Subject: radeonsi: remove a workaround for inexact *8_SNORM blits
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b05b8587ae6711a8790d4a4f5956995577184e00;p=mesa.git

radeonsi: remove a workaround for inexact *8_SNORM blits

All tests pass on Fiji now. This prevents DCC disablement due to
incompatible DCC formats due to the fallback.
