Re: HEADS UP: DRM/KMS graphics driver updates

I built a GENERIC kernel from this branch and could not find any visible difference between it and the GENERIC from HEAD. X still does not start, nothing seems to be recognised in the dmesg. Perhaps some glue relevant on my laptop is still missing. My userland is from 8.99.24 some three days old, but I don't think the problem is due to the above being 8.99.22 (because of the dmesg). I can provide the dmesg, various lspci outputs and Xorg logs as well, if they would be useful.

Wonderful. I have been waiting for this over two years now for my HP laptop (Envy 17, Skylake (530), GeForce 950M. I guess I will have to disable nouveau and at least try the Intel graphics.

Cloning the git repo right now.

Obviously I am willing to test any and every development in this area.

NetBSD's DRM/KMS graphics drivers are currently based on Linux 3.15,
plus some backports. Several of us (me, maya, mrg, leot) have been
working on updating the kernel graphics drivers (i915drmkms, radeon,
nouveau, and now amdgpu). We did Linux 4.4 as an intermediate step
toward newer graphics, probably 4.18. My state is in the git branch
riastradh-drm at <https://github.com/riastradh/netbsd-src.git>.

Right now, it works in cursory testing on i945, Ivy Bridge, Haswell,
and Skylake, and some radeon devices. Unfortunately, with nouveau it
just blanks the screen and I haven't been able to figure out why.

Nevertheless, I'm planning to commit this to CVS soon so we can get to
work on 4.18 rather than get bogged down debugging 4.4 (and maybe
we'll figure out what's wrong with our 4.4 nouveau anyway -- probably
a really stupid bug like most of them have been), but still have 4.4
available for some newer hardware support than 3.15 in case netbsd-9
is ready before we make 4.18 work.
