[Mesa-dev] [PATCH v2 3/9] radv: implement all depth/stencil resolve modes using graphics

Samuel Pitoiset samuel.pitoiset at gmail.com
Wed Jun 12 09:47:45 UTC 2019


When using graphics, the driver doesn't need to decompress HTILE
before resolving. This path currently doesn't support layers
so we have to fallback to the compute path.

v2: - use image view format
