The existing 'offset' field is unfortunately typed as 'unsigned long',
which is unfortunately only 4 bytes with a 32-bit userspace.
Traditionally, the hardware has only supported 32-bit virtual addresses,
so even though the kernel uses a __u64, the value would always fit.
However, Broadwell supports 48-bit addressing. So with a 64-bit kernel,
the card virtual address may be too large to fit in the 'offset' field.
Ideally, we would change the type of 'offset' to be a uint64_t---but
this would break the libdrm ABI. Instead, we create a new 'offset64'
field to hold the full 64-bit value from the kernel, and store the
32-bit truncation in the existing 'offset' field, for compatibility.

I've seen a number of apps spending unreasonable amounts of time in
drm_intel_bo_busy during the buffer mapping process.
We can't track idleness in general, in the case of buffers shared
across processes. But this should significantly reduce our overhead
for checking for busy on things like VBOs.
Improves (unoptimized) glamor x11perf -f8text by 0.243334% +/-
0.161498% (n=1549), which has formerly been spending about .5% of its
time hitting the kernel for drm_intel_gem_bo_busy().

There seem to be some cases (I've noticed this switching resolution in
some games, for example) where the fd can get closed() before the device
and all it's bo's are destroyed. Which, if the drm device is opened
again and bo's are allocated with the same handles, results that when
the first pipe_screen/pipe_context is destroyed causes the first dev to
close handles for bo's allocated by the second device.
The easy solution to that is to add a mode where the fd_device creates
it's own private fd (a dup()).

Some users report hitting a divide by 0 with the tile split in
certain apps. Tile_split shouldn't ever be 0 unless the surface

cases where mesa uses an improperly initialized surface struct,

Workloads which create many transient buffers cause significant CPU
overhead in buffer allocation, zeroing, cache maint, and mmap setup.
By caching and re-using existing buffers, the CPU overhead drops
significantly. See:
http://bloggingthemonkey.blogspot.com/2013/09/freedreno-update-moar-fps.html
A simple time based policy is used for purging the cache. Once the
kernel supports it, we could use madvise style API to handle memory
pressure scenarios a bit better.

If the application sends us a file descriptor pointing at a prime
buffer that we've already got, we have to re-use the same bo_gem

Track the set of all known prime objects and look to see if the kernel
