From 18f0828278c62bf5b50ec24a012073cd79535481 Mon Sep 17 00:00:00 2001 From: Suraj Jitindar Singh Date: Thu, 8 Jun 2017 15:41:16 +1000 Subject: monitor: Add -a (all) option to info registers The info registers command in the qemu monitor is used to dump register values. Currently this command uses the monitor cpu (which can be set by the user) as the cpu for whose registers will be dumped. Sometimes it is useful to see the registers for all cpus and currently this requires setting the monitor cpu and the re-running the command for each cpu in the system. I would be nice if there was an easier way to do this. Add the "-a" option to the info registers command to dump the register values for all cpus.
