From 8521466b391f92681d64eabfeeca17de9b03585d Mon Sep 17 00:00:00 2001 From: Alistair Francis Date: Fri, 29 Aug 2014 15:00:29 +0100 Subject: [PATCH] target-arm: Implement PMCCNTR_EL0 and related registers This patch adds support for the ARMv8 version of the PMCCNTR and related registers. It also starts to implement the PMCCFILTR_EL0 register.
