Hello Gregory! Patches are the for almost two months and more people have tested them. They are marked with Fixed/CC-stable tags, they should go also into stable trees as they are fixing CPU scaling and instability issues. Are there any issues with these patches? If not, could you please merge them for upcoming Linux version? On Monday 22 February 2021 20:41:48 Pali Rohár wrote:
Hello! This is third version of patches for Armada 37xx cpufreq driver which fix CPU scaling with 1 GHz base frequency. The only change in this third version is modified patch 04/10 with fixes for 1.2 GHz variant of Espressobin. Minimal CPU voltage in L1 load for 1.2 GHz variant was increased to 1.155V. Patches are now rebased on top of the kernel version 5.11 with all collected Acked-by/Tested-by lines and are available also in my git tree in branch a3720-cpufreq-issues: https://git.kernel.org/pub/scm/linux/kernel/git/pali/linux.git/log/?h=a3720-cpufreq-issues If you have other Armada 3720 boards with 1.2 GHz CPU, including Espressobin V7, let us know if it is working fine for you.
