thx and that’s appreciated.

i am afraid your miatoll use other touch panel that nvt. you should be able to boot into pmos but without touch function. if you interested, plz feel free to hands on.

will do!,

i have an otg dock so i should be able to test plenty even without tactile

i build it and installed it using the following commands

git clone https://github.com/99degree/linux --depth=1 --branch next
cd linux

wget https://raw.githubusercontent.com/kalimokai/pmbootstrap/refs/heads/offical/helpers/envkernel.sh
source envkernel.sh

git fetch origin config
git branch config FETCH_HEAD
git checkout config -- arch/arm64/configs/sm71xx-xiaomi.config          
# i then edited sm71xx-xiaomi.config to disable the tux logo (to be able to differenciate from the stock miatoll pm kernel)

make defconfig sm71xx-xiaomi.config 
make -j$(nproc) 

pmbootstrap build --envkernel linux-postmarketos-qcom-sm7125
pmbootstrap flasher flash_kernel
fastboot reboot
#penguins are not visible => pmbootstrap did use the right kernel

here what i got:

• adb is not working
• usb keyboard not working
• no usb power
• sddm lag (no gpu perhaps ?)
• sleep doesn't turn off the panel
• no tactile

except for the fact i removed the tux logos this feels like exactly the same kernel.

did i make a mistake ? was 99degree/linux:next identical to pmos' kernel ?
what branch should i use ?

i switched to you branch of pmaports and added the packages you added in your ci.

But now i get an error saying that super failed to mount.

i tried reflashing the stock super to no avail.

yes, the build under my account does not proof for ufs pmos. my suggedtion is stick with a working pmos branch of your own.

i never compile the kernel this way so sorry i cant tell. please use official pmos kernel build procedure. if in doubt, please refer github action file.

and you can use official pmbootstrap then merge the firmware miatoll apk source code of pmaport. in additional with adbd-linux. so better start with official build（by pmbootstrap init, in your machine） and add addition apk package such firmware-xiaomi-miatoll and adbd-linux apk. thus you can have advantage of both side.

or you can install firmware files into your own rootfs/lib/firmware. note that ufs build might have a special root disk img structure and not easily modify this way rather than sdcard build.

my build purposely disable the ufs hw in device tree, and lack support of dynamic partition apk. if you wanna enable this you need to compile your own kernel and add support for dynamic partition apk as well as setting i dont know.

if you wanna have adbd, you have to dig with

if you have any plan for discuss plz create new issue ticket

happy hacking
