[$] Memory persistence over kexec
Tuesday April 1, 2025. 04:00 PM , from LWN.net
The kernel's kexec
mechanism allows one kernel to directly boot a new one; it can be thought of as a sort of kernel equivalent to the execve() system call. Kexec has a number of uses, including booting a special kernel to perform dumps after a crash. Normally, one does not expect user-space processes to survive booting into a new kernel, but that has not stopped developers from trying to implement that ability. Mike Rapoport ran a memory-management-track session at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit to discuss one piece of that problem: enabling the contents of memory to persist across a kexec handover so that the new kernel can pick up where the old one left off.
