Well, the good news are that, with your help, I got it working. Turns out
it was not working ealier because:
a) the struct in bmaster.c file is specific to the example,
in particular, the name of the fields is way off.
b) VIPH is only for transfers to/from VIP

Actually Manuel, I'm working f
Hello again.
First of all, I think that Jouko success putting to work the old mach64
branch points that there must be some difference in the 2D card
initialization. I'll try to look deeper in the 2D driver issues.
The second point is that I've migrated the mach64 changes to a fresh DRI

The agp aperture is implemented on the motherboard, nothing to do with which
video card you plug in. Some newer chipsets appa

Userspace programs always deal in virtual addresses. You need to map the
section of agp space
I got an Acer Travelmate laptop this week and would like to see 3d
acceleration on it, so i tried tweaking with the mach64 branch.
There was a minor issue with up() and down() which caused a kernel oops.
After fixing that, I commented out some code in mach64_do_dma_init() which
doesn't seem to w
