[ 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".

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
