Re: [Mesa3d-dev] RFC: allow resource_copy_region between different (yet compatabile) formats

[Luca B. <lu...@lu...>]

Yes, if x8 is interpreted as "writes can write arbitrary data, reads
must return 1" (as you said), then this is not necessary in
resource_copy_region even if A8 -> X8 becomes supported.

You are right that format conversions would probably be better added
as a separate function (if at all), in addition to the
"reinterpret_cast" mechanism you proposed to add.
