From d0f63c1e291a0c27cafc0e6faec5a84130b012e0 Mon Sep 17 00:00:00 2001 From: Vadim Galitsyn Date: Tue, 29 Aug 2017 17:30:22 +0200 Subject: [PATCH] hmp: introduce 'info memory_size_summary' command Add 'info memory_size_summary' command which is a sibling of QMP command query-memory-size-summary. It provides the following memory information in bytes: * base-memory - size of "base" memory specified with command line option -m. * plugged-memory - amount of memory that was hot-plugged. If target does not have CONFIG_MEM_HOTPLUG enabled, no value is reported.
