QEMU Tooling ([VIRT-252])
=========================
- thoughts after reviewing {Qemu-devel} {RFC PATCH v2 0/7} QEMU binary
instrumentation prototype Message-Id:
<152819515565.30857.16834004920507717324.stgit@pasha-ThinkPad-T60>
- we want rich tooling but don't want to leak internals to plugins
- the proposed helper per insn is pretty limited/hacky
- I think we could expand exiting trace support with plugins
- plugin hook to trace points
- plugin either filters trace points or does in-situ analysis
- existing trace infrastructure used to export data
