  A performance monitor consists of a number of hardware and software
  counters that can be sampled by the GPU and reported back to the

I guess one could take this as a requirement that counters _must_ be sampled
by the GPU, but then why are they called _software_ counters? Besides,
there's not much reason _not_ to expose all counters that are available,

I didn't like that commit to begin with -- computing things at compile
time is fine -- but for purposes of verifying that the resulting values
are correct, looking up 0x00 and 0x30 in a table is a lot better than
evaluating a recursive function.

Anyway, by making brw_imm_vf4() take the actual 8-bit restricted floats
directly (instead of only integral values that would be converted to
restricted float), we can use this function as a replacement for the
vector float src_reg/fs_reg constructors.

brw_float_to_vf() is not currently an inline function, so it will not be
evaluated at compile time. I'll address that in a follow-up patch.

i965/nir: Add hooks for testing nir_shader_clone

This commit adds code for testing nir_shader_clone by running it after each
and every optimization pass and throwing away the old shader.  Testing
nir_shader_clone is hidden behind a new INTEL_CLONE_NIR environment
variable.

i965/nir: Validate that NIR passes call nir_metadata_preserve().

Failing to call nir_metadata_preserve() can have nasty consequences:
some pass breaks dominance information, but leaves it marked as valid,
causing some subsequent pass to go haywire and probably crash.

This pass adds a simple validation mechanism to ensure passes handle
this properly.  We add a new bogus metadata flag that isn't used for
anything in particular, set it before each pass, and ensure it *isn't*
still set after the pass.  nir_metadata_preserve will reset the flag,
so correct passes will work, and bad passes will assert fail.

(I would have made these functions static inline, but nir.h is included
in C++, so we can't bit-or enums without lots of casting...)

Thanks to Dylan Baker for the idea.

9 years agoi965/nir: Add OPT() and OPT_V() macros for invoking NIR passes.

i965/nir: Add OPT() and OPT_V() macros for invoking NIR passes.

OPT() is the normal macro for passes that return booleans, while OPT_V()
is a variant that works for passes that don't properly report progress.
(Such passes should be fixed to return a boolean, eventually.)

These macros take care of calling nir_validate_shader() and setting
progress appropriately.  In the future, it would be easy to add shader
dumping similar to INTEL_DEBUG=optimizer by extending the macro.

freedreno/a3xx: fix texture buffers, enable offsets

The main issue is that the current logic looked into cso->u.tex, which
is the wrong side of the union to look into for texture buffers. While I
was at it, it was easy enough to add the logic to handle offsets
(first_element).

 - reduce texture buffer size limit (determined experimentally)
 - don't look at first/last levels, instead look at first/last element
 - include the first element offset
 - set offset alignment to 16 (determined experimentally)
