RCA Voyager III (sofiaboard)
This device has been tested with postmarketOS, but its device package has not yet been added to the postmarketOS repositories. This means that it cannot be selected in pmbootstrap. Status: Uses prebuilt kernel, therefore cannot be packaged |

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.
