* cpupower: Fix number of idle statesThomas Renninger2012-03-031-3/+2
| | | | | | | | | | | | | | | | The number of idle states was wrong. The POLL idle state (on X86) was missed out: Number of idle states: 4 Available idle states: C1-NHM C3-NHM C6-NHM While the POLL is not a real idle state, its statistics should still be shown. It's now also explained in a detailed manpage. This should fix a bug of missing the first idle state on other archs.

* cpupower: Better interface for accessing AMD pci registersThomas Renninger2012-03-034-23/+32
| | | | | | | | | | | | | | | AMD's BKDG (Bios and Kernel Developers Guide) talks in the CPU spec of their CPU families about PCI registers defined by "device" (slot) and func(tion). Assuming that CPU specific configuration PCI devices are always on domain and bus zero a pci_slot_func_init() func which gets the slot and func of the desired PCI device passed looks like the most convenient way. This also obsoletes the PCI device id maintenance.

* perf evsel: Fix an issue where perf report fails to show the proper percentageNaveen N. Rao2012-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an issue where perf report shows nan% for certain perf.data files. The below is from a report for a do_fork probe: -nan% sshd [kernel.kallsyms] [k] do_fork -nan% packagekitd [kernel.kallsyms] [k] do_fork -nan% dbus-daemon [kernel.kallsyms] [k] do_fork -nan% bash [kernel.kallsyms] [k] do_fork A git bisect shows commit f3bda2c as the cause. However, looking back through the git history, I saw commit 640c03c which seems to have removed the required initialization for perf_sample->period. The problem only started showing after commit f3bda2c. The below patch re-introduces the initialization and it fixes the problem for me. With the below patch, for the same perf.data: 73.08% bash [kernel.kallsyms] [k] do_fork 8.97% 11-dhclient [kernel.kallsyms] [k] do_fork 6.41% sshd [kernel.kallsyms] [k] do_fork 3.85% 20-chrony [kernel.kallsyms] [k] do_fork 2.56% sendmail [kernel.kallsyms] [k] do_fork This patch applies over current linux-tip commit 9949284.

* perf tools: Fix prefix matching for kernel mapsJiri Olsa2012-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In some perf ancient versions we used '[kernel.kallsyms._text]' as the name for the kernel map. This got changed with commit: perf: 'perf kvm' tool for monitoring guest performance from host commit a1645ce12adb6c9cc9e19d7695466204e3f017fe Author: Zhang, Yanmin <yanmin_zhang@linux.intel.com> and we started to use following name '[kernel.kallsyms]_text'. This name change is important for the report code dealing with ancient perf data. When processing the kernel map event, we need to recognize the old naming (dont match the last ']') and initialize the kernel map correctly. The subsequent call to maps__set_kallsyms_ref_reloc_sym deals with the superfluous ']' to get correct symbol name.

* perf tools: Fix perf stack to non executable on x86_64Jiri Olsa2012-02-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By adding following objects: bench/mem-memcpy-x86-64-asm.o the x86_64 perf binary ended up with executable stack. The reason was that above object are assembler sourced and is missing the GNU-stack note section. In such case the linker assumes that the final binary should not be restricted at all and mark the stack as RWX. Adding section ".note.GNU-stack" definition to mentioned object, with all flags disabled, thus omiting this object from linker stack flags decision.

* perf top: Fix number of samples displayedStephane Eranian2012-01-301-3/+10
| | | | | | | | | | | | | | | | | | In recent versions of perf top, pressing the 'e' key to change the number of displayed samples had no effect. The number of samples was still dictated by the size of the terminal (stdio mode). That was quite annoying because typically only the first dozen samples really matter. This patch fixes this.

* perf tools: Fix strlen() bug in perf_event__synthesize_event_type()Stephane Eranian2012-01-301-1/+1
| | | | | | | | | | | | | | | | | | The event_type record has a max length for the event name. It's called MAX_EVENT_NAME. The name may be truncated to fit the max length. But the header.size still reflects the original name length. If that length is > MAX_EVENT_NAME, then the header.size field is bogus. Fix this by using the length of the name after the potential truncation.

* perf tools: Fix broken build by defining _GNU_SOURCE in MakefileDavid Daney2012-01-308-16/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building on my Debian/mips system, util/util.c fails to build because commit 1aed2671738785e8f5aea663a6fda91aa7ef59b5 (perf kvm: Do guest-only counting by default) indirectly includes stdio.h before the feature selection in util.h is done. This prevents _GNU_SOURCE in util.h from enabling the declaration of getline(), from now second inclusion of stdio.h, and the build is broken. There is another breakage in util/evsel.c caused by include ordering, but I didn't fully track down the commit that caused it. The root cause of all this is an inconsistent definition of _GNU_SOURCE, so I move the definition into the Makefile so that it is passed to all invocations of the compiler and used uniformly for all system header files. All other #define and #undef of _GNU_SOURCE are removed as they cause conflicts with the definition passed to the compiler. All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64 and _GNU_SOURCE) are needed by the python glue code too, so they are moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS are removed. This gives me a clean build on x86_64 (fc12) and mips (Debian).

With the SWITCH_TO_TEST which is the complement of SWITCH_TO_GOOD, which does basically the same thing as REBOOT_SCRIPT and but for both grub and script, the REBOOT_SCRIPT does not need to be mandatory anymore. Do not require the REBOOT_SCRIPT and always run the reboot code for both grub and script. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

It is even more annoying when you wake up the next day after running the test over night when you discover this. By testing if all options specified in a config file are used by either ktest or were used in one of the option's values we can see if there are any dangling options that were not used. In such a case, show the user the options that were not used and ask them if they want to continue or not. The option IGNORE_UNUSED was also added to allow the user to override this feature.

Currently, if the test returns 0, it is considered a pass (good), a non-zero is considered a fail (bad). But it has been requested to add more options, and also change the meanings of the error codes of the test. For example, one may want the test to detect if the commit is not good or bad, (maybe the bisect came to a point where the code in question does not exist). The test could report an error code that should tell ktest to skip the commit. Also, a test could detect that something is horribly wrong and the biscet should just be aborted. The new options: BISECT_RET_GOOD BISECT_RET_BAD BISECT_RET_SKIP BISECT_RET_ABORT BISECT_RET_DEFAULT have been added. The first 4 take an integer value that will represent if the test should be considered a pass, fail, neither good nor bad, or abort respectively. The BISECT_RET_DEFAULT will bo whatever is not defined by the above codes. If only BISECT_RET_DEFAULT is defined, then all tests will do the default.

A few of the questions should have a default value set, that if anything it will make it easier for the user to know what is suppose to be in that value. These new values are: SSH_USER, BUILD_TARGET and TARGET_IMAGE Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
