How to use CRIU to track memory changes and produce incremental dumps on ARM

[OwlCoHome]

hi，
I want to use CRIU to track memory changes and produce incremental dumps on ARM，When I run criu check --all，the results are as follows

My kernel version is linux 5.10.87,and the kernel does not support CONFIG_MEM_SOFT_DIRTY setting to Y because CONFIG_MEM_SOFT_DIRTY depends on HAVE_ARCH_SOFT_DIRTY

,ARM linux kernel does not select HAVE_ARCH_SOFT_DIRTY in Kconfig.

How to use CRIU to track memory changes and produce incremental dumps on ARM?

You are out of luck. Nobody implemented MEM_SOFT_DIRTY for ARM. As far as I know it only works on x86_64, ppc64le and s390x.

Somebody needs to implement it in the Linux kernel for ARM.
