perf header: Fixup reading of HEADER_NRCPUS feature

2015-10-13T02:46:09Z

commit caa470475d9b59eeff093ae650800d34612c4379 upstream. The original patch introducing this header wrote the number of CPUs available and online in one order and then swapped those values when reading, fix it. Before: # perf record usleep 1 # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 4 # nrcpus avail : 4 # echo 0 > /sys/devices/system/cpu/cpu2/online # perf record usleep 1 # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 4 # nrcpus avail : 3 # echo 0 > /sys/devices/system/cpu/cpu1/online # perf record usleep 1 # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 4 # nrcpus avail : 2 After the fix, bringing back the CPUs online: # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 2 # nrcpus avail : 4 # echo 1 > /sys/devices/system/cpu/cpu2/online # perf record usleep 1 # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 3 # nrcpus avail : 4 # echo 1 > /sys/devices/system/cpu/cpu1/online # perf record usleep 1 # perf report --header-only | grep 'nrcpus \(online\|avail\)' # nrcpus online : 4 # nrcpus avail : 4 Acked-by: Namhyung Kim Cc: Adrian Hunter Cc: Borislav Petkov Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Kan Liang Cc: Stephane Eranian Cc: Wang Nan Fixes: fbe96f29ce4b ("perf tools: Make perf.data more self-descriptive (v8)") Link: http://lkml.kernel.org/r/20150911153323.GP23511@kernel.org Signed-off-by: Arnaldo Carvalho de Melo [bwh: Backported to 3.2: print_nrcpus() reads and prints these fields immediately, so read both of them into an array before printing them in reverse order.] Signed-off-by: Ben Hutchings

tools: ffs-test: fix header values endianess

2014-08-06T17:07:33Z

commit f35f71244da6e51db4e1f2c7e318581f498ececf upstream. It appears that no one ever run ffs-test on a big-endian machine, since it used cpu-endianess for fs_count and hs_count fields which should be in little-endian format. Fix by wrapping the numbers in cpu_to_le32. Signed-off-by: Michal Nazarewicz Signed-off-by: Felipe Balbi Signed-off-by: Ben Hutchings

turbostat: Use GCC's CPUID functions to support PIC

2014-04-01T23:58:44Z

commit 2b92865e648ce04a39fda4f903784a5d01ecb0dc upstream. turbostat uses inline assembly to call cpuid. On 32-bit x86, on systems that have certain security features enabled by default that make -fPIC the default, this causes a build error: turbostat.c: In function ‘check_cpuid’: turbostat.c:1906:2: error: PIC register clobbered by ‘ebx’ in ‘asm’ asm("cpuid" : "=a" (fms), "=c" (ecx), "=d" (edx) : "a" (1) : "ebx"); ^ GCC provides a header cpuid.h, containing a __get_cpuid function that works with both PIC and non-PIC. (On PIC, it saves and restores ebx around the cpuid instruction.) Use that instead. Signed-off-by: Josh Triplett Signed-off-by: Len Brown Signed-off-by: Ben Hutchings

cpupower: Fix segfault due to incorrect getopt_long arugments

2014-02-15T19:20:14Z

commit f447ef4a56dee4b68a91460bcdfe06b5011085f2 upstream. If a user calls 'cpupower set --perf-bias 15', the process will end with a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi call. This is because the getopt_long structure currently has all of the options as having an optional_argument when they really have a required argument. We change the structure to use required_argument to match the short options and it resolves the issue.

perf tools: Add anonymous huge page recognition

2013-09-10T00:57:05Z

commit d0528b5d71faf612014dd7672e44225c915344b2 upstream. Judging anonymous memory's vm_area_struct, perf_mmap_event's filename will be set to "//anon" indicating this vma belongs to anonymous memory. Once hugepage is used, vma's vm_file points to hugetlbfs. In this way, this vma will not be regarded as anonymous memory by is_anon_memory() in perf user space utility.

perf: net_dropmonitor: Fix symbol-relative addresses

2013-05-30T13:35:05Z

commit 5a1e99dd2028e00998d42029be86835d8ef4a46e upstream. The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.
