| * tools: ffs-test: fix header values endianessMichal Nazarewicz2014-07-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * perf tools: Fix cache event name generationJiri Olsa2014-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 275ef3878f698941353780440fec6926107a320b upstream. If the event name is specified with all 3 components, the last one overwrites the previous one during the name composing within the parse_events_add_cache function. Fixing this by properly adjusting the string index.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * cpupower: Fix segfault due to incorrect getopt_long arugmentsJosh Boyer2014-01-081-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

| * perf tools: do not look at ./config for configurationJonathan Nieder2011-08-171-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit aba8d056078e47350d85b06a9cabd5afcc4b72ea upstream. In addition to /etc/perfconfig and $HOME/.perfconfig, perf looks for configuration in the file ./config, imitating git which looks at $GIT_DIR/config. If ./config is not a perf configuration file, it fails, or worse, treats it as a configuration file and changes behavior in some unexpected way. "config" is not an unusual name for a file to be lying around and perf does not have a private directory dedicated for its own use, so let's just stop looking for configuration in the cwd. Callers needing context-sensitive configuration can use the PERF_CONFIG environment variable.

| * | perf stat: Fix case where guest/host monitoring is not supported by kernelStephane Eranian2012-05-011-4/+29

But when you run perf on a kernel which does not support host/guest filtering, then you get an error saying the event in unsupported. This comes from the fact that when the perf_event_attr struct passed by the user is larger than the one known to the kernel there is safety check which ensures that all unknown bits are zero. But here, exclude_guest is 1 (part of the unknown bits) and thus the perf_event_open() syscall return EINVAL. To my surprise, running perf record on the same kernel did not exhibit the problem. The reason is that perf record handles the problem by catching the error and retrying with guest/host excludes set to zero. For some reason, this was not done with perf stat. This patch fixes this problem.

The "no_reboot" variable was only cleared if the test had reboot_on_success set. But the no_reboot variable also prevents the test rebooting when an error was detected even when REBOOT_ON_ERROR was set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When BISECT_REVERSE and BISECT_SKIP are used together with boot or test testing, build failures are treated as boot or test failures and 'git bisect bad' is executed instead of 'git bisect skip'. This is because the $ret value of -1 is treated as a build failure, but the $reverse_bisect logic does not properly handle this. Simple fix, only invert it if it is positive.
