I would like if these kernel patches are accepted by everyone, If yes,
when they can be upstream.
I have a MR for libdrm to support drm nodes type up to 2^MINORBITS
nodes which can work with these patches,
https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/305
Thanks!

We do need patches to stop trying to infer the node type from the

in a few places in libdrm.
That sounds like a really good idea to me as well.
But what do we do with DRM_MAX_MINOR? Change it or keep it and say apps
should use drmGetDevices2() like Emil suggested?
DRM_MAX_MINOR has been bumped to 64 now.
With the new minor allocation scheme, DRM_MAX_MINOR is meaningless
because there is no "max minor per type" concept anymore: the minor no
longer contains the type.
So I'd suggest leaving it as-is (so that old apps still continue to
work on systems with < 64 devices like they do today) and mark it as
deprecated.
Sounds like a plan to me.

Christian.
