From mboxrd@z Thu Jan 1 00:00:00 1970 From: ehrhardt@linux.vnet.ibm.com Date: Mon, 14 Apr 2008 12:23:55 +0000 Subject: [kvm-ppc-devel] [PATCH] [0/3] kvmppc: instruction emulation Message-Id: <12081758382693-git-send-email-ehrhardt@linux.vnet.ibm.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: kvm-ppc@vger.kernel.org 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. arch/powerpc/kvm/Kconfig | 17 +++++++ arch/powerpc/kvm/emulate.c | 84 +++++++++++++++++++++++++++++++++++++++ arch/powerpc/kvm/powerpc.c | 15 ++++++ b/arch/powerpc/kvm/44x_tlb.c | 2 b/arch/powerpc/kvm/Kconfig | 8 +++ b/arch/powerpc/kvm/emulate.c | 61 ++++++++++++++++++++++++++++ b/arch/powerpc/kvm/powerpc.c | 84 +++++++++++++++++++++++++++++++++++++++ b/include/asm-powerpc/kvm_host.h | 40 ++++++++++++++++++ b/include/asm-powerpc/kvm_ppc.h | 50 +++++++++++++++++++++++ 9 files changed, 360 insertions(+), 1 deletion(-) ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
