79554aaa - tools/power/x86/intel-speed-select: Introduce TPMI interface support

Mon, 08 Aug 2022 16:01:00 +0000

tools/power/x86/intel-speed-select: Introduce TPMI interface supportTPMI (Topology Aware Register and PM Capsule Interface) creates aflexible, extendable and software-PCIe-driver-enumerable MMIO interfacefor PM features.SST feature is exposed via the TPMI interface on newer Xeon platforms.Kernel TPMI based SST driver provides a series of new IOCTLs for userspaceto use.Introduce support for the platforms that do SST control via TPMI interface.Compared with previous platforms, Newer Xeons also supports multi-punit in apackage/die, including cpu punit and non-cpu punit. These have alreadybeen handled in the generic code.Signed-off-by: Zhang Rui [srinivas.pandruvada@linux.intel.com: changelog edits]Signed-off-by: Srinivas Pandruvada List of files: /linux-6.15/tools/power/x86/intel-speed-select/Build

d0d1a603 - tools/power/x86/intel-speed-select: Introduce isst-core-mbox.c

Sat, 20 Aug 2022 10:59:54 +0000

tools/power/x86/intel-speed-select: Introduce isst-core-mbox.cisst-core.c should contain generic core APIs only.Platform specific implementations/configurations should be removed fromthis file.Introduce isst-core-mbox.c and move all mbox/mmio specific functions tothis file.Introduce struct isst_platform_ops which contains a series of callbacksthat used by the core APIs but need platform specific implementation.No functional changes are expected.Signed-off-by: Zhang Rui [srinivas.pandruvada@linux.intel.com: changelog edits]Signed-off-by: Srinivas Pandruvada List of files: /linux-6.15/tools/power/x86/intel-speed-select/Build

7d440da0 - tools/power/x86/intel-speed-select: HFI support

Wed, 19 Jan 2022 00:44:20 +0000

tools/power/x86/intel-speed-select: HFI supportRead HFI (Hardware Feedback Interface) events to process config levelchanges in oob mode. When HFI is supported there is no need for pollingto check config level change.Subscribe to Linux thermal netlink messages and process message:THERMAL_GENL_EVENT_CPU_CAPABILITY_CHANGE.This message contains cpu number, performance and energy efficiency.Signed-off-by: Srinivas Pandruvada List of files: /linux-6.15/tools/power/x86/intel-speed-select/Build

7fd786df - tools/power/x86/intel-speed-select: OOB daemon mode

Tue, 18 Jan 2022 23:02:57 +0000

tools/power/x86/intel-speed-select: OOB daemon modeIt is possible that some out of band agent changed config level. In thiscase CPUs need to be online/offline to support this config change. Adda command line option --oob, so that this tool can run as daemon and pollfor config level change and take action. The poll interval is configurablein seconds using config option --poll-interval.Signed-off-by: Srinivas Pandruvada List of files: /linux-6.15/tools/power/x86/intel-speed-select/Build

3fb4f7cd - tools/power/x86: A tool to validate Intel Speed Select commands

Sun, 30 Jun 2019 17:14:08 +0000

tools/power/x86: A tool to validate Intel Speed Select commandsThe Intel(R) Speed select technologies contains four features.Performance profile:An non architectural mechanism that allows multipleoptimized performance profiles per system via static and/or dynamicadjustment of core count, workload, Tjmax, and TDP, etc. aka ISSin the documentation.Base Frequency: Enables users to increase guaranteed base frequency oncertain cores (high priority cores) in exchange for lower base frequencyon remaining cores (low priority cores). aka PBF in the documenation.Turbo frequency: Enables the ability to set different turbo ratio limitsto cores based on priority. aka FACT in the documentation.Core power: An Interface that allows user to define per core/tilepriority.There is a multi level help for commands and options. This can be usedto check required arguments for each feature and commands for thefeature.To start navigating the features start with$sudo intel-speed-select --helpFor help on a specific feature for example$sudo intel-speed-select perf-profile --helpTo get help for a command for a feature for example$sudo intel-speed-select perf-profile get-lock-status --helpSigned-off-by: Srinivas Pandruvada Acked-by: Len Brown Acked-by: Rafael J.
