I've been told we're pretty much on our own. I had to press my luck with this to get the info on a host data error interrupt/reset, which was mentioned in the documentation but not offered. I guess we could pester again, but I really don't want to burn bridges- I want to see the Radeon 8500 supported as open source, etc. If this works out, great. It's still going to have stalls. If it doesn't work or isn't safe, we've still got some stuff in hand to lower the amount of stall time that we've discussed on IRC (Which is to set the chip to interrupt on the VBLANK and when it hits the midpoint scanline- that's something like 120-160hz which is probably much more than the chip could handle in rendering performance. I'm still voting for that one because it gives cleaner error recovery...) -- Frank Earl _______________________________________________________________ Have big pipes?
