Fatal: Not all events could be opened. commit 370faf1dd046 (perf stat: Fail softly on unsupported events) added a check for failure returning ENOENT, but the POWER backend returns EOPNOTSUPP. It looks like alpha, blackfin and mips do the same.

* | ktest: Check parent options for iterated testsRabin Vincent2011-11-18
|/ | | | | | | | | | | | | | | | Let's say we have "OUTPUT_DIR = build/${TEST_NAME}", and we're iterating a test. In the second iteration of a test, the TEST_NAME of the test we're repeating is not used. Instead, ${TEST_NAME} appears literally: touch /home/rabin/kernel/test/build/${TEST_NAME}/.config ... SUCCESS Fix this by making __eval_option() check the parent test options for a repeated test.

| * ktest: Evaluate variables entered on the command lineSteven Rostedt2011-10-28
| | | | | | | | | | | | | | | | | | | | | | When ktest.pl is called without any arguments, or if the config file does not exist, ktest.pl will ask the user for some information. Some of these questions are code paths. Allowing the user to type ${PWD} for the current directory greatly simplifies these entries. Add variable processing to the entered values. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| | | | | | | | | | | | | | Adding the variable ${PWD} that equals `pwd` makes the config files much simpler. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add another monitor flush before installing kernelSteven Rostedt2011-10-22
| | | | | | | | | | | | | | | | | | | | | | | | On some tests that do multiple boots (patchcheck, bisect, etc), the build of the next kernel to run may finish before the stable kernel has finished booting. Then the install of the new kernel will fail when it tries to connect as the machine has not finished the boot process. Do one more monitor flush to make sure the machine is up and running before trying to connect to it again. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Do not opencode reboot in grub settingSteven Rostedt2011-10-20
| | | | | | | | | | | | | | | | | | | | When setting the next kernel to boot to with grub, do not opencode the reboot operation. The normal reboot operation can be modified by config options (namely POWERCYCLE_AFTER_REBOOT). This needs to affect all reboots. Remove the opencoded reboot to make sure that any changes to the reboot code also affect all reboots. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add processing of complex conditionalsSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | The IF statements for DEFAULTS and TEST_START sections now handle complex statements (&&,||) Example: TEST_START IF (DEFINED ALL_TESTS || ${MYTEST} == boottest) && ${MACHINE} == gandalf Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Fix parsing of config section linesSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | The order for some of the keywords on a section line (TEST_START or DEFAULTS) does not really matter. Simply need to remove the keyword from the line as we process it and evaluate the next keyword in the line. By removing the keywords as we find them, we do not need to keep track of where on the line they were found. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Sort make_min_config configs by dependeciesSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | The make_min_config test will turn off one config at a time and check if the config boots or not, and if it does, it will remove that config plus any config that depended on that config. ktest already looks if a config has a dependency and will try the dependency config first. But by sorting the configs and trying the config with the most configs dependent on it, we can shrink the minconfig faster. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add DEFINED keyword for IF statementsSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | Have IF statements process if a config variable or option has been defined or not. Can use NOT DEFINED in the case for telling if a variable or option has not been defined. DEFAULTS IF NOT DEFINED SSH_USER SSH_USER = root Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add OVERRIDE keyword to DEFAULTS sectionSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OVERRIDE keyword will allow options defined in the given DEFAULTS section to override options defined in previous DEFAULT sections. Normally, options will error if they were previous defined. The OVERRIDE keyword allows options that have been previously defined to be changed in the given section. Note, the same option can not be defined in the same DEFAULT section even if that section is marked as OVERRIDE. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Consolidate TEST_TYPE and DEFAULT codeSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | The code that handles parsing the TEST_TYPE and DEFAULT code share a lot of common functionality. Combine the two and add a if statement that does what is different between them. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add INCLUDE keyword to include other config filesSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | Have the reading of the config file allow reading of other config files using the INCLUDE keyword. This allows multiple config files to share config options. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Let IF keyword take comparisonsSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow ==, !=, <=, >=, <, and > to be used in IF statements to compare if a section should be processed or not. For example: BITS := 32 DEFAULTS IF ${BITS} == 32 MIN_CONFIG = ${CONFIG_DIR}/config-32 ELSE MIN_CONFIG = ${CONFIG_DIR}/config-64 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add IF and ELSE to config sectionsSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add IF keyword to sections within the config. Also added an ELSE keyword that allows different config options to be set for a given section. For example: TYPE := 1 STATUS := 0 DEFAULTS IF ${TYPE} [...] ELSE IF ${STATUS} [...] ELSE [...] The above will process the first section as $TYPE is true. If it was false, it would process the last section as $STATUS is false. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Do not reboot on config or build issuesSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | Even if REBOOT_ON_ERROR is set, it becomes annoying that the target machine is rebooted when a config option is incorrect or a build fails. There's no reason to reboot the target for host only issues. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add option REBOOT_SUCCESS_LINE to stop waiting after a rebootSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | When ktest.pl reboots, it will usuall wait SLEEP_TIME seconds of idle console before starting the next test. By setting the REBOOT_SUCCESS_LINE, ktest will not wait SLEEP_TIME when it detects the line while rebooting to a new kernel. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add NO_INSTALL option to not install for a testSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | | | | | | | There's cases where running the same kernel over and over again is useful, and being able to not install the same kernel can save time between tests. Add a NO_INSTALL option that tells ktest.pl to not install the new kernel. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Fail when grub menu not foundSteven Rostedt2011-10-17
| | | | | | | | | | | | | | | | Currently if the grub menu that is supplied is not found, it will just boot into the last grub menu in menu.lst. Fail instead of confusing the user why their kernel is not booting. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Include monitor in reboot codeAndrew Jones2011-10-17
| | | | | | | | | | | | | | | | | | | | Several places that call reboot do the same thing with respect to the monitor. By adding this code into the reboot code, redundant code is removed and it paves the way for the the reset time patch.

To achieve that the --stdio variant checks if the hist_entry being processed is the one selected by the user via the 's' hotkey. What happens now that we share the hist_entry abstractions with 'perf report' is that for minimizing locking contention multiple rb_trees are used, one for collecting the samples and other to browse/show them after resorting it by number of samples and decay them, which is done periodically. So the simple test in record_precise_ip doesn't work as we move hist_entries between those rb_trees. To fix it just check that the underlying struct symbol associated with those hist_entries is the same.

Fix it by doing just the filtering operation when collapsing because there we know that the Zoom operations adds filters just what is in hists->entries, not to the new batch of entries being collapsed. And move all the nr_entries + total_period recalculation to hists__output_resort since we will traverse all entries anyway there. Problem introduced when developing threaded addition of new batches of hist_entries, i.e. post v3.1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No need to unblock it at each ui__getch() and also allow other users to check if a resize is needed, or force an refresh of terminal dimensions. The 'force' one shouldn't be needed, but its in a slow path, so leave it like that for now, I'll revisit this another day.

So pass the xyarray with the first event, where the other events will be able to get that first per cpu fd. At some point top and record will switch to using perf_evlist__open that takes care of this detail and probably will also handle the fallback from hw to soft counters, etc. Reported-by: Deng-Cheng Zhu <dczhu@mips.com> Tested-by: Deng-Cheng Zhu <dczhu@mips.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-ebm34rh098i9y9v4cytfdp0x@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
