cpupower: Introduce powercap intel-rapl library and powercap-info command

2022-11-30T23:48:28+00:00

Read out powercap zone information via: cpupower powercap-info and show the zone hierarchy to the user: ./cpupower powercap-info Driver: intel-rapl Powercap domain hierarchy: Zone: package-0 (enabled) Power consumption can be monitored in micro Watts Zone: core (disabled) Power consumption can be monitored in micro Watts Zone: uncore (disabled) Power consumption can be monitored in micro Watts Zone: dram (disabled) Power consumption can be monitored in micro Watts There is a dummy -a option for powercap-info which can/should be used to show more detailed info later. Like that other args can be added easily later as well. A enable/disable option via powercap-set subcommand is also an enhancement for later. Also not all RAPL domains are shown. The func walking through RAPL subdomains is restricted and hardcoded to: "intel-rapl/intel-rapl:0" On my system above powercap domains map to: intel-rapl/intel-rapl:0 -> pack (age-0) intel-rapl/intel-rapl:0/intel-rapl:0:0 -> core intel-rapl/intel-rapl:0/intel-rapl:0:1 -> uncore Missing ones on my system are: intel-rapl-mmio/intel-rapl-mmio:0 -> pack (age-0) intel-rapl/intel-rapl:1 -> psys This could get enhanced in: struct powercap_zone *powercap_init_zones() and adopted to walk through all intel-rapl zones, but also to other powercap drivers like dtpm (Dynamic Thermal Power Management framework), cmp with: drivers/powercap/dtpm_* Signed-off-by: Thomas Renninger CC: Shuah Khan Signed-off-by: Shuah Khan

Merge tag 'acpi-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

2020-08-04T03:37:22+00:00

Pull ACPI updates from Rafael Wysocki: "These eliminate significant AML processing overhead related to using operation regions in system memory, update the ACPICA code in the kernel to upstream revision 20200717 (including a fix to prevent operation region reference counts from overflowing in some cases), remove the last bits of the (long deprecated) ACPI procfs interface and do some assorted cleanups. Specifics: - Eliminate significant AML processing overhead related to using operation regions in system memory by reworking the management of memory mappings in the ACPI code to defer unmap operations (to do them outside of the ACPICA locks, among other things) and making the memory operation reagion handler avoid releasing memory mappings created by it too early (Rafael Wysocki). - Update the ACPICA code in the kernel to upstream revision 20200717: * Prevent operation region reference counts from overflowing in some cases (Erik Kaneda). * Replace one-element array with flexible-array (Gustavo A. R. Silva). - Fix ACPI PCI hotplug reference counting (Rafael Wysocki). - Drop last bits of the ACPI procfs interface (Thomas Renninger). - Drop some redundant checks from the code parsing ACPI tables related to NUMA (Hanjun Guo). - Avoid redundant object evaluation in the ACPI device properties handling code (Heikki Krogerus). - Avoid unecessary memory overhead related to storing the signatures of the ACPI tables recognized by the kernel (Ard Biesheuvel). - Add missing newline characters when printing module parameter values in some places (Xiongfeng Wang). - Update the link to the ACPI specifications in some places (Tiezhu Yang). - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R. Silva). - Drop redundant variable initialization from the APEI code (Colin Ian King). - Drop uninitialized_var() from the ACPI PAD driver (Jason Yan). - Replace HTTP links with HTTPS ones in the ACPI code (Alexander A. Klimov)" * tag 'acpi-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (22 commits) ACPI: APEI: remove redundant assignment to variable rc ACPI: NUMA: Remove the useless 'node >= MAX_NUMNODES' check ACPI: NUMA: Remove the useless sub table pointer check ACPI: tables: Remove the duplicated checks for acpi_parse_entries_array() ACPICA: Update version to 20200717 ACPICA: Do not increment operation_region reference counts for field units ACPICA: Replace one-element array with flexible-array ACPI: Replace HTTP links with HTTPS ones ACPI: Use valid link to the ACPI specification ACPI: OSL: Clean up the removal of unused memory mappings ACPI: OSL: Use deferred unmapping in acpi_os_unmap_iomem() ACPI: OSL: Use deferred unmapping in acpi_os_unmap_generic_address() ACPICA: Preserve memory opregion mappings ACPI: OSL: Implement deferred unmapping of ACPI memory ACPI: Use fallthrough pseudo-keyword PCI: hotplug: ACPI: Fix context refcounting in acpiphp_grab_context() ACPI: tables: avoid relocations for table signature array ACPI: PAD: Eliminate usage of uninitialized_var() macro ACPI: sysfs: add newlines when printing module parameters ACPI: EC: add newline when printing 'ec_event_clearing' module parameter ...

ACPI: Use valid link to the ACPI specification

Currently, acpi.info is an invalid link to access ACPI specification, the new valid link is https://uefi.org/specifications. Signed-off-by: Tiezhu Yang Signed-off-by: Rafael J. Wysocki

cpupower: Replace HTTP links with HTTPS ones

2020-07-17T17:58:04+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Correction to manpage of cpupower

2020-01-27T15:43:31+00:00

Manpage of cpupower is listing wrong sub-commands in "See Also" section. The option for cpupower-idle(1) should actually be cpupower-idle-info(1) and cpupower-idle-set(1). This patch corrects this anomaly. Signed-off-by: Brahadambal Srinivasan Signed-off-by: Shuah Khan
