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
VIA Unichrome->drivers/gpu/drm/via
v1->v2:
1.Add drm via driver to the patchset.
2.Remove related drm_pciids.
3.Remove related drm uapi header files.
4.split to series avoid large patch email.

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked mga driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Matrox-->driver/gpu/drm/mga
It's time to remove this driver.

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked tdfx driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
3dfx Glide-->driver/gpu/drm/tdfx
It's time to remove this driver.

2.25.1
Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked sis driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Silicon Integrated Systems->drivers/gpu/drm/sis
It's time to remove this driver.

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked r128 driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
ATI Rage 128->drivers/gpu/drm/r128
It's time to remove this driver.

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked i810 driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Intel i810-->driver/gpu/drm/i810
It's time to remove this driver.

2.25.1
Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked these drivers obsolete 7 years ago.
And the mesa UMD of this drm driver 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
VIA Unichrome->drivers/gpu/drm/via
It's time to remove these drivers.

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked these drivers obsolete 7 years ago.
And the mesa UMD of this drm driver 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 drivers.

Are we really sure that all users of these are gone? Also, I'm not really
seeing the benefit of this, we've managed to split out the legacy code
quite well, so carrying around isn't hurting anything afaics?

My first reaction was 'no way'. But then I thought about possible users
of this code and I cannot see anyone relying on it. You'd need an
ancient userspace Mesa library plus the most recent kernel. And all the
rendering is OpenGL 1.x. Are there even Linux programs for that?
So as far as I'm concerned
Acked-by: Thomas Zimmermann <[email protected]>
DRM's legacy infrastructure could be kept for a few more releases. Just
in case one of the drivers makes a comeback.
There is code in nouveau that uses legacy functionality for its ancient
userspace. I think we should scrap that as well. (See
NOUVEAU_LEGACY_CTX_SUPPORT.)
