--- Comment #10 from Iago Toral <ito...@igalia.com> --- (In reply to Iago Toral from comment #9) > Jason, piglit tests hit cases where they attempt to convert GL format and > data type combinations that do not match any of the existing mesa formats. > > For example GL_RGB + GL_UNSIGNED_BYTE_2_3_3_REV (BBGG GRRR). The Only mesa > format of this kind is MESA_FORMAT_B2G3R3_UNORM (RRRG GGBB). > > This means that we don't have pack and unpack functions for these types, > which we need to use a master conversion function. I think the natural thing > to do would be to add new mesa_format types for these, together with their > format_pack.c and format_unpack.c functions (which should be auto-generated > too). I suppose it is okay to add new mesa_format enums, right? BTW, as an added bonus, with this approach we will speed up conversion for some of these types too. For example, the way Mesa currently handles GL_UNSIGNED_BYTE_2_3_3_REV to GL_RGBA UBYTE involves two conversions (2_3_3_REV -> RGBA FLOAT -> RGBA_UBYTE), while we would be able to do that in one go via the auto-generated unpack function. -- You are receiving this mail because: You are the QA Contact for the bug.
