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.

df1a91ee25 samplerjit: Correct nearest negative texture clamp. 
Was not clamping to zero when negative.

3e4afe2a0c samplerjit: Avoid RCX gymanstics with BMI2. 2022-01-31 22:33:09 -08:00
Unknown W. Brackets
4cadcea6da samplerjit: Decode colors with BMI2. 
This only happens with nearest, though, so very small benefit.
 2022-01-31 22:05:34 -08:00

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

3387ab1711 samplerjit: Fix reg corruption in DXT funcs. 
We'd cache something in a reg, but it'd no longer be there.
 2022-01-29 20:29:08 -08:00
Unknown W. Brackets
5976cad797 samplerjit: Reduce register waste. 
A few registers were allocated longer than needed, which made requiring
stack more likely.
 2022-01-29 09:47:06 -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

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
733046962f samplerjit: Reuse XMM reg for sizes. 
Gives just under 1% overall improvement in games using mips.
 2022-01-24 19:01:23 -08:00
Unknown W. Brackets
d8c5c35b1a samplerjit: Optimize texenv blending a bit. 
This reduces to a single multiply, which is much faster.
 2022-01-23 11:43:34 -08:00
Unknown W. Brackets
4262e657b4 samplerjit: Oops, forgot about 64 unpack. 
Just a minor codegen tweak.  Always forget there are more of these than
pack instructions.

0425b8d630 samplerjit: Fix Linux stack corruption. 
Oops, nearest was not using the red zone correctly.

212e730e98 samplerjit: Fix some Linux register issues. 2022-01-22 00:14:15 -08:00
Unknown W. Brackets
6ec819878a samplerjit: Reduce prolog/epilog spill. 
Track reg usage so we only push/pop what we need.
 2022-01-19 00:03:59 -08:00

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
0ba2d05da5 samplerjit: Simplify AVX shift-copies. 
These have been the most common and the fallback is safe.  Let's just add
a helper.
 2022-01-17 15:15:36 -08:00

d6fa301ab1 softgpu: Track CLUTs as states for binning. 
This way we can have multiple CLUTs in process at once, which helps.
 2022-01-16 08:14:09 -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.

741a9b0a4d samplerjit: Fix DXT compilation. 2022-01-05 00:00:03 -08:00
Unknown W. Brackets
19998976c7 samplerjit: Correct linear compile failure. 
It was resetting to nullptr, because `nearest` was nullptr.
 2022-01-04 23:58:07 -08:00
Unknown W. Brackets
2aa57679fa softjit: Keep mip S/T calc in SIMD. 
This is only a tiny bit faster, though.
 2022-01-03 06:45:10 -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
5e3bef7e14 samplerjit: Avoid gather if overread could crash. 
This should be rare, but a game could easily shove a CLUT4 texture at the
end of VRAM, and then accessing the last index would segfault.
 2022-01-02 17:28:52 -08:00

22f770c828 samplerjit: Use VPGATHERDD for simple CLUT4 loads. 
Planning to expand this to more paths.

65c84d5dd5 samplerjit: Avoid a couple more copies in AVX. 
From looking at assembly, just trying to keep it small.

0eec4e7e4d samplerjit: Decode colors in parallel. 
Not used in a ton of games, but a decent improvement where it is used.

7060035303 samplerjit: Implement nearest in jit. 
This uses the tex func and similar within jit.

91c9343e87 samplerjit: Refactor and reuse constant pool. 
It's just here to be rip accessible, the fixed values can be output just
once.

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.
