2abe2f8446 drm/i915: Allow fence allocations to fail
If a fence allocation fails in a blocking context, we will sleep on the
fence as a last resort. We can therefore allow ourselves to fail and
sleep on the fence instead of triggering a system-wide oom. This allows
us to throttle malicious clients that are consuming lots of system
resources by capping the amount of memory used by fences.

e30a7581bf drm/i915: Mark up potential allocation paths within i915_sw_fence as might_sleep
As kmalloc is allowed to block (if given the right flags), mark up the
two i915_sw_fence routines that may call kmalloc as potential sleeping
routines.

d7dc4131eb drm/i915: Don't check #active_requests from i915_gem_wait_for_idle()
i915_gem_wait_for_idle() is called from inside the shrinker, to ensure
that we drain the last resources from the GPU in dire circumstances (OOM).
As we may allocate whilst building a request, it is then possible to hit
the shrinker with a request under construction, and so we must account
for the incomplete request whilst waiting. In particular, we
preincrement (in reserve_engine) the i915->gt.active_requests counter
and mark the GPU as busy, therefore we can not use that counter for
shortcircuiting the wait-for-idle.

7d622351c9 drm/i915/fence: Use rcu to defer freeing of irq_work
It is illegal to perform an immediate free of the struct irq_work from
inside the irq_work callback (as irq_work_run_list modifies work->flags
after execution of the work->func()). As we use the irq_work to
coordinate the freeing of the callback from two different softirq paths,
we need to defer the kfree from inside our irq_work callback, for which
we can use kfree_rcu.

1875fe7ba1 drm/i915: Downgrade misleading "Memory usable" message
It never meant what it said, as it was always the total size of the
Global GTT and not a limit upon memory usage. Originally it served as a
quick guide to the largest batch that could be submitted by userspace,
an approximation to its maximum RSS, but was phrased badly. Today with
the 48b ppgtt, it is even more meaningless. Replace with a more specific
debug message; those wanting to know how much "video ram" they have
should consult the userspace libraries for the relevant approximation.

v2: Rebase

On Tonga VF, there're 2 sources updating wptr registers for
sdma3: 1) polling mem and 2) doorbell. When doorbell and polling
mem are both enabled on sdma3, there will be collision hit in
occasion between those two sources when ucode and h/w are doing
the updating on wptr register in parallel. Issue doesn't happen
on CP GFX/Compute since CP drops all doorbell writes when VF is
inactive. So enable polling mem and don't use doorbell for SDMA3.

b92326a040 drm/i915: Only report a wakeup if the waiter was truly asleep
If we attempt to wake up a waiter, who is currently checking the seqno
it will be in the TASK_INTERRUPTIBLE state and ttwu will report success.
However, it is actually awake and functioning -- so delay reporting the
actual wake up until it sleeps. This fixes some spurious claims of
missed_breadcrumbs when running under heavy load; i.e. sufficient load to
preempt away the newly woken waiter before they complete their checks.
However, it does so at the cost of a rare false negative; where the
waiter changes between the check and ttwu -- the only way to fix that
would be to extend the reporting from ttwu where the check could be done
atomically.

v2: Defend against !CONFIG_SMP
v3: Don't filter out calls to wake_up_process
v4: Drop risky microoptimisation to skip wakeups

Testcase: igt/drv_missed_irq # sanity check we do detect missed_breadcrumb()

776bc27fd8 drm/i915: Stop listening to request resubmission from the signaler kthread
The intent here was that we would be listening to
i915_gem_request_unsubmit in order to cancel the signaler quickly and
release the reference on the request. Cancelling the signaler is done
directly via intel_engine_cancel_signaling (called from unsubmit), but
that does not directly wake up the signaling thread, and neither does
setting the request->global_seqno back to zero wake up listeners to the
request->execute waitqueue. So the only time that listening to the
request->execute waitqueue would wake up the signaling kthread would be
on the request resubmission, during which time we would already receive
wake ups from rejoining the global breadcrumbs wait rbtree.

Trying to wake up to release the request remains an issue. If the
signaling was cancelled and no other request required signaling, then it
is possible for us to shutdown with the reference on the request still
held. To ensure that we do not try to shutdown, leaking that request, we
kick the signaling threads whenever we disarm the breadcrumbs, i.e. on
parking the engine when idle.

v2: We do need to be sure to release the last reference on stopping the
kthread; asserting that it has been dropped already is insufficient.

461bd6227e drm/i915/gvt/fb_decoder: Fix out-of-bounds read
In case function skl_format_to_drm returns -EINVAL, fmt turns into a huge
number as fmt is of type u32, hence there is an out-of-bounds read when
using fmt as an index for array skl_pixel_formats at line 225:
plane->bpp = skl_pixel_formats[fmt].bpp;

Fix this by comparing the value returned by function skl_format_to_drm
against the size of array skl_pixel_formats, so in case it is greater than
or equal to the number of items contained in skl_pixel_formats, print an
error message and return -EINVAL.

950bc137c3 drm/armada: implement primary plane update
Implement primary plane update without having to go through a modeset
to achieve that; the hardware does not require such complexity.  This
means we treat the primary plane as any other, allowing the format,
size, position and scaling to be updated via the normal plane ioctls.

This also allows us to seemlessly disable and re-enable the primary
plane when (eg) displaying full-frame video without any graphic
clipping the overlaid video - which saves wasting memory bandwidth
needlessly verifying that the colorkey is indeed filling the entire
primary plane.

7bfab1ec45 drm/armada: use drm_plane_helper_check_state()
Use drm_plane_helper_check_state() to check the overlay plane state
rather than drm_plane_helper_check_update(), as:

(1) using drm_plane_helper_check_state() provides a better migration
    path to atomic modeset
(2) it avoids needless copies of drm rectangle structures, and so is
    more efficient.

7a1530d7f9 intel/atomic: Stop updating legacy fb parameters
Even fbc isn't using this stuff anymore, so time to remove it.

Cleaning up one small piece of the atomic conversion cruft at the time
...

Quick explanation on why the plane->fb assignment is ok to delete: The
core code takes care of the refcounting and legacy ->fb pointer
updating, but drivers are allowed to update it ahead of time. Most
legacy modeset drivers did that as part of their set_config callback
(since that's how the legacy/crtc helpers worked). In i915 we only
need that to make the fbc code happy.

v2: don't nuke the assignement of intel_crtc->config, I accidentally
set CI ablaze :-) Spotted by Maarten. And better explain why nuking
the ->fb assignement shouldn't set off alarm bells.

b68763741a drm/i915: Restore GT performance in headless mode with DMC loaded
It seems that the DMC likes to transition between the DC states a lot when
there are no connected displays (no active power domains) during command
submission.

This activity on DC states has a negative impact on the performance of the
chip with huge latencies observed in the interrupt handlers and elsewhere.
Simple tests like igt/gem_latency -n 0 are slowed down by a factor of
eight.

Work around it by introducing a new power domain named,
POWER_DOMAIN_GT_IRQ, associtated with the "DC off" power well, which is
held for the duration of command submission activity.

CNL has the same problem which will be addressed as a follow-up. Doing
that requires a fix for a DC6 context corruption problem in the CNL DMC
firmware which is yet to be released.

v2:
 * Add commit text as comment in i915_gem_mark_busy. (Chris Wilson)
 * Protect macro body with braces. (Jani Nikula)

v3:
 * Add dedicated power domain for clarity. (Chris, Imre)
 * Commit message and comment text updates.
 * Apply to all big-core GEN9 parts apart for Skylake which is pending DMC
   firmware release.

v4:
 * Power domain should be inner to device runtime pm. (Chris)
 * Simplify NEEDS_CSR_GT_PERF_WA macro. (Chris)
 * Handle async DMC loading by moving the GT_IRQ power domain logic into
   intel_runtime_pm. (Daniel, Chris)
 * Include small core GEN9 as well. (Imre)

v5
 * Special handling for async DMC load is not needed since on failure the
   power domain reference is kept permanently taken. (Imre)

v6:
 * Drop the NEEDS_CSR_GT_PERF_WA macro since all firmwares have now been
   deployed. (Imre, Chris)

9428088c90 drm/qxl: reapply cursor after resetting primary
QXL associates mouse state with its primary plane.

Destroying a primary plane and putting a new one in place has the side
effect of destroying the cursor as well.

This commit changes the driver to reapply the cursor any time a new
primary is created. It achieves this by keeping a reference to the
cursor bo on the qxl_crtc struct.

This fix is very similar to

commit 4532b241a4 ("drm/qxl: reapply cursor after SetCrtc calls")

which got implicitly reverted as part of implementing the atomic
modeset feature.

Currently on every submission, we recalculate the ELSP register offset
for the engine, after chasing the pointers to find the iomem base. Since
this is fixed for the lifetime of the driver, record the offset in the
execlists struct.

In practice the difference is negligible, it just happens to remove 27
bytes of eyesore pointer dancing from next to the hottest instruction
(which is itself due to stalling for a cache miss) in perf profiles of
the execlists_submission_tasklet().

v2: Trim off one more elsp local.

e2189dd078 drm/i915: Refactor common list iteration over GGTT vma
In quite a few places, we have a list iteration over the vma on an
object that only want to inspect GGTT vma. By construction, these are
placed at the start of the list, so we have copied that knowledge into
many callsites. Pull that knowledge back to i915_vma.h and provide a
for_each_ggtt_vma() to tidy up the code.

v2: Add a backreference from vma_create() to remind ourselves why we put
ggtt vma at the head of the obj->vma_list (and ppgtt vma at the tail).
v3: Fixup s/vma/V/

1b1f42d8fd drm: move amd_gpu_scheduler into common location
This moves and renames the AMDGPU scheduler to a common location in DRM
in order to facilitate re-use by other drivers. This is mostly a straight
forward rename with no code changes.

One notable exception is the function to_drm_sched_fence(), which is no
longer a inline header function to avoid the need to export the
drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

510353a637 drm/bridge: analogix dp: Fix runtime PM state in get_modes() callback
get_modes() callback might be called asynchronously from the DRM core and
it is not synchronized with bridge_enable(), which sets proper runtime PM
state of the main DP device. Fix this by calling pm_runtime_get_sync()
before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and
analogix_dp_transfer() to ensure that main DP device is runtime active
when doing any access to its registers.

7125397b82 drm/i915: Track GGTT writes on the vma
As writes through the GTT and GGTT PTE updates do not share the same
path, they are not strictly ordered and so we must explicitly flush the
indirect writes prior to modifying the PTE. We do track outstanding GGTT
writes on the object itself, but since the object may have multiple GGTT
vma, that is overly coarse as we can track and flush individual vma as
required.

Whilst here, update the GGTT flushing behaviour for Cannonlake.

v2: Hard-code ring offset to allow use during unload (after RCS may have
been freed, or never existed!)

010e3e68cd drm/i915: Remove vma from object on destroy, not close
Originally we translated from the object to the vma by walking
obj->vma_list to find the matching vm (for user lookups). Now we process
user lookups using the rbtree, and we only use obj->vma_list itself for
maintaining state (e.g. ensuring that all vma are flushed or rebound).
As such maintenance needs to go on beyond the user's awareness of the
vma, defer removal of the vma from the obj->vma_list from i915_vma_close()
to i915_vma_destroy()

7a8b705350 Revert "drm/i915: Display WA #1133 WaFbcSkipSegments:cnl, glk"
This reverts commit 8f067837c4.

HSD says "WA withdrawn. It was causing corruption with some images.
WA is not strictly necessary since this bug just causes loss of FBC
compression with some sizes and images, but doesn't break anything."

5bfd40139d drm/vc4: Fix false positive WARN() backtrace on refcount_inc() usage
With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
passed a refcount object that has its counter set to 0. In this driver,
this is a valid use case since we want to increment ->usecnt only when
the BO object starts to be used by real HW components and this is
definitely not the case when the BO is created.

Fix the problem by using refcount_inc_not_zero() instead of
refcount_inc() and fallback to refcount_set(1) when
refcount_inc_not_zero() returns false. Note that this 2-steps operation
is not racy here because the whole section is protected by a mutex
which guarantees that the counter does not change between the
refcount_inc_not_zero() and refcount_set() calls.

ef78970ace drm/i915: Call i915_gem_init_userptr() before taking struct_mutex
We don't need struct_mutex to initialise userptr (it just allocates a
workqueue for itself etc), but we do need struct_mutex later on in
i915_gem_init() in order to feed requests onto the HW.

This should break the chain

120a264f9c drm/exynos: gem: Drop NONCONTIG flag for buffers allocated without IOMMU
When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver
are contiguous, because of the underlying dma_alloc_attrs() function
provides only such buffers. In such case it makes no sense to keep
BO_NONCONTIG flag for the allocated GEM buffers. This allows to avoid
failures for buffer contiguity checks in the subsequent operations on GEM
objects.

dm_log_to_buffer logs unconditionally, so calling it directly resulted
in the main message being logged even when the event type isn't enabled
in the event mask.

To fix this, use the new dm_logger_append_va API.

Fixes spurious messages like

 [drm] {1920x1200, 2080x1235@154000Khz}

in dmesg when a mode is set.

v2:
* Use new dm_logger_append_va API, fixes incorrect va_list usage in v1

Rework *_set_mc_special_registers for the other architectures to

Change the logic to check before access instead of after incrementing.
It's fine if j reaches max after we're done. This allows the last entry

f59548c882 drm/amdgpu:fix NULL pointer access during drv remove
NULL pointer is because original logic will step into
set_pde_pte() even after the gart.ptr is freed due to
there are twice gart_unbind() on all gart area.

also, there are other minor fixes:
1,since gart_init only create dummy page, the corresponding
gart_fini shouldn't do more like unbinding all GART, this is
unnecessary because in driver fini stage all GART unbinding
had already been done during each IP's SW_FINI (GMC's
SW_FINI is the last one called), so remove the step
for the GART unbinding in gart_fini().

2,gart_fini() is already invoked during each GMC IP's gart_fini
routine,e.g. gmc_vx_0_gart_fini(), so no need to manually
call it during ttm_fini().

3,amdgpu_gem_force_release() should be put ahead of
amdgpu_vm_manager_fini()

b674f1edc9 drm/amd/display: Change frontend/backend programming sequence
This is a follow-up to the following change:

Yongqiang Sun: Program front end first when set mode.

Due to pipe-splitting features, how we handle stream enabling and
disabling needs to change.

In the case of pipe split disable, two planes need to be combined back
into the same stream. This needs to be done before any stream
programming happens.

The previous patch addresses this, but breaks cross-platform
compatibility. It's not guaranteed that a dc commit will be called
separately to program planes and streams.

Therefore, we handle the combined commit case by doing plane programming
both before and after stream programming, to handle pipe split disable
and plane enable respectively.

SMU can future lower voltages in long idle case when all display is off.

If all display output is turned off via DPMS, send display_count = 0
after all output are turned off.

otherwise send display_count msg before turning on display to make sure
SMU exit S0i2 state.  before is not neccessary as we are out of S0i2
when driver execute code, but send message before anyways for correctness.

Also, when doing a stream update we would program regamma for all pipes,
even thos that are not yet powered on. This resulted in never setting
