Re: Power Mac G5: Attempting to get 2D acceleration with nouveau and 6800 Ultra
It looks like events have caught up with us. There’s now a 4.5.0 kernel in Debian testing and strong hints that the kernel in Stretch, when it’s released, will be based on 4.6. So your reconfigured 4.5.0-rc2 kernel is getting out-of-date.
Which raises a couple of questions:
Is there any chance that your changes could make it into an official Debian package? Seems unlikely to me — because it’s very hardware specific — but we can always hope!
Do you have plans to make a 4.6 based kernel any time?
And finally, is there a hardware solution? Is there a non-Nvidia graphics card I could purchase and install in my PowerMac-G5 that wouldn’t have the problem? I don’t need anything fancy. Just enough to run a simple 2D mate or xfce desktop.
From all of us who have benefitted from your work, a big “Thank you!”
