loader/dri3: Try to make sure we only process our own NotifyMSC events

We were using a sequence counter value to wait for a specific NotifyMSC
event. However, we can receive events from other clients as well, which
may already be using higher sequence numbers than us. In that case, we
could stop processing after an event from another client, which could
have been received significantly earlier. This would have multiple
undesirable effects:

* The computed MSC and UST values would be lower than they should be
* We could leave a growing number of NotifyMSC events from ourselves and
  other clients in XCB's special event queue

I ran into this with Firefox and Thunderbird, whose VSync threads both
seem to use the same window. The result was sluggish screen updates and
growing memory consumption in one of them.

Fix this by checking the XCB sequence number and MSC value of NotifyMSC
events, instead of using our own sequence number.

v2:
* Use the Present event ID for the sequence parameter of the
  PresentNotifyMSC request, as another safeguard against processing
  events from other clients
* Rebase on drawable mutex changes

i965/miptree: Refactor CCS_E and CCS_D cases in render_aux_usage

This commit unifies the CCS_E and CCS_D cases.  This should fix a couple
of subtle issues.  One is that when you use INTEL_DEBUG=norbc to disable
CCS_E, we don't get the sRGB blending workaround.  By unifying the code,
we give CCS_D that workaround as well.

The second issue fixed by this refactor is that the blending workaround
was appears to be enabled on all gens but really only applies on gen9.
Due to a happy accident in the way code was laid out, it was only
getting enabled on gen9: gen8 and earlier don't support non-zero-one
clear colors, and gen10 supports sRGB for CCS_E so it got caught in the
format_ccs_e_compat_with_miptree case.  This refactor moves it above the
format_ccs_e_compat_with_miptree case so it's an explicit early exit and
makes it explicitly only on gen9.

3 years agofreedreno/ir3: "soft" depth scheduling for SFU instructions
Rob Clark [Thu, 11 Jan 2018 21:08:47 +0000 (16:08 -0500)]
freedreno/ir3: "soft" depth scheduling for SFU instructions

First try with a "soft" depth, to try to schedule sfu instructions
further from their consumers, but fall back to hard depth (which might
result in stalling) if nothing else is avail to schedule.

Previously the consumer of a sfu instruction could end up scheduled
immediately after (since "hard" depth from sfu to consumer would be 0).
This works because legalize pass would insert a (ss) sync bit, but it
is sub-optimal since it would cause a stall.

Instead prioritize other instructions for 4 cycles if they would no
cause a nop to be inserted.  This minimizes the stalling.  There is a
slight penalty in general to overall # of instructions in shader (since
we could end up needing nop's later due to scheduling the "deeper" sfu
consumer later), but ends up being a wash on register pressure.

Overall this seems to be worth a 10+% gain in fps.  Increasing the
"soft" depth of sfu consumer beyond 4 helps a bit in some cases, but 4
seems to be a good trade-off between getting 99% of the gain and not
increasing instruction count of shaders too much.

It's possible a similar approach could help for tex/mem instructions,
but the (sy) sync bit seems to trigger a switch to a different thread-
group to hide memory latency (possibly with some limits depending on
number of registers used?).

freedreno/a5xx: texture tiling

Overall a nice 5-10% gain for most games.  And more for things like
glmark2 texture benchmark.

There are some rough edges.  In particular, the hardware seems to only
support tiling or component swap.  (Ie. from hw PoV, ARGB/ABGR/RGBA/
BGRA are all the same format but with different component swap.)  For
tiled formats, only ARGB is possible.  This isn't a big problem for
*sampling* since we also have swizzle state there (and since
util_format_compose_swizzles() already takes into account the component
order, we didn't use COLOR_SWAP for sampling).  But it is a problem if
you try to render to a tiled BGRA (for example) surface.

The next patch introduces a workaround for blitter, so we can generate
tiled textures in ABGR/RGBA/BGRA, but that doesn't help the render-
target case.  To handle that, I think we'd need to keep track that the
tiled format is different from the linear format, which seems like it
would get extra fun with sampler views/etc.

So for now, disabled by default, enable with FD_MESA_DEBUG=ttile.  In
practice it works fine for all the games I've tried, but makes piglit
grumpy.

3 years agoloader/dri3: Avoid freeing renderbuffers in use
Thomas Hellstrom [Thu, 11 Jan 2018 09:19:23 +0000 (10:19 +0100)]
loader/dri3: Avoid freeing renderbuffers in use

Upon reception of an event that lowered the number of active back buffers,
the code would immediately try to free all back buffers with an id equal to or
higher than the new number of active back buffers.

However, that could lead to an active or to-be-active back buffer being freed,
since the old number of back buffers was used when obtaining an idle back
buffer for use.

This lead to crashes when lowering the number of active back buffers by
transitioning from page-flipping to non-page-flipping presents.

Fix this by computing the number of active back buffers only when trying to
obtain a new back buffer.
