- Previously, the cpuspeed daemon used a naive method of getting the highest available scaling frequency. Consequently, on certain platforms, cpuspeed did not set the CPU to the correct maximum limit. A patch has been provided to address this issue and cpuspeed now sets the maximum speed correctly.
- Prior to this update, the PCC driver used the “userspace” governor was loaded instead of the “ondemand” governor when loading. This update modifies the init script to also check the PCC driver.
- Prior to this update, the cpuspeed init script tried to set cpufrequency system files on a per core basis which was a deprecated procedure. This update sets thresholds globally.
- Prior to this update, the cpuspeed tool did not reset MIN and MAX values, when the configuration file was emptied. As a consequence, the MIN_SPEED or MAX_SPEED values were not reset as expected. This update adds conditionals in the init script to check these values. Now, the MIN_SPEED or MAX_SPEED values are reset as expected.
- Prior to this update, the init script did not handle the IGNORE_NICE parameter as expected. As a consequence, "-n" was added to command options when the IGNORE_NICE parameter was set. This update modifies the init script to stop adding the NICE option when using the IGNORE_NICE parameter.
- The cpuspeed init script relied on the presence of the scaling_available_frequencies sysfs file to get the maximum possible scaling frequency for the system. Certain platforms did not provide the scaling_available_frequencies sysfs file, which caused the attempt to set the maximum scaling frequency to fail. With this update, the init script now reads the frequency from cpuinfo_max_speed, and setting the maximum scaling frequency now works on all platforms.
