Update of /cvsroot/linux-vax/kernel-2.4/drivers/video
In directory sc8-pr-cvs1:/tmp/cvs-serv12950
Modified Files:
vmonofb.c
Log Message:
vmonofb changes:
- change line_length from 1280/8 to 1024/8
- add (red,green,blue).length which i guess are used when userspace modifies the palette
- when loading the ramdac, get the intensity value from a weighted r/g/b sum
- when loading cmap data, don't load a 0 into the data reg first (or you'll end up with a mostly empty-colormap)
- fbgen_get_var(&the_fb_info.gen.info.var) instead of &disp.var. this is "wrong" but it seems to work better
- init the_fb_info.gen.fbhw _before_ trying to use it
i'm not sure how correct these changes are.
