[dpdk-dev] [PATCH v1] lib/power: add check for sysfs base frequency

2021-03-16 Thread David Hunt
Some kernels may show in incorrect value for base frequency in sysfs (e.g. 15 GHz). This throws off the SST-BF algorithm for high and low priority cores. So if base_frequency is greater than max turbo frequency, ignore, and handle it as a normal core. Known Kernel version with issue: Linux 5.8.7
