tjaaltonlotuspsychje: i was wrong, the commit was in 4.19 already08:32
tjaaltonmaybe try blacklisting the module and try 5.3rc, it should flicker again08:33
tjaaltonI don't think the bug in i915 which causes the flicker has been fixed yet08:46
lotuspsychjetjaalton: but the module was my eth card, would that still be valid then?08:54
lotuspsychjemy wifi is that iwlwifi08:55
lotuspsychjetjaalton: whats weird, that thread i found was mentioning same intel wifi, but the commit is about r816908:56
tjaaltonlotuspsychje: it's loaded, and the commit means that it's no longer blocking the cpu/gpu to enter lower power state09:05
tjaaltonwhich then triggers the bug in i91509:05
tjaaltonit all makes sense09:05
tjaaltonjust blacklist r8169 (or unload it) and test on 5.3rc09:05
lotuspsychjeallrighty09:05
lotuspsychjebut 5.3 was not flickering right09:06
lotuspsychjeonly 5.0 flickering09:07
tjaaltonbecause it had another commit for r816909:07
lotuspsychjeah09:07
tjaalton62b1b3b3b6d3ef3 r8169: don't activate ASPM in chip if OS can't control ASPM09:08
tjaaltonwhich I believe kinda reverts the older commit09:08
lotuspsychjeok, blacklist added, lets reboot09:08
tjaaltonin the sense that it would no longer use lower cstates09:08
lotuspsychjetjaalton: you need my dmesg now with the blacklist?09:12
tjaaltonno09:12
tjaaltondoes it flicker?09:12
lotuspsychje5.3 was not flickering09:12

lotuspsychjer8169 0000:01:00.1: can't disable ASPM; OS doesn't have ASPM control09:18
tjaaltonso it's loaded anyway?09:20

lotuspsychjetjaalton: http://dpaste.com/2JBCR5F09:20
lotuspsychjermmod: ERROR: could not remove module r8169: Operation not permitted09:21
tjaaltonhow about sudo -s first..09:21
lotuspsychjereboot again?09:22
tjaaltonwhat?09:23
tjaaltonhow did you blacklist it?09:23
tjaalton'sudo rmmod r8169'09:23
lotuspsychjeadded to /etc/modprobe.d/blacklist09:23
tjaaltondoes it work?09:23
lotuspsychjermmod: ERROR: Module r8169 is not currently loaded09:24
tjaaltoncool, does it flicker after suspend/resume09:24
lotuspsychjelets try09:24
lotuspsychjeno, Fn keys brightness also work09:25
tjaaltonwhat's that got do to with this? :)09:26
lotuspsychjetjaalton: well the Fn keys have influence on the flickering09:26
lotuspsychjemaking it flicker more09:26
lotuspsychjeso im alwyas testing too09:26

tjaaltonsudo cat /sys/kernel/debug/dri/0/i915_dmc_info09:27
lotuspsychjehttp://dpaste.com/16GYRN809:28
tjaaltonsounds like some other device is now blocking lower power state09:28
tjaaltonif r8169 is not loaded09:29
tjaaltonfun09:29
lotuspsychjeyikes09:29
tjaaltonanyway, we should get 62b1b3b3b6d3ef3 in 5.009:29
lotuspsychjetjaalton: i dont need to test this blacklist on 5.0?09:30
tjaaltonit wouldn't have any effect09:30
lotuspsychjekk09:30
tjaaltonthing is though, that it's kinda hard to debug the actual bug in i915 because their code is now based on 5.3 where the bug doesn't happen09:31
tjaaltonisn't triggered I mean09:31
lotuspsychjeah09:31
lotuspsychjetjaalton: if it can help, these are the kernels we all tested: http://dpaste.com/2T98DVQ09:34

tjaaltonlotuspsychje: no need to test anything, since I know what's going on13:50
tjaaltonlotuspsychje: 5.2 has this: b75bb8a5b755d0c r8169: disable ASPM again14:04
tjaaltonthat's why it doesn't flicker14:05
tjaaltonalso, it explains why my builds with smaller config didn't flicker14:05
lotuspsychjetjaalton: allright, thank you for all your work, time & effort in this bug14:57
