10 years agoi965/blorp: do not use unnecessary hw-blending support
Topi Pohjolainen [Mon, 27 Jan 2014 08:50:01 +0000 (10:50 +0200)]
i965/blorp: do not use unnecessary hw-blending support

This is really not needed as blorp blit programs already sample
XRGB normally and get alpha channel set to 1.0 automatically by
the sampler engine. This is simply copied directly to the payload
of the render target write message and hence there is no need for
any additional blending support from the pixel processing pipeline.

The blending formula is anyway broken for color components, it
multiplies the color component with itself (blend factor is the
component itself).
Alpha blending in turn would not fix the alpha to one independent
of the source but simply used the source alpha as is instead
(1.0 * src_alpha + 0.0 * dst_alpha).

Quoting Eric:

 "If we want to actually make the no-alpha-bits-present thing work,
  we need to override the bits in the surface state or in the
  generated code.  In the normal draw path, it's done for sampling
  by the swizzling code in brw_wm_surface_state.c, and the blending
  overrides is just to fix up the alpha blending stage which
  doesn't pay attention to that for the destination surface."

If one modifies piglit test gl-3.2-layered-rendering-blit to use
color component values other than zero or one, this change will
kick in on IVB. No regressions on IVB.

This is effectively revert of c0554141a9b831b4e614747104dcbbe0fe489b9d:

    i965/blorp: Support overriding destination alpha to 1.0.

    Currently, Blorp requires the source and destination formats to be
    equal.  However, we'd really like to be able to blit between XRGB and
    ARGB formats; our BLT engine paths have supported this for a long time.

    For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
    interpreted as 1.0.  For XRGB -> ARGB, we need to smash the alpha
    channel to 1.0 when writing the destination colors.  This is fairly
    straightforward with blending.

    For now, this code is never used, as the source and destination formats
    still must be equal.  The next patch will relax that restriction.

    NOTE: This is a candidate for the 9.1 branch.

Rob Clark [Wed, 29 Jan 2014 22:18:49 +0000 (17:18 -0500)]
freedreno/a3xx/compiler: new compiler

The new compiler generates a dependency graph of instructions, including
a few meta-instructions to handle PHI and preserve some extra
information needed for register assignment, etc.

The depth pass assigned a weight/depth to each node (based on sum of
instruction cycles of a given node and all it's dependent nodes), which
is used to schedule instructions.  The scheduling takes into account the
minimum number of cycles/slots between dependent instructions, etc.
Which was something that could not be handled properly with the original
compiler (which was more of a naive TGSI translator than an actual
compiler).

The register assignment is currently split out as a standalone pass.  I
expect that it will be replaced at some point, once I figure out what to
do about relative addressing (which is currently the only thing that
should cause fallback to old compiler).

There are a couple new debug options for FD_MESA_DEBUG env var:

  optmsgs - enable debug prints in optimizer
  optdump - dump instruction graph in .dot format, for example:

http://people.freedesktop.org/~robclark/a3xx/frag-0000.dot.png
http://people.freedesktop.org/~robclark/a3xx/frag-0000.dot

At this point, thanks to proper handling of instruction scheduling, the
new compiler fixes a lot of things that were broken before, and does not
appear to break anything that was working before[1].  So even though it
is not finished, it seems useful to merge it in it's current state.

i965: Update 3DSTATE_{DEPTH,STENCIL,...}_BUFFER and such for Broadwell.

The amount of cut and paste from Gen7 is rather ugly, and should
probably be cleaned up in the future.  Even the Gen7 code is in need of
some tidying though; many of the function parameters aren't used on
platforms that use level/layer rather than tile offsets.  Tidying both
can be left to a future patch series.  This at least gets things going.

v2: Rebase on Paul's rename of NumLayers -> MaxNumLayers.

v3: Shift QPitch by 2 when storing it in the packet.  Bits 14:0 store
    bits 16:2 of the actual value.  Fixes tests.

v4: Add missing stencil buffer QPitch.

glcpp: Don't enter lexer's NEWLINE_CATCHUP start state for single-line comments

In commit 6005e9cb28 a new start state of NEWLINE_CATCHUP was added to the
lexer. This start state is used whenever the lexer is emitting a NEWLINE token
to emit additional NEWLINE tokens for any newline characters that were skipped
by an immediately preceding multi-line comment.

However, that commit erroneously entered the NEWLINE_CATCHUP state for
single-line comments. This is not desired since in the case of a single-line
comment, the lexer is not emitting any NEWLINE token. The result is that the
lexer will remain in the NEWLINE_CATCHUP state and proceed to fail to emit a
NEWLINE token for the subsequent newline character, (since the case to match \n expects only the INITIAL start state).

The fix is quite simple, remove the "BEGIN NEWLINE_CATCHUP" code from the
single-line comment case, (preserving it only in exactly the cases where the
lexer is actually emitting a NEWLINE token).

Many thanks to Petri Latvala for reporting this bug and for providing the
minimal test case to exercise it. The bug showed up only with a multi-line
comment which was followed immediately by a single-line comment (without any
intervening newline), such as:

/*
        */ // Kablam!

Since 6005e9cb28, and before this commit, that very innocent-looking
combination of comments would yield a parse failure in the compiler.
