[Mesa-dev] [PATCH 4/4] intel/aubinator: Pull useful information from the AUB header

[Jason Ekstrand]

This commit does two things.  One is to pull useful and/or interesting
information from the AUB file header and display it as a header above your
decoded batches.  Second, it is now capable of pulling the PCI ID from the
AUB file comment left by intel_aubdump.  This removes the need to use the
--gen flag all the time.
