support for SM6150

[nookgit12]

plz i dont know how to write these config files so i want to ask yall to make config for SM6150 (snapdragon 675)

[sndnvaps]

@nookgit12 i have init the project for xiaomi note 7 pro(violet), platform is sm6150
now it can build boot-violet.img, but need more time to dump the dsdt.aml from my cell phone

[sndnvaps]

when i try to port edk2 to sm6150 platform, i had got some trouble
like this

is any one can give me some advices....

[Sasmithere]

can you send the boot-violet.img ? i used dipper img(personal modified version) to split emmc partitions to win esp etc ...
so far i am not able to make a boot img for it

[sndnvaps]

@Sasmithere in xiaomi_violet-edk2-boot-violet.zip contains 2 file, edk2-boot-violet.img and edk2-boot-violet-old.img

xiaomi_violet-edk2-boot-violet.zip

[Sasmithere]

i'll try both and return with an update

[Sasmithere]

@sndnvaps the old img one seems to boot into efi shell but my otg usb keyboard doesn't seem to work , i was wondering if you still have the .dsc , .fdf and .conf related files for it , i want to change the cmdline so it automatically boots to windows partition

[sndnvaps]

@Sasmithere I have push the change to github
sndnvaps@45b4445
sndnvaps@e44c5ab
the efi binary and my port for button.dxe etc.
sndnvaps/edk2-msm-binary@c54e69c

i hope it can help you.

Hey @sndnvaps @Sasmithere

I came across this project and thought it might be useful for your work:

GitHub: https://github.com/Project-Aloha/mu_aloha_platforms
Porting Guide: https://aloha.firmware.icu/PortingGuides/SimpleGuide.html

[sndnvaps]

@Thirumal-Palwai i had also read the https://aloha.firmware.icu/PortingGuides/SimpleGuide.html , i made the change base on it ...
what i port the dxe file use Ghidra
but it seem had some bug on platform sm6150 ,made it cann't run . only work is UEFI Shell, pwm,vol_up,vol_down still not work...
may be need uart debug to get the really problem....
i had one idea, use uart shell to get the problem of ui not work, but i dont known how to get the uart work

@sndnvaps thanks for the files , i think the tech stack which calls
The graphicsconsoledxe.efi which also combines buttonsdxe is causing the ruckus I'll be approaching this issue in these ways :

1. fix the graphicsconsoledxe.efi by dumping and recompiling then insert some dummy registers which are causing the issue and i did saw some registers having unknown as address (hard)
2. use a dummy graphicsconsoledxe.efi which returns efi_success as true and goes to text based interface (medium)
3. change the stack in which graphicsconsoledxe is called and remove it from there , inshort remove it from the call stack(hard)
4. build graphicsconsoledxe from scratch myself from the xbl.elf file or search internet for something similar (very hard 💀)
5. and last is i will try to change the bootdef.c and boot.c so it automatically boots into uefi boot menu

@sndnvaps

is emmc storage not supported ?

[Sasmithere]

close 🤏🏻 but no touchscreen and pwm , vol_up and down work , just scripted to auto boot to simple-init

[Sasmithere]

i think i fixed it ? i dont know
can you see this video log?
