2025-11-24tools/power x86_energy_perf_policy: Prefer driver HWP limitsLen Brown1-4/+9
[ Upstream commit 2734fdbc9bb8a3aeb309ba0d62212d7f53f30bc7 ] When we are successful in using cpufreq min/max limits, skip setting the raw MSR limits entirely. This is necessary to avoid undoing any modification that the cpufreq driver makes to our sysfs request. eg. intel_pstate may take our request for a limit that is valid according to HWP.CAP.MIN/MAX and clip it to be within the range available in PLATFORM_INFO.

2025-11-24tools/power x86_energy_perf_policy: Fix incorrect fopen mode usageKaushlendra Kumar1-2/+2
[ Upstream commit 62127655b7ab7b8c2997041aca48a81bf5c6da0c ] The fopen_or_die() function was previously hardcoded to open files in read-only mode ("r"), ignoring the mode parameter passed to it. This patch corrects fopen_or_die() to use the provided mode argument, allowing for flexible file access as intended. Additionally, the call to fopen_or_die() in err_on_hypervisor() incorrectly used the mode "ro", which is not a valid fopen mode. This is fixed to use the correct "r" mode.

2025-11-24tools/cpupower: Fix incorrect size in cpuidle_state_disable()Kaushlendra Kumar1-2/+3
[ Upstream commit 23199d2aa6dcaf6dd2da772f93d2c94317d71459 ] Fix incorrect size parameter passed to cpuidle_state_write_file() in cpuidle_state_disable(). The function was incorrectly using sizeof(disable) which returns the size of the unsigned int variable (4 bytes) instead of the actual length of the string stored in the 'value' buffer. Since 'value' is populated with snprintf() to contain the string representation of the disable value, we should use the length returned by snprintf() to get the correct string length for writing to the sysfs file. This ensures the correct number of bytes is written to the cpuidle state disable file in sysfs.

2025-11-24tools/cpupower: fix error return value in cpupower_write_sysfs()Kaushlendra Kumar1-1/+1
[ Upstream commit 57b100d4cf14276e0340eecb561005c07c129eb8 ] The cpupower_write_sysfs() function currently returns -1 on write failure, but the function signature indicates it should return an unsigned int. Returning -1 from an unsigned function results in a large positive value rather than indicating an error condition. Fix this by returning 0 on failure, which is more appropriate for an unsigned return type and maintains consistency with typical success/failure semantics where 0 indicates failure and non-zero indicates success (bytes written).

[ Upstream commit cda7ac8ce7de84cf32a3871ba5f318aa3b79381e ] In the function mperf_start(), mperf_monitor snapshots the time, tsc and finally the aperf,mperf MSRs. However, this order of snapshotting in is reversed in mperf_stop(). As a result, the C0 residency (which is computed as delta_mperf * 100 / delta_tsc) is under-reported on CPUs that is 100% busy. Fix this by snapshotting time, tsc and then aperf,mperf in mperf_stop() in the same order as in mperf_start().

2024-05-17tools/power turbostat: Increase the limit for fd openedWyes Karny1-0/+21
[ Upstream commit 3ac1d14d0583a2de75d49a5234d767e2590384dd ] When running turbostat, a system with 512 cpus reaches the limit for maximum number of file descriptors that can be opened. To solve this problem, the limit is raised to 2^15, which is a large enough number. Below data is collected from AMD server systems while running turbostat: |-----------+-------------------------------| | # of cpus | # of opened fds for turbostat | |-----------+-------------------------------| | 128 | 260 | |-----------+-------------------------------| | 192 | 388 | |-----------+-------------------------------| | 512 | 1028 | |-----------+-------------------------------| So, the new max limit would be sufficient up to 2^14 cpus (but this also depends on how many counters are enabled).

2023-07-19cpupower: Fix cpuidle_set to accept only numeric values for idle-set operation.Likhitha Korrapati1-9/+7
For both the d and e options in 'cpupower idle_set' command, an atoi() conversion is done without checking if the input argument is all numeric. So, an atoi conversion is done on any character provided as input and the CPU idle_set operation continues with that integer value, which may not be what is intended or entirely correct. The output of cpuidle-set before patch is as follows: [root@xxx cpupower]# cpupower idle-set -e 1$ Idlestate 1 enabled on CPU 0 [snip] Idlestate 1 enabled on CPU 47 [root@xxx cpupower]# cpupower idle-set -e 11 Idlestate 11 not available on CPU 0 [snip] Idlestate 11 not available on CPU 47 [root@xxx cpupower]# cpupower idle-set -d 12 Idlestate 12 not available on CPU 0 [snip] Idlestate 12 not available on CPU 47 [root@xxx cpupower]# cpupower idle-set -d qw Idlestate 0 disabled on CPU 0 [snip] Idlestate 0 disabled on CPU 47 This patch adds a check for both d and e options in cpuidle-set.c to see that the idle_set value is all numeric before doing a string-to-int conversion using strtol(). The output of cpuidle-set after the patch is as below: [root@xxx cpupower]# ./cpupower idle-set -e 1$ Bad idle_set value: 1$. Integer expected [root@xxx cpupower]# ./cpupower idle-set -e 11 Idlestate 11 not available on CPU 0 [snip] Idlestate 11 not available on CPU 47 [root@xxx cpupower]# ./cpupower idle-set -d 12 Idlestate 12 not available on CPU 0 [snip] Idlestate 12 not available on CPU 47 [root@xxx cpupower]# ./cpupower idle-set -d qw Bad idle_set value: qw.

2023-05-08cpupower: Make TSC read per CPU for Mperf monitorWyes Karny1-17/+14
System-wide TSC read could cause a drift in C0 percentage calculation. Because if first TSC is read and then one by one mperf is read for all cpus, this introduces drift between mperf reading of later CPUs and TSC reading. To lower this drift read TSC per CPU and also just after mperf read. This technique improves C0 percentage calculation in Mperf monitor.
