Subject: anv: Respect ISL_SURF_USAGE_DISABLE_AUX_BIT in make_surface()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c13202af7a86976e6d0400f2cee77afcc60ea828;p=mesa.git

anv: Respect ISL_SURF_USAGE_DISABLE_AUX_BIT in make_surface()

If set, then don't make the aux surface.

Only anv_android.c used the flag, but anv_image.c fully ignored it.
