Subject: [PATCH] perf script: Fix printing 'phys_addr' failure issue
Date: Fri, 21 Jan 2022 14:59:54 +0800 [thread overview]
Message-ID: <20220121065954.2121900-1-liwei391@huawei.com> (raw)
From: Yao Jin <jinyao5@huawei.com>
Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.
Now referring to 'addr', use evsel__do_check_stype() to check the type.
Before:
# perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr
Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.
After:
# perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr
4064384/4064384 ffff802f921be0d0 2f921be0d0
