* qmp/hmp: add rocker device supportScott Feldman2015-06-121-0/+24

* monitor: Use trad. command interface for HMP pcie_aer_inject_errorMarkus Armbruster2015-06-021-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. pcie_aer_inject_error's implementation is split into the hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The former is a peculiar crossbreed between HMP and QMP handler. On success, it works like a QMP handler: store QDict through ret_data parameter, return 0. Printing the QDict is left to pcie_aer_inject_error_print(). On failure, it works more like an HMP handler: print error to monitor, return negative number. To convert to the traditional interface, turn pcie_aer_inject_error_print() into a command handler wrapping around hmp_pcie_aer_inject_error(). By convention, this command handler should be called hmp_pcie_aer_inject_error(), so rename the existing hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

* monitor: Make client_migrate_info synchronousMarkus Armbruster2015-04-271-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | Live migration with spice works like this today: (1) client_migrate_info monitor cmd (2) spice server notifies client, client connects to target host. (3) qemu waits until spice client connect is finished. (4) send over vmstate (i.e. main part of live migration). (5) spice handover to target host. (3) is implemented by making client_migrate_info a async monitor command. This is the only async monitor command we have. The original reason to implement this dance was that qemu did not accept new tcp connections while the incoming migration was running, so (2) and (4) could not be done in parallel. That issue was fixed long ago though. Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp connects while the incoming migration runs. Time to drop step (3). This patch does exactly that, by making the monitor command synchronous and removing the code needed to handle the async monitor command in ui/spice-core.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* hmp: Fix definition of command quitMarkus Armbruster2015-03-191-1/+0Star
| | | | | | | | | | | | | | | | | | | | | The command handler is a union of two function types. If cmd->user_print is set, handle_user_command() calls cmd->mhandler.cmd_new(), else cmd->mhandler.cmd(). Command definitions must therefore either set both user_print() and mhandler.cmd_new(), or only mhandler.cmd(). quit's sets user_print and mhandler.cmd(). handle_user_command() calls hmp_quit() through mhandler.cmd_new() rather than mhandler.cmd(), i.e. through a function pointer with a different type. Broken in commit 7a7f325, v1.0. Works in practice because hmp_quit() doesn't use its arguments, and handle_user_command() ignores its function value.

So this command doesn't really tell anybody anything new so far. Moreover, pcmcia_socket_unregister() has a use-after-free bug, flagged by Coverity. Has never been used, because there has never been code to eject a PCMCIA card. Not worth fixing & converting to QMP. Remove it.

| | | | | | | | | | | | | | | | | | | | | | This introduces an NMI (Non Maskable Interrupt) interface with a single nmi_monitor_handler() method. A machine or a device can implement it. This searches for an QOM object with this interface and if it is implemented, calls it. The callback implements an action required to cause debug crash dump on in-kernel debugger invocation. The callback returns Error**. This adds a nmi_monitor_handle() helper which walks through all objects to find the interface. The interface method is called for all found instances. This adds support for it in qmp_inject_nmi(). Since no architecture supports it at the moment, there is no change in behaviour. This changes inject-nmi command description for HMP and QMP.

* monitor: add object-add (QMP) and object_add (HMP) commandPaolo Bonzini2014-01-061-0/+14
| | | | | | | | | | | | Add two commands that are the monitor counterparts of -object. The commands have the same Visitor-based implementation, but use different kinds of visitors so that the HMP command has a DWIM string-based syntax, while the QMP variant accepts a stricter JSON-based properties dictionary.

* net: Adding netmap network backendVincenzo Maffione2013-12-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for a network backend based on netmap. netmap is a framework for high speed packet I/O. You can use it to build extremely fast traffic generators, monitors, software switches or network middleboxes. Its companion software switch VALE lets you interconnect virtual machines. netmap and VALE are implemented as a non-intrusive kernel module, support NICs from multiple vendors, are part of standard FreeBSD distributions and available in source format for Linux too. To compile QEMU with netmap support, use the following configure options: ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys where "/path/to/netmap" contains the netmap source code, available at http://info.iet.unipi.it/~luigi/netmap/ The same webpage contains more information about the netmap project (together with papers and presentations).

* | s390: wire up nmi command to raise a RESTART interrupt on S390Eugene (jno) Dvurechenski2013-08-301-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | There is the 'nmi' command that is used to trigger a guest dump via kdump feature on x86. s390 uses RESTART interrupt to trigger kdump. So, this patch provides a mean to use 'nmi' command on s390 to raise RESTART interrupt. The CPU to receive the RESTART interrupt is the "default" one. There is an infrastructure to select the "default" CPU using 'cpu' command. The 'info cpus' command can be used to see which one is the "default". In order to wire up the RESTART to 'nmi' command we had to: 1. implement the kvm_s390_cpu_restart function by exporting the existing code 2. implement s390_cpu_restart function as kvm-aware wrapper 3. modify the qmp_inject_nmi function to enable (for s390) the scan for "default" CPU and call s390_cpu_restart for it; 3. fix some messages.

* block: add drive_backup HMP commandStefan Hajnoczi2013-07-151-0/+20
| | | | | | | | | | | | | | | | | | | Make "drive_backup" available on the HMP monitor: drive_backup [-n] [-f] device target [format] The -n flag requests QEMU to reuse the image found in new-image-file, instead of recreating it from scratch. The -f flag requests QEMU to copy the whole disk, so that the result does not need a backing file. Note that this flag *must* currently be passed since the other sync modes ('none' and 'top') have not been implemented yet. Requiring it ensures that "drive_backup" behaves like "drive_mirror".

* pci: Cleanup configuration for pci-hotplug.cDavid Gibson2013-07-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its compilation are misnamed. They're not about PCI hotplug in general, but rather about the pci_add/pci_del interface which are now deprecated in favour of the more general device_add/device_del interface. This patch therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD. CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no particular reason, so we clean that up too. In addition it was included in ppc64-softmmu.mak for which the old hotplug interface was never used and is unsuitable, so we remove that too. Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386. The small piece which wasn't is only called from the pci_add and pci_del hooks in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386. This patch therefore also removes the #ifdef from pci-hotplug-old.c, and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

* dump: Drop qmp_dump_guest_memory() stub and build for all targetsAndreas Färber2013-06-111-2/+0Star
| | | | | | | | | | | | | qmp_dump_guest_memory() calls dump_init() and returns an Error when cpu_get_dump_info() returns an error, as done by the stub. So there is no need to have a stub for qmp_dump_guest_memory(). Enable the documentation of the always-present dump-guest-memory command. That way we can drop CONFIG_HAVE_CORE_DUMP and leave configure completely out of the picture for target CPU features. Signed-off-by: Andreas Färber <afaerber@suse.de>
