9 years agoi965: Use predicate enable bit for conditional rendering w/o stalling
Neil Roberts [Tue, 4 Nov 2014 19:15:00 +0000 (19:15 +0000)]
i965: Use predicate enable bit for conditional rendering w/o stalling

Previously whenever a primitive is drawn the driver would call
_mesa_check_conditional_render which blocks waiting for the result of
the query to determine whether to render. On Gen7+ there is a bit in
the 3DPRIMITIVE command which can be used to disable the primitive
based on the value of a state bit. This state bit can be set based on
whether two registers have different values using the MI_PREDICATE
command. We can load these two registers with the pixel count values
stored in the query begin and end to implement conditional rendering
without stalling.

Unfortunately these two source registers were not in the whitelist of
available registers in the kernel driver until v3.19. This patch uses
the command parser version from intel_screen to detect whether to
attempt to set the predicate data registers.

The predicate enable bit is currently only used for drawing 3D
primitives. For blits, clears, bitmaps, copypixels and drawpixels it
still causes a stall. For most of these it would probably just work to
call the new brw_check_conditional_render function instead of
_mesa_check_conditional_render because they already work in terms of
rendering primitives. However it's a bit trickier for blits because it
can use the BLT ring or the blorp codepath. I think these operations
are less useful for conditional rendering than rendering primitives so
it might be best to leave it for a later patch.

v2: Use the command parser version to detect whether we can write to
    the predicate data registers instead of trying to execute a
    register load command.
v3: Simple rebase
v4: Changes suggested by Kenneth Graunke: Split the
    load_64bit_register function out to a separate patch so it can be
    a shared public function. Avoid calling
    _mesa_check_conditional_render if we've already determined that
    there's no query object. Some styling fixes.

9 years agonir/nir: Use a linked list instead of a hash set for use/def sets
Jason Ekstrand [Fri, 24 Apr 2015 17:16:27 +0000 (10:16 -0700)]
nir/nir: Use a linked list instead of a hash set for use/def sets

This commit switches us from the current setup of using hash sets for
use/def sets to using linked lists.  Doing so should save us quite a bit of
memory because we aren't carrying around 3 hash sets per register and 2 per
SSA value.  It should also save us CPU time because adding/removing things
from use/def sets is 4 pointer manipulations instead of a hash lookup.

Running shader-db 50 times with USE_NIR=0, NIR, and NIR + use/def lists:

   GLSL IR Only:        586.4 +/- 1.653833
   NIR with hash sets:  675.4 +/- 2.502108
   NIR + use/def lists: 641.2 +/- 1.557043

I also ran a memory usage experiment with Ken's patch to delete GLSL IR and
keep NIR.  This patch cuts an aditional 42.9 MiB of ralloc'd memory over
and above what we gained by deleting the GLSL IR on the same dota trace.

On the code complexity side of things, some things are now much easier and
others are a bit harder.  One of the operations we perform constantly in
optimization passes is to replace one source with another.  Due to the fact
that an instruction can use the same SSA value multiple times, we had to
iterate through the sources of the instruction and determine if the use we
were replacing was the only one before removing it from the set of uses.
With this patch, uses are per-source not per-instruction so we can just
remove it safely.  On the other hand, trying to iterate over all of the
instructions that use a given value is more difficult.  Fortunately, the
two places we do that are the ffma peephole where it doesn't matter and GCM
where we already gracefully handle duplicates visits to an instruction.

Another aspect here is that using linked lists in this way can be tricky to
get right.  With sets, things were quite forgiving and the worst that
happened if you didn't properly remove a use was that it would get caught
in the validator.  With linked lists, it can lead to linked list corruption
which can be harder to track.  However, we do just as much validation of
the linked lists as we did of the sets so the validator should still catch
these problems.  While working on this series, the vast majority of the
bugs I had to fix were caught by assertions.  I don't think the lists are
going to be that much worse than the sets.

Commit 94ee908448 added a header size parameter to the function to
create the LOAD_PAYLOAD instruction. However this broke
opt_sampler_eot which manually constructs the instruction and so
wasn't setting the header_size. This ends up making the parameters for
the send message all have the wrong location and it all falls apart.

to be the intent, we can probably make this optional later if
someone makes hw that cares and writes a driver.
