[ Cross posted to freebsd-current@ and freebsd-x11@. Please respect=20 reply-to and send all replies to freebsd-x11@. Thanks! ] Hi! I propose that we remove the old drm2 driver (sys/dev/drm2) from=20 FreeBSD. I suggest the driver is marked as deprecated in 11.x and=20 removed from 12.0, as was done for other drivers recently. Some=20 background and rationale: The drm2 driver was the original port of a KMS driver to FreeBSD. It=20 was done by Konstantin Belousov to support Intel graphics cards, and=20 later extended by Jean-S=C3=A9bastien P=C3=A9dron as well as Konstantin t= o match=20 what's in Linux 3.8. This included unstable support from Haswell, but=20 nothing newer than that. For quite some time now we have had the graphics/drm-stable-kmod and=20 graphics/drm-next-kmods which provides support for modern AMD and Intel=20 graphics cards. These ports, together with the linuxkpi, or lkpi, has=20 made it significantly easier to port and update our graphics drivers.=20 Further, these new drivers cover the same drivers as the old drm2 driver. What does the community think? Is there anyone still using the drm2=20 driver on 12-CURRENT? If so, what is preventing you from switching to=20 the port? Thank you Regards --=20 Niclas Zeising FreeBSD x11/graphics team
