i965/fs: Use the source type when looking for UD negations in copy prop

There can be problems with floats and conditional modifiers when
copy-propagating a negated UD source.  The problem arises when a source
modifier is applied to a UD value.  In this case, a 33-bit representation
is internally used.  If you do the following:

   1: mov foo:UD 7U
   2: mov bar:UD -foo:UD
   3: mov out:F bar:UD

the out register will have the value (float)(unt32_t)-7 which is some very
large floating-point number.  However, if we allow copy-propagation of the
second mov, we get

   1: mov foo:UD 7U
   3: mov out:f -bar:UD

and, since the negation is computed in 33-bits, we get a value of -7.0f
which is clearly not the same.  This is a similar problem if the
instruction has a conditional modifier where the 33-bit value is used in
the comparison and not the 32-bit version.

Previously, we checked the source to be copied for the negate and then
checked the source being propagated to for the type.  This isn't quite what
we want because we are really just looking for negated UD sources.  A check
later in the file ensures that both ends of the propagate have the right
type so it works.  However, if we relax the restriction that both ends of
the propagation have the same type, it ends up causing us to bail early in
cases we don't want.

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.

9 years agoglx: Create proper server dependency for GLX_EXT_create_context_es2_profile

glx: Create proper server dependency for GLX_EXT_create_context_es2_profile

Previously GLX_EXT_create_context_es2_profile was marked as "direct
only" so that it would not depend on server support.  Since the
extension required functions that are part of
GLX_ARB_create_context_profile, support for the EXT was disabled if the
ARB was not supported.

This was complete rubbish.  If the server supported the ARB but not the
EXT, sending a request with GLX_CONTEXT_ES2_PROFILE_BIT_EXT would result
in GLXBadProfileARB.

Instead of the misguided hack, make GLX_EXT_create_context_es2_profile
properly depend on server support by not marking it as "direct only."

v2: Modify the algorithm. Instead of iterating in reverse through blocks and

on top of Ken's patching modifying is_last_send

Some comment typo fixes and rewordings.
Whitespace
Move the optimization pass outside of the optimize loop

v4: Some cosmetic changes requested from Ken. These changes ensured that the
optimization function always returned true when an optimization occurred, and
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.

This patch shouldn't actually have any impact on the current code since the EOT

FS_OPCODE_FB_WRITE. The next patch however will introduce an optimization
