2011-07-20Avoid CPU endian memory accesses in devicesBlue Swirl4-10/+22

2011-07-18virtio-console: Prevent abort()s in case of host chardev closeAmit Shah1-1/+15
A host chardev could close just before the guest sends some data to be written. This will cause an -EPIPE error. This shouldn't be propagated to virtio-serial-bus. Ideally we should close the port once -EPIPE is received, but since the chardev interface doesn't return such meaningful values to its users, all we get is -1 for any kind of error. Just return 0 for now and wait for chardevs to return better error messages to act better on the return messages. Signed-off-by: Amit Shah <amit.shah@redhat.com>

2011-07-17vhost: fix double free on device stopMichael S. Tsirkin1-0/+1
vhost dev stop failed to clear the log field. Typically not an issue as dev start overwrites this field, but if logging gets disabled before the following start, it doesn't so this causes a double free. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-07-17xen_console: fall back to qemu serial deviceAlexander Graf1-4/+7
The new xen_console protocol changed the default xen_console output device from whatever Qemu chose to whatever xenstore choses and "pty" as fallback. This is not how Qemu works. It has its own serial redirection semantics. So it xenstore doesn't contain information on what to do, Qemu is the place to ask. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-07-17xen_console: support the new extended xenstore protocolStefano Stabellini5-6/+87
Since CS 21994 on xen-unstable.hg and CS 466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few changes have been introduced to the PV console xenstore protocol, as described by the document docs/misc/console.txt under xen-unstable.hg. From the Qemu point of view, very few modifications are needed to correctly support the protocol: read from xenstore the "output" node that tell us what the output of the PV console is going to be. In case the output is a tty, write to xenstore the device name. Changes in v2: - fix error paths: free malloc'ed strings and close the xenstore connection before returning; - remove useless snprintf in xenstore_store_pv_console_info if i == 0. Changes in v3: - replace xs_daemon_open/xs_daemon_close with xs_open/xs_close. Changes in v4: - add a compatibility implementation of xs_open/xs_close. Changes in v5: - fix code style.

2011-07-17checkpatch: don't error out on },{ linesAlexander Graf1-1/+3
When having code like this: static PCIDeviceInfo piix_ide_info[] = { { .qdev.name = "piix3-ide", .qdev.size = sizeof(PCIIDEState), .qdev.no_user = 1, .no_hotplug = 1, .init = pci_piix_ide_initfn, .vendor_id = PCI_VENDOR_ID_INTEL, .device_id = PCI_DEVICE_ID_INTEL_82371SB_1, .class_id = PCI_CLASS_STORAGE_IDE, },{ .qdev.name = "piix4-ide", .qdev.size = sizeof(PCIIDEState), .qdev.no_user = 1, .no_hotplug = 1, .init = pci_piix_ide_initfn, .vendor_id = PCI_VENDOR_ID_INTEL, .device_id = PCI_DEVICE_ID_INTEL_82371AB, .class_id = PCI_CLASS_STORAGE_IDE, },{ /* end of list */ } }; checkpatch currently errors out, claiming that spaces need to follow commas. However, this particular style of defining structs is pretty common in qemu code and very readable. So let's declare it as supported for the above case.

2011-07-17qemu_ram_ptr_length: take ram_addr_t as argumentsStefano Stabellini2-8/+15
qemu_ram_ptr_length should take ram_addr_t as argument rather than target_phys_addr_t because is doing comparisons with RAMBlock addresses. cpu_physical_memory_map should create a ram_addr_t address to pass to qemu_ram_ptr_length from PhysPageDesc phys_offset. Remove code after abort() in qemu_ram_ptr_length. Changes in v2: - handle 0 size in qemu_ram_ptr_length; - rename addr1 to raddr; - initialize raddr to ULONG_MAX.

When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, ':') that caused the segfault; - free all the allocated strings from xenstore before returning; Updated in v3: - set blkdev fields to NULL after free'ing them.

2011-07-17xen: add vkbd support for PV on HVM guestsStefano Stabellini2-7/+13
Register the vkbd backend even when running as device emulator for HVM guests: it is useful because it doesn't need a frequent timer like usb. Check whether the XenInput DisplayState has been set in the initialise state, rather than the input state. In case the DisplayState hasn't been set and there is no vfb for this domain, then set the XenInput DisplayState to the default one.

2011-07-17xen: Fold CONFIG_XEN_MAPCACHE into CONFIG_XENJan Kiszka4-58/+9

2011-07-16Fix signal handling of SIG_IPI when io-thread is enabledAlexandre Raymond1-1/+9
Both the signal thread (via sigwait()) and the cpu thread (via a normal signal handler) were attempting to catch SIG_IPI. This resulted in random freezes under Darwin. This patch separates SIG_IPI from the rest of the signals handled by the signal thread, because it is independently caught by the cpu thread.

2011-07-16Fix signal handling when io-thread is disabledAlexandre Raymond1-1/+1
Changes since v1: - take pthread_sigmask() out of the ifdef as it is now common to both parts. This fix effectively blocks, in the main thread, the signals handled by signalfd or the compatibility signal thread. This way, such signals are received synchronously in the main thread through sigfd_handler() instead of triggering the signal handler directly, asynchronously.
