During execution of command 'perf report' in my arm64 virtual machine,
this error message is showed:
failed to process sample
__symbol__inc_addr_samples(860): ENOMEM! sym->name=__this_module,
start=0x1477100, addr=0x147dbd8, end=0x80002000, func: 0
The error is caused with path:
cmd_report
__cmd_report

__perf_session__process_events
ordered_events__flush
__ordered_events__flush
oe->deliver (ordered_events__deliver_event)

iter->add_entry_cb(hist_iter__report_callback)
hist_entry__inc_addr_samples
symbol__inc_addr_samples
__symbol__inc_addr_samples
h = annotated_source__histogram(src, evidx) (NULL)
annotated_source__histogram failed is caused with path:
...
hist_entry__inc_addr_samples
symbol__inc_addr_samples
symbol__hists
annotated_source__alloc_histograms
src->histograms = calloc(nr_hists, sizeof_sym_hist) (failed)
Calloc failed as the symbol__size(sym) is too huge. As show in error
message: start=0x1477100, end=0x80002000, size of symbol is about 2G.
