<dos1> is there some kind of guide on how to provide useful logs in case of gpu hangs?
<mntmn> you can enable sort of a core dump in etnaviv
<mntmn> i think it's some drm debug sysfs thing? forgot the details atm
<mntmn> drm.debug=0x06 or similar boot option
<mntmn> ah right you need to enable devcoredump somehow
<marex> dos1: on which GPU / SoC ?
<dos1> marex: GC7000L / imx8mq
<marex> ah ok, mntmn should be able to help you
<mntmn> i'm on vacation so i don't have all of my notes with me, esp. not the part on how to enable the devcoredump. afaik it was an udev rule
<austriancoder> mntmn: it is an udev rule - correct. All can be found in the etna-gpu-tools repo
<austriancoder> make install on the target and you are ready to go
<mntmn> ah perfect
<dos1> awesome, thanks!
<dos1> (and enjoy the vacation :))
