Development [INFO] PostmarketOS Linux boot on Xiaomi Pad 5 (nabu)

[serdeliuk]

I had no idea there were so many hurdles, Im no a dev ofc. Licenses and all that other stuff u mentioned I didn't know.

All of those steps are required because i want to release the PostmarketOS for nabu officially supported, under the PMOS repositories on GitLab, and not as is on a noname/unknown repo on my GitHub account.

I think porting PMOS is just an appetizer for nabu, the real highlight is the EDK2 port and the porting of other Linux distributions. I think, based on your work, we can quickly achieve PCizing this device and extending it to all aspects except MacOS.
I think github is much more friendly and easy to use than gitlab, which is used for PMOS, so I strongly hope that your work outside of pure PMOS (Linux Kernel, EDK2) can be put on github. Even though I'm still a kernel rookie, I look forward to making pull requests and contributing

Interesting that you mentioned MacOS as the whole thing on my side started prior M1 release when i built a few hackintoshes around different CPUs and a few apps/helpers as macAura or VirtualBiosMod in my head was to port OSX for ARM on my lavender and knowing that they started to add universal binaries to their beta OSX i was super exited thinking that the new mac will have as well UEFI. At this point we know that they do not use UEFI anymore, yet EDK2 port for devices still remains an interesting thing, i will port Clover Bootloader at some point which is EDK2 mainly.
GitHub and GitLab are almost the same, both offer free and/or paid services, so is a matter of users what they choose, some prefer GitLab as is not owned by Microsoft....

Yeah, the real work happens before you upload it to hosted git...
And after that upload you have to cater with all the bikeshedding^Wreviewing... ;-)

What the heck is EDK2? !i googled it but unfortunately your brain was made with more of them braincells and IQs than my amoeba-brain has.

The Tianocore's EDK2 is an OpenSource framework for firmware builders, any computer has a firmware and if is recent enough it is possible to be a UEFI firmware and maybe built on EDK2 platform/framework. In regards to nabu and qualcomm the XBL.img is an UEFI bootloader that contains UEFI drivers, this means that our device has an UEFI firmware that may load a custom UEFI bootloader, in my case a bootloader made on UEFI EDK2 platform. Even XBL bootloader is built on EDK2 framework. At this point a custom EDK2 bootloader can load original XBL devices drivers, some of them patched to fix different things that were not used at boot stage by the hardware vendor (Xiaomi in our case) and then instead to boot Android can boot any UEFI OS, mostly Windows, but can boot anything, including Linux. CloverBootloader is as well built on EDK2 platform.

With your kernel, is it possible to compile Twrp with the functional screen? I have tried several recoveries and sometimes they start and sometimes they don't. I don't know why. Only 1 cm is visible from the top. The first image is twrp, the second Orange fox and latest is bootloader

 

[LesGaR]

Do you want to port clover or opencore bootloader? I have installed several hackintosh and in the end, change to move to opencore, although it is more complicated to readjust, it seems more stable.
1 day ago they have updated the DSDT of the ED2K-MSM project. Based on the change log they resolved

Nabu: DSDT Update
- Fixed battery manager bug
- Added a test fuel gauge device
- Synchronize ACPI with the main line

Can these changes be useful for your postmarketOS port?

Con su kernel ¿es posible compilar Twrp con la pantalla funcional? He intentado varias recuperaciones y a veces comienzan y a veces no. No sé por qué. Solo se ve 1 cm de la parte superior. La primera imagen es twrp, la segunda Orange fox y latest es bootloader

¿Quieres portar clover o opencore bootloader? He instalado varios hackintosh y al final, cambio de pasar a opencore, aunque es más complicado de reajustar, parece más estable. Hace 1 día han actualizado el DSDT del proyecto ED2K-MSM. Según el registro de cambios que han resuelto

Nabu: Actualización DSDT
- Corregido error de administrador de batería
- Se agregó un dispositivo de indicador de combustible de prueba
- Sincronizar ACPI con la línea principal

¿Pueden estos cambios ser útiles para su puerto postmarketOS?

Please use Google Translate to ask your questions if you expect answers. I port Clover because is better than OpenCore, on one hand, on the other one I prefer Clover.

I wanted to say that if the problem of the screen is because of the kernel or twrp. I've tried compiling Twrp but I can't get the screen to work.
The question is you think that with your mainline kernel you will be able to compile functional Twrp.
There's no rush for me to release it, it's to you know if you recomend me to keep testing builds, or recomend me to wait for you to release the mainline kernel.

Hi, the Renegade community has fixed the charging capability of nabu on the WOA project, is it possible that the driver built on Windows On Arm could be a reference for PMOS?

Unfortunately Windows drivers do not work on Linux. Also are closed source, so there is no reference.
