how to checkout specific kernel from android git branch?

Hi all,
I'm having trouble trying to check out a version of the android source code from the git repository, with a known build.
For example, my Droid 1 is running:
2.6.32.9-g68eeef5
[email protected] #1
frg83d
I first figured that g68eeef5 referred to the git hash, but using gitk it appears that this is not a valid hash.
Does anyone know how I might be able to grab the kernel code for this build?
Thanks!
George

You could check out this guide http://stackoverflow.com/questions/315911/git-for-beginners-the-definitive-practical-guide#316055, in case you haven't already. It's got info on checking out branches - you'll need to know its name - and a lot more.
It seems g68eeef5 is kernel-specific - it might correspond to a revision/version of the kernel only (as opposed to the android system). That would not correspond to a branch though - kernel or android - rather to a revision inside a branch I'd think.

right, i'm trying to find the exact kernel branch or revision. g68eeef5 can't be a hash, since it has a 'g' in it, so i'm not sure what it corresponds to exactly.

[Q] Looking for Stock Android 3.2 Xoom Kernel Source

Hi guys,
I'm a kernel developer having trouble flashing a new kernel using fastboot on my rooted stock Xoom running Android 3.2. I flash my new kernel, and it gets stuck booting at the Motorola dual-core screen, and I have to reset and reflash the rootboot.img I got from these forums. I need to build some kernel modules, but I can't find the 2.6.36.3-gb899528 kernel on git anywhere. Before linking me to tegra or honeycomb git, please make sure this is the correct version, as I've tried most of the current branches. If I can't flash a new kernel, I can at least build and load the kernel modules I need.
Thanks in advance for any help.

http://android.git.kernel.org/?p=kernel/tegra.git;a=summary
Use the android-tegra-2.6.36 branch

Thanks, I tried that branch, but the vermagic string on the kernel modules is wrong (in the case of the most recent revision in that branch the vermagic string is '2.6.36.3-g9001adc SMP preempt mod_unload ARMv7' but I need it to be '2.6.36.3-gb899528 SMP preempt mod_unload ARMv7' to load the module on the Xoom). Android doesn't seem to let you force load kernel modules, so this remains an issue. Is it just another revision in that branch maybe? I'll try a few of the other revisions, but any other help would be appreciated.

Interesting -- I can't find it either. The b899528/9001adc refers to a git commit-ish (disclaimer: not a git expert), eg., http://android.git.kernel.org/?p=kernel/tegra.git;a=commit;h=9001adc
But http://android.git.kernel.org/?p=kernel/tegra.git;a=commit;h=b899528 doesn't resolve . . . they could be still working to get the GPL components made available?

Very strange indeed. Well it looks like that is out then. Is there a trick to building a kernel for the Xoom? Is there a certain base offset to use? I've built and flashed kernels for many other Android devices, but for the life of me cannot get one working with the Xoom.

Unable to load wifi module for ASUS ROG Phone 1

Specifications:
Phone: ASUS ROG 1
Model Number: ASUS_Z01QD
Android version : 8.1.0
Firmware: WW-15.1630.1907.98
Kernel Version: 4.9.65-perf
I have an ASUS ROG 1 Phone. It came with Android 8.1 and firware version WW-15.1630.1907.98. I took the kernel source code from ASUS site. Source code version: <new user on XDA hence unable to post the src code link.>
Was able to build successfully and flash to the phone. Rooted the phone following to that. The problem is that the wifi wasnt working after flashing the new kernel .
1. I checked the modules loaded lsod, from adb and it didnt show the wil6210.ko loaded.
2. I tried insmod /modprobe wil6210.ko and was constantly getting the following errors:
a. disagrees about version of symbol module_layout android kernel
b. required key not available .
c. No such file or directory.
3. I tried building the kernel with the SIG flags disabled in the .config file and flashed to the phone. Yet ended up getting errors like no such file or directory and required key not available.
Any help will be really appreciated.
@nathanchance

You need to rebuild the Wi-Fi module against the source that you compiled then flash it. Alternatively, you can try building the Wi-Fi source into the kernel image but that is usually broken or you can force the module to load by whitelisting it in kernel/module.c (there are commits floating around that allow this) but it can open up a security vulnerability.

Thanks for your reply.
The source code I downloaded from the ASUS website, the wifi module code was a part of it. So whille building the kernel the module <wil6210.ko> also got built along with it.
So the wifi module did get built against the same source.

How to extend screen on a secondary monitor in android-x86

I'm looking for a a way to get two separate display outputs, use eDP to connect 1st monitor(PC monitor), use HDMI to connect 2nd monitor(touch screen monitor).
From https://www.android-x86.org/, there's below descriptions, seems still not supported.
To-Do List​
Multiple displays support
Better power management
Miracast
From https://blissos.org/, download below android generic iso image, and after flashed this iso image, we can found which support dual monitors,
display the same content on both monitors.

For above "Android-Generic 11 AOSP" iso image, checked the boot log, there's "HWC=drm_minigbm GARLLOC=minigbm_intel" in the kernel command line,
but for bliss os iso image(download or build locally), there's no "HWC=drm_minigbm GARLLOC=minigbm_intel" in the command line,
only support below options on bliss os, but all are not work for dual monitors, normally on 1st monitor, there's console on 2nd monitor,

we tried to use https://github.com/intel/minigbm/tree/android10-release to replace external/minigbm, met some build error, from this github, latest minigbm_intel is android 10, minigbm on bliss os 14 is android 11,
and above "Android-Generic 11 AOSP" iso image is actually android 12.
Seems not related with kernel, since we checked 89 kernel patches of android r under vendor_ag, all kernel patches have been merged into blissos 14.
When we tried the "HWC=drm_minigbm GRALLOC=intel", only have console on dual monitors, there's crash for surfaceflinger, sdcard has not been mounted so far, error please refer to attached error.
Why dual monitors supported on "Android-Generic 11 AOSP" iso image?

@electrikjesus could you have a look at this issue? thanks a lot

It will require a number of updates to drm_hwcomposer, gbm_gralloc, libdrm, etc. in order to get second screen activities working properly on AG 11 base. It is working on AG 12, so far, and most of those updates are compatible with AG 11 code base.

@electrikjesus Appreciate your quick reply!!
From https://www.android-x86.org/, latest open code base branch is r-86(Android 11), when AG 12 base(Android 12) could be ready and open? Is there any time plan?
From my understanding, updates mentioned below are not included in r-86(Android 11) branch yet, right?
Where can we get these updates so far? we really need these prefect patches,
could these patches can be found by below https://github.com/BlissRoms-x86/manifest/tree/s-x86-r1.1 ?
Just now, I compared r-86 branch and s-x86-r1.1 branch, there are very big change for drm_hwcomposer and libdrm, and grm_gralloc is not existed in s-x86-r1.1 branch.
It will require a number of updates to drm_hwcomposer, gbm_gralloc, libdrm, etc. in order to get second screen activities working properly on AG 11 base. It is working on AG 12, so far, and most of those updates are compatible with AG 11 code base.

Things for that have been made upstream. So gbm_gralloc is now working from mainline repo/Linux.
The recent experiments coming from @HMTheBoy154 also have these included, so you can check his repos for details

Thanks again!! It's very helpful.

Hi all,
I'm also trying to get dual monitor to work, with extended Android screen.
It is working on AG 12, so far

I tried "Bliss-v15.0-Alpha-android_x86_64-OFFICIAL-foss-202112151838-nb-sd-ksu-gearlock-ex_vt-console_all-mesa-drivers-crocus.iso" and
"android_x86_64-a12.1_r1-03.16.22-01-mesa22-ksu-gapps-libndk-sd.iso", however, I get the same result as the OP - the second display only shows a terminal.
Do I need to use later code and build from source? Or are there any kernel options that needs to be enabled?
Notes:
- Using a AMD Radeon RX 580
- Getting overlay glitches, but the workaround "boot using minigbm_intel" does not work for me (Android doesn't boot then)
Best regards,
Markus

[HELP] My tablet goodix touchscreen is inverted

I have onkyo ta2c-74z8 tablet.
There are no driver so I need to use other tablet goodix driver and edit "touchsettings.gt".
I was extracted cfg(0/1/2) values from linux kernel source code.
But it doesn't works correct. x and y axis was swapped and x axis was inverted.
I edit "x2y=0" to "x2y=1". It works. But "x2x" is not working.
How to fix this?

It's driver source code from linux kernel.
