Subject: [patch 0/4] Port KVM-trace to tracepoints
Date: Thu, 17 Jul 2008 11:57:24 -0400 [thread overview]
Message-ID: <20080717155724.897537670@polymtl.ca> (raw)
Hi,
Here is a port of KVM-trace, currently using macros on top of the Linux Markers,
to tracepoints. Note that I cleaned up the instrumentation too, so stuff like
KVMTRACE_3D(CR_WRITE, vcpu, (u32)cr,
(u32)kvm_register_read(vcpu, reg),
(u32)((u64)kvm_register_read(vcpu, reg) >> 32),
handler);
Sprinkled all across the KVM C code becomes :
trace_kvm_cr_write(vcpu, cr, reg);
Which looks much nicer, IMHO.
It applies on top of linux-next patch-v2.6.26-next-20080715.
Mathieu
