From 4531f0ffcec591e3853e78ce58f5d83cf276fb0d Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 2 Mar 2020 13:54:22 -0600 Subject: [PATCH] iris: Allow HiZ on blit sources Ever since 95cc5438ebf, BLORP has been able to read from HiZ-compressed depth buffers as long as the sampler supports HiZ. This just makes iris stop doing the unneeded resolve.
