Subject: [RFC] dmisc cgroups controller
Date: Fri, 14 Aug 2026 11:32:54 +0200	[thread overview]
Message-ID: <894f9d44eae62aee5762495b4f90f9bdd2b5585d.camel@linux.intel.com> (raw)

Hi!

We (drm/xe GPU driver) have a use-case where we have a very limited
number of a particular device resource (CLOS slots) that we potentially
want to expose to unprivlieged processes for reservation / allocation.
We want to be able to restrict per cgroups the number of CLOS slots
that are available for reservation / allocation.

This is not a good fit for the misc controller since these resource
types may be added and removed similar to dmem regions. Neither is it a
good fit for the dmem controller.

Would a dmisc controller be suitable here? It would be similar to the
misc countroller but with dynamic addition and removal of resource
types similar to the dmem controller.

Any input greatly appreciated.

Thanks,
Thomas
