9 years agoi965/skl: Add the header for constant loads outside of the generator
Neil Roberts [Tue, 24 Mar 2015 15:52:20 +0000 (15:52 +0000)]
i965/skl: Add the header for constant loads outside of the generator

Commit 5a06ee738 added a step to the generator to set up the message
header when generating the VS_OPCODE_PULL_CONSTANT_LOAD_GEN7
instruction. That pseudo opcode is implemented in terms of multiple
actual opcodes, one of which writes to one of the source registers in
order to set up the message header. This causes problems because the
scheduler isn't aware that the source register is written to and it
can end up reorganising the instructions incorrectly such that the
write to the source register overwrites a needed value from a previous
instruction. This problem was presenting itself as a rendering error
in the weapon in Enemy Territory: Quake Wars.

Since commit 588859e1 there is an additional problem that the double
register allocated to include the message header would end up being
split into two. This wasn't happening previously because the code to
split registers was explicitly avoided for instructions that are
sending from the GRF.

This patch fixes both problems by splitting the code to set up the
message header into a new pseudo opcode so that it will be done
outside of the generator. This new opcode has the header register as a
destination so the scheduler can recognise that the register is
written to. This has the additional benefit that the scheduler can
optimise the message header slightly better by moving the mov
instructions further away from the send instructions.

On Skylake it appears to fix the following three Piglit tests without
causing any regressions:

 gs-float-array-variable-index
 gs-mat3x4-row-major
 gs-mat4x3-row-major

I think we actually may need to do something similar for the fs
backend and possibly for message headers from regular texture sampling
but I'm not entirely sure.

v2: Make sure the exec-size is retained as 8 for the mov instruction
    to initialise the header from g0. This was accidentally lost
    during a rebase on top of 07c571a39fa1.
    Split the patch into two so that the helper function is a separate
    change.
    Fix emitting the MOV instruction on Gen7.

false when one did not. This behavior did not exist with the original patch. As
a result, having the separate helper function which Matt did not like no longer
made sense, and so now I believe everyone should be happy.

i965/fs: Only emit FS_OPCODE_PLACEHOLDER_HALT if there are discards

Based originally on a patch from Ken in May 2014 of the same title. Things
changed enough that I didn't feel comfortable leaving his authorship.

v2: Replace fp->UsesKill with wm_prog_data->uses_kill. Since Ken took the time
to also explain the difference to me, here is his explanation for posterity:

"fp->UsesKill indicates that a ARB_fragment_program shader uses the KIL
instruction, or that a GLSL shader uses the "discard" insntruction
(which are analogous).

On Gen4-5, we sometimes have to simulate OpenGL's "Alpha Test" feature
by emitting shader code that implicitly does a "discard" instruction.

In the key setup, we do:

   /* key->alpha_test_func means simulating alpha testing via discards,
    * so the shader definitely kills pixels.
    */
   prog_data.uses_kill = fp->program.UsesKill || key->alpha_test_func;

Even though the shader may not technically contain a "discard", we need
to act as if it does.

I've also been trying to move the i965 state setup code to use
brw_wm_prog_key for everything, rather than poking at core Mesa's
gl_program/gl_fragment_program/gl_shader/gl_shader_program structures.

i965/skl: Use an exec size of 8 to initialise the message header

Commit e93566a15c61c33faa changed the message header code needed to
make Skylake use SIMD4x2 so that it uses a register with width 4
instead of 8 as the source register in the send message. However it
also changed the width for the dest in the MOV instruction which is
used to initialise the header register with the values from g0. The
width of the destination is used to determine the exec size in
brw_set_dest so this would end up making the MOV have an exec size of
4. I think this would end up leaving the top half of the register
uninitialised. The top half of the header has meaningful values so
this probably isn't a good idea.

This patch just casts the dest register for the MOV instruction back
to a vec8 to fix it. It doesn't cause any changes to a Piglit run.

i965/fs: Always invert predicate of SEL with swapped arguments

zero, so that value could be used in the SEL instruction instead of
potentially loading 0.0 into a register.

This change switched the order of the arguments to the SEL, and, for

only be inverted for the == case.  Clearly, it should always be
inverted.

i965: Implement proper workaround for Gen4 GPU CONSTANT_BUFFER hangs.

I finally managed to dig up some information on our mysterious GPU hangs.
A wiki page from the Crestline validation team mentions that they found
a GPU hang in "Serious Sam 2" (on Windows) with remarkably similar
conditions to the ones we've seen in Google Chrome and glmark2.

Apparently, if WM_STATE has "PS Use Source Depth" enabled, CC_STATE has
most depth state disabled, and you issue a CONSTANT_BUFFER command and
immediately draw, the depth interpolator makes a small mistake that
leads to hangs.

Most of the traces I looked at contained a CONSTANT_BUFFER packet
immediately followed by 3DPRIMITIVE, or at least very few packets.
It appears they also have "PS Use Source Depth" enabled - either at the
hang, or a little before it.  So I think this is our bug.

The workaround is to emit a non-pipelined state packet after issuing a
CONSTANT_BUFFER packet.  This is really similar to the workaround I
developed in commit c4fd0c9052dd391d6f2e9bb8e6da209dfc7ef35b.
