The current userptr page population will defer work to a work item if
needed to avoid ever taking the mmap_sem in the direct call path. With
the more fine-grained locking in etnaviv this isn't needed anymore, so
a future commit will simplify this code.
Add a lockdep annotation to validate the assumption that the mmap_sem
can be taken in the direct call path.

Userptr, prime and shmem buffer objects have different lock ordering
requirements. This is mostly due to the fact that we don't allow to mmap
userptr buffers, so we won't ever end up in our fault handler for those,
so some of the code paths are never called with the mmap_sem held.
To avoid lockdep false positives, split them up into different lock classes.

Exynos DRM IPP subsystem is in fact non-functional and frankly speaking
dead-code. This patch clearly marks that Exynos DRM IPP subsystem is
broken and never really functional. It will be replaced by a completely
rewritten API.
Exynos DRM IPP user-space API can be obsoleted for the following
reasons:
1. Exynos DRM IPP user-space API can be optional in Exynos DRM, so
userspace should not rely that it is always available and should have
a software fallback in case it is not there.
2. The only mode which was initially semi-working was memory-to-memory
image processing. The remaining modes (LCD-"writeback" and "output")
were never operational due to missing code (both in mainline and even
vendor kernels).
3. Exynos DRM IPP mainline user-space API compatibility for
memory-to-memory got broken very early by commit 083500baefd5 ("drm:
remove DRM_FORMAT_NV12MT", which removed the support for tiled formats,
the main feature which made this API somehow useful on Exynos platforms
(video codec that time produced only tiled frames, to implement xvideo
or any other video overlay, one has to de-tile them for proper
display).
4. Broken drivers. Especially once support for IOMMU has been added,
it revealed that drivers don't configure DMA operations properly and in
many cases operate outside the provided buffers trashing memory around.
5. Need for external patches. Although IPP user-space API has been used
in some vendor kernels, but in such cases there were additional patches
applied (like reverting mentioned 083500baefd5 patch) what means that
those userspace apps which might use it, still won't work with the
mainline kernel version.
We don't have time machines, so we cannot change it, but Exynos DRM IPP
extension should never have been merged to mainline in that form.
Exynos IPP subsystem and user-space API will be rewritten, so remove
current IPP core code and mark existing drivers as BROKEN.

Looking at a CI failure with an ominous line of
[ 362.550715] hangcheck current seqno ffffff6b, last ffffff8c, hangcheck ffffff6b [6016 ms], inflight 118
with no apparent cause for the seqno to be negative, left me wondering
if someone had scribbled over the HWSP. So include the HWSP in the
engine dump to see if there are more signs of random scribbling.
v2: Fix row pointer, i is now incremented by 8 so doesn't need scaling
by 8, and we don't need to keep volatile here as the status_page isn't
marked up as volatile itself.

We should only attempt to remove requests from the execution queue that
are on the execution queue. These are the requests that have been
assigned a global_seqno, so we can assert that we only attempt to remove
requests with a nonzero global_seqno. Afterwards we assert that we
remove them in order, i.e. the global_seqno matches the engine's seqno,
but that leaves a small loophole for an unattached request on an unused
engine.
We can then make the same assertion on queuing the request to the
execution engine, it must have a zero global_seqno or else we are queuing
the same request twice.

We have plenty of global registers and whatnot programmed without
any further locking by the modeset code. Currently non-bocking
modesets are allowed to execute in parallel which could corrupt
said registers.
To avoid the problem let's run all non-blocking modesets on an
ordered workqueue. We still put page flips etc. to system_unbound_wq
allowing page flips on one pipe to execute in parallel with page flips
or a modeset on a another pipe (assuming no known state is shared
between them, at which point they would have been added to the same
atomic commit and serialized that way).
Blocking modesets are already serialized with each other by
connection_mutex, and thus are safe. To serialize them with
non-blocking modesets we just flush the workqueue before executing
blocking modesets.

Gen9+ need to disable GMBUS clock gating when doing multi part
transfers. Otherwise clock gating will kick in when GMBUS is in
the WAIT state and presumably that will corrupt the transfer.
This is documented as Display WA #0868.
Apparently older hardware doesn't allow clock gating in the WAIT
state and thus are unaffected by this problem.

Our QA reported a problem caused by movntdqa instructions. Currently,
the KVM hypervisor doesn't support VEX-prefix instructions emulation.
If users passthrough a GPU to guest with vfio option 'x-no-mmap=on',
then all access to the BARs will be trapped and emulated. The KVM
hypervisor would raise an inertal error to qemu which cause the guest
killed. (Since 'movntdqa' ins is not supported.)
This patch try not to enable movntdqa optimization if the driver is
running in hypervisor guest.

of typed mmio reg with real offset.
Old vgpu_vreg(offset) helper is used only for offset now with new
vgpu_vreg_t(reg) is used for i915_reg_t only. Convert left usage
of that to new helper.
Also fixed left KASAN warning issues caused by previous hack.

observed igt drv_module_reload test case failure on 4.15.0
rc2 kernel with panic due to no active pipe available.
the gpu will reset during unload/load and make pipe config reg
lost which can cause kernel panic issue happen.
this patch is to move pipe enabling to emulate_mointor_status_chagne
to handle vgpu reset case as well.

We don't need any active planes during load detection, so just disable
them all. This saves us from having to come up with a suitable
framebuffer. And we also avoid leaving sprite/cursor planes on and
potentially presenting them at a peculiar location during the load
detection.
Changes since v1 (Maarten):
- Add missing call to add_all_affected_planes.

Current code advertises (on the modifiers blob property) support for CCS
modifier for pipe C on GLK, only to reject it later when validating the
request before the atomic commit.
This fixes the tests igt@kms_ccs@pipe-c-*, which should skip on GLK for
pipe C (see bug 104096).

validate_fbc never fails a modeset. It's simply used to decide whether
to use FBC or not. Calling it validate_fbc might be confusing to some so
rename it to should_enable_fbc.
With that let's also remove the DC_STATUS return code and return bool
and make enable_fbc a void function since we never check it's return
value and probably never want to anyways.
