2011-12-19etraxfs_eth: drop bogus cpu_unregister_io_memory()Avi Kivity1-3/+0
Leftover call to cpu_unregister_io_memory() can segfault on cleanup. Remove. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-19memory, xen: pass MemoryRegion to xen_ram_alloc()Avi Kivity1-1/+3
Currently xen_ram_alloc() relies on ram_addr, which is going away. Give it something else to use as a cookie. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-12-19pc: fix event_idx compatibility for virtio devicesAnthony Liguori1-0/+32
event_idx was introduced in 0.15 and must be disabled for all virtio-pci devices (including virtio-balloon-pci). Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-19Also create piix3 property when Xen is enabledJulian Pidancet1-2/+1
This recently added line in hw/pc_piix.c is causing a SEGV on a Xen setup because the piix3 property is never created: qdev_property_add_child(qdev_resolve_path("/i440fx/piix3", NULL), "rtc", (DeviceState *)rtc_state, NULL); Signed-off-by: Julian Pidancet <julian.pidancet@gmail.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2011-12-16stellaris: Calculate system clock period on resetPeter Maydell1-0/+1
Calculate the system clock period on reset; otherwise it remains set to the default value of zero and attempting to use it provokes a hang. This is one of the issues noted in LP:696094.

2011-12-16ide: drop argument to dma_buf_commitPaolo Bonzini1-3/+3
The argument is unused and even wrong when the function is called by ide_handle_rw_error. Drop it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-12-15usb: fix usb_qdev_init() error handling againStefan Hajnoczi1-7/+5
Commit f462141f18ffdd75847f6459ef83d90b831d12c0 introduced clean up code when usb_qdev_init() fails. Unfortunately it calls .handle_destroy() when .init() was never invoked or failed. This can lead to crashes when .handle_destroy() tries to clean up things that were never initialized. This patch is careful to undo only those steps that completed along the usb_qdev_init() code path. It's not as pretty as the unified error handling in f462141f18ffdd75847f6459ef83d90b831d12c0 but it's necessary.

2011-12-15qom: optimize qdev_get_canonical_path using a parent linkAnthony Liguori2-32/+28
The full tree search was a bit unreasonable. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15rtc: add a dynamic property for retrieving the dateAnthony Liguori1-0/+27
This really shows the power of dynamic object properties compared to qdev static properties. This property represents a complex structure who's format is preserved over the wire. This is enabled by visitors. It also shows an entirely synthetic property that is not tied to device state. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15rtc: make piix3 set the rtc as a child (v2)Anthony Liguori2-0/+14

Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qdev: add explicitly named devices to the root complexAnthony Liguori1-0/+14
We first add a 'peripheral' container to the root device that we add user created devices to. This provides all user created devices with a unique and isolated namespace. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: add link properties (v2)Anthony Liguori2-0/+97
Links represent an ephemeral relationship between devices. They are meant to replace the qdev concept of busses by allowing more informal relationships between devices. Links are fairly limited in their usefulness without implementing QOM-style subclassing and interfaces. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: add child properties (composition) (v3)Anthony Liguori2-0/+46
Child properties express a relationship of composition. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qdev: provide a path resolution (v2)Anthony Liguori2-0/+131
There are two types of supported paths--absolute paths and partial paths. Absolute paths are derived from the root device and can follow child<> or link<> properties. Since they can follow link<> properties, they can be arbitrarily long. Absolute paths look like absolute filenames and are prefixed with a leading slash. Partial paths are look like relative filenames. They do not begin with a prefix. The matching rules for partial paths are subtle but designed to make specifying devices easy. At each level of the composition tree, the partial path is matched as an absolute path. The first match is not returned. At least two matches are searched for. A successful result is only returned if only one match is founded. If more than one match is found, a flag is returned to indicate that the match was ambiguous. At the end of the day, partial path support means that if you create a device called 'ide0', you can just say 'ide0' as the path name and it will Just Work. If we internally create a device called 'i440fx', you can just say 'i440fx' and it will Just Work and long as you don't do anything silly. A management tool should probably always use absolute paths since then they don't have to deal with the possibility of ambiguity. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qdev: provide an interface to return canonical path from root (v2)Anthony Liguori2-0/+57
The canonical path is the path in the composition tree from the root to the device. This is effectively the name of the device. This is an incredibly unefficient implementation that will be optimized in a future patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: introduce root deviceAnthony Liguori3-0/+40
This is based on Jan's suggestion for how to do unique naming. The root device is the root of composition. All devices are reachable via child<> links from this device. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: register legacy properties as new style properties (v2)Anthony Liguori2-0/+93
Expose all legacy properties through the new QOM property mechanism. The qdev property types are exposed through the 'legacy<>' namespace. They are always visited as strings since they do their own string parsing. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: add new dynamic property infrastructure based on Visitors (v2)Anthony Liguori2-0/+217
qdev properties are settable only during construction and static to classes. This isn't flexible enough for QOM. This patch introduces a property interface for qdev that provides dynamic properties that are tied to objects, instead of classes. These properties are Visitor based instead of string based too. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-15qom: add a reference count to qdev objectsAnthony Liguori2-0/+42
To ensure that a device isn't removed from the graph until all of its links are broken. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Initially attempted with the following semantic patch: @ rule1 @ expression E; statement S; @@ E = ( dma_bdrv_io | dma_bdrv_read | dma_bdrv_write ) (...); ( - if (E == NULL) { ... } | - if (E) { <...

2011-12-12ccid: make threads joinablePaolo Bonzini1-15/+11
Destroying a mutex that another thread might have just unlocked is racy. It usually works, but you cannot do that in general and can lead to deadlocks or segfaults. Change ccid to use joinable threads instead. (Also, qemu_mutex_init/qemu_cond_init were missing).

qemu_fclose() and QEMUFile->close will return -errno on error, and any positive value on success.
