Thanks for the review - now await v3 as I can see my CI died on a whole
bunch of non-TCG builds!

Sorry about the mess up I introduced in refactoring, and thanks for
fixing it for me.

[PATCH v2] monitor: move x-query-profile into accel/tcg to fix build

2021-12-14 Thread Alex Bennée
As --enable-profiler isn't defended in CI we missed this breakage.
Move the qmp handler into accel/tcg so we have access to the helpers
we need. While we are at it ensure we gate the feature on CONFIG_TCG.
