How to enter flash mode
Installation
Use pmbootstrap to build your own installation image of another x86_64 device, as we have to use a prebuilt kernel on this one.
$ pmbootstrap init
$ pmbootstrap install --sdcard=/dev/sdX
(we use sdcard as internal storage is slow, buggy and dm-verity is acting strangely)
Notes
This x86 tablet has a Mali GPU, which is quite a weird combination. The Lima driver has not yet been tested on x86.
It uses the Simple Firmware Interface for discovering system timers and non-enumerable buses, but other stuff can be found using PCI. SFI has been dropped from mainline, so unless that is merged back the best thing is close-to-mainline on a fork of kernel version 5.10 which was the last kernel that supported it or use second stage bootloader Petitboot to boot newer kernels with devicetree.(See Motorola RAZR i (XT890) (motorola-smi)'s device package).
Considering that regular UEFI is supported in Linux, porting EDK-II might be an interesting option for getting mainline Linux to boot .
Downstream kernel
For working 3D graphics, mainline would be required, but having a port with downstream could be used in the meantime.
