[ Upstream commit 60add818ab2543b7e4f2bfeaacf2504743c1eb50 ]
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".
