Pavel Popov [Fri, 16 May 2014 05:00:02 +0000 (12:00 +0700)]
i965: Properly return *RESET* status in glGetGraphicsResetStatusARB

The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy.  This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context.  The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.

But ARB_robustness spec says:

  If a reset status other than NO_ERROR is returned and subsequent calls
  return NO_ERROR, the context reset was encountered and completed. If a
  reset status is repeatedly returned, the context may be in the process
  of resetting.

  8. How should the application react to a reset context event?
  RESOLVED: For this extension, the application is expected to query the
  reset status until NO_ERROR is returned. If a reset is encountered, at
  least one *RESET* status will be returned. Once NO_ERROR is
  encountered, the application can safely destroy the old context and
  create a new one.

The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned.  But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed.  For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.

The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context.  Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.

meta: Use gl_FragColor to output color values to all the draw buffers

_mesa_meta_setup_blit_shader() currently generates a fragment shader
which, irrespective of the number of draw buffers, writes the color
to only one 'out' variable. Current shader rely on an undefined
behavior and possibly works by chance.

From OpenGL 4.0  spec, page 256:
  "If a fragment shader writes to gl_FragColor, DrawBuffers specifies a
   set of draw buffers into which the single fragment color defined by
   gl_FragColor is written. If a fragment shader writes to gl_FragData,
   or a user-defined varying out variable, DrawBuffers specifies a set
   of draw buffers into which each of the multiple output colors defined
   by these variables are separately written. If a fragment shader writes
   to none of gl_FragColor, gl_FragData, nor any user defined varying out
   variables, the values of the fragment colors following shader execution
   are undefined, and may differ for each fragment color."

OpenGL 4.4 spec, page 463, added an additional line in this section:
  "If some, but not all user-defined output variables are written, the
   values of fragment colors corresponding to unwritten variables are
   similarly undefined."

V2: Write color output to gl_FragColor instead of writing to multiple
    'out' variables. This'll avoid recompiling the shader every time
    draw buffers count is updated.

now being done after IR optimization instead of before. Some quick analysis
shows that there's roughly 1.5 times more IR instructions before optimization
than after, hence the effective shader cache size got quite a bit smaller.
Could counter this with an increase of the instruction limit but it probably
makes more sense to count them after optimizations, so move that code.

Kenneth Graunke [Wed, 14 May 2014 08:07:32 +0000 (01:07 -0700)]
i965/fs: Use 'c' as the mem_ctx in fs_visitor.

Previously, the memory context situation was a bit of a mess:

fs_visitor allocated its own memory context, and freed it in the
destructor.  However, some data produced by fs_visitor (such as the list
of instructions) needs to live beyond when fs_visitor is "done", so the
caller can pass it to fs_generator.

Everything worked out because brw_wm_fs_emit's fs_visitor variables
happen to not go out of scope until the end of the function.  But that
meant that moving the declaration of, say, the SIMD16 fs_visitor
instance, could cause everything to explode.

Using a memory context that exists for the duration of the compile is
clearer, and should be equivalent.

Ultimately, we don't want to use 'c', but this matches the behavior of
fs_generator and gen8_fs_generator, so it'll be simple to change later.
