2018-03-13migration: add postcopy migration of dirty bitmapsVladimir Sementsov-Ogievskiy
Postcopy migration of dirty bitmaps. Only named dirty bitmaps are migrated. If destination qemu is already containing a dirty bitmap with the same name as a migrated bitmap (for the same node), then, if their granularities are the same the migration will be done, otherwise the error will be generated. If destination qemu doesn't contain such bitmap it will be created.

2018-03-13vfio-pci: Allow mmap of MSIX BARAlexey Kardashevskiy
At the moment we unconditionally avoid mapping MSIX data of a BAR and emulate MSIX table in QEMU. However it is 1) not always necessary as a platform may provide a paravirt interface for MSIX configuration; 2) can affect the speed of MMIO access by emulating them in QEMU when frequently accessed registers share same system page with MSIX data, this is particularly a problem for systems with the page size bigger than 4KB. A new capability - VFIO_REGION_INFO_CAP_MSIX_MAPPABLE - has been added to the kernel [1] which tells the userspace that mapping of the MSIX data is possible now. This makes use of it so from now on QEMU tries mapping the entire BAR as a whole and emulate MSIX on top of that.

2018-03-13console: minimal hotplug suportGerd Hoffmann
This patch allows to unbind devices from QemuConsoles, using the new graphic_console_close() function. The QemuConsole will show a static display then, saying the device was unplugged. When re-plugging a display later on the QemuConsole will be reused. Eventually we will allocate and release QemuConsoles dynamically at some point in the future, that'll need more infrastructure though to notify user interfaces (gtk, sdl, spice, ...) about QemuConsoles coming and going.

2018-03-12membarrier: add --enable-membarrierPaolo Bonzini
Actually enable the global memory barriers if supported by the OS. Because only recent versions of Linux include the support, they are disabled by default. Note that it also has to be disabled for QEMU to run under Wine. Before this patch, rcutorture reports 85 ns/read for my machine, after the patch it reports 12.5 ns/read. On the other hand updates go from 50 *micro*seconds to 20 *milli*seconds. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2018-03-12membarrier: introduce qemu/sys_membarrier.hPaolo Bonzini
This new header file provides heavy-weight "global" memory barriers that enforce memory ordering on each running thread belonging to the current process. For now, use a dummy implementation that issues memory barriers on both sides (matching what QEMU has been doing so far). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
