13:26 <jenneron[m]> janrinze: hi, they added dojo dts, please test it and upload dmesg https://gitlab.collabora.com/google/chromeos-kernel/-/commits/for-kernelci/?ref_type=heads

14:53 <janrinze> jenneron[m]: Hi. I have my build environment scripted now. what is the urls for the checkout of this kernel?

14:54 <janrinze> jenneron[m]: oh. just get the branch for-kernelci

14:58 <janrinze> jenneron[m]: git clone --depth=1 -b for-kernelci https://gitlab.collabora.com/google/chromeos-kernel.git linux Should be okay, right?

14:59 <jenneron[m]> yep, that should be okay

14:59 <jenneron[m]> i would use something like git clone --depth=1 -b for-kernelci https://gitlab.collabora.com/google/chromeos-kernel.git linux-20240228

15:00 <jenneron[m]> so you have date in directory name in case you want to clone this kernel again in the future

15:27 <janrinze> jenneron[m]: https://github.com/janrinze/gnu-linux-on-hp-chromebook-x360-13/blob/main/debugging/dmesg_dojo.txt

15:28 <janrinze> jenneron[m]: it is possible that my current kernelconfig is not properly matching this kernel.

15:32 <jenneron[m]> janrinze: can you also upload kernel config of this kmsg?

15:34 <jenneron[m]> janrinze: do you have CONFIG_SND_SOC_MAX98390 enabled?

15:39 <janrinze> jenneron[m]: yes I have. found this: https://patchwork.kernel.org/project/linux-mediatek/patch/20240227120939.290143-9-angelogioacchino.delregno@collabora.com/

15:55 <janrinze> jenneron[m]: platform mt8195-sound: deferred probe pending: mt8195_mt6359: ETDM2_OUT_BE: codec dai not found This seems to be consistent if I change everything to a module.

16:01 <janrinze> jenneron[m]: in the kernel configs the only DAI reference I can find are the Qualcom ones. CONFIG_SND_SOC_QDSP6_*_DAI which depends on QCOM_APR and SND_SOC_QCOM which in turn depends on ARCH_QCOM.

16:15 <janrinze> jenneron[m]: after a bit of digging, the ETDM2_OUT_BE label is not the device defined in the dojo dts. I think we have a slight misalignment between mt8195-cherry.dtsi and mt8195-cherry-dojo-r1.dts

16:17 <janrinze> on the bright side: touch screen is working now!

16:19 <janrinze> And as a bonus the nvme speed is much better now. 1115.28 MB/sec

17:16 <jenneron[m]> janrinze: ok, can you upload config?

18:12 <janrinze> jenneron[m]: after resizing the kernel partition I can have max 64MB kernels now. I'll put the latest dmesg and kernel config here.

18:15 <janrinze> jenneron[m]: https://github.com/janrinze/gnu-linux-on-hp-chromebook-x360-13/blob/main/debugging/config_6.8.0-rc6-next-20240228.txt And https://github.com/janrinze/gnu-linux-on-hp-chromebook-x360-13/blob/main/debugging/dmesg_dojo_6.8.0-rc6-next-20240228.txt

20:35 <jenneron[m]> janrinze: btw is your snow chromebook rev4 or rev5?

20:44 <janrinze> jenneron[m]: no idea, how to find out?

20:44 <jenneron[m]> cat /proc/device-tree/compatible

20:47 <janrinze> jenneron[m]: I haven't powered it on for quite some time. Need to find the right SD card. I'll have a look.

20:47 <jenneron[m]> janrinze: you can just flash a pmOS image to any sd card, we have prebuilt images for snow

20:48 <jenneron[m]> https://images.postmarketos.org/bpo/edge/google-snow/gnome/

20:48 <jenneron[m]> or https://images.postmarketos.org/bpo/edge/google-snow/sway/

20:49 <janrinze> jenneron[m]: that's nice. I don't have a large set of empty SDcards. most have some existing OS or backup of an old OS.. i'll see if i can backup a few cards and have something available.

20:57 <janrinze> jenneron[m]: found the charger, it is a rev. 4 (march 2013 model)

20:57 <jenneron[m]> i see

20:57 <janrinze> runs Debian 8 :-D

20:57 <jenneron[m]> is there any chance you can give me an ssh connection to a snow running pmOS?

20:58 <janrinze> jenneron[m]: LOL!

20:58 <jenneron[m]> we need to adjust ucm configs for rev4

20:58 <jenneron[m]> both of my snow boards are rev5

21:00 <janrinze> I'll have to buy some spare SDcards and USB disks. That will allow me to do some more tinkering.

21:01 <jenneron[m]> pmOS on snow doesn't boot from USB currently

21:01 <jenneron[m]> only SD and eMMC

21:01 <janrinze> yeah, and the SDcards stick out on the side. (USB would stick out on the back though..)

21:02 <jenneron[m]> bootloader doesn't recognize most of USB sticks anyway

21:02 <jenneron[m]> i think it wants only USB 2.0 sticks

21:02 <jenneron[m]> no matter which port you're connecting to

21:03 <janrinze> the back has one USB3 and one USB2 connector

21:03 <jenneron[m]> yeah it doesn't matter

21:03 <janrinze> I remember using the USB3 as a fast network to another system.

21:03 <jenneron[m]> bootloader doesn't recognize USB 3.0 sticks connected to either port

21:07 <janrinze> got experience with tftpboot? :D

21:36 <weirdtreething[m]> <jenneron[m]> "bootloader doesn't recognize..." <- are you able to run your own u-boot on it?

21:40 <jenneron[m]> weirdtreething[m]: only as secondary bootloader

21:40 <jenneron[m]> i couldn't get it to work as primary

21:41 <jenneron[m]> https://wiki.postmarketos.org/wiki/Samsung_Chromebook_(google-snow)

21:52 <weirdtreething[m]> <jenneron[m]> "i couldn't get it to work as..." <- ah got it

21:53 <jenneron[m]> i thinkGrimler works on it for exynos 5420
