The latest intel-gpu-tools has dependency on cairo. We don't use cairo.
Is there any way to build intel-gpu-tools without cairo?

The last patch made PPGTT free cases correct. It left a major problem
though where in many cases it was possible to have to idle the GPU in
order to destroy a VM. This is really unfortunate as it is stalling the
active GPU process for the dying GPU process.

Some of the original PPGTT patches in this area where unmerged, and this

The comment [which was mine] is wrong. The context object can never be
bound in a PPGTT because it is only capable of living in the Global GTT.
So, remove the comment, and reorder the unref. What's nice about the
latter is it keeps the context object alive past the PPGTT. This makes

Here be all the patches to make full PPGTT relatively stable on Broadwell. Most
of the work was actually to the generic PPGTT code, and not BDW specific. There
are basically 3 fixes:
1. Make the error state not horrible, but more work still needed.
2. Fix up another tricky from != from case in do_s

The bound list is global (all objects which back the VMAs are stored

different applications using different command streamers.
With flags Would it be something like:

This may do what's required on Haswell to achieve the same as the
