Subject: i965: Add debug to INTEL_DEBUG=blorp describing hiz/blit/clear ops.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a2ca98b211138e2e4ac906cacefe02b4e064e01c;p=mesa.git

i965: Add debug to INTEL_DEBUG=blorp describing hiz/blit/clear ops.

I think we've all added instrumentation at one point or another to see
what's being called in blorp.  Now you can quickly get output like:

Testing glCopyPixels(depth).
intel_hiz_exec depth clear to mt 0x16d9160 level 0 layer 0
intel_hiz_exec depth resolve to mt 0x16d9160 level 0 layer 0
intel_hiz_exec hiz ambiguate to mt 0x16d9160 level 0 layer 0
intel_hiz_exec depth resolve to mt 0x16d9160 level 0 layer 0
