Hi,
For those who would like to try that patch and are not familiar with
trace points, here are some very basic instructions to start with.
- in your qemu configure command line, add
--enable-trace-backends=stderr
This enables the stderr trace backend.
- create a events.txt file where you launch qemu
add the trace points you want to observe.
list of trace points can be found in trace-events (qemu root dir).
In the VFIO device, they are trace_<event>
for instance add:
vfio_intx_interrupt
vfio_eoi
wildcard seems to work as well. lines can be commented with #
- when launching qemu, add
-trace events=events.txt
Complete details can be found in docs/tracing.txt
Best Regards
Eric
