Subject: radeonsi: Separate states for samplers and sampler views.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=23e4fe2a5310021dc522465cd9d0939117e2b641;p=mesa.git

radeonsi: Separate states for samplers and sampler views.

And reset nregs on updates. Prevents eventual assertion failure.
