[PATCH i-g-t 0/5] Initial dmem cgroup support

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

This series introduces library support for some trivial cgroup v2
dmem manipulation.

It also adds a test for the library support itself and then an
xe test where cgroup functionality is exercised. In particular
lowering the max allocated amount of vram beyond what's already
allocated.

That functionality is not in the kernel yet, but a series for it
is pending.

Patch 1 adds library functionality.
Patch 2 adds a test for the library functionality. It's device
      agnostic.
Patch 3 adds a function to get the xe driver cgroup controller
      region name for an xe device VRAM region. Also library
      functionality.
Patch 4 extends the library vm_bind functionality, pending
      completion of https://patchwork.freedesktop.org/patch/714000/?series=163579&rev=3
Patch 5 adds the xe cgroup test (some KMD functionality still missing).
