Created attachment 141148 [details] oops kernel message Booting latest amd-staging-drm-next is causing kernel OOPS. Hardware is Lenovo netbook G50-45 A6 6310 APU with R4 Mullins. Kernel booted with "amdgpu.dc=1" and "amdgpu.dpm=1". Blank eDP screen can be caused by another bug: https://bugs.freedesktop.org/show_bug.cgi?id=106940, but three is no picture on connected HDMI monitor also (opposite to the situation in mentioned bug report). Panic message, that I've got from pstore, attached.
What physical connectors are on your system?
Internal - eDP - Laptop screen. External VGA and HDMI.

The patches (all three) applies fine, but I cannot compile kernel due to: "drivers/gpu/drm/amd/amdgpu/kv_dpm.c: In function ‘kv_dpm_process_interrupt’: drivers/gpu/drm/amd/amdgpu/kv_dpm.c:3210:24: error: ‘handle’ undeclared (first use in this function); did you mean ‘ihandle’? kv_dpm_powergate_vce(handle, gate); ^~~~~~ ihandle drivers/gpu/drm/amd/amdgpu/kv_dpm.c:3210:24: note: each undeclared identifier is reported only once for each function it appears in drivers/gpu/drm/amd/amdgpu/kv_dpm.c:3210:32: error: ‘gate’ undeclared (first use in this function); did you mean ‘path’? kv_dpm_powergate_vce(handle, gate); ^~~~ path make[4]: *** [scripts/Makefile.build:317: drivers/gpu/drm/amd/amdgpu/kv_dpm.o] Błąd 1 make[4]: *** Oczekiwanie na niezakończone zadania...."

Created attachment 141248 [details] pstore kernel oops message with applied patches (In reply to Przemek from comment #7) > Repo is git fetched to the latest (today's). Did I miss something? > > Thanks, > Przemek. Yes I did. Fetching once again the online repo resolved the problem with compilation, but those patches didnt help with kernel oops. I have attached full pstore message log. Thanks, Przemek.
Thanks for testing the patches. Looks like there's still an issue with DC.
I appear to be experiencing the same bug. Same set of internal and external connectors. My hardware is Lenovo G75 A10-7300 [Kaveri] Kernel booted with - amdgpu.cik_support=1 - radeon.cik_support=0 - amdgpu.dc=1 - drm.debug=1 The internal (eDP) display fails to work. The VGA display doesn't work either (as expected), and I can't comment on the HDMI as I don't have an HDMI monitor. Used ssh to get in and copy the dmesg buffer. I do not have the capability to compile kernel+patches. Sorry. graaskaeg [ 1.963843] [drm] radeon kernel modesetting enabled.

Yesterday I have pulled git repo, and guess what? _No_ more kernel _oops_, both screens lights up properly (eDP and HDMI, for VGA there is still " [drm] Unsupported Connector type:5!"). I have no idea what have changed, but thank you very much! BTW. there is an error in dmesg: "[drm:dm_pp_get_static_clocks [amdgpu]] *ERROR* DM_PPLIB: invalid powerlevel state: 0!" but I think this is another story. I am closing this bug report, as RESOLVED - FIXED. Pontus Gråskæg, if kernel compiled from the latest git repo sync (git://people.freedesktop.org/~agd5f/linux) does not work for you feel free to reopen it. Thanks, Przemek.

Yeah, "Kaveri" - logical approach. Sorry.
