Hi, a small cleanup of vpmu structures: - struct msr_load_store_entry is unused - struct pmumsr is only used in the vmx part Dietmar.

Hi all, I want to know if PMU in Xen HVM or PV is supported now? I have done a test that in the latest xen-unstable source, "perf" command cannot give right output in VMs. My CPU is Intel(R) Xeon(R) CPU E5620 @ 2.40GHz. Thanks, Arthur -- Arthur Chunqi Li Department of Computer Science School of EECS Peking University Beijing, China _______________________________________________

...ry and kernel module for non-virtualized guests), ported to Xen, and extended to work properly in virtualized environment. Both accumulative and interrupt modes counting (profiling) are supported. The advantage of Perfctr-Xen is that it does not require specific HVM extensions which are needed for vpmu driver, can work in paravirtualized mode, and it also quite universal: works with many common tools such as PAPI, HPCToolkit, TAU PerfExplorer. It supports proper per-domain and per-thread virtualization. It is light-weight, supports wide range of CPUs, does not require save-and-restore for accumul...

Hi, When I do the "make install-tools" with xen-4.2-unstable, there are some errors about "warn_unused_result". Is it the error in code or the error in the compiling environment? Thank you so much. gcc -O1 -fno-omit-frame-pointer -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wdeclaration-after-statement -D__XEN_TOOLS__ -MMD -MF .tapdisk-queue.o.d
