01:00 gekret005: agd5f: did you see my query from earlier about resource0_resize
02:36 motogangsters: https://upower.freedesktop.org/docs/Device.html it's upower interface and generated from yaml, it seems.
15:47 agd5f: emersion, not sure how to
15:47 agd5f: gekret005, I did not, can your ask again?
16:16 Remco: Does anyone have a lenovo z16? A colleague is having a lot of random crashes and the three bugs on gitlab don't really say anything useful
16:24 Venemo: Remco: I have a Z13 and I don't have any crashes
16:25 Remco: Is that the same CPU/GPU combo?
16:26 Remco: Hmm, seems to be. Which distro/kernel/mesa?
16:27 Hazematman: <Remco> "Does anyone have a lenovo z16? A..." <- I have a Lenovo T14s Gen3 AMD with the 6850U (I believe the z16 has the 6850H) and I'm experiencing random hangs out it (especially after playing a game or watching videos)
16:28 Remco: Hazematman: Any of these look familiar? => https://gitlab.freedesktop.org/drm/amd/-/issues/?search=z16
16:29 Remco: Some people are suspecting it has to do with runtime power management, but it's hard to check because of the randomness
16:30 Hazematman: Yeah when ever there is a hang or freeze, dmesg log will have messages about the ring not responding and then resetting the gpu. I also have some graphical artifacts where the display will flicker (it kind of looks like tearing but I'm not 100% sure)
16:30 Hazematman: I don't think I've saved a log though. I can somewhat reliably reproduce it if I run youtube for ~1 hour
16:32 Hazematman: I'm running fedora, and following this issue https://gitlab.freedesktop.org/drm/amd/-/issues/2068 and someone there recommend using a different kernel (specifically this one https://copr.fedorainfracloud.org/coprs/sentry/kernel-fsync/) but I haven't really had any more stability with it as far as I can tell
16:32 Remco: Yeah, all the "fixes" still do the same thing, but with different randomness it seems like
16:33 Remco: Different kernels might be stable for a few days, then crash every few hours
16:33 Remco: Disabling vaapi was also in a comment, as was runtime pm disabling. They work until they don't :(
16:34 Hazematman: The issue also mentions using ryzenadj https://gitlab.freedesktop.org/drm/amd/-/issues/2068#note_1681680 I was unable to do this on my processor. I believe the command the person posted there is specific to the H processors. Did you try that?
16:35 gekret005: agd5f: https://bpa.st/UFXDO
16:35 Remco: Hazematman: I'll ask my colleague tomorrow if I don't forget
16:36 gekret005: the stuff i said about dumping vbios made no difference its strictly a rebar issue
16:37 gekret005: i am able to swap between amdgpu and vfio whenever so thanks amd for not once again having weird reset issues
16:41 gekret005: still never see the vm uefi splash though it just starts working once windows boots
16:41 gekret005: have to install the drivers through rdp or spice
16:42 gekret005: but after that no issues
17:23 Venemo: Remco: sorry for the late reply. the Z13 has similar (but not exactly the same) hardware, most notably it has the U series CPU and it does not have a dGPU
17:23 Venemo: Remco: mine has the 6850U, and I use Fedora on it
17:26 agd5f: gekret005, you won't see the UEFI splash unless the pre-OS environment runs (i.e., the UEFI GOP driver)
17:27 Venemo: Hazematman: from your descriptions yes it does sound like a power management issue, sadly the kernel is pretty bad at that :(
17:31 Remco: Venemo: He has the one without a dGPU. We'll see whether the ryzenadj thing works
17:35 Venemo: Remco: there is a linux specific forum on lenovo's site where their linux team sometimes replies, you could try to post the issue there: https://forums.lenovo.com/t5/Linux-Operating-Systems/ct-p/lx_en or if you are convinced it's a GPU issue then you can also open an issue on AMD's bug tracker here: https://gitlab.freedesktop.org/drm/amd/-/issues
17:37 Venemo: looking at the issue linked above, assuming you have the same problem and it is fixed by changing the voltage, it does seem like a power management issue then
17:39 Venemo: we've had other bug reports in the past where linux was unable to set correct voltages to the GPU
17:39 Venemo: so this may be something similar
17:48 Remco: Venemo: Thanks for the links, I'll relay tomorrow
22:55 gekret005: agd5f: yeah that's what i meant i cant see any of the pre-os stuff before windows loads also i still dont know where this rebar issue would be tracked
