[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3 10/10] xen/arm: Implement toolstack for xl restore/save and migrate
From: Alexey Sokolov <sokolov.a@xxxxxxxxxxx>
Implement for xl restore/save (which are also used for migrate)
operation in xc_arm_migrate.c and make it compilable.
The overall process of save is the following:
1) save guest parameters (i.e., memory map, console and store pfn, etc)
2) save memory (if it is live, perform dirty-page tracing)
3) save hvm states (i.e., gic, timer, etc)
4) save vcpu registers (i.e., pc, sp, lr, etc)
The overall process of restore is the same to the one in save.
Singed-off-by: Alexey Sokolov <sokolov.a@xxxxxxxxxxx>
