When checking the fields in the PERF_SAMPLE_DATA_SRC type samples you need to shift the masks before doing the compare. Although the value you are checking (perf_mem_data_src) is specified as a bitfield so this might all far apart if trying to access the field in a cross-endian way. The Power people were working on this issue, not sure if they resolved it.
