We don't use on-chip GS, so it's not required to reserve CU1 for ES.
Why is a deadlock not possible with an off-chip GS ring?
It's about LDS.

On-chip GS uses LDS instead of the rings, which can cause a PS
deadlock just like LS.
We could allow all shaders to run on all CUs if the kernel programmed
SPI_RESOURCE_RESERVE*_CU0 and *_CU1 slightly differently. Those
registers allow reserving a half of LDS for certain stages. For
example, reserving it for PS would mean that PS could use all of CU0
LDS, but LS could only use a half. This is best for chips with only a
few CUs.
Thanks, I got it now. Patch 3 also gets my R-b
