[oplus-5.10] Missing & Broken Kernel Code in Oneplus Ace/Race ColorOS 12.1 Source

[techyminati]

Hi the following kernel drivers are missing in kernel code

• vendor/oplus/kernel/touchpanel/oplus_touchscreen_v2/ does not exist https://github.com/OnePlusOSS/android_vendor_mediatek_kernel_modules_mt6895/tree/oneplus/mt6895_s_12.1_oneplus_ace_race/vendor/oplus/kernel & these are symlinked here https://github.com/OnePlusOSS/android_kernel_5.10_oneplus_mt6895/blob/oneplus/mt6895_s_12.1_oneplus_ace_race/drivers/input/touchscreen/oplus_touchscreen_v2

• Also the uff_fp_drivers are missing vendor/oplus/secure/biometrics/fingerprints/bsp/uff/driver does not exist

• Also the whole kernel is broken , it does not compile at all, I'm using Clang 11 in my build, here are logs.

Hello Oneplus, this if a followup regarding your mail, in which you asked me to rebuild kernel

I've tried same and here are the logs

drivers/input/Kconfig:215: can't open file "drivers/input/uff_fp_drivers/Kconfig"
make[2]: *** [../scripts/kconfig/Makefile:88: mgk_64_k510_defconfig] Error 1

• Now the build does not even start since uff fp drivers are missing, which i already told here [oplus-5.10] Missing & Broken Kernel Code in Oneplus Ace/Race ColorOS 12.1 Source  #1 (comment)

• Now i tried to build further after dropping uff drivers (temporarily) & here are more errors

• Hi oneplus i just got your mail, you asked to use oplus6895.config, but that does not exist here

after a lot of fight .. finally it compiled.

found a few issues with touchscreen code.
if using CONFIG_OPLUS_MTK_DRM_GKI_NOTIFY then all the CONFIG_FB code should be coming after the first config else all the code will give compilation errors.

Hi brother, I have the same problem as you. How did you solve it, thank you very much

[SukeCloud]

I tried to find the relevant code to comment it out, but I found more and more errors. It was really frustrating

[13THWARRIOR]

@CloudMeiyu can you check your config ... the issue is because of config ... you need to include android gki config, android recommend configs, mtk and oplus configs .... then it will compile fine.

[SukeCloud]

Thank you very much for taking the time to reply the message. I used mgk_64_k510_defconfig and oplus6895.config..... Do you need to make any other Settings? The documentation doesn't say anything else...

make O=out ARCH=arm64 mgk_64_k510_defconfig oplus6895.config What else do we need ? It's too hard brother. wailing

[13THWARRIOR]

@CloudMeiyu
yes please use merge tool in script folder in kernel to merge all these config :

1. gki_defconfig
2. android-base.config
3. android-recommended.config
4. mgk_64_k510_defconfig
5. oplus6895.config

you can remove redundant configs and use the merged config to build with googles gki build system.

yes the documentation are scarce for gki.

Brother Could you tell me how to use merge tool in script folder in kernel to merge all these config ..?
I checked the data and found that it was using "./scripts/kconfig/merge_config.sh" merge all these config
I don't know if it's right.

command to compile kernel :

./scripts/kconfig/merge_config.sh -m arch/arm64/configs/gki_defconfig kernel/configs/android-base.config kernel/configs/android-recommended.config arch/arm64/configs/mgk_64_k510_defconfig kernel/configs/oplus6895.config

mv -f .config .merged.config
(Looking through the data, I don't know why he did it.)
make O=out -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- KCONFIG_ALLCONFIG=.merged.config alldefconfig

[13THWARRIOR]

@CloudMeiyu well from kernel 5.10 onwards google started using llvm/clang (please go through google documentation) so not more cross compiling using gcc and regarding the merge tool please find the help documentation using a notepad or using -h or --help. Yes the path and script is the same. The reason we are merging multiple config as to specify which is vendor config and which is common and which is gki and android specific. Brings more clarity which config is for what.
