* | tools/power/acpi: Add userspace AML interface supportLv Zheng2015-12-153-8/+473
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a userspace tool to access Linux kernel AML debugger interface. Tow modes are supported by this tool: 1. Interactive: Users are able to launch a debugging shell to talk with in-kernel AML debugger. Note that it's user duty to ensure kernel runtime integrity by using this debugging tool: A. Some control methods evaluated by the users may result in kernel panics if those control methods shouldn't be evaluated by the OSPMs according to the current BIOS/OS configurations. B. Currently if a single stepping evaluation couldn't run to an end, then the synchronization primitives acquired by the evaluation may block normal OSPM control method evaluations. 2. Batch: Users are able to execute debugger commands in a script. Note that in addition to the above duties, it's user duty to ensure script runtime integrity by using this debugging tool in this mode: C. Currently only those commands that are not used for single stepping are suitable to be used in this mode. D. If the execution of the command may cause a failure that could result in an endless kernel execution, the execution of the script may also get blocked. To exit the utility, currently "exit/quit" commands are recommended, but ctrl-C" can also be used. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

This reduces the dependency of Bzy_MHz calculation on the TSC. Previously, there were 4 TSC readings required in each caculation, the raw TSC delta combined with the measurement_interval. This also removes the "tsc_tweak" correction factor used when TSC runs on a different base clock from the CPU's bclk. After this change, tsc_tweak is used only for %Busy. The end-result should be a Bzy_MHz result slightly less prone to jitter. Signed-off-by: Len Brown <len.brown@intel.com>

* tools/power turbostat: SKL: Adjust for TSC difference from base frequencyLen Brown2015-09-261-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a Skylake with 1500MHz base frequency, the TSC runs at 1512MHz. This is because the TSC is no longer in the n*100 MHz BCLK domain, but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz) This adds error to several calculations in turbostat, unless the TSC sample sizes are adjusted for this difference. Note that calculations in the time domain are immune from this issue, as the timing sub-system has already calibrated the TSC against a known wall clock. AVG_MHz = APERF_delta/measurement_interval need no adjustment. APERF_delta is in the BCLK domain, and measurement_interval is in the time domain. TSC_MHz = TSC_delta/measurement_interval needs no adjustment -- as we really do want to report the actual measured TSC delta here, and measurement_interval is in the accurate time domain. %Busy = MPERF_delta/TSC_delta needs adjustment to use TSC_BCLK_DOMAIN_delta. TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval need adjustment as above. No other metrics in turbostat need to be adjusted. Before: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 24.84 2216 1512 0 2191 98.73 2219 1514 2 0 0.01 2130 1512 1 9 0.43 2016 1512 3 2 0.08 2016 1512 After: CPU Avg_MHz %Busy Bzy_MHz TSC_MHz - 550 25.05 2198 1512 0 2190 99.62 2199 1512 2 0 0.01 2152 1512 1 9 0.46 2000 1512 3 2 0.10 2000 1512 Note that in this example, the "Before" Bzy_MHz was reported as exceeding the 2200 max turbo rate. Also, even a pinned spin loop would not be reported as over 99% busy. Signed-off-by: Len Brown <len.brown@intel.com>
* tools/power turbostat: KNL workaround for %Busy and Avg_MHzHubert Chrzaniuk2015-09-261-0/+13
| | | | | | | | | | | | | | | | | | | | KNL increments APERF and MPERF every 1024 clocks. This is compliant with the architecture specification, which requires that only the ratio of APERF/MPERF need be valid. However, turbostat takes advantage of the fact that these two MSRs increment every un-halted clock at the actual and base frequency: AVG_MHz = APERF_delta/measurement_interval %Busy = MPERF_delta/TSC_delta This quirk is needed for these calculations to also work on KNL, which would otherwise show a value 1024x smaller than expected.

On the cpufreq front, there are many cleanups and minor fixes in the core and governors, driver updates etc. We also have a new cpufreq driver for Mediatek MT8173 chips. ACPICA mostly updates its debug infrastructure and adds a number of fixes and cleanups for a good measure. The Operating Performance Points (OPP) framework is updated with new DT bindings and support for them among other things. We have a few updates of the generic power domains framework and a reorganization of the ACPI device enumeration code and bus type operations. And a lot of fixes and cleanups all over. Included is one branch from the MFD tree as it contains some PM-related driver core and ACPI PM changes a few other commits are based on.

The cpufreq core fixes from Viresh Kumar are quite significant too as far as the number of commits goes and because they should reduce CPU online/offline overhead quite a bit in the majority of cases. From the new featues point of view, the ACPICA update (to upstream revision 20150515) adding support for new ACPI 6 material to ACPICA is the one that matters the most as some new significant features will be based on it going forward. Also included is an update of the ACPI device power management core to follow ACPI 6 (which in turn reflects the Windows' device PM implementation), a PM core extension to support wakeup interrupts in a more generic way and support for the ACPI _CCA device configuration object. The rest is mostly fixes and cleanups all over and some documentation updates, including new DT bindings for Operating Performance Points. There is one fix for a regression introduced in the 4.1 cycle, but it adds quite a number of lines of code, it wasn't really ready before Thursday and you were on vacation, so I refrained from pushing it on the last minute for 4.1. Specifics: - ACPICA update to upstream revision 20150515 including basic support for ACPI 6 features: new ACPI tables introduced by ACPI 6 (STAO, XENV, WPBT, NFIT, IORT), changes related to the other tables (DTRM, FADT, LPIT, MADT), new predefined names (_BTH, _CR3, _DSD, _LPI, _MTL, _PRR, _RDI, _RST, _TFP, _TSN), fixes and cleanups (Bob Moore, Lv Zheng). - ACPI device power management core code update to follow ACPI 6 which reflects the ACPI device power management implementation in Windows (Rafael J Wysocki). - rework of the backlight interface selection logic to reduce the number of kernel command line options and improve the handling of DMI quirks that may be involved in that and to make the code generally more straightforward (Hans de Goede). - fixes for the ACPI Embedded Controller (EC) driver related to the handling of EC transactions (Lv Zheng). - fix for a regression related to the ACPI resources management and resulting from a recent change of ACPI initialization code ordering (Rafael J Wysocki). - fix for a system initialization regression related to ACPI introduced during the 3.14 cycle and caused by running the code that switches the platform over to the ACPI mode too early in the initialization sequence (Rafael J Wysocki). - support for the ACPI _CCA device configuration object related to DMA cache coherence (Suravee Suthikulpanit). - ACPI/APEI fixes and cleanups (Jiri Kosina, Borislav Petkov). - ACPI battery driver cleanups (Luis Henriques, Mathias Krause). - ACPI processor driver cleanups (Hanjun Guo). - cleanups and documentation update related to the ACPI device properties interface based on _DSD (Rafael J Wysocki). - ACPI device power management fixes (Rafael J Wysocki). -
