6 years agovbo: optimize some display list drawing (v2)
Brian Paul [Fri, 12 Jan 2018 20:18:25 +0000 (13:18 -0700)]
vbo: optimize some display list drawing (v2)

The vbo_save_vertex_list structure records one or more glBegin/End
primitives which all have the same vertex format.

To draw these primitives, we setup the vertex array state, then
issue the drawing command.  Before, the 'start' vertex was typically
zero and we used the vertex array pointer to indicate where the
vertex data starts.

This patch checks if the vertex buffer offset is an exact multiple of
the vertex size.  If so, that means we can use zero-based vertex array
pointers and use the draw's start value to indicate where the vertex
data starts.

This means a series of display list drawing commands may have
identical vertex array state.  This will get filtered out by the
Gallium CSO module so we can issue a tight series of drawing commands
without state changes to the device.

Note that this also works for a series of glCallList commands (not
just one list that contains multiple glBegin/End pairs).

No Piglit or conform changes.

v2: minor fixes suggested by Ian.

may already be using higher sequence numbers than us. In that case, we

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.

st/va: clear pointers for mpeg2 quantiser matrices

This is to fix VA-API issues with GStreamer and MPEG2.
Since gstreamer does not pass quantiser matrices with each frame, invalid
pointers were being passed to the driver. This patch addresses the same.

Revert "ac/shader: gather If TES reads TESSINNER or TESSOUTER"

6 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?).
