The driver works now quite well with my hw. Check the ctfb_README for limits and features. What about a merge with the old chipsfb.o?
I'm working on my 69030 driver as a separate driver currently, because of the requirement to use memory mapped IO and avoid all fixed IO addresses, which makes it incompatible with the 65550. I did look at your driver, but I decided to base mine on the existing chipsfb.c because I needed PowerPC support, and because the coding style of your driver was quite different to existing frame buffer drivers. My priorities are: 1) Not assume any BIOS setup, as BIOS setup only occurs on x86 hosts, and only on the primary display. 2) Avoid use of the big-endian region in the chip, while still supporting big-endian hosts. This is necessary to support the twin-pipeline mode of the 69030 in future. 3) Support multiple displays. This requires use of memory mapping. - Adrian Cox, AG Electronics ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
