From 330a1eb7775ba876dbd46b9885556e57f705e3d4 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 28 Jun 2013 18:15:16 +1000 Subject: powerpc/perf: Core EBB support for 64-bit book3s Add support for EBB (Event Based Branches) on 64-bit book3s. See the included documentation for more details. EBBs are a feature which allows the hardware to branch directly to a specified user space address when a PMU event overflows. This can be used by programs for self-monitoring with no kernel involvement in the inner loop. Most of the logic is in the generic book3s code, primarily to avoid a proliferation of PMU callbacks.
