Run with:
  GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.

If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
  /home/$username/dd_dumps/$processname_$pid_$index.

Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.

You can also do:
  GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.

Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.

8 years agonir: Pass a type_size() function pointer into nir_lower_io().

nir: Pass a type_size() function pointer into nir_lower_io().

Previously, there were four type_size() functions in play - the i965
compiler backend defined scalar and vec4 type_size() functions, and
nir_lower_io contained its own similar functions.

In fact, the i965 driver used nir_lower_io() and then looped over the
components using its own type_size - meaning both were in play.  The
two are /basically/ the same, but not exactly in obscure cases like
subroutines and images.

This patch removes nir_lower_io's functions, and instead makes the
driver supply a function pointer.  This gives the driver ultimate
flexibility in deciding how it wants to count things, reduces code
duplication, and improves consistency.

v2 (Jason Ekstrand):
 - One side-effect of passing in a function pointer is that nir_lower_io is
   now aware of and properly allocates space for image uniforms, allowing
