2016-03-11nvdimm acpi: initialize the resource used by NVDIMM ACPIXiao Guangrong
32 bits IO port starting from 0x0a18 in guest is reserved for NVDIMM ACPI emulation. The table, NVDIMM_DSM_MEM_FILE, will be patched into NVDIMM ACPI binary code OSPM uses this port to tell QEMU the final address of the DSM memory and notify QEMU to emulate the DSM method Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2016-03-11i386: populate floppy drive information in DSDTRoman Kagan
On x86-based systems Linux determines the presence and the type of floppy drives via a query of a CMOS field. So does SeaBIOS when populating the return data for int 0x13 function 0x08. However Windows doesn't do it. Instead, it requests this information from BIOS via int 0x13/0x08 or through ACPI objects _FDE (Floppy Drive Enumerate) and _FDI (Floppy Drive Information) of the floppy controller object. On UEFI systems only ACPI-based detection is supported. QEMU doesn't provide those objects in its ACPI tables and as a result floppy drives are invisible to Windows on UEFI/OVMF. This patch adds those objects to the floppy controller in DSDT, populating them with the information from respective QEMU objects.

2016-03-11balloon: fix segfault and harden the stats queueLadi Prosek
The segfault here is triggered by the driver notifying the stats queue twice after adding a buffer to it. This effectively resets stats_vq_elem back to NULL and QEMU crashes on the next stats timer tick in balloon_stats_poll_cb. This is a regression introduced in 51b19ebe4320f3dc, although admittedly the device assumed too much about the stats queue protocol even before that commit. This commit adds a few more checks and ensures that the one stats buffer gets deallocated on device reset.

For platform supports AVX2 instructions, use AVX2 instructions for optimization can help to improve the performance of buffer_find_nonzero_offset() about 30% comparing to SSE2. Live migration can be faster with this optimization, the test result shows that for an 8GiB RAM idle guest just boots, this patch can help to shorten the total live migration time about 6%.

2016-03-08input: linux evdev supportGerd Hoffmann
This patch adds support for reading input events directly from linux evdev devices and forward them to the guest. Unlike virtio-input-host which simply passes on all events to the guest without looking at them this will interpret the events and feed them into the qemu input subsystem. Therefore this is limited to what the qemu input subsystem and the emulated input devices are able to handle. Also there is no support for absolute coordinates (tablet/touchscreen). So we are talking here about basic mouse and keyboard support. The advantage is that it'll work without virtio-input drivers in the guest, the events are delivered to the usual ps/2 or usb input devices (depending on what the machine happens to have). And for keyboards qemu is able to switch the keyboard between guest and host on hotkey. The hotkey is hard-coded for now (both control keys), initialy the guest owns the keyboard. Probably most useful when assigning vga devices with vfio and using a physical monitor instead of vnc/spice/gtk as guest display. Usage: Add '-input-linux /dev/input/event<nr>' to the qemu command line. Note that udev has rules which populate /dev/input/by-{id,path} with static names, which might be more convinient to use.

2016-03-08filter-buffer: Add status_changed callback processingzhanghailiang
While the status of filter-buffer changing from 'on' to 'off', it need to release all the buffered packets, and delete the related timer, while switch from 'off' to 'on', it need to resume the release packets timer. Here, we extract the process of setup timer into a new helper, which will be used in the new status_changed callback.

2016-03-08filter: Add 'status' property for filter objectzhanghailiang
With this property, users can control if this filter is 'on' or 'off'. The default behavior for filter is 'on'. For some types of filters, they may need to react to status changing, So here, we introduced status changing callback/notifier for filter class. We will skip the disabled ('off') filter when delivering packets in net layer.
