660e855813 amdgpu: use drm sync objects for shared semaphores (v6)
This creates a new command submission chunk for amdgpu
to add in and out sync objects around the submission.

Sync objects are managed via the drm syncobj ioctls.

The command submission interface is enhanced with two new
chunks, one for syncobj pre submission dependencies,
and one for post submission sync obj signalling,
and just takes a list of handles for each.

This is based on work originally done by David Zhou at AMD,
with input from Christian Konig on what things should look like.

In theory VkFences could be backed with sync objects and
just get passed into the cs as syncobj handles as well.

NOTE: this interface addition needs a version bump to expose
it to userspace.

TODO: update to dep_sync when rebasing onto amdgpu master.
(with this - r-b from Christian)

v1.1: keep file reference on import.
v2: move to using syncobjs
v2.1: change some APIs to just use p pointer.
v3: make more robust against CS failures, we now add the
wait sems but only remove them once the CS job has been
submitted.
v4: rewrite names of API and base on new syncobj code.
v5: move post deps earlier, rename some apis
v6: lookup post deps earlier, and just replace fences
in post deps stage (Christian)

6f0308ebc1 amdgpu/cs: split out fence dependency checking (v2)
This just splits out the fence depenency checking into it's
own function to make it easier to add semaphore dependencies.

a682169891 imx-drm: cleanups and YUV 4:2:0 memory read/write reduction support
- Remove counter load enable form PRE, which has no effect.
 - Add support for setting the double read/write reduction flag in channel
   parameter memory. This can be used to save some memory bandwidth when
   capturing in YUV 4:2:0 chroma subsampled formats.
 - Allocate DMA channel structures as needed, most of the 64 channels are
   unused or even reserved.
 - Remove unused interrupt busy waiting routine.
 - Set VDIC field order for both AUTO and MAN inputs simultaneously as
   both can't be active at the same time.

7249e3d64e sun4i-drm changes for 4.13
An unusually big pull request for this merge window, with three notable
 features:
   - V3s display engine support. This is especially notable because it uses
     a different display engine used on the newer Allwinner SoCs (H3, A64
     and the likes) that will be quite easily supported now.
   - HDMI support for the old Allwinner SoCs. This is enabled only on the
     A10s for now, but should be really easy to extend to deal with A10, A20
     and A31
   - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
     etc.). It currently ignores the second pipeline, but we can use the
     dual-pipelines bindings. This will be useful to enable the display
     pipeline while we work on the dual-pipeline.

ae9d042143 drm: mxsfb_crtc: Reset the eLCDIF controller
According to the eLCDIF initialization steps listed in the MX6SX
Reference Manual the eLCDIF block reset is mandatory.

Without performing the eLCDIF reset the display shows garbage content
when the kernel boots.

In earlier tests this issue has not been observed because the bootloader
was previously showing a splash screen and the bootloader display driver
does properly implement the eLCDIF reset.

Add the eLCDIF reset to the driver, so that it can operate correctly
independently of the bootloader.

Tested on a imx6sx-sdb board.

ab4fe3e1f9 drm/amdgpu: fix missed gpu info firmware when cache firmware during S3
gpu_info firmware is released after data is used. But when system enters into
suspend, upper class driver will cache all firmware names. At that time,
gpu_info will be failing to load. It seems an upper class issue, that we should
not release gpu_info firmware until device finished.

Sync objects are new toplevel drm object, that contain a
pointer to a fence. This fence can be updated via command
submission ioctls via drivers.

There is also a generic wait obj API modelled on the vulkan
wait API (with code modelled on some amdgpu code).

These objects can be converted to an opaque fd that can be
passes between processes.

v3: cleanups from danvet, rebase on drm_fops rename
check fd_flags is 0 in ioctls.

later semantics which seem in the end to be cleaner.

d0b1d259a4 drm/vc4: Fix resource leak in 'vc4_get_hang_state_ioctl()' in error handling path
If one 'drm_gem_handle_create()' fails, we leak somes handles and some
memory.

In order to fix it:
  - move the 'free(bo_state)' at the end of the function so that it is also
    called in the eror handling path. This has the side effect to also try
    to free it if the first 'kcalloc' fails. This is harmless.
  - add a new label, err_delete_handle, in order to delete already
    allocated handles in error handling path
  - remove the now useless 'err' label

The way the code is now written will also delete the handles if the
'copy_to_user()' call fails.
