2024-07-02cpupower: fix lib default installation pathRoman Storozhenko1-9/+1
Invocation the tool built with the default settings fails: $ cpupower cpupower: error while loading shared libraries: libcpupower.so.1: cannot open shared object file: No such file or directory The issue is that Makefile puts the library to "/usr/lib64" dir for a 64 bit machine. This is wrong. According to the "File hierarchy standard specification: https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.pdf "/usr/lib<qual>" dirs are intended for alternative-format libraries (e.g., "/usr/lib32" for 32-bit libraries on a 64-bit machine (optional)). The utility is built for the current machine and doesn't handle 'CROSS_COMPILE' and 'ARCH' env variables. It also doesn't change bit depth. So the result is always the same - binary for x86_64 architecture. Therefore the library should be put in the '/usr/lib' dir regardless of the build options. This is the case for all the distros that comply with the 'File Hierarchy Standard 3.0" by Linux Foundation. Most of the distros comply with it. For example, one can check this by examining the "/usr/lb64" dir on debian-based distros and find that it contains only "/usr/lib64/ld-linux-x86-64.so.2". And examine that "/usr/lib" contains both 32 and 64 bit code: find /usr/lib -name "*.so*" -type f | xargs file | grep 32-bit find /usr/lib -name "*.so*" -type f | xargs file | grep 64-bit Fix the issue by changing library destination dir to "/usr/lib".

2024-06-27tools/power turbostat: Fix unc freq columns not showing with '-q' or '-l'Adam Hawley1-8/+8
Commit 78464d7681f7 ("tools/power turbostat: Add columns for clustered uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()' in a way which prevents printing uncore frequency columns if either of the '-q' or '-l' options are used. Systems which do not have multiple uncore frequencies per package are unaffected by this regression. Fix the function so that uncore frequency columns are shown when either the '-l' or '-q' option is used by checking if 'quiet' is true after adding counters for the uncore frequency columns.

2024-06-27tools/power turbostat: option '-n' is ambiguousDavid Arcari1-1/+1
In some cases specifying the '-n' command line argument will cause turbostat to fail. For instance 'turbostat -n 1' works fine; however, 'turbostat -n 1 -d' will fail. This is the result of the first call to getopt_long_only() where "MP" is specified as the optstring. This can be easily fixed by changing the optstring from "MP" to "MPn:" to remove ambiguity between the arguments. tools/power turbostat: option '-n' is ambiguous; possibilities: '-num_iterations' '-no-msr' '-no-perf' Fixes: a0e86c90b83c ("tools/power turbostat: Add --no-perf option") Signed-off-by: David Arcari <darcari@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>

2024-05-01tools/power turbostat: Enable non-privileged users to read sysfs countersPatryk Wlazlyn1-25/+31
A group of counters called "sysfs" displays software C-state request counts and resulting perceived C-state residency. They are not built-in counters that turbostat knows about ahead of time, rather they are discovered in sysfs when turbostat starts. Thus, they are added dynamically, using the same interface as user-added MSR counters. When turbostat enters "no-msr" mode, such as when running as a non-privileged user, it clears all added counters. Updating that to clear only actual MSR added counters allows regular users to see the sysfs counters.

Add a turbostat "snapshot" makefile target to create a standalone source snapshot from the developer's git tree, appropriately hacked so that the customer can build turbostat without a kernel tree. Include the turbostat binary in the snapshot, for convenience in those situations where the source and destination are trusted, (and have new enough glibc to execute). The snapshot is named with the date it was taken rather than the turbostat VERSION, as it could occur between VERSIONS... Signed-off-by: Len Brown <len.brown@intel.com>

2024-04-10tools/power turbostat: v2024.04.10Len Brown1-15/+26
Much of turbostat can now run with perf, rather than using the MSR driver Some of turbostat can now run as a regular non-root user. Add some new output columns for some new GFX hardware. [This patch updates the version, but otherwise changes no function; it touches up some checkpatch issues from previous patches] Signed-off-by: Len Brown <len.brown@intel.com>
2024-04-10tools/power/turbostat: Add support for Xe sysfs knobsZhang Rui1-0/+51
Xe graphics driver uses different graphics sysfs knobs including /sys/class/drm/card0/device/tile0/gt0/gtidle/idle_residency_ms /sys/class/drm/card0/device/tile0/gt0/freq0/cur_freq /sys/class/drm/card0/device/tile0/gt0/freq0/act_freq /sys/class/drm/card0/device/tile0/gt1/gtidle/idle_residency_ms /sys/class/drm/card0/device/tile0/gt1/freq0/cur_freq /sys/class/drm/card0/device/tile0/gt1/freq0/act_freq Plus that, /sys/class/drm/card0/device/tile0/gt<n>/gtidle/name returns either gt<n>-rc or gt<n>-mc. rc is for GFX and mc is SA Media. Enhance turbostat to prefer the Xe sysfs knobs when they are available. Export gt<n>-rc via BIC_GFX_rc6/BIC_GFXMHz/BIC_GFXACTMHz. Export gt<n>-mc via BIC_SMA_mc6/BIC_SMAMHz/BIC_SMAACTMHz.

2024-04-10tools/power/turbostat: Add support for new i915 sysfs knobsZhang Rui1-0/+24
On Meteorlake platform, i915 driver supports the traditional graphics sysfs knobs including /sys/class/drm/card0/power/rc6_residency_ms /sys/class/drm/card0/gt_cur_freq_mhz /sys/class/drm/card0/gt_act_freq_mhz At the same time, it also supports /sys/class/drm/card0/gt/gt0/rc6_residency_ms /sys/class/drm/card0/gt/gt0/rps_cur_freq_mhz /sys/class/drm/card0/gt/gt0/rps_act_freq_mhz /sys/class/drm/card0/gt/gt1/rc6_residency_ms /sys/class/drm/card0/gt/gt1/rps_cur_freq_mhz /sys/class/drm/card0/gt/gt1/rps_act_freq_mhz gt0 is for GFX and gt1 is for SA Media. Enhance turbostat to prefer the i915 new sysfs knobs. Export gt0 via BIC_GFX_rc6/BIC_GFXMHz/BIC_GFXACTMHz. Export gt1 via BIC_SMA_mc6/BIC_SMAMHz/BIC_SMAACTMHz.

2024-04-10tools/power/turbostat: Introduce BIC_SAM_mc6/BIC_SAMMHz/BIC_SAMACTMHzZhang Rui2-7/+96
Graphics driver (i915/Xe) on mordern platforms splits GFX and SA Media information via different sysfs knobs. Existing BIC_GFX_rc6/BIC_GFXMHz/BIC_GFXACTMHz columns can be reused for GFX. Introduce BIC_SAM_mc6/BIC_SAMMHz/BIC_SAMACTMHz columns for SA Media. Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2024-04-09tools/power/turbostat: Fix uncore frequency file stringJustin Ernst1-1/+1
Running turbostat on a 16 socket HPE Scale-up Compute 3200 (SapphireRapids) fails with: turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_010_die_00/current_freq_khz: open failed: No such file or directory We observe the sysfs uncore frequency directories named: ... package_09_die_00/ package_10_die_00/ package_11_die_00/ ... package_15_die_00/ The culprit is an incorrect sprintf format string "package_0%d_die_0%d" used with each instance of reading uncore frequency files. uncore-frequency-common.c creates the sysfs directory with the format "package_%02d_die_%02d". Once the package value reaches double digits, the formats diverge. Change each instance of "package_0%d_die_0%d" to "package_%02d_die_%02d".

Graphics sysfs snapshots share similar logic. Combine them into one function to avoid code duplication. No functional change. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2024-04-09tools/power/turbostat: Cache graphics sysfs pathZhang Rui1-13/+32
Graphics drivers (i915/Xe) have different sysfs knobs on different platforms, and it is possible that different sysfs knobs fit into the same turbostat columns. Instead of specifying different sysfs knobs every time, detect them once and cache the path for future use. No functional change.
