21:11 <urja> hey umm... anyone booted a 5.15-rc2 (or rc1 for for that matter, but rc2 is what I umm... tested...) on a veyron?

21:12 <urja> Just wondering whether me/my autobuilder f'ed up or what because my testing build just ... blank screens (backlight is on, nothing comes on screen... for more I'd need to wire up serial or smth ffs)

21:19 <urja> Note to self: autobuilder needs boot tester ... and i would have a spare C201 MB now; the one thing i dont know is ... how would i test that the display actually gets ... content and all (without like, looking at one)

21:35 <urja> (i mean, i guess getting a dmesg that says its doing it (even if nothing is attached to show it) would be better than nothing... most of these failures are something ... before the display gets driven)

21:44 <robclark> urja: drive-by suggestion if you are using olddefconfig, you may need to enable CONFIG_DRM_PANEL_EDP

21:48 <urja> am using olddefconfig... checking ...

21:49 <robclark> there was some discussion about it at https://lore.kernel.org/all/CAD=FV=XzPVda==+hkJ8ZJNXz3sT=V+8y4gbsbUik4k3Om_cGvQ@mail.gmail.com/ if you are curious.. I assume veyron is using an eDP panel so might be effected

21:54 <urja> hmmm.... can't find that conig symbol (the simple one yep is there and enabled, but can't find anything *_EDP)

21:54 <urja> *config

21:54 <urja> i'll git log the area a bit...

21:55 <robclark> it's *possible* that is only on linux-next at this point? Not sure off the top of my head, if it isn't in linus's tree yet, keep that new config option in mind for 5.16 ;-)

21:56 <robclark> as it will defn matter for everything that has panel-simple eDP panel

22:03 <urja> yeah thanks for the heads up :P ... but yeah i'll leave figuring out what's wrong now to tomorrow... it late.

22:04 <robclark> np.. anything else that is more veyron specific, I probably don't have much of an idea on.. but I knew that kconfig split is coming down the pipe because it effects a bunch of snapdragon things
