This patch adds support for burst periods to the throttling code. With this feature the user can keep performing bursts as defined by the LeakyBucket.max rate for a configurable period of time.

We can currently initialize ThrottleConfig by zeroing all its fields, but this will change with the new fields to define the length of the burst periods. This patch introduces a new throttle_config_init() function and uses it to replace all memset() calls that initialize ThrottleConfig directly.

There's no need to keep throttle_conflicting(), throttle_is_valid() and throttle_max_is_missing_limit() as separate functions, so this patch merges all three into one. As a consequence, check_throttle_config() becomes redundant and can be replaced with throttle_is_valid().

When testing the ranges of valid values, set_cfg_value() creates sometimes invalid throttling configurations by setting bucket.max while leaving bucket.avg uninitialized. While this doesn't break the current tests, it will as soon as we unify all functions that check the validity of the throttling configuration. This patch ensures that the value of bucket.avg is valid when setting bucket.max.

The BDRV_O_INACTIVE flag should only be set for images explicitly opened by the user. snapshot=on needs to create a new qcow2 image and write some metadata to it. This is not a problem because it can't come from the source, so there's no reason to mark it as BDRV_O_INACTIVE, even though it is opened while waiting for the migration to complete. This fixes an assertion failure when -incoming and snapshot=on are combined. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The new feature for qcow2: storing bitmaps. This patch adds new header extension to qcow2 - Bitmaps Extension. It provides an ability to store virtual disk related bitmaps in a qcow2 image. For now there is only one type of such bitmaps: Dirty Tracking Bitmap, which just tracks virtual disk changes from some moment. Note: Only bitmaps, relative to the virtual disk, stored in qcow2 file, should be stored in this qcow2 file. The size of each bitmap (considering its granularity) is equal to virtual disk size.

This patch allows the instantiation of the vfio-amd-xgbe device from the QEMU command line (-device vfio-amd-xgbe,host="<device>"). The guest is exposed with a device tree node that combines the description of both XGBE and PHY (representation supported from 4.2 onwards kernel): Documentation/devicetree/bindings/net/amd-xgbe.txt. There are 5 register regions, 6 interrupts including 4 optional edge-sensitive per-channel interrupts. Some property values are inherited from host device tree. Host device tree must feature a combined XGBE/PHY representation (>= 4.2 host kernel). 2 clock nodes (dma and ptp) also are created. It is checked those clocks are fixed on host side. AMD XGBE node creation function has a dependency on vfio Linux header and more generally node creation function for VFIO platform devices only make sense with CONFIG_LINUX so let's protect this code with #ifdef CONFIG_LINUX.

Some passthrough'ed devices depend on clock nodes. Those need to be generated in the guest device tree. This patch introduces some helpers to build a clock node from information retrieved in the host device tree. - copy_properties_from_host copies properties from a host device tree node to a guest device tree node - fdt_build_clock_node builds a guest clock node and checks the host fellow clock is a fixed one. fdt_build_clock_node will become static as soon as it gets used. A dummy pre-declaration is needed for compilation of this patch.

This patch aligns the prototype with qemu_fdt_getprop. The caller can choose whether the function self-asserts on error (passing &error_fatal as Error ** argument, corresponding to the legacy behavior), or behaves differently such as simply output a message. In this later case the caller can use the new lenp parameter to interpret the error if any.

Current qemu_fdt_getprop exits if the property is not found. It is sometimes needed to read an optional property, in which case we do not wish to exit but simply returns a null value. This patch converts qemu_fdt_getprop to accept an Error **, and existing users are converted to pass &error_fatal. This preserves the existing behaviour. Then to use the API with your optional semantic a null parameter can be conveyed.
