X-Received-From: 2607:f8b0:400e:c05::244 Subject: [Qemu-devel] [PATCH] hmp-commands: use long for begin and length in dump-guest-memory X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Suraj Jitindar Singh , dgilbert@redhat.com, Suraj Jitindar Singh Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) X-ZohoMail: RDKM_2 RSF_0 Z_629925259 SPT_0 Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" The dump-guest-memory command is used to dump an area of guest memory to a file, the piece of memory is specified by a begin address and a length. These parameters are specified as ints and thus have a maximum value of 4GB. This means you can't dump the guest memory past the first 4GB and instead get: (qemu) dump-guest-memory tmp 0x100000000 0x100000000 'dump-guest-memory' has failed: integer is for 32-bit values Try "help dump-guest-memory" for more information This limitation is imposed in monitor_parse_arguments() since they are both ints. hmp_dump_guest_memory() uses 64 bit quantities to store both the begin and length values. Thus specify begin and length as long so that the entire guest memory space can be dumped.
