a/pkgtools-15.0-noarch-39.txz: Rebuilt. upgradepkg: revert change where $ROOT/sbin/installpkg is called instead of /sbin/installpkg. Conceptually, this seemed like a nice change (but would have also required removepkg to be called the same way), but it seems to break an established expectation that the pkgtools can be used without them actually being installed in $ROOT. Thanks to alienBOB. a/sysvinit-scripts-15.0-noarch-2.txz: Rebuilt. Use #!/bin/bash for these scripts so that bashisms don't cause script issues if /bin/sh is some other shell. Thanks to mumahendras3. rc.S: Use GazL's proposals for detecting/mounting /proc and /sys. d/parallel-20210422-noarch-1.txz: Upgraded. l/glib-networking-2.68.1-x86_64-1.txz: Upgraded. l/gtk+3-3.24.29-x86_64-1.txz: Upgraded. x/igt-gpu-tools-1.26-x86_64-1.txz: Upgraded. isolinux/initrd.img: Rebuilt. Rebuild with pkgtools-15.0-noarch-39. usb-and-pxe-installers/usbboot.img: Rebuilt. Rebuild with pkgtools-15.0-noarch-39.

# rc.cpufreq: Settings for CPU frequency and voltage scaling in the kernel.

# For more information, see the kernel documentation in

# /usr/src/linux/Documentation/cpu-freq/
|

|
|
|
|
# Default CPU scaling governor to try. Some possible choices are:
|
|
# performance: The CPUfreq governor "performance" sets the CPU statically
|
|
# to the highest frequency within the borders of scaling_min_freq
|
|
# and scaling_max_freq.
|
|
# powersave: The CPUfreq governor "powersave" sets the CPU statically to the
|
|
# lowest frequency within the borders of scaling_min_freq and
|
|
# scaling_max_freq.
|
|
# userspace: The CPUfreq governor "userspace" allows the user, or any
|
|
# userspace program running with UID "root", to set the CPU to a
|
|
# specific frequency by making a sysfs file "scaling_setspeed"
|
|
# available in the CPU-device directory.
|
|
# ondemand: The CPUfreq governor "ondemand" sets the CPU depending on the
|
|
# current usage.
|
|
# conservative: The CPUfreq governor "conservative", much like the "ondemand"
|
|
# governor, sets the CPU depending on the current usage. It
|
|
# differs in behaviour in that it gracefully increases and
|
|
# decreases the CPU speed rather than jumping to max speed the
|
|
# moment there is any load on the CPU.
|
|
# schedutil: The CPUfreq governor "schedutil" aims at better integration with
|
|
# the Linux kernel scheduler. Load estimation is achieved through
|
|
# the scheduler's Per-Entity Load Tracking (PELT) mechanism, which
|
|
# also provides information about the recent load.
