Two reasons\nfor the failure are:\n\n1. When elf section is too big (size beyond 'unsigned int' max value).\nobjdump fails to disassemble from such section. This was fixed with\ncommit 0f6329bd7fc (\"binutils/objdump: Fix disassemble for huge elf\nsections\") in binutils.\n\n2. When the sample is from hypervisor. Hypervisor symbols can not\nbe resolved within guest and thus thread__find_addr_map() fails for\nsuch symbols. Fix this by ignoring hypervisor symbols in the test.\n\nSigned-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com>\n---\nChanges in v2:\n - Add pr_debug()\n\n tools/perf/tests/code-reading.c | 5 +++++\n 1 file changed, 5 insertions(+)", "diff": "diff --git a/tools/perf/tests/code-reading.c b/tools/perf/tests/code-reading.c\nindex 761c5a4..466a462 100644\n--- a/tools/perf/tests/code-reading.c\n+++ b/tools/perf/tests/code-reading.c\n@@ -237,6 +237,11 @@ static int read_object_code(u64 addr, size_t len, u8 cpumode,\n \n \tthread__find_addr_map(thread, cpumode, MAP__FUNCTION, addr, &al);\n \tif (!al.map || !al.map->dso) {\n+\t\tif (cpumode == PERF_RECORD_MISC_HYPERVISOR) {\n+\t\t\tpr_debug(\"Hypervisor address can not be resolved - skipping\\n\");\n+\t\t\treturn 0;\n+\t\t}\n+\n \t\tpr_debug(\"thread__find_addr_map failed\\n\");\n \t\treturn -1;\n \t}\n", "prefixes": [ "v2" ] }
