Re: Fwd: NetBSD driver for Cirrus Logic EP93xx graphics engine - EPFB
thanks for your mail and sorry about the addresses, the GMX address should do
for now. (I wonder where the raphael.g-system.at address is actually listed,
probably the port-arm list subscription - I need to change that some day).
Regarding the X server support, right now I'm directly using the epfb device
through ioctl (see epio.h) with custom software. However, I think that X11
support would be beneficial to be able to run X11 apps, but I have not started
any work in this respect, yet. Please let me know when/if you start working on
Right now I'm sticking to NetBSD 4.0 release, any (future) patches, etc. will
most likely work for this release, then. When I switch versions I will note it
on the webpage. A few weeks ago I tested to compile it against CVS HEAD which
worked, too (use the diff for the machdep file), but I didn't run CVS HEAD so I
don't know if the compiled kernel worked.
I'm glad the files/patches are of use to others, too.
