10 years agoi965: Accurately bail on SIMD16 compiles.

i965: Accurately bail on SIMD16 compiles.

Ideally, we'd like to never even attempt the SIMD16 compile if we could
know ahead of time that it won't succeed---it's purely a waste of time.
This is especially important for state-based recompiles, which happen at
draw time.

The fragment shader compiler has a number of checks like:

   if (dispatch_width == 16)
      fail("...some reason...");

This patch introduces a new no16() function which replaces the above
pattern.  In the SIMD8 compile, it sets a "SIMD16 will never work" flag.
Then, brw_wm_fs_emit can check that flag, skip the SIMD16 compile, and
issue a helpful performance warning if INTEL_DEBUG=perf is set.  (In
SIMD16 mode, no16() calls fail(), for safety's sake.)

The great part is that this is not a heuristic---if the flag is set, we
know with 100% certainty that the SIMD16 compile would fail.  (It might
fail anyway if we run out of registers, but it's always worth trying.)

i965/fs: Use a single instance of the pull_constant_loc[] array.

Now that we don't renumber uniform registers, assign_constant_locations
and move_uniform_array_access_to_pull_constants use the same names.
So, they can share a single copy of the pull_constant_loc[] array.

This simplifies the code considerably.  assign_constant_locations()
doesn't need to walk through pull_params[] to rediscover reladdr
demotions; it just has that information in pull_constant_loc[].  We also
only need to rewrite the instruction stream once, instead of twice.

Even better, we now have a single array describing the layout of
all pull parameters, which we can pass to the SIMD16 program.

This actually hurts a few shaders in Serious Sam 3, and one in KWin:
total instructions in shared programs: 1841957 -> 1842035 (0.00%)

Comparing dump_instructions() before and after the pull constant
transformations with and without this patch, it appears that there is
a uniform array with variable indexing (reladdr) and constant indexing
(of array element 0).  Previously, we uploaded array element 0 as both
a pull constant (for reladdr) /and/ a push constant.

i965/fs: Don't renumber UNIFORM registers.

Previously, remove_dead_constants() would renumber the UNIFORM registers
to be sequential starting from zero, and the resulting register number
would be used directly as an index into the params[] array.

This renumbering made it difficult to collect and save information about
pull constant locations, since setup_pull_constants() and
move_uniform_array_access_to_pull_constants() used different names.

This patch generalizes setup_pull_constants() to decide whether each
uniform register should be a pull constant, push constant, or neither
(because it's unused).  Then, it stores mappings from UNIFORM register
numbers to params[] or pull_params[] indices in the push_constant_loc
and pull_constant_loc arrays.  (We already did this for pull constants.)

Then, assign_curb_setup() just needs to consult the push_constant_loc
array to get the real index into the params[] array.

This effectively folds all the remove_dead_constants() functionality
into assign_constant_locations(), while being less irritable to work
with.

i965/fs: Split pull parameter decision making from mechanical demoting.

move_uniform_array_access_to_pull_constants() and setup_pull_constants()
both have two parts:

1. Decide which UNIFORM registers to demote to pull constants, and
   assign locations.
2. Mechanically rewrite the instruction stream to pull the uniform
   value into a temporary VGRF and use that, eliminating the UNIFORM
   file access.

In order to support pull constants in SIMD16 mode, we will need to make
decisions exactly once, but rewrite both instruction streams.
Separating these two tasks will make this easier.

This patch introduces a new helper, demote_pull_constants(), which
takes care of rewriting the instruction stream, in both cases.

For the moment, a single invocation of demote_pull_constants can't
safely handle both reladdr and non-reladdr tasks, since the two callers
still use different names for uniforms due to remove_dead_constants()
remapping of things.  So, we get an ugly boolean parameter saying
which to do.  This will go away.

i965/fs: Save push constant location information.

Previously, both move_uniform_array_access_to_pull_constants() and

information.  Storing this information will allow it to be used from
multiple functions, allowing us to split and move code around.

We'll also eventually want to pass pull constant location information
to the SIMD16 compile.  Saving this information will help us do that.

Unfortunately, the two functions *cannot* share the contents of the
array just yet.  remove_dead_constants() renumbers all the UNIFORM
registers to be contiguous starting at zero, so the two functions
talk about uniforms using different names.  We can't even remap them,
since move_uniform_array_access_to_pull_constants() deletes UNIFORM
registers that are only accessed with reladdr, so remove_dead_constants
can't even see them.
