When we use perf kvm record-report, there is a bug in report subcommand. Example: # perf kvm stat record -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.678 MB perf.data.guest (~29641 samples) ] # perf kvm stat report failed to open perf.data: No such file or directory (try 'perf record' first) Initializing perf session failed This bug was introduced by f5fc1412. + struct perf_data_file file = { + .path = input_name, + .mode = PERF_DATA_MODE_READ, + }; kvm->tool = eops; - kvm->session = perf_session__new(kvm->file_name, O_RDONLY, 0, false, - &kvm->tool); + kvm->session = perf_session__new(&file, false, &kvm->tool); It changed the path from kvm->file_name to input_name, this patch change the path back to 'kvm->file_name', then it works well.

As there is no -v option for perf kvm, the all debug message for perf kvm will nerver be printed out to user. Example: # perf kvm --guestmount /tmp/guestmount/ record -a Not enough memory for reading perf file header It is confusing message for newbies such as me. With this patch applied, we can use -v option to get the detail.

'next_pow2()' only works for 'unsigned int' but the argument is 'unsigned long'. Checking for values less than (1 << 31) ensures that 'next_pow2()' is not passed a value out of range but lets anything else go through unvalidated. As a result mmap_pages of zero is used e.g. perf record -v -m2147483649 uname mmap size 0B failed to mmap with 22 (Invalid argument) Fixed: perf record -m2147483649 uname rounding mmap pages size to 17592186044416 bytes (4294967296 pages) Invalid argument for --mmap_pages/-m Signed-off-by:

When Jiri Olsa was writing a function callback for scsi_trace_parse_cdb(), he thought that the traceevent library had a bug in it because he was getting this error: Error: expected ')' but read ',' Error: expected ')' but read ',' Error: expected ')' but read ',' Error: expected ')' but read ',' But in truth, he didn't have the write number of arguments for the function callback, and the error was the library detecting the discrepancy. A better error message would have prevented the confusion: Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_timeout has more Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_start has more Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_error has more Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_done has more Or Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_timeout only uses 3 Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_start only uses 3 Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_error only uses 3 Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_done only uses 3 Signed-off-by:

Currently this plugin supports 2 options: 'parent' to display parent function 'indent' to show function call indents Enabling both of them by default. Signed-off-by:
