Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.11.
Nothing too major, the tinydrm and mmu-less support should make
writing smaller drivers easier for some of the simpler platforms, and
there are a bunch of documentation updates.
Intel grew displayport MST audio support which is hopefully useful to
people, and FBC is on by default for GEN9+ (so people know where to
look for regressions). AMDGPU has a lot of fixes that would like new
firmware files installed for some GPUs.
Other than that it's pretty scattered all over.
I may have a follow up pull request as I know BenH has a bunch of AST
rework and fixes and I'd like to get those in once they've been tested
by AST, and I've got at least one pull request I'm just trying to get
the author to fix up.

Merge tag 'v4.10-rc8' into drm-next
Linux 4.10-rc8
Backmerge Linus rc8 to fix some conflicts, but also
to avoid pulling it in via a fixes pull from someone.
Pull locking updates from Ingo Molnar:
"The main changes in this cycle were:
- Implement wraparound-safe refcount_t and kref_t types based on
generic atomic primitives (Peter Zijlstra)
- Improve and fix the ww_mutex code (Nicolai Hähnle)
- Add self-tests to the ww_mutex code (Chris Wilson)
- Optimize percpu-rwsems with the 'rcuwait' mechanism (Davidlohr
Bueso)
- Micro-optimize the current-task logic all around the core kernel
(Davidlohr Bueso)
- Tidy up after recent optimizations: remove stale code and APIs,
clean up the code (Waiman Long)
- ... plus misc fixes, updates and cleanups"

Greatly improves the chances of recovering the GPU from a CTXSW_TIMEOUT.
Tested with piglit's arb_shader_image_load_store-atomicity, which causes
GR to hang in such a way that recovery failed (CTXSW_TIMEOUT continually
re-triggers).

This will serve as a basis for implementing some improvements to how
we recover the GPU from channel errors.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
The previous commit simply changes the interface, but should result in
the same behaviour as previously. This commit has been split out from
it as it can result in a different channel being selected.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
FIFO gives us load/save/switch status, and we need to be able to determine
which direction a "switch" is failing during channel recovery.
In order to do this, we apparently need to query the engine itself.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
There are instances (such as non-recoverable GPU page faults) where
NVKM decides that a channel's context is no longer viable, and will
be removed from the runlist.
This commit notifies the owner of the channel when this happens, so
it has the opportunity to take some kind of recovery action instead
of hanging.

If the led class registration fails, we free drm->led but do not reset
it to NULL, which means that the suspend/resume/fini function will act
as if everything went well in init() and will likely crash the kernel.
This patch adds the missing drm->led = NULL.

This will allow the DRM to share memory objects between clients later
down the track.
For the moment, the only immediate benefit is less logic required to
handle suspend/resume.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
We never have any need for a double-linked list here, and as there's
generally a large number of these objects, replace it with a single-
linked list in order to save some memory.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
We want a supervisor client of NVKM (such as the DRM) to be able to
allow sharing of resources (such as memory objects) between clients.
To allow this, the supervisor creates all its clients as children of
itself, and will use an upcoming ioctl to permit sharing.
Currently it's not possible for indirect clients to use subclients.
Supporting this will require an additional field in the main ioctl.
This isn't important currently, but will need to be fixed for virt.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
The fields were already in struct nvkm_oclass for some reason (probably
as an accidental left-over).
Preparation for supporting subclients.
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
nvkm_object::client refers to the client that created the object, which,
is currently always the same as the ioctl caller.
Upcoming patches introduce the concept of subclients, where a parent is
able to access the object trees of its children, making the above no
longer true.
