The state stored in this struct is not only the information about the
buffer object, but the ring used to communicate with the hardware. Using
buffer here is overly specific and, for me at least, conflates with the
notion of buffer objects themselves.

Now that we have a clear ring/engine split and a struct intel_ring, we
no longer need the stopgap ringbuf names.

For more consistent oop-naming, we would use intel_ring_verb, so pick
intel_ring_pin() and intel_ring_unpin().

To: intel-gfx
Space for flushing the GPU cache prior to completing the request is
preallocated and so cannot fail - the GPU caches will always be flushed
along with the completed request. This means we no longer have to track
whether the GPU cache is dirty between batches like we had to with the
outstanding_lazy_seqno.
With the removal of the duplication in the per-backend entry points for
emitting the obsolete lazy flush, we can then further unify the
engine->emit_flush.
v2: Expand a bit on the legacy of gpu_caches_dirty

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
Rather than passing a complete set of GPU cache domains for either
invalidation or for flushing, or even both, just pass a single parameter
to the engine->emit_flush to determine the required operations.
engine->emit_flush(GPU, 0) -> engine->emit_flush(EMIT_INVALIDATE)
engine->emit_flush(0, GPU) -> engine->emit_flush(EMIT_FLUSH)
engine->emit_flush(GPU, GPU) -> engine->emit_flush(EMIT_FLUSH | EMIT_INVALIDATE)
This allows us to extend the behaviour easily in future, for example if
we want just a command barrier without the overhead of flushing.

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
If is simpler and leads to more readable code through the callstack if
the allocation returns the allocated struct through the return value.
The importance of this is that it no longer looks like we accidentally
allocate requests as side-effect of calling certain functions.

Both the ->dispatch_execbuffer and ->emit_bb_start callbacks do exactly
the same thing, add MI_BATCHBUFFER_START to the request's ringbuffer -
we need only one vfunc.

remove the function!

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
If we rewrite the I915_WRITE_TAIL specialisation for the legacy
ringbuffer as submitting the request onto the ringbuffer, we can unify
the vfunc with both execlists and GuC in the next patch.
v2: Drop the modulus from the I915_WRITE_TAIL as it is currently being
applied in intel_ring_advance() after every command packet, and add a
comment explaining why we need the modulus at all.

Space reservation is already safe with respect to the ring->size
modulus, but hardware only expects to see values in the range
0...ring->size-1 (inclusive) and so requires the modulus to prevent us
writing the value ring->size instead of 0. As this is only required for
the register itself, we can defer the modulus to the register update and
not perform it after every command packet. We keep the
intel_ring_advance() around in the code to provide demarcation for the
end-of-packet (which then can be compared against intel_ring_begin() as
the number of dwords emitted must match the reserved space).
v2: Assert that the ring size is a power-of-two to match assumptions in
the code. Simplify the comment before writing the tail value to explain
why the modulus is necessary.

Move request submission from emit_request into its own common vfunc
from i915_add_request().
v2: Convert I915_DISPATCH_flags to BIT(x) whilst passing
v3: Rename a few functions to match.
v4: Reenable execlists submission after disabling guc.
v5: Be aware that everyone calls i915_guc_submission_disable()!

With adding engine->submit_request, we now have a bunch of functions
with similar names used at different stages of the execlist submission.
Try a different coat of paint, to hopefully reduce confusion between the
requests, intel_engine_cs and the actual execlists submision process.

Rather than pass in the num_dwords that the caller wishes to use after
the signal command packet, split the breadcrumb emission into two phases
and have both the signal and breadcrumb individiually acquire space on
the ring. This makes the interface simpler for the reader, and will
simplify for patches.

As GEN6+ is now a simple variant on the basic breadcrumbs + tail write,
reuse the common code.

As gen6_emit_request() only differs from i9xx_emit_request() when
semaphores are enabled, only use the specialised vfunc in that scenario.
v2: Reorder semaphore init so as to keep engine->emit_request default
vfunc selection compact.

Now that we use the same vfuncs for emitting the batch buffer in both
execlists and legacy, the golden render state initialisation is
identical between both.
v2: gcc wants so.ggtt_offset initialised (even though it is not used)

GCC was inlining the init and setup functions, but was getting itself
confused into thinking that variables could be used uninitialised. If we
do the inline for gcc, it is happy! As a bonus we shrink the code.

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
Now that emitting requests is identical between legacy and execlists, we
can use the same function to build up the ring for submitting to either
engine. (With the exception of i915_switch_contexts(), but in time that
will also be handled gracefully.)

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
Since requests can no longer be generated as a side-effect of
intel_ring_begin(), we know that the seqno will be unchanged during
ring-emission. This predicatablity then means we do not have to check
for the seqno wrapping around whilst emitting the semaphore for
engine->sync_to().

From: Chris Wilson @ 2016-08-02 21:50 UTC (permalink / raw)
To: intel-gfx
In order to be more consistent with the rest of the request construction
and ring emission, use the common names for the ring and request.
Rather than using signaler_req, waiter_req, and intel_ring *wait, we use
plain req and ring.
