hexdump0815 / linux-mainline-and-mali-generic-stable-kernel

my kind of generic armv7l 32bit linux mainline stable kernel build - used on bananapi m1, asus tinkerboard, tx1 allwinner h3 tv box, r39 allwinner h3 tv box, orbsmart s92 tv box (same as beelink r89, tronsmart orion r28, very similar to ubox tv box), raspberry pi 3b and 3b plus in 32bit mode

trogdor: Where is 5.15.22-stb-cbq? #7

Open Geofferey opened 2 years ago

Geofferey commented 2 years ago

@hexdump0815 Was trying to run the build today, mainly so I can compile and reproduce the kernel exactly as you did. I think I am doing things correctly...

The error below seems to be stopping me....

Is there any way you could upload the 5.15.22-stb-cbq source so sudo ./get-files.sh chromebook_trogdor aarch64 bullseye can fetch? I don't want to substitute because I want to be sure the kernel comes out the same as yours on first rounds before I start jacking around with stuff. Thanks again dude.

EDIT:

Probably better we discuss here. :) If I have any other questions I will post them as comment. I think I got this.

@hexdump0815 Okay I got everything to build and copied the files to /boot following the commands in your script. I seem to be missing something tho...

When I run uname -a

Linux debian-trogdor 5.15.2-stb-cbq #1 SMP PREEMPT Sat Nov 20 12:28:33 CET 2021 aarch64 GNU/Linux

I would expect to see my date.

I'm pretty sure I'm missing step to dd if=kernel.img of=/dev/mmcblk1p1 How do I produce the resulting kernel image that needs to be flashed to the first/second partition? Did I make it and not even know?

EDIT:

Derp, my fear kept me back for a moment. I just needed to grow a pair and dd if=vmlinux.kpart of=/dev/mmcblk1p1 🤦 the .kpart meaning kernel partition I suppose.

hexdump0815 commented 2 years ago

yes - that dd is required as the chromebook bootloader will only boot kernels in that special format from that partition ... there is actually a second kernel partition in the images for testing - i'll write down how to use this soon, as it makes testing much easier

in case your self built kernel is bad, you can always boot the one from an image on usb/sd via ctrl-u ... btw. besides the things in /boot it is also required to put /lib/modules/ in place

regarding the 5.15.22 kernel: looks like i forgot to upload it - i'll try to upload it over the weekend

best wishes - hexdump

@hexdump0815 I got 5.15.36 running but can't seem to go past that. Do you have any tips on getting newer ones to work like 5.17.X or 5.16.X? I feel like I may be just missing something little. I did figure out the USB trick so that has been worlds of help today. 👍

Here is a GIST of the script I made from your notes to help make my life easier. It's still a WIP but maybe I can add something to it to help make the newer kernels boot? Maybe it's missing a step... As it stands I just pulled your .config from /boot and the cmdline from your notes in cbq.

Thanks for keeping up with me 😃 I am trying hard here lol.

some updates:

thanks a lot for your support and best wishes - hexdump

  1. I'm not sure if you're asking if 5.15.36 works. If so, yes it works just as well as 5.15.22 or better. I have tested up to 5.18-rc4 now and haven't noticed any regressions.

  2. This could prove useful, I'll have to try the boot flags tomorrow and see.

  3. Yes CONFIG_DRM_PANEL_EDP=y got me a booting kernel. Thank you for pointing ☝️ this out to me. I would've stayed lost for a while otherwise.

  4. Suspend and resume is working perfectly now, no issues on 5.17.X and up. Seems we get full deep considering I only lost 1% over a 4r period. I don't sleep much 😂

  5. I actually did try everything in there. Seems to be only the internal mic is detected. When running pactl list sources that's all I see. This is weird because I thought Lazor used the exact same card. It worked on Lazor? I think this might be a kernel side dt issue or lack of firmware (if any exist).

cat /proc/asound/cards reports:

 0 [sc7180adau7002m]: SC7180 - sc7180-adau7002-max98357a
                  sc7180-adau7002-max98357a

Here is message from alsactl init:

 alsa-lib main.c:1014:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
 Found hardware: "SC7180" "" "" "" ""
 Hardware is initialized using a generic method

This is what I could find in dmesg:

 [    5.422974] max98357a audio-codec-0: GPIO lookup for consumer sdmode
 [    5.422989] max98357a audio-codec-0: using device tree for GPIO lookup

 [    5.677936] input: sc7180-adau7002-max98357a HDMI Jack as /devices/platform/sound/sound/card0/input6
  1. The gist still needs some more work, if you can think of anything let me know. I kinda want it to end up in repos for other people like me who just want to build and test kernels. My goal with it is to make it adaptable so we can adjust a couple params and have it build for several devices.

No problem, I think if I try hard enough I can get this working nearly %100 it's already %90 lol. Thank you for the support actually.

happy to hear that it works now - this config option is new since 5.16 i think and that gave problems for many systems and thus appeared at different places on irc or elsewhere, so i also just found it somewhere :)

@hexdump0815 I have tried to address all your points. Check it out 🔢
