Intel GPU Tools is newer and arguably better. This change doesn't
completely merge the files because it's a bit simpler if we move the
I9XX macro over to Intel GPU Tools, and don't move over a few macros
from IGT that libdrm doesn't care about.
It has been discussed, and would seem even easier if Intel GPU Tools
simply used the libdrm header files. Whether or not we move to that,
this should help that effort.

Since there is no getparam for hardware context support, Mesa always
tries to obtain a context by calling drm_intel_gem_context_create and
NULL-checking the result. On an older kernel without context support,
this caused libdrm to print an unwanted message to stderr:

In fact, this caused every Piglit test to fail with a "warn" status due
to the unrecognized error message.

This just gets packet name and length in place, with the remainder
unfinished. I've long since finished the work that got me started
fixing up the decode.
Since CC_STATE_POINTERS for gen6 and 7 are quite different but use the
same opcode, move gen6 out to a helper function too, so we can use a
helper function for gen7.
This puts the error message in a consistent location relative to the
packet, and while I'm here I made the error message a bit more
informative.
Now, most static length packets need to just declare their length in
the table and not worry.
The overflow checks were all thoroughly untested, and a bunch of the
ones I'm deleting were pretty broken. Now, in the case of overflow,
you just decode data of 0xd0d0d0d0, and instr_out prints the warning
message instead. Note that this still has the same issue of being
under-tested, but at least it's one place instead of per-packet.
A couple of BUFFER_FAIL uses are left where the length to be decoded
could be (significantly) larger than a page, and the decode didn't
just call instr_out (which doesn't dereference data itself unless it's
safe).
The .batch was generated using the dump-a-batch branch of
git://people.freedesktop.org/~anholt/mesa
using glxgears on gen7 hardware, using INTEL_DEVID_OVERRIDE for
non-gen7 (this means that offsets in the buffers for non-gen7 are 0!).
The .ref was generated by:
./test_decode tests/gen7-3d.batch -dump.
The .sh exists because you can't supply arguments to tests using the
simple automake tests driver. Something reasonable could be done
using automake's parallel-tests driver (in fact, a previous version of
the patch did that), but I was concerned that:
1) The parallel-tests driver is documented to be unstable -- they may
change interfaces on us later.
2) The parallel-tests driver hides the output of tests in .log files
scattered all over the tree, which was ugly and more painful to
work with.

This avoids having to implement code to walk over certain sets of GL
state twice (the "compute bo list" step). While it's not a
performance improvement, it's a significant win in code complexity:
about -200 lines, and one place to make mistakes related to aperture
space instead of N places to forget some BO we should have included.
Note how if we do a reset in the new loop , we immediately flush. We
don't need to check aperture space -- the kernel will tell us if we
actually ran out of aperture or not. And if we did run out of
aperture, it's because either the single prim was too big, or because
check_aperture was wrong at the point of setting up the last

The intent of these was to catch mismatched map/unmap. What it
actually did was check whether there was ever a mapping of that type
(including in a previous life of the buffer through the userland BO
cache), not whether they were mismatched. We don't even actually want
to catch mismatched map/unmap, unless we also do refcounting, since at
one point Mesa would do map/map/use/unmap/unmap. Just remove this
code instead.
The kernel has always allowed userspace to underallocate objects
supplied for fencing. However, the kernel only allocated the object size
for the fence in the GTT and so caused tiling corruption. More recently
the kernel does allocate the full fence region in the GTT for an
under-sized object and so advertises that clients may finally make use
of this feature. The biggest benefit is for texture-heavy GL games on
i945 such as World of Padman which go from needing over 1GiB of RAM to

Urban Terror was hitting aperture size limitations. For UT, this is
because mipmap trees for power of two texture sizes will land right in
the middle between two cache buckets.
By giving a few more sizes between powers of two, Urban Terror on my

video decode on Ironlake goes from 99MB to 75MB.
cairo-perf-diff of the benchmarks for gl and xlib shows a 1.09x and

think this patch was really a no-op in terms of performance for these
CPU-bound workloads.

Bug 26686 - Some textures are distorted with libdrm 2.4.18 in GTAVC>A3
http://bugs.freedesktop.org/show_bug.cgi?id=26686
This bug continues to haunt me. The kernel SET_TILING ioctl is
inconsistent in its return values when reporting an error. If one of its
sanity checks fail, then the input values are left unchanged. If the
kernel later fails to change the tiling mode, then the input values are
modified to match the current tiling on the object. In short, userspace
cannot trust the return values upon error and so we must assume that
upon error our current tiling mode matches reality and not update.
