Steam main window
Steam is no longer usable with mesa git. I suspect this is SI (Radeon HD 79=
70)
specific though. Confirmed bad commit by reverting it.=20
2b8b9a56efc24cc0f27469bf1532c288cdca2076 is the first bad commit

radeonsi: move PSIZE and CLIPDIST unique IO indices after GENERIC
Heaven LDS usage for LS+HS is below. The masks are "outputs_writte=
n"
for LS and HS. Note that 32K is the maximum size.
Before:
heaven_x64: ls=3D1f1 tcs=3D1f1, lds=3D32K
heaven_x64: ls=3D31 tcs=3D31, lds=3D24K
heaven_x64: ls=3D71 tcs=3D71, lds=3D28K
After:
heaven_x64: ls=3D3f tcs=3D3f, lds=3D24K
heaven_x64: ls=3D7 tcs=3D7, lds=3D13K
heaven_x64: ls=3Df tcs=3Df, lds=3D17K
All other apps have a similar decrease in LDS usage, because
the "outputs_written" masks are similar. Also, most apps don'=
t write
POSITION in these shader stages, so there is room for improvement.
(tight per-component input/output packing might help even more)
It's unknown whether this improves performance.
