Crossplatform Vlad Posted April 14 Posted April 14 Build logs: https://paste.armbian.com/ivisomijaq Please take a look on CPU usage precision on the new kernel for x64 and arm64. It is 1 milliseconds. But kernel 6.13 on armv7 still provides 4 milliseconds of precision. How do I tune CPU usage precision on image build? 0 Quote
Crossplatform Vlad Posted Saturday at 11:16 PM Author Posted Saturday at 11:16 PM Seems Ubuntu from Canonical uses a customized kernel where CPU usage precision is improved. But Debian and Armbian use previous CPU usage precision settings? 0 Quote
laibsch Posted Monday at 01:31 PM Posted Monday at 01:31 PM Can you point to a patch or some code from Ubuntu how they achieve that? 0 Quote

hexdump Posted Monday at 07:38 PM Posted Monday at 07:38 PM maybe its related to the kernel config parameter CONFIG_HZ_xyz - depending on which of them is set for the different kernels? 0 Quote
