fbdev: add drawing functions for framebuffers in system RAM2007-05-08T18:15:30+00:00Antonino A. Daplasadaplas@gmail.com2007-05-08T07:38:57+00:00urn:sha1:68648ed1f58d98b8e8d994022e5e25331fbfe42a
The generic drawing functions (cfbimgblt, cfbcopyarea, cfbfillrect) assume
that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb,
arcfb, and vfb) where the framebuffer is allocated from system RAM (via
vmalloc). Using _raw_read/write and family for these drivers (as used in
the cfb* functions) is illegal, especially in other platforms.
Create 3 new drawing functions, based almost entirely from the original
except that the framebuffer memory is assumed to be in system RAM.
These are named as sysimgblt, syscopyarea, and sysfillrect.
