Subject: [PATCH 06/20] selftest/powerpc/pmu: Add macros to extract mmcr fields
Date: Thu, 27 Jan 2022 12:49:58 +0530 [thread overview]
Message-ID: <20220127072012.662451-7-kjain@linux.ibm.com> (raw)
In-Reply-To: <20220127072012.662451-1-kjain@linux.ibm.com>
From: Madhavan Srinivasan <maddy@linux.ibm.com>
Generic macro (GET_MMCR_FIELD) added to extract specific fields of
a given MMCRx. Along with it, patch also adds macro and utility
functions to fetch individual fields from
Monitor Mode Control Register 2(MMCR2) register.
