Now that tracking is wired up for potentially evictable GEM objects,
wire up shrinker and the remaining GEM bits for unpinning backing pages
of inactive objects.
Disabled by default for now, with an 'enable_eviction' module param to
enable so that we can get some more testing on the range of generations
(and iommu pairings) supported.

Shoot down any mmap's *first* before put_pages(). Also add a WARN_ON
that the object is locked (to make it clear that this doesn't race with
msm_gem_fault()) and remove a redundant WARN_ON (since is_purgable()
already covers that case).

Objects that are potential for swapping out are (1) willneed (ie. if
they are purgable/MADV_WONTNEED we can just free the pages without them
having to land in swap), (2) not on an active list, (3) not dma-buf
imported or exported, and (4) not vmap'd. This repurposes the purged
list for objects that do not have backing pages (either because they
have not been pinned for the first time yet, or in a later patch because
they have been unpinned/evicted.

Currently nearly everything, other than newly allocated objects which
are not yet backed by pages, is pinned and resident in RAM. But it will

Currently these always go together, either when we purge MADV_WONTNEED
objects or when the object is freed. But for unpin, we want to be able
to purge (unmap from iommu) the vma, while keeping the iova range
allocated (so we can remap back to the same GPU virtual address when the
object is re-pinned.

Set the flag vblank_disable_immediate = true to turn off vblank irqs
immediately as soon as drm_vblank_put is requested so that there are
no irqs triggered during idle state. This will reduce cpu wakeups
and help in power saving.
To enable vblank_disable_immediate flag the underlying KMS driver
needs to support high precision vblank timestamping and also a
reliable way of providing vblank counter which is incrementing
at the leading edge of vblank.
This patch also brings in changes to support vblank_disable_immediate
requirement in dpu driver.
Changes in v1:
- Specify reason to add vblank timestamp support. (Rob).
- Add changes to provide vblank counter from dpu driver.
Changes in v2:
- Fix warn stack reported by Rob Clark with v2 patch.
Changes in v3:
- Move back to HW frame counter (Rob).
Changes in v4:
- Frame count mismatch was causing a DRM WARN stack spew.
DPU HW will increment the frame count at the end of
the sync, where as vblank will be triggered at the
fetch_start counter which is calculated as v_total - vfp.
This is to start fetching early for panels with low
vbp w.r.t hw latency lines.
Add logic to detect the line count if it falls between
vactive and v_total then return incremented frame count value.
