From 6529870cb0323823f49b3e95d1760383910f96cd Mon Sep 17 00:00:00 2001 From: Madhavan Srinivasan Date: Sun, 9 Dec 2018 14:55:36 +0530 Subject: powerpc/perf: Update perf_regs structure to include MMCRA On each sample, Monitor Mode Control Register A (MMCRA) content is saved in pt_regs. MMCRA does not have a entry as-is in the pt_regs but instead, MMCRA content is saved in the "dsisr" register of pt_regs. Patch adds another entry to the perf_regs structure to include the "MMCRA" printing which internally maps to the "dsisr" of pt_regs. It also check for the MMCRA availability in the platform and present value accordingly mpe: This was the 2nd patch in a series with commit 333804dc3b7a ("powerpc/perf: Update perf_regs structure to include SIER") but I accidentally only merged the 1st patch, so merge this one now.
