freedreno/a6xx: Flush depth at the end of bypass rendering, too. (!8146) · Merge requests · Mesa / mesa

Emma Anholt requested to merge anholt/mesa:fd6-flush-sysmem into master Dec 17, 2020

We apparently don't have anything else making sure that it's flushed in between use as a render target and use as a texture source, so bypass-mode depth texture sampling could get stale data.

Fixes consistent (as far as I could see) failures in FD_MESA_DEBUG=nogmem on:

dEQP-GLES31.functional.texture.multisample.samples_*.use_texture_depth_2d
dEQP-GLES31.functional.stencil_texturing.render.depth24_stencil8_draw
