the libpfm4 tests are likely based on the libpfm3/perfmon2 code. Ther perfmon2 kernel patches allowed rdpmc as far as I know. If you want rdpmc in a perf_event kernel you're going to have to bug the perf_event developers on the linux-kernel list. At least one of them wasn't against the idea, but I'm sure it's a pretty low priority for them. Is what you're doing timing critical enough that having a read() syscall instead is just too much? There are issues involved with rdpmc, such as what to do if the events you've selected are multiplexing, etc. Vince ------------------------------------------------------------------------------ FREE DOWNLOAD - uberSVN with Social Coding for Subversion.
