drm/syncobj: Add a signal ioctl (v3)
This IOCTL provides a mechanism for userspace to trigger a sync object
directly. There are other ways that userspace can trigger a syncobj
such as submitting a dummy batch somewhere or hanging on to a triggered
sync_file and doing an import. This just provides an easy way to
manually trigger the sync object without weird hacks.
The motivation for this IOCTL is Vulkan fences. Vulkan lets you create
a fence already in the signaled state so that you can wait on it
immediatly without stalling. We could also handle this with a new
create flag to ask the driver to create a syncobj that is already
signaled but the IOCTL seemed a bit cleaner and more generic.

drm/syncobj: Allow wait for submit and signal behavior (v5)
Vulkan VkFence semantics require that the application be able to perform
a CPU wait on work which may not yet have been submitted. This is
perfectly safe because the CPU wait has a timeout which will get
triggered eventually if no work is ever submitted. This behavior is
advantageous for multi-threaded workloads because, so long as all of the
threads agree on what fences to use up-front, you don't have the extra
cross-thread synchronization cost of thread A telling thread B that it
has submitted its dependent work and thread B is now free to wait.
Within a single process, this can be implemented in the userspace driver
by doing exactly the same kind of tracking the app would have to do
using posix condition variables or similar. However, in order for this
to work cross-process (as is required by VK_KHR_external_fence), we need
to handle this in the kernel.
This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which
instructs the IOCTL to wait for the syncobj to have a non-null fence and
then wait on the fence. Combined with DRM_IOCTL_SYNCOBJ_RESET, you can
easily get the Vulkan behavior.
v2:
- Fix a bug in the invalid syncobj error path
- Unify the wait-all and wait-any cases
v3:
- Unify the timeout == 0 case a bit with the timeout > 0 case
- Use wait_event_interruptible_timeout
v4:
- Use proxy fence
v5:
- Revert to a combination of v2 and v3
- Don't use proxy fences

This patch uses the new mode_valid callback (many thanks to

The video processor supports a tiled version of the NV12 format,
known as NV12MT in V4L2 terms. The support was removed in commit
083500baefd5f4c215a5a93aef2492c1aa775828 due to not being a real
pixel format, but rather NV12 with a special memory layout.
With the introduction of FB modifiers, we can now properly support
this format again.
Tested with a hacked up modetest from libdrm's test suite on
an ODROID-X2 (Exynos4412).

- moved down all DSI ops - they require exynos_dsi_disable function

returns if panel is attached,
- DSI attach/detach callbacks attaches/detaches DRM panel and sets

Notable changes:
- Improvements to CONFIG option handling to make it harder for users to
shoot themselves in the foot due to kernel misconfiguration.
- Tweaked GEM object population, so that userspace can take considerate
action when memory allocation fails, rather than waking the raging OOM

AMD has started cleaning the pipe and sending patches from their internal
development to the upstream community.
The plan as I understand it is to first get all the non-dGPU patches to
upstream and then move to upstream dGPU support.
The patches here are relevant only for Kaveri and Carrizo.
The following is a summary of the changes:
- Add new IOCTL to set a Scratch memory VA
- Update PM4 headers for new firmware that support scratch memory
- Support image tiling mode
- Remove all uses of BUG_ON
- Various Bug fixes and coding style fixes
