Hi! I have in my trace instrumentation queue a series that adds a very simple
but efficient way to trigger code in QEMU from guest code using guest-agnostic
code.
Blue Swirl showed some interest long ago in using it in the test suite (e.g.,
instruct QEMU to check the vCPU state after a series of i
rget-ppc'.
* Replace all uses of 'abort()' with 'error_report_abort()' in 'target-ppc'.
Changes in v3

* Drop special object 'error_warn' in favour of raw 'error_report()'

While starting the softmmu version of QEMU, the simple backend waits for the
writeout thread to signal a condition variable when initializing the output file
path. But since the writeout thread has not been created, it just waits forever.

A separate ID space ('TRACE_CPU_*') is used in attribute 'cpu_id' that
only contains events with the 'vcpu' property.
These are later used to select the appropriate physical TB cache based
on what events are active.

The physical translation block cache is split into as many caches as wanted, and
the virtual TB cache on each guest CPU uses a (potentially) different physical
TB cache.
This is later exploited to support different tracing event states on a per-vCPU
basis.

Events with the 'tcg' and 'vcpu' properties will:
* Trace the translation-time event ('*_trans').
* Generate TCG code to call a function that traces the execution-time
event ('*_exec') iff the event is enabled for that vCPU.
