2017-02-25tools/power turbostat: Add --show and --hide parametersLen Brown2-120/+347
Add the "--show" and "--hide" cmdline parameters. By default, turbostat shows all columns. turbostat --hide counter_list will continue showing all columns, except for those listed. turbostat --show counter_list will show _only_ the listed columns These features work for built-in counters, and have no effect on columns added with the --add parameter. Signed-off-by: Len Brown <len.brown@intel.com>
2017-02-25tools/power turbostat: fix bugs in --add optionLen Brown1-36/+52
When --add was used more than once, overflowed buffers caused some counters to be stored on top of others, corrupting the results. Simplify the code by simply reserving space for up to 16 added counters per each cpu, core, package. Per-cpu added counters were being printed only per-core.

2017-02-16tools/power/x86: Debug utility for intel_pstate driverDoug Smythies1-0/+569
This utility can be used to debug and tune the performance of the intel_pstate driver. This utility can be used in two ways: - If there is Linux trace file with pstate_sample events enabled, then this utility can parse the trace file and generate performance plots. - If user has not specified a trace file as input via command line parameters, then this utility enables and collects trace data for a user-specified interval and generates performance plots.

2016-12-01tools/power turbostat: Gracefully handle ACPI S3Len Brown1-42/+35
turbostat gives valid results across suspend to idle, aka freeze, whether invoked in interval mode, or in command mode. Indeed, this can be used to measure suspend to idle: turbostat echo freeze > /sys/power/state But this does not work across suspend to ACPI S3, because the processor counters, including the TSC, are reset on resume. Further, when turbostat detects a problem, it does't forgive the hardware, and interval mode will print *'s from there on out. Instead, upon detecting counters going backwards, simply reset and start over. Interval mode across ACPI S3: (observe TSC going backwards) root@sharkbay:/home/lenb/turbostat-src# ./turbostat -M 0x10 CPU Avg_MHz Busy% Bzy_MHz TSC_MHz MSR 0x010 - 1 0.06 858 2294 0x0000000000000000 0 0 0.06 847 2294 0x0000002a254b98ac 1 1 0.06 878 2294 0x0000002a254efa3a 2 1 0.07 843 2294 0x0000002a2551df65 3 0 0.05 863 2294 0x0000002a2553fea2 turbostat: re-initialized with num_cpus 4 CPU Avg_MHz Busy% Bzy_MHz TSC_MHz MSR 0x010 - 2 0.20 849 2294 0x0000000000000000 0 2 0.26 856 2294 0x0000000449abb60d 1 2 0.20 844 2294 0x0000000449b087ec 2 2 0.21 850 2294 0x0000000449b35d5d 3 1 0.12 839 2294 0x0000000449b5fd5a ^C Command mode across ACPI S3: root@sharkbay:/home/lenb/turbostat-src# ./turbostat -M 0x10 sleep 10 ./turbostat: Counter reset detected 14.196299 sec Signed-off-by: Len Brown <len.brown@intel.com>
2016-12-01tools/power turbostat: tidy up output on Joule counter overflowLen Brown1-5/+1
The RAPL Joules counter is limited in capacity. Turbostat estimates how soon it can roll-over based on the max TDP of the processor -- which tells us the maximum increment rate. eg. RAPL: 2759 sec. Joule Counter Range, at 95 Watts So if a sample duration is longer than 2759 seconds on this system, '**' replace the decimal place in the display to indicate that the results may be suspect. But the display had an extra ' ' in this case, throwing off the columns. Also, the -J "Joules" option appended an extra "time" column to the display. While this may be useful, it printed the interval time, which may not be the accurate time per processor. Remove this column, which appeared only when using '-J', as we plan to add accurate per-cpu interval times in a future commit. Signed-off-by: Len Brown <len.brown@intel.com>

2016-08-13ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issueLv Zheng3-2/+1
ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09 When /Za is specified, headers of some Windows SDKs contain bugs breaking VC builds, and MSVC9's default SDK is one of such header-buggy library. In order to solve this issue, many VC developers stop using /Za. However we've been asked to have this fixed without removing /Za. In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h> to be the last standard file included by every source file in the projects. This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this issue can be fixed by ensuring that "acapps.h" is always the last standard file included by all of the ACPICA source files. This is in fact also a useful cleanup because applications can only include one header (e.x., acpidump.h) instead of including acapps.h separately. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.

2016-08-13ACPICA: Clib/EFI: Fix wrong order of standard integer types/IO handlesLv Zheng2-6/+0
ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d EFI header should use standard C library stuffs (integer types and IO handles) rather than implementing such standard stuffs. This patch fixes this issue by: 1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n; 2. Defining EFI types using standard integer types and standard IO handles; 3. Tuning header inclusion order and environment definition order; 4. Removing wrong standard header inclusion from ACPICA core files; 5. Moving several application headers from acpidump.h to acenv.h. This patch corrects some of them. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.

2016-08-13ACPICA: Clib: Fix build issues when ACPI_USE_STANDARD_HEADERS is not defined by converting size_t to acpi_sizeLv Zheng1-2/+2
ACPICA commit 7cf411136c69ef0b8f184b96599eb45c15b89226 When standard size_t is not defined due to ACPI_USE_STANDARD_HEADERS=n, we shouldn't use size_t, but should use acpi_size instead.

2016-08-13ACPICA: OSL: Add correct acpi_gbl_debug_timeout export to allow acpiexec to linkLv Zheng1-3/+0
ACPICA commit 408198c8c9786f9f104ee925020c3ab1701906e4 The acpi_gbl_debug_timeout which is used by acpiexec -et option now is only implemented in oswinxf.c and used for WIN32 builds. This makes it very difficult to remember that we need to add this variable to other os specific layer files in order for linking. This patch makes it a global option dependent on ACPI_APPLICATION so that it can always be linked by the applications. Lv Zheng.

Pull ACPI updates from Rafael Wysocki: "The new feaures here are the support for ACPI overlays (allowing ACPI tables to be loaded at any time from EFI variables or via configfs) and the LPI (Low-Power Idle) support. Also notable is the ACPI-based NUMA support for ARM64. Apart from that we have two new drivers, for the DPTF (Dynamic Power and Thermal Framework) power participant device and for the Intel Broxton WhiskeyCove PMIC, some more PMIC-related changes, support for the Boot Error Record Table (BERT) in APEI and support for platform-initiated graceful shutdown. Plus two new pieces of documentation and usual assorted fixes and cleanups in quite a few places.
