From 84c417422798c897f637b0249f64a52807b4a61b Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 5 Sep 2017 10:00:28 -0700 Subject: perf record: Support direct --user-regs arguments USER_REGS can currently only collected implicitely with call graph recording. Sometimes it is useful to see them separately, and filter them. Add a new --user-regs option to record that is similar to --intr-regs, but acts on user regs.
