Zechuan Chen 228a7024ed perf probe: Fix ppc64 'perf probe add events failed' case ... commit 4624f19932 upstream. Because of commit bf794bf52a ("powerpc/kprobes: Fix kallsyms lookup across powerpc ABIv1 and ABIv2"), in ppc64 ABIv1, our perf command eliminates the need to use the prefix "." at the symbol name. But when the command "perf probe -a schedule" is executed on ppc64 ABIv1, it obtains two symbol address information through /proc/kallsyms, for example: cat /proc/kallsyms | grep -w schedule c000000000657020 T .schedule c000000000d4fdb8 D schedule The symbol "D schedule" is not a function symbol, and perf will print: "p:probe/schedule _text+13958584"Failed to write event: Invalid argument Therefore, when searching symbols from map and adding probe point for them, a symbol type check is added. If the type of symbol is not a function, skip it.
