e93c709f5c sofjit: Correctly poison memory. 
Noticed this wasn't breakpoints when reviewing some assembly output.

745c35f320 softjit: Small bloom optimization. 
Another common case, src*dst + dst*0.  Can skip the add.

355bad666c softjit: Optimize common case bloom blending. 
Bloom often uses fixed ONE + ONE, which is a lot less work for us.  And
bloom often runs over and over again on pixels, so saving work is good.

496545e55c softgpu: Add code for tracking GPU writes. 
Unfortunately, it has a pretty noticeable speed impact, even at the basic
"assume everything's written" level.  Compiled off by default, but at
least it's there.

Doesn't account for tests (i.e. alpha test skipping write) so still not
perfectly accurate.

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

025ac99f2f softgpu: Reduce interpolation if not needed. 
About 3% gain in some areas.

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.

06e954fe2a samplerjit: Create a separate fetch func. 
This allows nearest to become more similar to linear, where it applies the
texture function.

3bc6009158 samplerjit: Refactor sampler ID calculation. 
Make it the same as pixel func IDs.

d41e42d247 softgpu: Correct off-by-one scissor mask. 
Fixes Brave Story in the software renderer.  Was overwriting display list
data in the stride gap.
 2022-01-01 16:42:36 -08:00
Unknown W. Brackets
b35ca3d472 softgpu: Cleanup min/max tri range handling. 
The previous looked like it had off by one errors.  This is simpler.

e82fd3bd33 GPU: Avoid spline crashes on bad data. 
If we get 0 prims, we can generate confusing index bounds and go out of
bounds.  Similarly, if we get a crazy number of control points and fail to
allocate, we can crash.

12405709f0 softgpu: Skip processing scissored triangles. 
If only one side was scissored (common), we might even put it on a thread,
which ended up as a lot of overhead.  Gives 3-4% improvement in some
places.

6aec68aa5c samplerjit: Correct wrong bufw at mip levels. 
Oops, was always using the base bufw.

8c31f1bb38 softjit: Fix regcache error when clearing. 
Happens for non-through clears.

8ea67b571b samplerjit: Tiny dependency optimizations. 
This had a small but measureable impact (~0.3%.)

fc3688d273 samplerjit: Small AVX optimization to modulate. 
Only gives about 0.5% but it's still something.

33e9841a4a softgpu: Skip zero size triangles. 
These were drawing before, incorrectly, which caused artifacts.
Noticeable in Blade Dancer.

147b81d6f7 x64jit: Add AVX/AVX2 encodings. 
Also fix the FMA double ones, which were passing W wrongly.

4bd94a4e5e samplerjit: Pass funcs as an argument. 
Seeing computing the ID in some profiles, so want to avoid computing per
thread/invocation.

28cfbe0e5a samplerjit: Add an alternate profiling method. 
This is more useful to group common operations together for profiling.

3aedea89eb samplerjit: Correct level lookup offset. 2021-12-29 07:09:36 -08:00

bf06342f9d samplerjit: Minor SSE4 optimizations. 
These seem to be a bit faster.

631706a8ba samplerjit: Set stackArgPos_ early. 
Unfortunately, this has to match the value set lower...

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.)

940e6bb1d7 samplerjit: Lookup both mip tex values. 2021-12-28 16:22:54 -08:00

6b55d328e5 samplerjit: Use regcache for linear filtering. 
This makes it easier to reuse for mipmap filtering.

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.

a84accf713 samplerjit: Move S/T calculation into jit. 
Gives a pretty decent 5-10% improvement in many places.

476dfdf731 samplerjit: Add more bits for S/T, skip multiply. 
For now, we're not using those other bits yet.

9cc0883d53 softgpu: Correct non-SSE T clamp. 2021-12-27 15:31:37 -08:00
Unknown W. Brackets
39d5b1c221 softgpu: Reduce mipmap fraction to 4 bits. 
For CONST (and SLOPE with flat w), this produces accurate values.
SLOPE is still wrong in its handling of w, and AUTO seems to calculate
using a different and less accurate ramp.  But they both produce values
with 16 steps, in any case.

d6b6ef4cb1 softgpu: Correct nearest filtering too. 
Turns out to have the same behavior as linear, when it comes to the
subpixel offset.
 2021-12-27 11:37:33 -08:00
Unknown W. Brackets
1dfaea9062 softgpu: Remove no longer possible report. 
Also, it's known how this behaves, now.
 2021-12-27 11:37:33 -08:00
Unknown W. Brackets
75f105f84b softgpu: Make linear filtering more accurate. 
This matches tests for various u/v offsets and x/y subpixel offsets.
Mipmaps are probably still wrong.
