21:34 <sicelo> i've built a kernel for Librem5, and took the latest image from Pinephone iirc (or was it generic arm64?). anyway, i'm getting "Failed to execute /init (error -13) ... Starting init: /sbin/init exists but couldn't execute it (error -13)" error when booting

21:34 <sicelo> i think kernel is ok. what should i set for `init=`?

21:37 <sicelo> my uboot cmdline is 'setenv bootargs rootwait root=/dev/sda2 rw console=ttymxc0,115200 debug console=tty0'

21:38 <sicelo> yes, it's sda2 ... because i'm using sd card, and on the Librem5 it's sitting behind USB. u-boot knows how to find it there, and i've built both ext4 and the usb support in, so that's not the problem

21:38 <Wizzup> sicelo: does it mount rootfs?

21:39 <sicelo> yes

21:39 <sicelo> let me see if i can upload a picture (because no serial to this thing) :p

21:39 <sicelo> serial is ... something like N900

21:45 <sicelo> https://www.imgpaste.net/image/STA7sb

22:00 <Wizzup> interesting

22:00 <Wizzup> maybe armhf kernel and userland is arm64 or vice versa?

22:00 <Wizzup> maybe google for the error a bi

22:01 <Wizzup> wait..

22:01 <Wizzup> /etc/init ?

22:01 <Wizzup> Does it manage to run /sbin/init ?

22:01 <sicelo> https://docs.kernel.org/admin-guide/init.html

22:02 <sicelo> it says it can see /sbin/init, but can't run it

22:02 <sicelo> Starting init: /sbin/init exists but couldn't execute it (error -13)

22:02 <Wizzup> I don't see that on the screen

22:03 <Wizzup> and you're sure that sda2 contains /sbin/init?

22:03 <Wizzup> maybe run 'file' on it ot see what kind of file it is

22:03 <sicelo> it's there on the screen - at 7.125814

22:04 <sicelo> and yes sda2 contains the file. sbin/init: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=a32a90ca33581febfd8a89839d20aeec0b85b975, for GNU/Linux 3.7.0, stripped

22:06 <sicelo> let me try set init=/bin/sh and see what happens

22:09 <Wizzup> sicelo: no

22:09 <Wizzup> sicelo: that says /etc/init

22:11 <sicelo> ah indeed.

22:12 <sicelo> /sbin/init is tried a bit earlier up. so somehow it fails. actually init=/bin/sh also doesn't work

22:12 <Wizzup> the tomoyo stuff seems suspect

22:14 <sicelo> that one's there in mobian too. i'm not sure where it comes from, but i don't think it's the issue

22:14 <sicelo> maybe let me re-do the rootfs in case something's borked somewhere

22:16 <Wizzup> you could perhaps chroot from another arm64 device just in case

22:16 <Wizzup> ok

22:17 <Wizzup> does it work wiht the mobian kernel?

22:17 <Wizzup> maybe try that first

22:18 <sicelo> it is the mobian kernel ... just not the actual binary, because theirs (including pmOS) expects an initramfs, so they haven't built in stuff like SD card support, etc.

22:21 <Wizzup> ok

22:21 <Wizzup> there might some trickyness there, like certain things having to be built in

23:37 <sicelo> yay! progress ... now x server is crashing. but at least that means we got somewhere

23:40 <Wizzup> cool :)

23:44 <sicelo> https://paste.debian.net/1311092/

23:44 <sicelo> i think i must sleep now and see this next time :-)

23:47 <Wizzup> seems like you might need some xorg conf

23:47 <Wizzup> either that or our mesa lacks the driver

23:47 <Wizzup> but I don't think it does

23:54 <sicelo> we might be missing it. i was just doing a find, and this is what i can find:

23:54 <sicelo> sudo find . -name "*etnaviv*"

23:54 <sicelo> [sudo] password for mobian:

23:54 <sicelo> ./usr/lib/aarch64-linux-gnu/dri/etnaviv_dri.so

23:54 <sicelo> ./usr/src/linux-headers-5.10.0-28-common/include/uapi/drm/etnaviv_drm.h

23:54 <sicelo> ./usr/src/linux-headers-6.1.15/include/uapi/drm/etnaviv_drm.h

23:54 <sicelo> altough i think i saw it in the sources. maybe we don't have config option to actually build it

23:54 <sicelo> i.e. mesa

23:58 <sicelo> ah, the first one is from mesa, so we have it
