13:26 <hexdump0815> does anyone here maybe have a working v5.15 kernel config for lazor? i only get to https://pastebin.com/raw/xYruqnja based on cadmium kernel configs

13:26 <hexdump0815> are there still any patches required to run mainline on lazor/trogdor/sc7180?

15:29 <robclark> hexdump0815: I've been running upstream kernel on lazor for about a year now, there shouldn't be anything missing.. but I suppose there could have been a regression? I've not had a chance to try v5.15 final, but have been using v5.15-rc3 with no issue

18:04 <hexdump0815> robclark: i just built and tried an 5.15.0-rc3 kernel, but it still does not work and this time i do not even get any output on the suzyqable serial console - so maybe there is something wrong with my kernel config - it would be good if you could upload your working config somewhere or point me to it if its online already

18:06 <hexdump0815> i'm trying it on the 4gb wifi only model - iirc you were recently also testing on this one - right?

18:20 <robclark> hexdump0815: I take the original kconfig, and then `make olddefconfig`.. (well actually I make a few other tweaks like enabling btrfs since that is what the fedora rootfs image is using

18:20 <robclark> fwiw, https://gitlab.freedesktop.org/jbarnes/cros-util is what I use for kernel build

18:21 <robclark> I guess I am still using `fw_devlink=off` in kernel cmdline.. not sure if that is still needed or if the fw devlink issues are sorted by now

18:33 <hexdump0815> i have fw_devlink=off in my cmdline too to avoid trouble until this topic is over :)

18:39 <hexdump0815> thanks for the cros-utils link - this look like a good plan ... i'll give this approach a try

18:39 <robclark> np

19:55 <hexdump0815> starting from the cros config looks much better - display is still black, but system is booting - this is something from where i can debug forward what the problem is :)

20:02 <robclark> hexdump0815: oh, I guess I should have pointed out that cros config doesn't have VT and fbcon.. so there are a few extra things to enable if you want a console

20:08 <hexdump0815> robclark: ah right - i hope to get all that sorted out - anything else you remember to keep in mind?

20:12 <robclark> I think I had to enable a few things that fedora wanted (but other distro's might not), like CONFIG_TMPFS_POSIX_ACL and CONFIG_TMPFS_XATTR?
