2012-03-24gdbserver: Don't send a GDB syscall until the system CPU is stoppedMeador Inge1-15/+27
Fix an issue where the GDB server implementation was sending GDB syscall requests while the system CPU was still running. Syscall requests must be sent while the CPU is stopped otherwise replies from the GDB client might get dropped and the GDB server might be incorrectly transitioned into a 'RUN_STATE_PAUSED' state.

2012-03-24Support utf8 chars in pod docsMichael Tokarev2-4/+14
We've at least one UTF8 char in the qemu texi doc: $ grep Tibor qemu-doc.texi by Tibor "TS" Schütz. $ man ./qemu.1 | grep Tibor by Tibor "TS" SchA~Xtz. This patch allows utf8 in man/pod docs. Initially it was split into two parts and sent on 2012-02-02. Resending it again (3rd time) now in merged form. If any other generalizations of $(POD2MAN) are needed it can be done in a separate patch. Current form of $(POD2MAN) is choosen to be able to easily change it if some implementation does not support utf8 or resulting output has issues with local man(1) program/macros. First, add @documentencoding in scripts/texi2pod.pl: Currently our texi2pod ignores @documentencoding even if it is set properly in *.texi files. This results in a mojibake in documents generated from qemu.pod (which is generated from qemu-doc.texi by texi2pod), because the rest of the tools assumes ASCII encoding. This patch recognizes first @documentencoding in input and places it at the beginning of output as =encoding directive. Second, run pod2man with --utf8 option to enable utf8 in manpages: This option makes no difference for manpages which contains only ascii chars. But for manpages with actual UTF8 characters (qemu docs contains these), this change allows to see real characters instead of mojibakes or substitutes.

2012-03-24fix screendumpGerd Hoffmann3-7/+4
Commit 45efb16124efef51de5157afc31984b5a47700f9 optimized a bit too much. We can skip the vga_invalidate_display() in case no console switch happened because we don't need a full redraw then. We can *not* skip vga_hw_update() though, because the screen content will be stale then in case nobody else calls vga_hw_update(). Trigger: vga textmode with vnc display and no client connected.

2012-03-19xen mapcache: check if memory region has moved.Anthony PERARD3-6/+43
This patch changes the xen_map_cache behavior. Before trying to map a guest addr, mapcache will look into the list of range of address that have been moved (physmap/set_memory). There is currently one memory space like this, the vram, "moved" from were it's allocated to were the guest will look into. This help to have a succefull migration.

Changes in v8: - rename save-devices-state to xen-save-devices-state. Changes in v7: - rename save_devices to save-devices-state. Changes in v6: - remove the is_ram parameter from register_savevm_live and sets is_ram if the device is a live_savevm device; - introduce save_devices as a QAPI command, write a better description for it; - fix CODING_STYLE; - introduce a new doc to explain the save format used by save_devices.

2012-03-19scsi: copy serial number into VPD page 0x83Paolo Bonzini1-3/+4
Currently QEMU passes the qdev device id to the guest in an ASCII-string designator in page 0x83. While this is fine, it does not match what real hardware does; usually the ASCII-string designator there hosts another copy of the serial number (there can be other designators, for example with a world-wide name). Do the same for QEMU SCSI disks. ATAPI does not support VPD pages, so it does not matter there. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-03-19scsi-cd: check ready condition before processing several commandsPaolo Bonzini1-13/+29
This commit is more or less obvious. What it caused is less obvious: SCSI CD drives failed to eject under Linux, though for example the "change" command worked okay. This happens because of the autoclose option in the Linux CD-ROM driver. The actual chain of events is quite complex and somehow involves udev helpers; the actual command that matters is READ TOC, though honestly it's not really clear to me how because it should always be invoked after autoclose, not before.

2012-03-19spice: fix broken initializationAlon Levy2-8/+6
Commit 1b71f7c14fab6f00c2680d4489fbee7baf796e4f moved MODULE_INIT_QOM to way before MODULE_INIT_MACHINE, thereby breaking assumptions made in spice-core.c which registered both a type initializer and a machine intializer. This fix removes the type registration, and replaces it with calling qemu_spice_init in vl.c after command line parsing (second pass) is done, and after timers are armed, required by spice server.
