2013-08-22aio / timers: Switch entire codebase to the new timer APIAlex Bligh1-9/+9
This is an autogenerated patch using scripts/switch-timer-api. Switch the entire code base to using the new timer API. Note this patch may introduce some line length issues. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-08-21loader: store FW CFG ROM files in RAMMichael S. Tsirkin1-3/+46
ROM files that are put in FW CFG are copied to guest ram, by BIOS, but they are not backed by RAM so they don't get migrated. Each time we change two bytes in such a ROM this breaks cross-version migration: since we can migrate after BIOS has read the first byte but before it has read the second one, getting an inconsistent state. Future-proof this by creating, for each such ROM, an MR serving as the backing store. This MR is never mapped into guest memory, but it's registered as RAM so it's migrated with the guest. Naturally, this only helps for -M 1.7 and up, older machine types will still have the cross-version migration bug. Luckily the race window for the problem to trigger is very small, which is also likely why we didn't notice the cross-version migration bug in testing yet. Signed-off-by: Michael S.

2013-08-07Bugfix for loading multiboot kernelsMartijn van den Broek1-4/+3
This patch fixes a bug in rom_copy introduced by commit d60fa42e8bae39440f997ebfe8fe328269a57d16. rom_copy failed to load roms with a "datasize" of 0. As a result, multiboot kernels were not loaded correctly when they contain a segment with a "file size" of 0. https://bugs.launchpad.net/qemu/+bug/1208944 Signed-off-by: Martijn van den Broek <martijn.vdbrk@gmail.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: CAG1x_oET1u3TMPu3r_zzd3ZXsTWQLiaM0zAc+RkHFCwvJjGOvg@mail.gmail.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.

2013-05-30qdev: fix get_fw_dev_path to support to add nothing to fw_dev_pathAmos Kong1-1/+9
Recent virtio refactoring in QEMU made virtio-bus become the parent bus of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation, typename will be added to fw_dev_path by default, the new fw_dev_path could not be identified by seabios. It causes that bootindex parameter of scsi device doesn't work. This patch implements get_fw_dev_path() in BusClass, it will be called if bus doesn't implement the method, tyename will be added to fw_dev_path. If the implemented method returns NULL, nothing will be added to fw_dev_path. It also implements virtio_bus_get_fw_dev_path() to return NULL. Then QEMU will still pass original style of fw_dev_path to seabios.

Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.

2013-04-15qdev: Fix QOM unrealize behaviorAndreas Färber1-7/+18
Since commit 249d41720b7dfbb5951b430b9eefdbee7464f515 (qdev: Prepare "realized" property) setting realized = true would register the device's VMStateDescription, but realized = false would not unregister it. Fix that. Moving the code from unparenting also revealed that we were calling DeviceClass::init through DeviceClass::realize as interim solution but DeviceClass::exit still at unparenting time with a realized check. Make this symmetrical by implementing DeviceClass::unrealize to call it, while we're setting realized = false in the unparenting path. The only other unrealize user is mac_nvram, which can safely override it. Thus, mark DeviceClass::exit as obsolete, new devices should implement DeviceClass::unrealize instead.
