Subject: [PATCH v2 03/10] powerpc/xmon: Add PowerISA v3.1 PMU SPRs
Date: Wed, 1 Jul 2020 05:20:55 -0400 [thread overview]
Message-ID: <1593595262-1433-4-git-send-email-atrajeev@linux.vnet.ibm.com> (raw)
In-Reply-To: <1593595262-1433-1-git-send-email-atrajeev@linux.vnet.ibm.com>
From: Madhavan Srinivasan <maddy@linux.ibm.com>
PowerISA v3.1 added three new perfromance
monitoring unit (PMU) speical purpose register (SPR).
They are Monitor Mode Control Register 3 (MMCR3),
Sampled Instruction Event Register 2 (SIER2),
Sampled Instruction Event Register 3 (SIER3).
Patch here adds a new dump function dump_310_sprs
to print these SPR values.
