00:05 <derzahl> hows 5.15 kernel coming on the c630?

00:06 <derzahl> tried it a few weeks ago and just got a black screen shortly after boot began

02:04 <steev> works here

02:05 <steev> but i have a bunch of patches on top still

02:05 <steev> when 5.17 comes up, i'll probably drop most of them

02:06 <steev> derzahl: i pushed my 5.15 stuff earlier - one thing, you should drop the clk_ignore_unused command line parameter

02:06 <steev> [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.15.12 root=UUID=83d75c37-0ba4-4a8e-8e13-996d96bf39b1 ro pd_ignore_unused quiet splash

02:06 <derzahl> hm. wonder why my screen just goes black

02:07 <steev> did we move to the EDP thing with 5.15 or was that 5.16

02:07 <derzahl> i think i dropped that a long time ago because you or someone else here said its no longer needed

02:07 <steev> ah 5.16

02:08 <steev> steev@limitless:~$ uname -a

02:08 <steev> Linux limitless 5.15.12 #87 SMP Mon Jan 3 00:59:10 CST 2022 aarch64 GNU/Linux

02:09 <steev> that's using the distro_defconfig with a few extra tweaks of my own (changing to fq_codel, and building a few things in that i prefer in)

02:15 <derzahl> guess i do still have that line

02:15 <derzahl> efi=novamap pd_ignore_unused clk_ignore_unused

02:16 <derzahl> so just use pd_ignore_unused?

02:16 <derzahl> remove the rest?

02:16 <derzahl> you think that might be causing my problem?

02:17 <steev> no idea if it is or if you're missing something

02:19 <derzahl> well, one way to find out i guess:)

04:55 <steev> do make sure you're using the dtb as well - i can't recall if it's 5.14 to 5.15 or 5.15 to 5.16, there's a somewhat incompatible change, due to the backlight stuff being out of tree and now it's in - or maybe it's something that's still out and 5.17 will have it
