Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked these drivers obsolete 7 years ago.
And the mesa UMD of these drm drivers already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
3dfx Glide-->driver/gpu/drm/tdfx
Matrox-->driver/gpu/drm/mga
Intel i810-->driver/gpu/drm/i810
S3 Savage-->drivers/gpu/drm/savage/
ATI Rage 128->drivers/gpu/drm/r128/
Silicon Integrated Systems->drivers/gpu/drm/sis/
It's time to remove these.
At first, I was about to reply a simple 'No'. But thinking about it, we should consider doing this. Every other component (Mesa, X11, 3d games) that could realistically use these drivers is obsolete by now.
And please add via to the patchset. There's on-going work to create a KMS driver and that's easier without the old UMS driver.
Best regards Thomas
