https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #25 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> --- IIRC this was working fine last time I've tried. Have you loaded the pmc mo= dule (kldload pmc), and which CPU are you using? Note that you also need to enab= le the PMU support in Xen [0] by passing vpmu=3D1 on the Xen command line. PMC.HASWELL(3) lists RESOURCE_STALLS.ANY as a valid event. If that doesn't = work (or is too complicated to setup) I would try with dtrace, and let's see wha= t we get.
