Yes. Panfrost in this kernel was in its early stage. Not stable for a good desktop experience, unfortunately.
and I found out that panfrost for h6 t720 is not stable except I did this:
cd /sys/devices/platform/soc/1800000.gpu/devfreq/1800000.gpu/
echo userspace > governor
echo 756000000 > max_freq
echo 756000000 > min_freq
Did you do that in your panfrost testing, too?
No, i did not. Please, report your findings. Thanks.
I got that trick from https://forum.armbian.com/topic/12516-unable-to-make-panfrost-work-on-h6/page/4/
and I think you are so lucky, if I did not set those settings when I run glmark2, the X will die in a very short time even I send a reboot from ssh to the Linux, the system still hangs
And for your minimal image, I tried once, I need to rename /dev/dri/card1 to be other name else so that the X can show up, or x will fail with an error
Fatal server error:
[ 23.406] (EE) AddScreen/ScreenInit failed for driver 0
I was very curious that what exactly os image you were testing the H6 wth panfrost enabled, it is so unique that you don't need those tricks above(setting the freqs)
If it is convenient for you, would you like to upload a working os image included your kernel?
best regards
hi avafinger
Did you build the mesa and libdrm manually, not using them from 18.04 repo?
thanks
