00:51 <mescalin> hi. is anybody online who knows (or might intuit) why grub boots on Snapdragon 850 ARM64 and SnapDragon 7c Kryo 468, but just one of them gets past "Graphical install" into a Linux Distro Installer? Or how to test whether the problem is in fact another hardware component, like the screen?

05:00 <travmurav[m]> mescalin: grub uses EFI "drivers" from the preinstalled firmware and thus platform-agnostic but Linux uses it's own set of drivers. I'd guess that you tried that debian installer and to my knowledge, it doesn't support 7c boards. (afaiu It has a kernel, hacked to barely boot with acpi from the firmware so one can install the system with the DT for a specific board, as traditionally done for qcom devices in Linux)

05:02 <travmurav[m]> mescalin: So, usually the kernel would need to have support for the platform (i.e. 7c) and the specific device you have, and then have it properly enabled so you can use it

15:42 <ardb> i am seeing lots of these errors, and a black screen when attempting to upgrade my c630 yoga to v5.19

15:42 <ardb> [drm:ti_sn_bridge_probe [ti_sn65dsi86]] *ERROR* failed to create panel bridge

15:43 <ardb> anyone have any clues?

15:44 <qzed> very broadly: I'd guess dp-aux-bus issues

15:45 <ardb> i imagine enabling CONFIG_DRM_PANEL_EDP might help as well - lemme try that first :-)

15:54 <ardb> ok that worked ...

15:57 <ardb> what about audio - any c630 users here with working sound?

16:09 <steev> ardb: for me audio worked with 5.19, but breaks in 6.0, but working again in -next

16:09 <ardb> weird

16:10 <ardb> it doesn't work for me on v5.14 either

16:10 <steev> i haven't used 5.14 in ages :)

16:10 <ardb> guess it might be a firmware issue

16:10 <steev> do you have the ucm confs?

16:11 <steev> https://github.com/alsa-project/alsa-ucm-conf - the c630 stuff only finally went in 16 days ago

16:11 <steev> it's 2 patches

16:52 <ardb> steev: cheers let me try that

17:00 <ardb> steev: no still only dummy output unfortunately

17:00 <ardb> lots of occurrences of

17:00 <ardb> [ 5.832875] MultiMedia1: ASoC: no backend DAIs enabled for MultiMedia1

17:00 <ardb> [ 5.832891] MultiMedia1: ASoC: dpcm_fe_dai_prepare() failed (-22)

17:01 <ardb> does this look normal to you?

17:01 <ardb> https://www.irccloud.com/pastebin/U6exodOs/

17:02 <steev> the second part looks normal, the first part, no

17:14 <steev> fwiw, when it's working normally it should look something like

17:15 <steev> https://paste.debian.net/1255738/

17:32 <ardb> cheers

17:34 <ardb> i am not seeing 'wcd934x-slim 217:250:1:0: type registers are deprecated; use config registers instead'

17:59 <steev> that might be new for 6

20:57 <ardb> steev: it's working now after a reboot
