Chris Wilson 3607e1e9ba drm/i915/gt: Add a routine to iterate over the pagetables of a GTT
In the next patch, we will want to look at the dma addresses of
individual page tables, so add a routine to iterate over them.

Thomas Hellström 1c4dbe056d drm/i915: Reference objects on the ww object list
Since the ww transaction endpoint easily end up far out-of-scope of
the objects on the ww object list, particularly for contending lock
objects, make sure we reference objects on the list so they don't
disappear under us.

This comes with a performance penalty so it's been debated whether this
is really needed. But I think this is motivated by the fact that locking
is typically difficult to get right, and whatever we can do to make it
simpler for developers moving forward should be done, unless the
performance impact is far too high.

Thomas Hellström b4b9731b02 drm/i915: Simplify userptr locking
Use an rwlock instead of spinlock for the global notifier lock
to reduce risk of contention in execbuf.

Protect object state with the object lock whenever possible rather
than with the global notifier lock

Don't take an explicit page_ref in userptr_submit_init() but rather
call get_pages() after obtaining the page list so that
get_pages() holds the page_ref. This means we don't need to call
userptr_submit_fini(), which is needed to avoid awkward locking
in our upcoming VM_BIND code.

Maarten Lankhorst cf3e3e86d7 drm/i915: Use ttm mmap handling for ttm bo's.
Use the ttm handlers for servicing page faults, and vm_access.

We do our own validation of read-only access, otherwise use the
ttm handlers as much as possible.

Because the ttm handlers expect the vma_node at vma->base, we slightly
need to massage the mmap handlers to look at vma_node->driver_private
to fetch the bo, if it's NULL, we assume i915's normal mmap_offset uapi
is used.

This is the easiest way to achieve compatibility without changing ttm's
semantics.

Thomas Hellström 213d509277 drm/i915/ttm: Introduce a TTM i915 gem object backend
Most logical place to introduce TTM buffer objects is as an i915
gem object backend. We need to add some ops to account for added
functionality like delayed delete and LRU list manipulation.

Initially we support only LMEM and SYSTEM memory, but SYSTEM
(which in this case means evicted LMEM objects) is not
visible to i915 GEM yet. The plan is to move the i915 gem system region
over to the TTM system memory type in upcoming patches.

We set up GPU bindings directly both from LMEM and from the system region,
as there is no need to use the legacy TTM_TT memory type. We reserve
that for future porting of GGTT bindings to TTM.

Remove the old lmem backend.

Merge tag 'exynos-drm-next-for-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Two cleanups
- These patches make Exynos DRM driver to use pm_runtime_resume_and_get()
  function instead of m_runtime_get_sync() to deal with usage counter.
  pm_runtime_get_sync() increases the usage counter even when it failed,
  which could make callers to forget to decrease the usage counter.
  pm_runtime_resume_and_get() decreases the usage counter regardless of
  whether it failed or not.

Alex Deucher 2c1b1ac708 drm/amdgpu/vcn: drop gfxoff control for VCN2+
Drop disabling of gfxoff during VCN use.  This allows gfxoff
to kick in and potentially save power if the user is not using
gfx for color space conversion or scaling.

VCN1.0 had a bug which prevented it from working properly with
gfxoff, so we disabled it while using VCN.  That said, most apps
today use gfx for scaling and color space conversion rather than
overlay planes so it was generally in use anyway. This was fixed
on VCN2+, but since we mostly use gfx for color space conversion
and scaling and rapidly powering up/down gfx can negate the
advantages of gfxoff, we left gfxoff disabled. As more
applications use overlay planes for color space conversion
and scaling, this starts to be a win, so go ahead and leave
gfxoff enabled.

Note that VCN1.0 uses vcn_v1_0_idle_work_handler() and
vcn_v1_0_ring_begin_use() so they are not affected by this
patch.

This is wrong as if we have a multi to single pipe change or
vice versa, that would be treated as a same Dbuf state and thus
no changes required, so we don't get Mbus updated, causing issues.
Solution: check also mbus_join, in addition to slices mask.

source when intel_psr is already enabled.

- intel_psr_pause(): Pause current PSR. It deactivates current psr state.
- intel_psr_resume(): Resume paused PSR. It activates paused psr state.

v2: Address Jose's review comment.
  - Remove unneeded changes around the intel_psr_enable().
  - Add intel_psr_post_exit() which processes waiting until PSR is idle
    and WA for SelectiveFetch.
v3: Address Jose's review comment.
  - Rename intel_psr_post_exit() to intel_psr_wait_exit_locked().

  - In order to avoid the scenario of PSR is not active but there is a
    scheduled psr->work, it changes the check routine of intel_psr_pause()
    for PSR's enablement from "psr->active" to "psr->enable".

Dingchen (David) Zhang caa18dd6dd drm/amd/display: force CP to DESIRED when removing display
[WHY]
- Commit from userspace could cause link stream to disable and hdcp
auth to reset when the HDCP has already been enabled at the moment.
CP should fall back to DESIRED from ENABLED in such cases.
- This change was previously reverted due to a regression caused, which
has now been cleared.

[HOW]
In hdcp display removal, change CP to DESIRED if at the moment CP
is ENABLED before the auth reset and removal of linked list element.
