cpupower powercap-info
cpupower monitor -m RAPL
further development could provide:
cpupower powercap-set
to enable/disable RAPL domains, etc.

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 <trenn@suse.de> CC: Shuah Khan <skhan@linuxfoundation.org> --- tools/power/cpupower/Makefile | 14 +- tools/power/cpupower/lib/powercap.c | 290 ++++++++++++++++++ tools/power/cpupower/lib/powercap.h | 54 ++++ .../cpupower/man/cpupower-powercap-info.1 | 25 ++ tools/power/cpupower/utils/builtin.h | 2 + tools/power/cpupower/utils/cpupower.c | 1 + tools/power/cpupower/utils/powercap-info.c | 117 +++++++ 7 files changed, 499 insertions(+), 4 deletions(-) create mode 100644 tools/power/cpupower/lib/powercap.c create mode 100644 tools/power/cpupower/lib/powercap.h create mode 100644 tools/power/cpupower/man/cpupower-powercap-info.1 create mode 100644 tools/power/cpupower/utils/powercap-info.c diff --git a/tools/power/cpupower/Makefile b/tools/power/cpupower/Makefile index e9b6de314654..9fd3b309b3a6 100644 --- a/tools/power/cpupower/Makefile +++ b/tools/power/cpupower/Makefile @@ -133,7 +133,7 @@ UTIL_OBJS = utils/helpers/amd.o utils/helpers/msr.o \ utils/idle_monitor/mperf_monitor.o utils/idle_monitor/cpupower-monitor.o \ utils/cpupower.o utils/cpufreq-info.o utils/cpufreq-set.o \ utils/cpupower-set.o utils/cpupower-info.o utils/cpuidle-info.o \ - utils/cpuidle-set.o + utils/cpuidle-set.o utils/powercap-info.o UTIL_SRC := $(UTIL_OBJS:.o=.c) @@ -143,9 +143,12 @@ UTIL_HEADERS = utils/helpers/helpers.h utils/idle_monitor/cpupower-monitor.h \ utils/helpers/bitmask.h \ utils/idle_monitor/idle_monitors.h utils/idle_monitor/idle_monitors.def -LIB_HEADERS = lib/cpufreq.h lib/cpupower.h lib/cpuidle.h lib/acpi_cppc.h -LIB_SRC = lib/cpufreq.c lib/cpupower.c lib/cpuidle.c lib/acpi_cppc.c -LIB_OBJS = lib/cpufreq.o lib/cpupower.o lib/cpuidle.o lib/acpi_cppc.o +LIB_HEADERS = lib/cpufreq.h lib/cpupower.h lib/cpuidle.h lib/acpi_cppc.h \ + lib/powercap.h +LIB_SRC = lib/cpufreq.c lib/cpupower.c lib/cpuidle.c lib/acpi_cppc.c \ + lib/powercap.c +LIB_OBJS = lib/cpufreq.o lib/cpupower.o lib/cpuidle.o lib/acpi_cppc.o \ + lib/powercap.o LIB_OBJS := $(addprefix $(OUTPUT),$(LIB_OBJS)) override CFLAGS += -pipe @@ -276,6 +279,7 @@ install-lib: libcpupower $(INSTALL) -d $(DESTDIR)${includedir} $(INSTALL_DATA) lib/cpufreq.h $(DESTDIR)${includedir}/cpufreq.h $(INSTALL_DATA) lib/cpuidle.h $(DESTDIR)${includedir}/cpuidle.h + $(INSTALL_DATA) lib/powercap.h $(DESTDIR)${includedir}/powercap.h install-tools: $(OUTPUT)cpupower $(INSTALL) -d $(DESTDIR)${bindir} @@ -292,6 +296,7 @@ install-man: $(INSTALL_DATA) -D man/cpupower-set.1 $(DESTDIR)${mandir}/man1/cpupower-set.1 $(INSTALL_DATA) -D man/cpupower-info.1 $(DESTDIR)${mandir}/man1/cpupower-info.1 $(INSTALL_DATA) -D man/cpupower-monitor.1 $(DESTDIR)${mandir}/man1/cpupower-monitor.1 + $(INSTALL_DATA) -D man/cpupower-powercap-info.1 $(DESTDIR)${mandir}/man1/cpupower-powercap-info.1 install-gmo: create-gmo $(INSTALL) -d $(DESTDIR)${localedir} @@ -321,6 +326,7 @@ uninstall: - rm -f $(DESTDIR)${mandir}/man1/cpupower-set.1 - rm -f $(DESTDIR)${mandir}/man1/cpupower-info.1 - rm -f $(DESTDIR)${mandir}/man1/cpupower-monitor.1 + - rm -f $(DESTDIR)${mandir}/man1/cpupower-powercap-info.1 - for HLANG in $(LANGUAGES);

* [PATCH 2/2] cpupower: rapl monitor - shows the used power consumption in uj for each rapl domain 2022-11-23 11:18 [PATCH 0/2] Introduce powercap userspace frontend Thomas Renninger 2022-11-23 11:18 ` [PATCH 1/2] cpupower: Introduce powercap intel-rapl library and powercap-info command Thomas Renninger @ 2022-11-23 11:18 ` Thomas Renninger 1 sibling, 0 replies; 8+ messages in thread From: Thomas Renninger @ 2022-11-23 11:18 UTC (permalink / raw) To: skhan; +Cc: linux-pm, rui.zhang, daniel.lezcano, Thomas Renninger This CPU power monitor shows the power consumption as exposed by the powercap subsystem, cmp with: Documentation/power/powercap/powercap.rst cpupower monitor -m RAPL | RAPL CPU| pack | core | unco 0|6853926|967832|442381 8|6853926|967832|442381 1|6853926|967832|442381 9|6853926|967832|442381 Unfortunately RAPL domains cannot be directly mapped to the corresponding CPU socket/package, core it belongs to. Not sure this is possible at all with the current data exposed from the kernel. Still it can be worthful information for developers trying to optimize power consumption of workloads or their system in general.

Not sure this is possible at all with the current data exposed from the kernel. Still it can be worthful information for developers trying to optimize power consumption of workloads or their system in general.
