[PATCH] perf script: Fix printing 'phys_addr' failure issue
Posted by Wei Li 4 years, 5 months ago 
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
  4064384/4064384 ffff802f921be0d0      2f921be0d0

Hi Wei,

This looks good to me. As a followup we could also fix the 'weight'
field, which was introduced recently.

Also it looks like the SPE samples are also missing the PHYS_ADDR flag.
I think we'll need to fix the consistency of the flags.

Many thanks,
German
