2010-11-18ktest: Added config_bisect test typeSteven Rostedt
Added the ability to do a config_bisect. It starts with a bad config and does the following loop. Enable half the configs. if none of the configs to check are not enabled (caused by missing dependencies) enable the other half. Run the test if the test passes, remove the configs from the check but enabled them for further tests (to satisfy dependencies). else Remove any config that was not enabled, as we have found a new config that can cause a failure. loop till we have only one config left.

2010-11-18ktest: Use oldnoconfig instead of yes commandSteven Rostedt
Running the command "yes ''" through the make oldconfig may enable things we do not want enabled. If something is default enabled, the yes command with '' as an argument will enable it. Use oldnoconfig, which runs everything as if 'no' was used. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2010-11-18ktest: New TEST_START instead of using [], and use real SHA1sSteven Rostedt
Change the config to use TEST_START where the options after a TEST_START automatically get the [] as it is read and they do not need to exist in the config file; TEST_START MIN_CONFIG = myconfig is the same as MIN_CONFIG[1] = myconfig The benefit is that you no longer need to keep track of test numbers with tests. Also process the commit ids that are passed to the options to get the actually SHA1 so it is no longer relative to the branch. Ie, saying HEAD will get the current SHA1 and then that will be used, and will work even if another branch is checked out. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2010-11-18ktest: Add poweroff after halt and powercycle after rebootSteven Rostedt
Added the options POWEROFF_AFTER_HALT to handle boxes that do not really shut off after a halt is called. Added POWERCYCLE_AFTER_REBOOT to force a power cycle for boxes that don't reboot but get stuck during the reboot. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2010-11-18ktest: Add open and close console and start stop monitorSteven Rostedt
It is much better to keep the monitor running throughout a test than to constantly start and stop it. Some console readers will show everything that has happened before when opening the console, and by opening it several times, causes the old content to be read multiple times in a single test.

2010-11-10perf trace: live-mode command-line cleanupTom Zanussi
This patch attempts to make the perf trace command-line for live-mode commands more user-friendly and consistent with other perf commands. The main change it makes is to allow <commands> to be run as part of perf trace live-mode commands, as other perf commands do, instead of the system-wide traces they're currently hard-coded to by the shell scripts. With this patch, the following live-mode trace now works as expected: $ perf trace rw-by-pid ls -al The previous system-wide behavior for this command would still be available by explicitly specifying -a: $ perf trace rw-by-pid -a ls -al and if no <command> is specified, the output is also system-wide: $ perf trace rw-by-pid Because live-mode requires both record and report steps to be invoked, it isn't always possible to know which args to send to the report and which to send to the record steps - mainly this is the case for report scripts with optional args - in those cases it would be necessary to use separate 'perf trace record' and 'perf trace report' steps. For example: $ perf trace syscall-counts ls Here we can't decide whether ls should be passed as a param to the syscall-counts script or whether we should invoke ls as a <command>. In these cases, we just say that we'll ignore optional script params and always interpret the extra arguments as a <command>. If the user instead wants the other interpretation, that can be accomplished by using separate record and report commands explicitly: $ perf trace record syscall-counts $ perf trace report syscall-counts ls So the rules that this patch implements, which seem to make the most intuitive sense for live-mode commands: - for commands with optional args and commands with no args, no args are sent to the report script, all are sent to the record step - for 'top' commands i.e. that end with 'top', <commands> can't be used - all extra args are send to the report script as params - for commands with required args, the n required args are taken to be the first n args after the script name and sent to the report script, and the rest are sent to the record step Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Acked-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
2010-11-10perf trace record: handle commands correctlyTom Zanussi
Because the perf-trace shell scripts hard-coded the use of the perf-record system-wide param, a perf trace record session was always system wide, even if it was given a command. If given a command, perf trace record now only records the events for the command, as users expect. If no command is given, or if the '-a' option is used, the recorded events are system-wide, as before. root@tropicana:~# perf trace record syscall-counts ls -al root@tropicana:~# perf trace ls-23152 [000] 39984.890387: sys_enter: NR 12 (0, 0, 0, 0, 0, 0) ls-23152 [000] 39984.890404: sys_enter: NR 9 (0, 0, 0, 0, 0, 0) root@tropicana:~# perf trace record syscall-counts -a ls -al root@tropicana:~# perf trace npviewer.bin-22297 [000] 39831.102709: sys_enter: NR 168 (0, 0, 0, 0, 0, 0) ls-23111 [000] 39831.107679: sys_enter: NR 59 (0, 0, 0, 0, 0, 0) Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Acked-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
2010-11-10perf record: make the record options available outside perf recordTom Zanussi

2010-11-10perf: Fix usages of profile_cpu in builtin-top.c to use cpu_listCorey Ashford
profile_cpu was left over from an earlier implementation that supported running perf top on a single CPU. profile_cpu was no longer set by any switch and usages of it resulted in dead code. Instead, convert the code to use cpu_list, which is set by the -C <cpu_list> option. Also improved the printing of nr_cpus and cpu_list by correcting the plurals.
