From: Nicolai Hähnle Date: Thu, 23 Nov 2017 09:29:49 +0000 (+0100) Subject: radeonsi: always place sparse buffers in VRAM X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=20ccb51ffcc46a68ab0eb82a43ed55a1e1952850;p=mesa.git radeonsi: always place sparse buffers in VRAM Together with "radeonsi: fix the R600_RESOURCE_FLAG_UNMAPPABLE check", this ensures that sparse buffers are placed in VRAM. Noticed by an assertion that started triggering with commit d4fac1e1d7 ("gallium/radeon: enable suballocations for VRAM with no CPU access") Fixes KHR-GL45.sparse_buffer_tests.BufferStorageTest in debug builds.
