Functions to serialize / deserialize(restore) HBitmap. HBitmap should be saved to linear sequence of bits independently of endianness and bitmap array element (unsigned long) size. Therefore Little Endian is chosen. These functions are appropriate for dirty bitmap migration, restoring the bitmap in several steps is available. To save performance, every step writes only the last level of the bitmap. All other levels are restored by hbitmap_deserialize_finish() as a last step of restoring. So, HBitmap is inconsistent while restoring.

HBitmap is an implementation detail of block dirty bitmap that should be hidden from users. Introduce a BdrvDirtyBitmapIter to encapsulate the underlying HBitmapIter. A small difference in the interface is, before, an HBitmapIter is initialized in place, now the new BdrvDirtyBitmapIter must be dynamically allocated because the structure definition is in block/dirty-bitmap.c.

2016-10-24iotests: Do not rely on unavailable domains in 162Max Reitz2-5/+16
There are some (mostly ISP-specific) name servers who will redirect non-existing domains to special hosts. In this case, we will get a different error message when trying to connect to such a host, which breaks test 162. 162 needed this specific error message so it can confirm that qemu was indeed trying to connect to the user-specified port. However, we can also confirm this by setting up a local NBD server on exactly that port; so we can fix the issue by doing just that.

2016-10-24qemu-iotests: Test I/O in a single drive from a throttling groupAlberto Garcia2-7/+30
iotest 093 contains a test that creates a throttling group with several drives and performs I/O in all of them. This patch adds a new test that creates a similar setup but only performs I/O in one of the drives at the same time. This is useful to test that the round robin algorithm is behaving properly in these scenarios, and is specifically written using the regression introduced in 27ccdd52598290f0f8b58be56e as an example.

In 27ccdd52598290f0f8b58be56e235aff7aebfaf3 the throttling fields were moved from BlockDriverState to BlockBackend. However in a few cases the code started using throttling fields from the active BlockBackend instead of the round-robin token, making the algorithm behave incorrectly. This can cause starvation if there's a throttling group with several drives but only one of them has I/O.

2016-10-24i2c: Fix SMBus read transactions to avoid double eventsCorey Minyard1-13/+19
Change 2293c27faddf (i2c: implement broadcast write) added broadcast capability to the I2C bus, but it broke SMBus read transactions. An SMBus read transaction does two i2c_start_transaction() calls without an intervening i2c_end_transfer() call. This will result in i2c_start_transfer() adding the same device to the current_devs list twice, and then the ->event() for the same device gets called twice in the second call to i2c_start_transfer(), resulting in the smbus code getting confused. Note that this happens even with pure I2C devices when simulating SMBus over I2C. This fix only scans the bus if the current set of devices is empty. This means that the current set of devices stays fixed until i2c_end_transfer() is called, which is really what you want. This also deletes the empty check from the top of i2c_end_transfer(). It's unnecessary, and it prevents the broadcast variable from being set to false at the end of the transaction if no devices were on the bus.

2016-10-24arm_mptimer: Convert to use ptimerDmitry Osipenko2-71/+83
Current ARM MPTimer implementation uses QEMUTimer for the actual timer, this implementation isn't complete and mostly tries to duplicate of what generic ptimer is already doing fine. Conversion to ptimer brings the following benefits and fixes: - Simple timer pausing implementation - Fixes counter value preservation after stopping the timer - Properly handles prescaler != 0 / counter = 0 / load = 0 cases - Code simplification and reduction Bump VMSD to version 3, since VMState is changed and is not compatible with the previous implementation.

2016-10-24tests: ptimer: Replace 10000 with 1Dmitry Osipenko1-28/+28
The 10000 is an arbitrarily chosen value used for advancing the QEMU time, so that ptimer's now != last. Change it to 1 to make code a bit more readable.

2016-10-24hw/ptimer: Add "no counter round down" policyDmitry Osipenko2-0/+13
For most of the timers counter starts to decrement after first period expires. Due to rounding down performed by the ptimer_get_count, it returns counter - 1 for the running timer, so that for the ptimer user it looks like counter gets decremented immediately after running the timer. Add "no counter round down" policy that provides correct behaviour for those timers.
