Subject: [PATCH 0/3] perf: arm-spe: Fix addresses of synthesized Arm SPE events
Date: Thu, 21 Apr 2022 17:52:02 +0100 [thread overview]
Message-ID: <20220421165205.117662-1-timothy.hayes@arm.com> (raw)
This patch set fixes problems related to address in synthesized events from SPE.
Committer testing:
perf record --no-bpf-event -e arm_spe_0/pa_enable=1/ -- sleep 1
perf inject -i perf.data -o perf-inj.data --itrace --strip
perf script -i perf-inj.data --fields hw:+addr,+phys_addr
Before:
sleep 49337 [004] 20133.731889: 1 l1d-access: ffffcbebcde1d5b8 [unknown] ([unknown])
sleep 49337 [004] 20133.731889: 1 tlb-access: ffffcbebcde1d5b8 [unknown] ([unknown])
