2017-01-10curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)Stefan Weil1-0/+3
For builds with Mingw-w64 as it is included in Cygwin, there are two header files which define KEY_EVENT with different values. This results in lots of compiler warnings like this one: CC vl.o In file included from /qemu/include/ui/console.h:340:0, from /qemu/vl.c:76: /usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined #define KEY_EVENT 0633 /* We were interrupted by an event */ In file included from /usr/share/mingw-w64/include/windows.h:74:0, from /usr/share/mingw-w64/include/winsock2.h:23, from /qemu/include/sysemu/os-win32.h:29, from /qemu/include/qemu/osdep.h:100, from /qemu/vl.c:24: /usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition #define KEY_EVENT 0x1 QEMU only uses the KEY_EVENT macro from wincon.h. Therefore we can undefine the macro coming from curses.h. The explicit include statement for curses.h in ui/curses.c is not needed and was removed. Those two modifications fix the redefinition warnings.

2017-01-10memhp: don't generate memory hotplug AML if it's not enabled/supportedIgor Mammedov2-3/+1
That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

2017-01-10virtio: convert to use DMA apiJason Wang3-13/+28
Currently, all virtio devices bypass IOMMU completely. This is because address_space_memory is assumed and used during DMA emulation. This patch converts the virtio core API to use DMA API. This idea is - introducing a new transport specific helper to query the dma address space. (only pci version is implemented). - query and use this address space during virtio device guest memory accessing when iommu platform (VIRTIO_F_IOMMU_PLATFORM) was enabled for this device.

2017-01-10intel_iommu: allow migrationPeter Xu1-0/+1

2017-01-10migration: allow to prioritize save state entriesPeter Xu1-0/+6
During migration, save state entries are saved/loaded without a specific order - we just traverse the savevm_state.handlers list and do it one by one. This might not be enough. There are requirements that we need to load specific device's vmstate first before others. For example, VT-d IOMMU contains DMA address remapping information, which is required by all the PCI devices to do address translations. We need to make sure IOMMU's device state is loaded before the rest of the PCI devices, so that DMA address translation can work properly. This patch provide a VMStateDescription.priority value to allow specify the priority of the saved states. The loadvm operation will be done with those devices with higher vmsd priority. Before this patch, we are possibly achieving the ordering requirement by an assumption that the ordering will be the same with the ordering that objects are created. A better way is to mark it out explicitly in the VMStateDescription table, like what this patch does. Current ordering logic is still naive and slow, but after all that's not a critical path so IMO it's a workable solution for now. Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S.

2017-01-09i2c: Allow I2C devices to NAK start eventsCorey Minyard1-4/+12
Add a return value to the event handler. Some I2C devices will NAK if they have no data, so allow them to do this. This required the following changes: Go through all the event handlers and change them to return int and return 0. Modify i2c_start_transfer to terminate the transaction on a NAK. Modify smbus handing to not assert if a NAK occurs on a second operation, and terminate the transaction and return -1 instead. Add some information on semantics to I2CSlaveClass.

2017-01-06record/replay: add network supportPavel Dovgalyuk1-0/+12
This patch adds support of recording and replaying network packets in irount rr mode. Record and replay for network interactions is performed with the network filter. Each backend must have its own instance of the replay filter as follows: -netdev user,id=net1 -device rtl8139,netdev=net1 -object filter-replay,id=replay,netdev=net1 Replay network filter is used to record and replay network packets. While recording the virtual machine this filter puts all packets coming from the outer world into the log. In replay mode packets from the log are injected into the network device. All interactions with network backend in replay mode are disabled. v5 changes: - using iov_to_buf function instead of loop Signed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru> Signed-off-by: Jason Wang <jasowang@redhat.com>

2017-01-03aio: self-tune polling timeStefan Hajnoczi1-2/+8
This patch is based on the algorithm for the kvm.ko halt_poll_ns parameter in Linux. The initial polling time is zero. If the event loop is woken up within the maximum polling time it means polling could be effective, so grow polling time. If the event loop is woken up beyond the maximum polling time it means polling is not effective, so shrink polling time. If the event loop makes progress within the current polling time then the sweet spot has been reached. This algorithm adjusts the polling time so it can adapt to variations in workloads. The goal is to reach the sweet spot while also recognizing when polling would hurt more than help. Two new trace events, poll_grow and poll_shrink, are added for observing polling time adjustment.

2017-01-03aio: add .io_poll_begin/end() callbacksStefan Hajnoczi1-0/+20
The begin and end callbacks can be used to prepare for the polling loop and clean up when polling stops. Note that they may only be called once for multiple aio_poll() calls if polling continues to succeed. Once polling fails the end callback is invoked before aio_poll() resumes file descriptor monitoring.
