Re: [Xen-devel] [PATCH 1/3] trace: allow for different sub-classes of TRC_PV_* tracepoints
On 31/05/12 12:06, David Vrabel wrote:
From: David Vrabel<david.vrabel@xxxxxxxxxx>
We want to add additional sub-classes for TRC_PV tracepoints and to be
able to only capture these new sub-classes. This cannot currently be
done as the existing tracepoints all use a sub-class of 0xf.
So, redefine the PV events to use a new sub-class. All the current
tracepoints are tracing entry points to the hypervisor so the
sub-class is named TRC_PV_ENTRY.
This change does not affect xenalyze as that only looks at the main
class and the event number and does not use the sub-class field.
