This will essentially enable modifiers from clients that were just

setting all of them at create, but had no way to actually query them
after creating the surface (ie. stupid clients could be broken before

Obviously, there are no modifiers being actually stored yet - so this

i965: Shut up major()/minor() warnings.

Recent glibc generates this warning:

brw_performance_query.c:1648:13: warning: In the GNU C Library, "minor" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "minor", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "minor", you should undefine it after including <sys/types.h>.

    min = minor(sb.st_rdev);

So, include sys/sysmacros.h to shut up the warning.

v2: Use the AC_HEADER_MAJOR defines to figure out the right header
    (thanks to Jonathan Gray for helping me not break non-glibc systems)

i965: Drop AUB_TRACE_* stuff.

This was used for aubdumping (deleted a while ago) and INTEL_DEBUG=bat
decoding (deleted recently).

While we're changing parameters, delete the wrapper macro and make the
actual function brw_state_batch instead of __brw_state_batch.

This subsumes a patch by Emil Velikov to drop this from BLORP.

i965: Use aubinator/genxml for INTEL_DEBUG=bat state decoding.

This deletes all of our handwritten code in favor of autogenerated
genxml-based decoding.  This should be much more usable, as the old
code isn't entirely accurate - we updated some things for new
generations, but not everything.

Aubinator has one annoying limitation: it has no idea how many entries
to print when encountering e.g. 3DSTATE_BINDING_TABLE_POINTERS_VS.  It
picks an arbitrary number, which may skip decoding valid data, and may
print extra garbage entries.

We do a better job here by making brw_state_batch track the size of the
data stored at a particular batchbuffer offset.  Then, we can divide by
the structure size to obtain the exact number of entries.

i965: Use aubinator/genxml for INTEL_DEBUG=bat commands.

This should give substantially better decoding, as the public libdrm
decoder hasn't been properly maintained in years.

For now, we reuse the existing state dumping mechanism.  We'll improve
that in the next patch.

To avoid increasing the size of the driver, we restrict this feature
to debug builds of Mesa.  There's probably very little use for it in
release builds anyway.

i965: Skip register write detection when possible.

Detecting register write support by trial and error introduces a
stall at screen creation time, which it would be nice to avoid.
Certain command parser versions guarantee this will work (see the
giant comment in intelInitScreen2 below, or a few commits ago):

- Ivybridge: version >= 1 (kernel v3.16)
- Baytrail:  version >= 2 (kernel v3.19)
- Haswell:   version >= 7 (kernel v4.8)

For simplicity, we don't bother with version 1 in this patch.

This assumes that the user hasn't disabled aliasing PPGTT via a kernel
command line parameter.  Don't do that - you're only breaking things.

If we can't write registers, then the effective command parser version

i965: Fall back to GL 4.2/4.3 on Haswell if the kernel isn't new enough.

In commit d2590eb65ff28a9cbd592353d15d7e6cbd2c6fc6 I enabled GL 4.5
on Haswell...but failed to check if we could do indirect compute
shader dispatch...and query buffer objects.

Indirect compute shader dispatch requires command parser version 5
(kernel commit 7b9748cb513a6bef4af87b79f0da3ff7e8b56cd8, which is in
Linux v4.4).  On earlier kernels we would have disabled
ARB_compute_shader, which is a mandatory part of OpenGL 4.3+.

Query buffer objects currently require MI_MATH and MI_LOAD_REGISTER_REG,
which mean command parser version 7 (Linux v4.8).  On earlier kernels
we would have disabled ARB_query_buffer_object, which is a mandatory
part of OpenGL 4.4+.

The new version support looks like:

- Kernel 4.1 and older => OpenGL 3.3
- Kernel 4.2-4.3       => OpenGL 4.2
- Kernel 4.4-4.7       => OpenGL 4.3
- Kernel 4.8+          => OpenGL 4.5
