Hi,
How should the "format" of a DRI2 buffer be determined?
http://www.x.org/releases/current/doc/dri2proto/dri2proto.txt
DRI2ATTACH_FORMAT { attachment: CARD32
format: CARD32 }
The DRI2ATTACH_FORMAT describes an attachment and the associated
format. 'attachment' describes the attachment point for the buffer,
'format' describes an opaque, device-dependent format for the buffer.
xorg-server-1.7.7/hw/xfree86/dri2/dri2ext.c
If it's opaque, how does a user or library know what bytes are red/green/blue
so that you can draw a line in the right colour?
