[Mesa-dev] [PATCH 3/5] i965: Check base format to determine whether to use tiled memcpy

The tiled memcpy doesn't work for copying from RGBX to RGBA because it doesn't override the alpha component to 1.0. Commit 2cebaac479d4 added a check to disable it for RGBX formats by looking at the TexFormat. However a lot of the rest of the code base is written with the assumption that an RGBA
