From: Chris Wilson @ 2016-07-20 13:11 UTC (permalink / raw)
To: intel-gfx
Now that we have disambuigated ring and engine, we can use the clearer

request.

21 siblings, 1 reply; 72+ messages in thread
From: Chris Wilson @ 2016-07-20 13:11 UTC (permalink / raw)
To: intel-gfx
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().

Space for flushing the GPU cache prior to completing the request is
preallocated and so cannot fail.

From: Chris Wilson @ 2016-07-20 13:12 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.

From: Chris Wilson @ 2016-07-20 13:12 UTC (permalink / raw)
To: intel-gfx
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.

From: Chris Wilson @ 2016-07-20 13:12 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.

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.

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.

From: Chris Wilson @ 2016-07-20 13:12 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 @ 2016-07-20 13:12 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().

You missed a few instances of 'ring' meaning engine:
i915_gem_execbuffer.c: struct intel_engine_cs **ring)
intel_mocs.h:int intel_mocs_init_engine(struct intel_engine_cs *ring);
intel_ringbuffer.c:gen5_seqno_barrier(struct intel_engine_cs *ring)
intel_ringbuffer.h: void (*irq_enable)(struct intel_engine_cs *ring);
intel_ringbuffer.h: void (*irq_disable)(struct intel_engine_cs *ring);
intel_ringbuffer.h: int (*init_hw)(struct intel_engine_cs *ring);
intel_ringbuffer.h: void (*irq_seqno_barrier)(struct intel_engine_cs
*ring);
intel_ringbuffer.h: void (*cleanup)(struct intel_engine_cs *ring);
I think we have to purge every last trace of this usage before using
'ring' as shorthand for 'ringbuf[fer]'.

Doesn't do what it says in the commit message (which sounded like a good
idea). This patch actually just renames the function
intel_init_ring_buffer() to intel_init_engine(). However /most/ of the
code in that function is to do with initialising a ringbuffer!
.Dave.

Oh yes, also there are lots of other things called 'ring' which aren't
ringbuffers, such as an engine:
#define RING_ELSP(ring) _MMIO((ring)->mmio_base + 0x230)
or an engine id:
static i915_reg_t mocs_register(enum intel_engine_id ring, int index)
i915_gem_object_retire__read(struct drm_i915_gem_object *obj, int ring)
int ring = req->engine->id;
or a different structure entirely:
struct drm_i915_error_ring *ring = &error->ring[ring_idx];
I could probably write some Cocci to find-and-rename all the things
called 'ring' that weren't ringbuffers, but it would be easier not to
overload the identifier with a host of different meanings in the first
place. So I think adding any more instances of things called 'ring'
should wait until the name has no other meanings, if ringbuffers are the
thing you want it to unambiguously identify.
.Dave.

We still have a few uses of the identifier "ring" used when referring to
the struct intel_engine_cs (a remanent from when there was only one dual
purpose engine/ringbuffer). Rename all of this to use the familiar
engine so that the separation between the hardware engine and the
ringbuffer containing the commands is clear.
This patch was formed by searching for instances of '\<ring\>' and
changing those found to be referring to an engine. There are quite a few
instances in comments remaining where it is less clear what is
appropriate for the context, the registers still refer to ring (there we
need to check against bspec for any counter-recommendations, but quite a
few registers, like PDP should be engine based, whereas RING_HEAD
probably wants to remain as ring based) and the biggest compromise was
in error capture where we already have a local engine variable and so
finding a good name was trickier.

Don't really like removing the engine = req->engine aliases, but seems
like req->engine is used plenty already. And assuming this was a
mechanical change with no hidden functional changes. Then,

The cocci data would be useful, or sed expression. And would make me
more confident this is pure mechanical work.

If I understood it correctly, result should be equivalent, no
functional changes.

They do, but they shouldn't! The format is discoverable though the

It's a moot point here as the trace output is unchanged, just the trace
point call simplified to match the parent.

Stack deduplication. It'll be clearer eventually.

The code above this line is exact reason why I don't like the a->b->c

I'd just do req->tail = ring->tail and drop the intel_ring_get_tail()
function completely at the most convenient spot which might be around
now before you add some more, currently we only have 5 uses.

Not sure if I would prefer the assignment here still. If overrides
happen from all around the codebase, it'll be harder to come up with
what are the possible values for a vfunc, right?

It's definitely not a default function any more though. It needs to be
conditional on the semaphore setup. We could move the init_semaphores
earlier, and then do
engine->emit_request = i9xx_emit_request;
if (i915.semaphores)
engine->emit_request = gen6_sema_emit_request;
here?

I presume you mean req->engine->x here, not so.y. Is it just the depth
and saving 5 columns? Or something else?

Previousy not done, does it address a bug? It's going to get
overwritten or the render_state has failed to initialize and is
forgotten, no? If it fixes bug, I think the site fondling uninitialized
object should be fixed.

No, nothing is using it indeed. I can't remember why I added it.

Could, but at the moment execlists_context_queue is paired with
execlists_context_unqueue, and we already have
execlists_submit_requests().
Not that we are queueing contexts either.
Perhaps.

Why not to, from here too or in the header then, when they're revamped
in the series? To bring some clarity. Maybe wait and signal in header
too rather.

Just call this "ring" to reduce confusion of renaming the other
variable, then the ring_begin(wait) ring_emit() convention makes more
sense.

Actually noticed later in the series that now the counts are all in the
same function as emitting, comments can be dismissed wrt those cases.

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.

Yeah, that's pretty much what I was after.

Right, GCC doesn't notice the matching rodata == NULL tests. So I guess
this is the easiest way to get rid of the warning.
Or we could treat rodata == NULL as an ENOENT to make GCC shut up. And
then in i915_gem_render_state check for ENOENT? That would simplify the
code too.

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.

Why not -ENOENT anymore, it was propagated up previously.

While you revamp, maybe let the function take req->i915 directly?
Otherwise looks quite good.

I ran my generic Cocci-script for renaming things over the before and
after versions and it didn't find any you'd missed, so:

It can also hurt code efficiency. For example in
int i915_gem_render_state_init(struct drm_i915_gem_request *req)
{
ret = i915_gem_render_state_prepare(req->engine, &so);
...
ret = req->engine->dispatch_execbuffer(req, so.ggtt_offset,
so.rodata->batch_items * 4, I915_DISPATCH_SECURE);
...
if (so.aux_batch_size > 8) {
ret = req->engine->dispatch_execbuffer(req,
(so.ggtt_offset + so.aux_batch_offset),
so.aux_batch_size, I915_DISPATCH_SECURE);
if (ret)
goto out;
}
...
}
The compiler may not -- and in this case, *is not allowed to* -- assume
that req->engine is the same at each callsite. We have passed the
non-const pointer "req" to callees, so it must assume that req->engine
may have been changed and re-fetch it from memory.
By inspection of the generated code, we find that a local for a value
that is used only once is a net loss, twice is breakeven, and three or
more times is a definite win.
And it generally makes the code prettier too :)
.Dave.

Only prettiness really matters here, this emission can be shared for all
contexts with the cache only released under memory pressure. For when we
start caring about the regressions in the GL microbenchmarks...

If submission were to fail we'll probably(!) get a hang later; or else
it might recover(?), though I'm not sure how. We're counting the number
of times this goes wrong, and it's supposed to always be zero. We should
make sure this is all captured in the error state; then if we start
seeing that sometimes it *does* fail then I guess we'll want more
detail. But for now we can just assume it will work.

This doesn't get undone in i915_guc_submission_disable().
That will prevent the runtime fallback from working.

I honestly wasn't sure if that was supported. (runtime enabling would be
nice...)
Would calling a hypothetical intel_execlists_submission_enable() be ok?

I've double checked. The i915_guc_submission_disable() is only called
after failing to enable the guc (in which case we haven't changed
engine->submit_request) or on calling intel_guc_fini() during
module_unload.

Any time the GuC (re)loading process fails, it will revert (forever) to
execlists mode. At present there's no way to switch back to GuC mode
thereafter. Of course, we don't actually *expect* it to fail on a
reload, but we did observe this in action a while back, before we
discovered why reload on resume didn't always work. That's fixed now,
but the fallback is still there just to make sure that any undiscovered
issues around GuC reload don't leave you with a blank screen and an
unusable machine.

Something like that, I guess, although since GuC submission mode is
treated as execlist mode for almost all purposes then _enable() and its
presumed complement _disable() probably aren't the right terms (we don't
want to suggest that enabling GuC mode involves disabling execlist
mode). Perhaps _activate() for a function which simply (re)installs the
vfunc pointers, with no corresponding _deactivate() required, as
activating a new mode implicitly deactivates the old mode (i.e. makes it
unreachable). That little loop can then be moved into its own trivial
guc_submission_activate() function for clarity; and the GuC code would
call intel_execlists_submission_activate() as part of reverting from GuC
to execlists (at the moment it relies on just clearing
enable_guc_submission, but presumably you'd like as few runtime tests of
that as possible).
.Dave.

Do we really get a black screen? I kinda hoped dying with -EIO is still
semi-acceptable. Still not sure maintaining all these fallback paths is
worth it. And -EIO should be good enough to grab logs of why the gpu died
and then reboot.
