im Casey, 🏳️🌈 queer hacker in Berlin! # LinuxMobile and @ postmarketOS is my jam I maintain U-Boot for Qualcomm devices and do other cool embedded stuff @ Linaro # GoVegan 🌱 personal account: @ casey
i've been pretty quiet regarding work stuff lately, but finally have something to share!
here we have Qualcomm display drivers up and running, demo'd on the Ayaneo Pocket S2, but it also works on the SM8650 HDK.
This isn't relying on an existing framebuffer being set up, this is U-Boot as the first stage bootloader. So there unfortunately isn't much of a benefit here on most of the phones we run U-Boot on today since we already have a framebuffer xD
The pocket S2 was a "fun" first target since it uses dual DSI, so both DSI controllers are used to drive a single panel.
It's gonna take quite a lot of cleanup before this can go upstream (particularly in the clock drivers), but I hope we can expand this support to other platforms and enable additional functionality like DSC. This brings us one (big!) step closer to a viable alternative bootloader for Qualcomm mobile devices.
That all bring said, the current diff is ~10k LoC 😅
