05adb1850a Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued
Pull in latest drm-next from Dave Airlie to get at all the drm-misc
goodies, specifically:
- dma_fence error state handling rework (Chris needs that for error
  recovery)
- crc support locking changes (Tomeu's i915 crc patches need that).

af3076e67c drm: flip cirrus driver status to "obsolete".
Also update Kconfig help text, explaining things:

Cirrus is obsolete, the hardware was designed in the 90ies
and can't keep up with todays needs.  More background:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/

Better alternatives are:
  - stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
  - qxl (DRM_QXL, qemu -vga qxl, works best with spice)
  - virtio (VIRTIO_GPU), qemu -vga virtio)

8201c1fad4 drm/i915: Clip the partial view against the object not vma
The VMA is later clipped against the vm_area_struct before insertion of
the faulting PTE so we are free to create the partial view as we desire.
If we use the object as the extents rather than the area, this partial
can then be used for other areas.

68f458eec7 drm: Schedule the output_poll_work with 1s delay if we have delayed event
Instead of scheduling the work to handle the initial delayed event, use 1s
delay.

This delay should not be needed, but Optimus/nouveau will fail in a
mysterious way if the delayed event is handled as soon as possible like it
is done in drm_helper_probe_single_connector_modes() in case the poll
was enabled before.

Reverting 339fd36238 would give back the 10 sec (!) delay to handle the
delayed event. Adding 1sec delay to the poll_work is enough to work around
the issue in Optimus setups and gives shorter response on handling the
initial delayed event.

cea84d16c3 drm/i915: Remove the rounding down of the gen4+ fence region
Restricting the fence to the end of the previous tile-row breaks access

944397f04f drm/i915: Store required fence size/alignment for GGTT vma
The fence size/alignment is a combination of the vma size plus object
tiling parameters. Those parameters are rarely changed, making the fence
size/alignemnt roughly constant for the lifetime of the VMA. We can
simplify subsequent calculations by precalculating the size/alignment
required for GGTT vma taking fencing into account (with an update if we
do change the tiling or stride).

9631739f81 drm/i915/gvt: cleanup GFP flags
In gvt, almost all memory allocations are in sleepable contexts. It's
fault-prone to use GFP_ATOMIC everywhere. Replace it with GFP_KERNEL
wherever possible.

f0a8b49c03 drm/bridge: analogix dp: Fix runtime PM state on driver bind
Analogix_dp_bind() can be called from component framework, which doesn't
guarantee proper runtime PM state of the device during bind operation,
so ensure that device is runtime active before doing any register access.
This ensures that the power domain, to which DP module belongs, is turned
on. While at it, also fix the unbalanced call to phy_power_on() in
analogix_dp_bind() function.

This patch solves the following kernel oops on Samsung Exynos5250 Snow
board:

03551e971f drm/i915/gvt: cleanup opregion memory allocation code
According to the spec, ACPI OpRegion must be placed at a physical address
below 4G. That is, for a vGPU it must be associated with a GPA below 4G,
but on host side, it doesn't matter where the backing pages actually are.
So when allocating pages from host, the GFP_DMA32 flag is unnecessary.

Also the allocation is from a sleepable context, so GFP_ATOMIC is also
unnecessary.

This patch also removes INTEL_GVT_OPREGION_PORDER and use get_order()
instead.

The vgpu->running_workload_num is used to determine whether a vgpu has
any workload running or not. So we should make sure the workload is
really done before we dec running_workload_num. Function
complete_current_workload is not the right place to do it, since this
function is still processing the workload. This patch move the dec op
afterward.

3e70c5d6ea drm/i915/gvt: verify functions types in new_mmio_info()
The current prototype of new_mmio_info() uses void* for parameters read
and write, which are functions with precise calling conventions
(argument types and return type). Write down these conventions in
new_mmio_info() definition.

This has been reported by the following warnings when clang is used to
build the kernel:

    drivers/gpu/drm/i915/gvt/handlers.c:124:21: error: pointer type
    mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,
    void *, unsigned int)') [-Werror,-Wpointer-type-mismatch]
            info->read = read ? read : intel_vgpu_default_mmio_read;
                              ^ ~~~~   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    drivers/gpu/drm/i915/gvt/handlers.c:125:23: error: pointer type
    mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,
    void *, unsigned int)') [-Werror,-Wpointer-type-mismatch]
            info->write = write ? write : intel_vgpu_default_mmio_write;
                                ^ ~~~~~   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This allows the compiler to detect that sbi_ctl_mmio_write() returns a
"bool" value instead of an expected "int" one. Fix this.

3806a271bf Merge tag 'drm-misc-next-2016-12-30' of git://anongit.freedesktop.org/git/drm-misc into drm-next
First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
  in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
  dma-buf kerneldoc patches

It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during
this time might be useful.

I'd also like to backmerge -rc2+this into drm-intel next week, we have
quite a pile of patches waiting for the stuff in here.
