For most drivers, drm_fence_init is followed by drm_fence_emit
immediately. But for our driver, they are done separately. We also
don't know the fence seqno until drm_fence_emit.

This is motivated by having meaningful ftrace events, but it also
fixes use cases where dma_fence_is_later is called, such as in
sync_file_merge.
In other drivers, fence creation and cmdbuf submission normally
happen atomically,
mutex_lock();
fence = dma_fence_create(..., ++timeline->seqno);
submit_cmdbuf();
mutex_unlock();
and have no such issue. But in our driver, because most ioctls
queue commands into ctrlq, we do not want to grab a lock. Instead,
we set seqno to 0 when a fence is created, and update it when the
command is finally queued and the seqno is known.

The 50 ms default timeout waiting for vblanks is too small
for the first vblank from the ST-Ericsson MCDE display
controller over DSI. Presumably this is because the DSI
display is command-mode only and the state machine will
take some time setting up its state for the first display
update, and we hit a timeout. 100 ms makes it pass without
problems.

It is the expectation of existing userspace (X11 + Mesa, in
particular) that jobs submitted to the kernel against a shared BO will
get implicitly synchronized by their submission order. If we want to
allow clever userspace to disable implicit synchronization, we should
do that under its own submit flag (as amdgpu and lima do).
Note that we currently only implicitly sync for the rendering pass,
not binning -- if you texture-from-pixmap in the binning vertex shader
(vertex coordinate generation), you'll miss out on synchronization.
Fixes flickering when multiple clients are running in parallel,
particularly GL apps and compositors.
v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

The compute shader dispatch interface is pretty simple -- just pass in
the regs that userspace has passed us, with no CLs to run. However,
with no CL to run it means that we need to do manual cache flushing of
the L2 after the HW execution completes (for SSBO, atomic, and
image_load_store writes that are the output of compute shaders).
This doesn't yet expose the L2 cache's ability to have a region of the
address space not write back to memory (which could be used for
shared_var storage).
So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
the ES31 tests), and on the kernel side on 7278 (failing atomic
compswap tests in a way that doesn't reproduce on simpenrose).
v2: Fix excessive allocation for the clean_job (reported by Dan
Carpenter). Keep refs on jobs until clean_job is finished, to
avoid spurious MMU errors if the output BOs are freed by userspace
before L2 cleaning is finished.

The CL submission had two jobs embedded in an exec struct. When I
added TFU support, I had to replicate some of the exec stuff and some

what was in exec should just be in the two CL jobs, and it would let
us share a lot more code between the 4 queues.

Our driver makes a typical use of CMA, with GEM object allocated as
GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops
instead of duplicating them.
Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op
which sets per-object funcs (drm_cma_gem_default_funcs), we can also
get rid of free_object_unlocked and gem_vm_ops, which are superseded
by the object funcs.
