My main desktop machine at home is a PowerMac G5 (Dual PPC970,
PowerMac7,2), so it gets lots of daily use for audio, video, and web
browsing. The graphic card is:
0000:f0:10.0 VGA compatible controller: NVIDIA Corporation NV34 [GeForce FX 5200 Ultra] (rev a1)
I am not using the Debian kernel, but rather the latest kernel.org
mainline kernel (currently 5.15.0-rc5). Perhaps my feedback is useful
anyway.
Until now I have been using 4K pages with ppc64, but today I recompiled
for 64K pages. With 4K pages I have not encountered any graphic problems
(except for a possible memory leak I recently reported [0]).
After switching to 64K pages, things seem to run well at first. I could
watch videos, browse the web, and perform typical X.org
activity. However, when I closed my PDF viewer (evince), the X
background changed to a bizarre pattern that also included the PDF
screen (even though I had already closed the PDF viewer). Oddly enough,
about a minute later, the background magically restored itself. In the
kernel logs I see lots of error messages (posted at the end of this
email).
With 4K pages I do not see any error messages, even after multiple days
of continuous heavy graphic use. I don't mind running test kernels on my
machine if it will help.
