On these Barebones PSR 2 is recognized as supported but is very buggy:
- Upper third of screen does sometimes not updated, resulting in
disappearing cursors or ghosts of already closed Windows saying behind.
- Approximately 40 px from the bottom edge a 3 pixel wide strip of randomly
colored pixels is flickering.
PSR 1 is working fine however.
This patchset introduces a new quirk to disable PSR 2 specifically on known
buggy devices and applies it to the Tongfang PHxTxX1 and PHxTQx1 barebones.

Parralel to this there is a patch fixing the root cause of this issue:
https://gitlab.freedesktop.org/drm/intel/-/issues/7347#note_1785094
So this quirk might only be relevant for stable kernels, depending on when that
other patch gets merged.
