2009-08-10qdev-ify virtio-blk.Gerd Hoffmann
First user of the new drive property. With this patch applied host and guest config can be specified separately, like this: -drive if=none,id=disk1,file=/path/to/disk.img -device virtio-blk-pci,drive=disk1 You can set any property for virtio-blk-pci now. You can set the pci address via addr=. You can switch the device into 0.10 compat mode using class=0x0180. As this is per device you can have one 0.10 and one 0.11 virtio block device in a single virtual machine. Old syntax continues to work. Internally it does the same as the two lines above though. One side effect this has is a different initialization order, which might result in a different pci address being assigned by default. Long term plan here is to have this working for all block devices, i.e. once all scsi is properly qdev-ified you will be able to do something like this: -drive if=none,id=sda,file=/path/to/disk.img -device lsi,id=lsi,addr=<pciaddr> -device scsi-disk,drive=sda,bus=lsi.0,lun=<n> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
2009-07-27kill drives_tableGerd Hoffmann
First step cleaning up the drives handling. This one does nothing but removing drives_table[], still it became seriously big. drive_get_index() is gone and is replaced by drives_get() which hands out DriveInfo pointers instead of a table index. This needs adaption in *tons* of places all over. The drives are now maintained as linked list. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-29monitor: Drop pci_addr prefix from hotplug commandsJan Kiszka
The "pci_addr=" prefix currently required by pci_add/remove and drive_add has no practical use. Drop it, but still silently accept it for backward compatibility. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-22Support addr=... in option argument of -drive if=virtioMarkus Armbruster
Make drive_init() accept addr=, put the value into struct DriveInfo. Use it in all the places that create virtio-blk-pci devices: pc_init1(), bamboo_init(), mpc8544ds_init(). Don't support addr= in third argument of monitor command pci_add and second argument of drive_add, because that clashes with their first arguments. Admittedly unelegant.

2009-06-22Make first argument of monitor command pci_add workMarkus Armbruster
Simply pass the PCI address through qemu_pci_hot_add_nic() to pci_nic_init() and through qemu_pci_hot_add_storage() to pci_create(). Before, pci_device_hot_add() passed along the PCI bus to use, and ignored any user-specified slot.

2009-06-22Support addr=... in option argument of -net nicMarkus Armbruster
Make net_client_init() accept addr=, put the value into struct NICinfo. Use it in pci_nic_init(), and remove arguments bus and devfn. Don't support addr= in third argument of monitor command pci_add, because that clashes with its first argument. Admittedly unelegant. Machines "malta" and "r2d" have a default NIC with a well-known PCI address. Deal with that the same way as the NIC model: make pci_nic_init() take an optional default to be used when the user doesn't specify one.

2009-06-09net: Improve parameter error reportingJan Kiszka
As host network devices can also be instantiated via the monitor, errors should then be reported to the related monitor instead of stderr. This requires larger refactoring, so this patch starts small with introducing a helper to catch both cases and convert net_client_init as well as net_slirp_redir.

2009-04-17Don't fail PCI hotplug if no NIC model is supplied (Mark McLoughlin)aliguori
It's perfectly fine to not supply a NIC model when adding a new NIC - we supply the default model to pci_nic_init() and it uses that if one wasn't explicitly supplied.

2009-04-05pci_add storage: fix error handling for 'if' parameter (Eduardo Habkost)aliguori
This fixes: - The error message to show the actual if= argument value. It was showing the filename instead, because 'buf' is reaused on the filename parsing. - A bug that makes a block device to be created even when an unsupported if= arg is passed to pci_add.

2009-03-05monitor: Rework API (Jan Kiszka)aliguori
Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.

2009-02-11qemu: PCI device, disk and host network hot-add / hot-remove (Marcelo Tosatti)aliguori
Add monitor command to hot-add PCI devices (nic and storage). Syntax is: pci_add pci_addr=[[<domain>:]<bus>:]<slot> nic|storage params It returns the domain, bus and slot for the newly added device on success. It is possible to attach a disk to a device after PCI initialization via the drive_add command. If so, a manual scan of the SCSI bus on the guest is necessary. Save QEMUMachine necessary for drive_init. Add monitor command to hot-remove devices, remove device data on _EJ0 notification.
