In addition, the non-raw variants may do some extras to guarantee ordering, which you do not need on a frame buffer.
Given this comment, should we declare the fb_() helpers in <asm-generic/io.h> or <linux/io.h>?
I still don't like the idea of having the functions in <linux/fb.h>. We have code in DRM that also accesses framebuffer memory (via memcpy_toio()). It would make sense to use the fb_() helpers, if they are tailored towards this usecase.
Best regards Thomas
So I'd go for the __raw_*() variants everywhere.
