You will be running in SVC mode, so the SVC mode registers are your current register set. At some point you need to do an effective "context switch" between the kernel doing the resume and the kernel which was running. That involves restoring the saved register state. System mode on the other hand is unused by the kernel. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
