Cota" , Stefan Hajnoczi This series adds an API to add instrumentation events. It also provides additional APIs for: * Controlling tracing events * Peek/poke guest memory There's still missing APIs for (can be added in later series?): * Provide something like tracing's per-vCPU trace states (i.e., so that e= ach vCPU can have different instrumentation code). It's still not clear to = me if we should extend the per-vCPU bitmap with instrumentation events, or ot= herwise somehow reuse the bits in tracing events (since they're currently limit= ed). * Peek/poke guest registers The instrumentation code is dynamically loaded as a library into QEMU eit= her when it starts or later using its remote control interfaces. Signed-off-by: Llu=C3=ADs Vilanova --- Changes in v4 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D * Add missing stub function. Changes in v3 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D * Use a separate event set for instrumentation (i.e., do not instrument t= racing events) [Stefan Hajnoczi]. * Add API for peek/poke guest memory. Changes in v2 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D * Update QEMU version in QAPI [Eric Blake]. * Clarify 'msg' result in QAPI is for humans only. * Make 'msg' and 'handle' results optional in QAPI. * Use a list of 'str' in 'instr-load' QAPI command. * Update MAINTAINERS. * Add macros for error-reporting in API.
