Subject: [kvm-ppc-devel] [PATCH] [0/3] kvmppc: instruction emulation
Date: Mon, 14 Apr 2008 12:23:55 +0000 [thread overview]
Message-ID: <12081758382693-git-send-email-ehrhardt@linux.vnet.ibm.com> (raw)
These patch series adds two kinds of instruction emulation tracking.
A low overhead counter based mechanism extending kvm_stat (1/3) and a relayfs
based full tracing of all instructions emulated (2/3). The last patch allows
the already existant tlb tracing to be configurable (3/3) in the same manner.
All together these features help to analyze guest behavior in the virtualized
environment.
