| Summary | 0005135: CPU Freq governor is set to "performance" by default. | ||||
| Description | Previously, the CPU Freq governor was set to "interactive" by default. This is a power saving mode, which will only use high freqs on high loads and user input. This mode has been removed in kernel 5.4.3.2.0.0, so now the default value "performance" is used, which will alway use the maximal fequency available. This might lead to power consumption issues for power senisitive applications. | ||||

Git commit: 5400e642aabdb66e7a38e1422e265208b071f65b Fix armv7 default cpu frequency governor Previously, the CPU Freq governor was set to "interactive" by default. This is a power saving mode, which will only use high frequencies on high loads and user input. This mode has been removed in kernel 5.4.3.2.0.0, so now the default value "performance" is used, which will alway use the maximal frequency available. This leads to a higher energy consumption. Now we use the "ondemand" governor, because it should be the closest to the old "interactive" governor. |
