Ingo Molnar 2761974156 perf bench: Default to all routines in 'perf bench mem' ... So few people know that the --routine option to 'perf bench memcpy/memset' exists, and would not know that it's capable of testing the kernel's memcpy/memset implementations. Furthermore, 'perf bench mem all' will not run all routines: vega:~> perf bench mem all # Running mem/memcpy benchmark... Routine default (Default memcpy() provided by glibc) # Copying 1MB Bytes ... 894.454383 MB/Sec 3.844734 GB/Sec (with prefault) # Running mem/memset benchmark... Routine default (Default memset() provided by glibc) # Copying 1MB Bytes ... 1.220703 GB/Sec 9.042245 GB/Sec (with prefault) Because misleadingly the 'all' refers to 'all sub-benchmarks', not 'all sub-benchmarks and routines'. Fix all this by making the memcpy/memset routine to default to 'all', which results in all the benchmarks being run: triton:~> perf bench mem all # Running mem/memcpy benchmark... Routine default (Default memcpy() provided by glibc) # Copying 1MB Bytes ... 1.448906 GB/Sec 4.957170 GB/Sec (with prefault) Routine x86-64-unrolled (unrolled memcpy() in arch/x86/lib/memcpy_64.S) # Copying 1MB Bytes ... 1.614153 GB/Sec 4.379204 GB/Sec (with prefault) Routine x86-64-movsq (movsq-based memcpy() in arch/x86/lib/memcpy_64.S) # Copying 1MB Bytes ... 1.570036 GB/Sec 4.264465 GB/Sec (with prefault) Routine x86-64-movsb (movsb-based memcpy() in arch/x86/lib/memcpy_64.S) # Copying 1MB Bytes ... 1.788576 GB/Sec 6.554111 GB/Sec (with prefault) # Running mem/memset benchmark...
