i965/sync: Replace prefix 'intel_sync' -> 'intel_gl_sync'

I'm about to implement DRI2_Fenc in intel_syncobj.c.  To prevent
madness, we need to prefix functions for GL_ARB_sync with 'gl' and
functions for DRI2_Fence with 'dri'. Otherwise, the file will become
a jumble of similiarly named functions.

For example:
    old-name:      intel_client_wait_sync()
    new-name:      intel_gl_client_wait_sync()
    soon-to-come:  intel_dri_client_wait_sync()

I wrote this renaming commit separately from the commit that implements
DRI2_Fence because I wanted the latter diff to be reviewable.

Jason Ekstrand [Wed, 25 Mar 2015 00:00:04 +0000 (17:00 -0700)]
i965/fs: Rework the fs_visitor LOAD_PAYLOAD instruction

The newly reworked instruction is far more straightforward than the
original.  Before, the LOAD_PAYLOAD instruction was lowered by a the
complicated and broken-by-design pile of heuristics to try and guess
force_writemask_all, exec_size, and a number of other factors on the
sources.

Instead, we use the header_size on the instruction to denote which sources
are "header sources".  Header sources are required to be a single physical
hardware register that is copied verbatim.  The registers that follow are
considered the actual payload registers and have a width that correspond's
to the LOAD_PAYLOAD's exec_size and are treated as being per-channel.  This
gives us a fairly straightforward lowering:

 1) All header sources are copied directly using force_writemask_all and,
    since they are guaranteed to be a single register, there are no
    force_sechalf issues.

 2) All non-header sources are copied using the exact same force_sechalf
    and force_writemask_all modifiers as the LOAD_PAYLOAD operation itself.

 3) In order to accommodate older gens that need interleaved colors,
    lower_load_payload detects when the destination is a COMPR4 register
    and automatically interleaves the non-header sources.  The
    lower_load_payload pass does the right thing here regardless of whether
    or not the hardware actually supports COMPR4.

This patch commit itself is made up of a bunch of smaller changes squashed
together.  Individual change descriptions follow:

i965/fs: Rework fs_visitor::LOAD_PAYLOAD

   We rework LOAD_PAYLOAD to verify that all of the sources that count as
   headers are, indeed, exactly one register and that all of the non-header
   sources match the destination width.  We then take the exec_size for
   LOAD_PAYLOAD directly from the destination width.

i965/fs: Make destinations of load_payload have the appropreate width

i965/fs: Rework fs_visitor::lower_load_payload

   v2: Don't allow the saturate flag on LOAD_PAYLOAD instructions

i965/fs_cse: Support the new-style LOAD_PAYLOAD

i965/fs_inst::is_copy_payload: Support the new-style LOAD_PAYLOAD

i965/fs: Simplify setup_color_payload

   Previously, setup_color_payload was a a big helper function that did a
   lot of gen-specific special casing for setting up the color sources of
   the LOAD_PAYLOAD instruction.  Now that lower_load_payload is much more
   sane, most of that complexity isn't needed anymore.  Instead, we can do
   a simple fixup pass for color clamps and then just stash sources
   directly in the LOAD_PAYLOAD.  We can trust lower_load_payload to do the
   right thing with respect to COMPR4.

glsl: don't lower fragdata array if the output data types don't match

Commit 7e414b58640aee6e243d337e72cea290c354f632 broke the gl_FragData array
into separate gl_FragData[i] variables, so drivers can eliminate useless
writes to gl_FragData improving their performance.

The problem occurs when GLSL IR code is linked in the following case:

* The FS output variable base data type does not match gl_FragData one (float
  vector)
* The FS output variable is replaced by gl_out_FragDataX because of commit
  7e414b58640aee6 with X from 0 to GL_MAX_DRAW_BUFFERS.

Then the FS output variable base data type is lost in the resulting GLSL IR,
making that the driver does a wrong assignment to gl_out_FragData components
because of unmatching data types.

This patch reverts the fragdata array lowering when the output var base data type
doesn't match gl_out_FragData, i.e., when output variable base data type is
not a float or a float vector.

This patch fixes 250 dEQP tests (tested in an Intel Haswell machine)

dEQP-GLES3.functional.fragment_out.random.* (22 failed tests)

9 years agomesa: Restore functionality to dispatch sanity test
Ian Romanick [Wed, 29 Apr 2015 18:53:18 +0000 (11:53 -0700)]
mesa: Restore functionality to dispatch sanity test

Along with a couple secondary goals, the dispatch sanity test had two
major, primary goals.

1. Ensure that all functions part of an API version are set in the
   dispatch table.

2. Ensure that functions that cannot be part of an API version are not
   set in the dispatch table.

Commit 4bdbb58 removed the tests ability to fulfill either of its
primary goals by removing anything that used _mesa_generic_nop().  It
seems like the problem on Windows could have been resolved by adding the
NULL context pointer check from nop_handler to _mesa_generic_nop().
There is, however, some debugging benefit to actually getting the
(supposed) function name logged in the "unsupported function called"
message.

The preceding commit added a function, _glapi_new_nop_table, that
allocates a table of per-entry point no-op functions.  Restore the
ability to actually validate the sanity of the dispatch table by using
_glapi_new_nop_table.

Previous to this commit removing a function from one of the
*_functions_possible lists would not cause the test to fail.  With this
commit removing such a function will result in failure, as is expected.
