[Qemu-devel] [PATCH v3 14/22] memory-device: trace when pre_assigning/assigning/unassigning addresses |
Date: |
Thu, 20 Sep 2018 12:32:35 +0200 |
Let's trace the address when pre_pluggin/plugging/unplugging a memory device.
Trace it when pre_plugging as well as when plugging, so we really know
when a specific address is actually used.
