From: Kevin Rogovin <kevin.rogo...@intel.com>
This patch series implements a needed workaround for Gen9 for ASTC5x5
sampler reads. The crux of the work around is to make sure that the
sampler does not read an ASTC5x5 texture and a surface with an auxilary
buffer without having a texture cache invalidate and command streamer
stall between such accesses.
With this patch series applied to the (current) master branch of mesa,
carchase works on my SKL GT4.
v3:
Rebase against current master; this required an additional
patch to restore the disable_aux argument to
intel_miptree_prepare_texture().
Minor polishing of patches in mid-series for cleanness.
v2:
Rename workaround functions from brw_ to gen9_
(suggested/requested by Topi Pohjolainen).
Place texture resolve to avoid using auxilary surface
when ASTC5x5 is detected in brw_predraw_resolve_inputs()
instead of another dedicated function; doing so allows
one to avoid walking the textures again.
(suggested/requested by Topi Pohjolainen).
Emit command streamer stall in addition to texture
invalidate.
(original short-coming caught by Jason Ekstrand)
Place workaround function in (new) dedicated file.
Minor patch re-ordering to accomodate changes.
