Subject: radeonsi: move scratch reloc state setup
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dc394136404eafec689874934db0198be6182c59;p=mesa.git

radeonsi: move scratch reloc state setup

- move it to its own function
- do it after all states are emitted
- bump SI_MAX_DRAW_CS_DWORDS
