[Mesa-dev] [PATCH 0/7] Support JSON output in aubinator

[Jordan Justen]

I was recently trying to compare the output from aubinator on two
different aub files. After manually examining the output for a while,
and, unfortunately, making little progress I thought it might be
useful to be able to programically analyze the aubinator output. JSON
seemed to be the natural choice to enable this.

I've still not solved the original issue, but I think this is still a
useful feature.

Since getting the JSON output working, I found the great 'jq' tool for
filtering JSON. Here's two quick example uses:

Print all the unique aub packet types used in the trace:

$ aubinator --gen=bdw mesa.aub --json|jq '[.[] | .Type] |unique'

Print all the unique 3DPRIMITIVE commands:

$ aubinator --gen=bdw mesa.aub --json|jq '[.[] | select(.Type | contains("PRIM"))] | unique'

Aside from this, there is also the potential to build a simple tool to
perform other more targeted analysis of aub output.
