2017-04-21xen: use libxendevice model to restrict operationsPaul Durrant
This patch adds a command-line option (-xen-domid-restrict) which will use the new libxendevicemodel API to restrict devicemodel [1] operations to the specified domid. (Such operations are not applicable to the xenpv machine type). This patch also adds a tracepoint to allow successful enabling of the restriction to be monitored. [1] I.e. operations issued by libxendevicemodel. Operation issued by other xen libraries (e.g. libxenforeignmemory) are currently still unrestricted but this will be rectified by subsequent patches.

This optimization is not necessary anymore, because the vCPU now drops the I/O thread lock even with TCG. Drop it to simplify the code and avoid the "I/O thread spun for 1000 iterations" warning.

2017-03-07block: Initial implementation of -blockdevMarkus Armbruster
The new command line option -blockdev works like QMP command blockdev-add. The option argument may be given in JSON syntax, exactly as in QMP. Example usage: -blockdev '{"node-name": "foo", "driver": "raw", "file": {"driver": "file", "filename": "foo.img"} }' The JSON argument doesn't exactly blend into the existing option syntax, so the traditional KEY=VALUE,... syntax is also supported, using dotted keys to do the nesting: -blockdev node-name=foo,driver=raw,file.driver=file,file.filename=foo.img This does not yet support lists, but that will be addressed shortly. Note that calling qmp_blockdev_add() (say via qmp_marshal_block_add()) right away would crash. We need to stash the configuration for later instead. This is crudely done, and bypasses QemuOpts, even though storing configuration is what QemuOpts is for. Need to revamp option infrastructure to support QAPI types like BlockdevOptions.

2017-03-05qmp: Dumb down how we run QMP command registrationMarkus Armbruster
The way we get QMP commands registered is high tech: * qapi-commands.py generates qmp_init_marshal() that does the actual work * it also generates the magic to register it as a MODULE_INIT_QAPI function, so it runs when someone calls module_call_init(MODULE_INIT_QAPI) * main() calls module_call_init() QEMU needs to register a few non-qapified commands. Same high tech works: monitor.c has its own qmp_init_marshal() along with the magic to make it run in module_call_init(MODULE_INIT_QAPI). QEMU also needs to unregister commands that are not wanted in this build's configuration (commit 5032a16). Simple enough: qmp_unregister_commands_hack(). The difficulty is to make it run after the generated qmp_init_marshal(). We can't simply run it in monitor.c's qmp_init_marshal(), because the order in which the registered functions run is indeterminate. So qmp_init_marshal() registers qmp_unregister_commands_hack() separately. Since registering *appends* to the list of registered functions, this will make it run after all the functions that have been registered already. I suspect it takes a long and expensive computer science education to not find this silly. Dumb it down as follows: * Drop MODULE_INIT_QAPI entirely * Give the generated qmp_init_marshal() external linkage. * Call it instead of module_call_init(MODULE_INIT_QAPI) * Except in QEMU proper, call new monitor_init_qmp_commands() that in turn calls the generated qmp_init_marshal(), registers the additional commands and unregisters the unwanted ones.

2017-03-03vl: disable default cdrom when using explicitely scsi-hdHervé Poussineau
In commit af6bf1328ef90fae617857c02697e0174b84d596 (May 2011), ide-hd, ide-cd and scsi-cd have been added to disable default cdrom, "or else you can't put one on secondary master without -nodefaults". Make it the same for scsi-hd, so you can put one on scsi-id 2 without using -nodefaults. scsi-hd has probably been forgotten, as it has been added in the preceding commit (b443ae67130d32ad06b06fc9aa6d04d05ccd93ce). Affected users are the ones using a machine with SCSI devices and start QEMU with -device scsi-hd but without -device scsi-cd or -cdrom In that case, the default cdrom device will disappear instead of being empty.

2017-02-21hw: Deprecate -drive if=scsi with non-onboard HBAsMarkus Armbruster
Block backends defined with "-drive if=T" with T other than "none" are meant to be picked up by machine initialization code: a suitable frontend gets created and wired up automatically. Drives defined with if=scsi are also picked up by SCSI HBAs added with -device, unlike other interface types. Deprecate this usage, as follows. Create the frontends for onboard HBAs in machine initialization code, exactly like we do for if=ide and other interface types. Change scsi_legacy_handle_cmdline() to create a frontend only when it's still missing, and warn that this usage is deprecated.

That's also not done for other interface types. I'm going to deprecate these SCSI eccentricities. In preparation for that, create the frontends in main() instead of the SCSI HBAs, by calling new function scsi_legacy_handle_cmdline() there. Note that not all SCSI HBAs create frontends.

2017-01-27chardev: qom-ifyMarc-André Lureau
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

You can override it with -drive and using the same index, but if you use -drive to add a floppy to a different index, you get both of them. However, as soon as you use any '-device floppy', even to a different slot, the default drive is disabled. Using '-device floppy' without specifying the unit will choose the first free slot on the controller.

2016-10-24cpu: Support a target CPU having a variable page sizePeter Maydell
Support target CPUs having a page size which isn't knownn at compile time. To use this, the CPU implementation should: * define TARGET_PAGE_BITS_VARY * not define TARGET_PAGE_BITS * define TARGET_PAGE_BITS_MIN to the smallest value it might possibly want for TARGET_PAGE_BITS * call set_preferred_target_page_bits() in its realize function to indicate the actual preferred target page size for the CPU (and report any error from it) In CONFIG_USER_ONLY, the CPU implementation should continue to define TARGET_PAGE_BITS appropriately for the guest OS page size. Machines which want to take advantage of having the page size something larger than TARGET_PAGE_BITS_MIN must set the MachineClass minimum_page_bits field to a value which they guarantee will be no greater than the preferred page size for any CPU they create. Note that changing the target page size by setting minimum_page_bits is a migration compatibility break for that machine. For debugging purposes, attempts to use TARGET_PAGE_SIZE before it has been finally confirmed will assert.

2016-10-24char: replace qemu_chr_claim/release with qemu_chr_fe_init/deinitMarc-André Lureau
Now that all front end use qemu_chr_fe_init(), we can move chardev claiming in init(), and add a function deinit() to release the chardev and cleanup handlers. The qemu_chr_fe_claim_no_fail() for property are gone, since the property will raise an error instead. In other cases, where there is already an error path, an error is raised instead. Finally, other cases are handled by &error_abort in qemu_chr_fe_init().

2016-10-17hw/arm/boot: allow using a command line specified dtb without a kernelMichael Olbrich
When kernel and device tree are specified in the QEMU commandline, then this device tree may be modified e.g. to add virtio_mmio devices. With a bootloader e.g. on a flash device these extra devices are not available. With this change, the device tree can be specified at the QEMU commandline. The modified device tree made available to the bootloader with the same mechanism already supported by device trees fully generated by QEMU.

machine_set_property() replaces '_' by '-' in the property name. Except it fails to replace an initial '_'. Screwed up in commit b0ddb8b. Reproducer: "-M pc,__foo_bar=true" produces "Property '._-foo-bar' not found". Error messages using a mangled name rather than the name the user actually wrote is user-hostile, but that's a different topic.

2016-10-12trace: provide mechanism for registering trace eventsDaniel P. Berrange
Remove the notion of there being a single global array of trace events, by introducing a method for registering groups of events. The module_call_init() needs to be invoked at the start of any program that wants to make use of the trace support. Currently this covers system emulators qemu-nbd, qemu-img and qemu-io. [Squashed the following fix from Daniel P. Berrange <berrange@redhat.com>: linux-user/bsd-user: initialize trace events subsystem The bsd-user/linux-user programs make use of the CPU emulation code and this now requires that the trace events subsystem is enabled, otherwise it'll crash trying to allocate an empty trace events bitmap for the CPU object. --Stefan] Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Daniel P.

2016-10-07block: Add bdrv_runtime_opts to query-command-line-optionsKevin Wolf
Recently we moved a few options from QemuOptsLists in blockdev.c to bdrv_runtime_opts in block.c in order to make them accissble using blockdev-add. However, this has the side effect that these options are missing from query-command-line-options now, and libvirt consequently disables the corresponding feature. This problem was reported as a regression for the 'discard' option, introduced in commit 818584a4. However, it is more general than that. Fix it by adding bdrv_runtime_opts to the list of QemuOptsLists that are returned in query-command-line-options. For the future, libvirt is advised to use QMP schema introspection for block device options.
