Atm, it's possible that the interrupt handler is called when the device
is in D3 or some other low-power state. It can be due to another device
that is still in D0 state and shares the interrupt line with i915, or on
some platforms there could be spurious interrupts even without sharing
the interrupt line. The latter case was reported by Klaus Ethgen using a
Lenovo x61p machine (gen 4). He noticed this issue via a system
suspend/resume hang and bisected it to the following commit:
commit e11aa36230

drm/i915: use runtime irq suspend/resume in freeze/thaw
This is a problem, since in low-power states IIR will always read
0xffffffff resulting in an endless IRQ servicing loop.
Fix this by handling interrupts only when the driver explicitly enables
them and so it's guaranteed that the interrupt registers return a valid
value.
Note that this issue existed even before the above commit, since during
runtime suspend/resume we never unregistered the handler.
v2:
- clarify the purpose of smp_mb() vs. synchronize_irq() in the
code comment (Chris)
v3:
- no need for an explicit smp_mb(), we can assume that synchronize_irq()
and the mmio read/writes in the install hooks provide for this (Daniel)
- remove code comment as the remaining synchronize_irq() is self
explanatory (Daniel)
v4:
- drm_irq_uninstall() implies synchronize_irq(), so no need to call it
explicitly (Daniel)

drm_i915_gem_request and intel_context are both kref reference counted

the context's reference count should be bumped using i915_gem_context_reference.

We need to extend the locking to cover connector->state reading for
atomic drivers, but the above commit was a bit too eager and also
included the fill_modes callback. Which on i915 on old platforms using
load detection needs to acquire modeset locks, resulting in a deadlock
on output probing.

it is enabled by crtc commit.

This patch limits the pixel clock to 13.4 MHz - 266 MHz for i.MX6Q

in the HDMI Transmitter chapter of the respective reference manuals.
Without this patch, when connected to a monitor capable of 2160p60
modes, dw_hdmi will happily report this mode and the IPU code will
cause a division by zero in ipu_di_config_clock when trying to figure
out how to divide the 264 MHz HSP clock down to ~600 MHz.

This patch fixes a bug in the initialization of the pipelines. The
init_pipelines() function was called with a constant value of 0 in the

The correct way is to pass the value that get_first_pipe() returns as the
argument for first_pipe.
This bug appeared in 3.19 (first version with amdkfd) and it causes around 15%
drop in CPU performance of Kaveri (A10-7850).

Commit eab3bbeffd ("drm/atomic: Add drm_crtc_state->active") added the
field to track the DPMS state. However, the Tegra driver was in modified
in parallel and subclasses the CRTC atomic state, so needed to duplicate
the code in the atomic helpers. After the addition of the active_changed
field it became out of sync and doesn't reset it when duplicating state.
This causes a full modeset on things like page-flips, which will in turn
cause warnings due to the VBLANK machinery being disabled when it really
should remain on.

Recent changes in the clock framework have caused a behavioural change
in that clocks that have not had their rate set explicitly will now be
reset to their initial rate (or 0) when the clock is released. This is
triggered in the deferred probing path, resulting in the clock running
at a wrong frequency after the successful probe.
This can be easily fixed by setting the rate explicitly rather than by
relying on the implicit rate inherited by the parent.

This patch is based on exynos-drm-next branch of Inki Dae's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git
DECON(Display and Enhancement Controller) is the new IP
in exynos7 SOC for generating video signals using pixel data.
DECON driver can be used to drive 2 different interfaces on Exynos7:
DECON-INT(video controller) and DECON-EXT(Mixer for HDMI)
The existing FIMD driver code was used as a template to create
DECON driver. Only DECON-INT is supported as of now, and
DECON-EXT support will be added later.
The current version of the driver supports video mode displays.

drm/i915: Restrict GPU boost to the RCS engine
but in reality it undercovered a much older coherency bug. The issue that
boosting the GPU frequency on the BCS ring was masking was that we could
wake the CPU up after completion of a BCS batch and inspect memory prior
to the write cache being fully evicted. In order to serialise the
breadcrumb interrupt (and so ensure that the CPU's view of memory is
coherent) we need to perform a post-sync operation in the MI_FLUSH_DW.
v2: Fix all the MI_FLUSH_DW (bsd plus the duplication in execlists).

As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target
device and not the source. So PCI_DEVFN(2,0) is not correct. Further the
port ID should be enough to identify devices unless they are MFD. The
SB_DevFn was intended to remove ambiguity in case of these MFD devices.
For non MFD devices the recommendation for the target device IP was to
ignore these fields, but not all of them followed the recommendation.
Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so
does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because
of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0).
It turned out that this did not follow the recommendation and expected 0
in this field.
In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for
all devices except target PCI devices.

The Exynos DRM driver doesn't follow the correct API when dealing with
dma_{alloc, mmap, free}_attrs functions and the
DMA_ATTR_NO_KERNEL_MAPPING attribute.
When a IOMMU is not available and the DMA_ATTR_NO_KERNEL_MAPPING is
used, the driver should use the pointer returned by dma_alloc_attr() as
a cookie.
The Exynos DRM driver directly uses the non-requested virtual kernel
address returned by the DMA mapping subsystem. This just works now
because the non-IOMMU codepath doesn't obey DMA_ATTR_NO_KERNEL_MAPPING
but we need to fix it before fixing the DMA layer.

The commit [8975626ea3: drm/cirrus: allow 32bpp framebuffers for

provides the full list of modes up to 1280x1024 while the 32bpp can

We might be able to filter out the invalid modes in mode_valid
callback, but unfortunately the bpp in question can't be referred
there for now (let me know if there is a better way to retrieve the
bpp for the probed fb).
So, instead, this patch adds the bpp module option to specify the
maximal bpp explicitly and limits the resolutions in get_modes
depending on its value.
The default value is set to 24 so that the existing stuff keeps
working. If you need a new 32bpp feature, specify cirrus.bpp=32
option explicitly.

drm: Add multi buffer plane pixel formats
which hasn't seen a lot of review really. The problem is that it's not
a real pixel format, but just a different way to lay out NV12 pixels
in macroblocks, i.e. a tiling format.
The new way of doing this is with the soon-to-be-merged fb modifiers.
This was brough up in some long irc discussion around the entire
topic, as an example of where things have gone wrong. Luckily we can
correct the mistake:
- The kms side support for NV12MT is all dead code because
format_check in drm_crtc.c never accepted NV12MT.
- The gem side for the gsc support doesn't look better: The code
forgets to set the pixel format and makes a big mess with the tiling
mode bits, inadvertedly setting them all.
Conclusion: This never really worked (at least not in upstream) and
hence we can safely correct our mistake here.

You can _never_ assert that a lock is not held, except in some very
restricted corner cases where it's guranteed that your code is running
single-threade (e.g. driver load before you've published any pointers
leading to that lock).
In addition the early return breaks a bunch of testcases since with
highly concurrent hangcheck stress tests the reset fails to work and
the test doesn't recover and time out.
This regression has been introduced in

drm/i915: Remove nested work in gpu error handling
Aside: It is possible to check whether a given task doesn't hold a
lock, but only when lockdep is enabled, using the lockdep_assert_held
stuff.

Currently when a mode is rejected the reason is printed as a raw number.
Having to manually decode that to a enum drm_mode_status value is
tiresome. Have the code do the decoding instead and print the result
in a human readable format.
Just having an array of strings indexed with the mode status doesn't
work since the enum includes negative values. So we offset the status
by +3 which makes all the indexes non-negative. Also add a bit of
paranoia into the code to catch out of bounds accesses in case
someone adds more enum values but forgets to update the code.

Three small fixes that came up during last week, nothing scary:
- Accidently incremented a counter instead of decrementing it (copy-paste error)
- Module parameter of max num of queues must be at least 1 and not 0
- Don't do BUG() as a result from wrong user input

If acceleration is disabled, it does not make sense
to init gpuvm since nothing will use it. Moreover,
if radeon_vm_init() gets called it uses accel to try
and clear the pde tables, etc. which results in a bug.

So after clarification from qcom, it seems mdp4 and mdp5 support
*de*interlacing but not generating an interlaced signal. Which would
explain why interlaced modes never worked properly.
So disable in the one connector which was claiming to support
interlaced.

The gnome-shell wayland compositor triggers a setcrtc with an fb that is
still being rendered, triggering the call to _wait_fence_interruptable().
But a NULL timeout means "don't wait, return -EBUSY if not ready", which
in turn causes the setcrtc to fail.
