Subject: [PATCH V3 05/10] perf: Add PERF_BR_NEW_ARCH_[N] map for BRBE on arm64 platform
Date: Mon, 14 Mar 2022 11:28:52 +0530	[thread overview]
Message-ID: <20220314055857.125421-6-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20220314055857.125421-1-anshuman.khandual@arm.com>

BRBE captured branch types will overflow perf_branch_entry.type and generic
branch types in perf_branch_entry.new_type. So override each available arch
specific branch type in the following manner to comprehensively process all
reported branch types in BRBE.

PERF_BR_NEW_FIQ            PERF_BR_NEW_ARCH_1
PERF_BR_NEW_DEBUG_HALT     PERF_BR_NEW_ARCH_2
PERF_BR_NEW_DEBUG_EXIT     PERF_BR_NEW_ARCH_3
PERF_BR_NEW_DEBUG_INST     PERF_BR_NEW_ARCH_4
PERF_BR_NEW_DEBUG_DATA     PERF_BR_NEW_ARCH_5
