The bad = Starting with DRI3 (which is default) I still get trashed

I use Fluxbox window manager, which does not use compositing -
IIRC this has historically shown some ddx DRI2/3 issue that wasn't
visible to those testing with compositing (but then the full screen
case may avoid compositing anyway depending on settings).
You may be running into a DDX driver issue fixed by
https://patchwork.freedesktop.org/patch/118514/ .
Yes, that was it, OK with that patch.
Though "OK", sub-optimal loosing pageflip on tonga, as a vsync test
fails top 5% of screen unless I force GPU perf high.
This reason for this is that in case of single gpu, I have to recalculate
its handle and get a pixmap from that buffer for each frame. This calulation
is avoided due to the presence of a linear buffer in case of different gpu.
OK, possibly I misunderstand your answer, but I don't think any extra
calculation is the issue, it's purely that I loose pageflip. By which
I mean without your patches I can reproduce with R600_DEBUG=notiling.
Powerplay is not giving me enough on auto, but TBH I may not like it
if I had to be permanently higher/hotter to handle just one case.
Maybe the timing/efficiency of display copies is an issue - I don't know.

Not related to this patch directly of course, but I am a bit surprised
that on auto powerplay the tonga is too slow to make 60Hz.
Tested with CPU forced high, so it's not CPU freq.
