Add a board level property to the virt board which will enable EL2 on the CPU if the user asks for it. The default is not to provide EL2.

2017-01-20hw/arm/virt: Support using SMC for PSCIPeter Maydell
If we are giving the guest a CPU with EL2, it is likely to want to use the HVC instruction itself, for instance for providing PSCI to inner guest VMs. This makes using HVC as the PSCI conduit for the outer QEMU a bad idea. We will want to use SMC instead is this case: this makes sense because QEMU's PSCI implementation is effectively an emulation of functionality provided by EL3 firmware. Add code to support selecting the PSCI conduit to use, rather than hardcoding use of HVC. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.

The controller generates all the necessary commands to load (or store) data in memory. However, accesses are restricted to the segment window assigned the the flash module by the controller.

2017-01-19error: error_setg_errno(): errno gets preservedSascha Silbe
C11 allows errno to be clobbered by pretty much any library function call, so in general callers need to take care to save errno before calling other functions. However, for error reporting functions this is rather awkward and can make the code on the caller side more complicated than necessary. error_setg_errno() already takes care of preserving errno and some functions rely on that, so just promise that we continue to do so in the future.

2017-01-18fw-cfg: bump "x-file-slots" to 0x20 for 2.9+ machine typesLaszlo Ersek
More precisely, the "x-file-slots" count is bumped for all machine types that: (a) use fw_cfg, and (b) are not versioned (hence migration is not expected to work for them across QEMU releases anyway), or have version 2.9. This affects machine types implemented in the following source files: - "hw/arm/virt.c". The "virt-*" machine type is versioned, and the <= 2.8 versions already depend on HW_COMPAT_2_8 (see commit e353aac51b944). Therefore adding the "x-file-slots" compat values to HW_COMPAT_2_8 suffices. - "hw/i386/pc.c". The "pc-i440fx-*" (including "pc-*") and "pc-q35-*" machine types are versioned. Modifying HW_COMPAT_2_8 is sufficient here too (see commit "pc: Add 2.9 machine-types"). The "isapc" machtype is not versioned. The "xenfv" machine type, which uses fw_cfg for direct kernel booting, is also not versioned. - "hw/ppc/mac_newworld.c". The "mac99" machine type is not versioned. - "hw/ppc/mac_oldworld.c". The "g3beige" machine type is not versioned. - "hw/sparc/sun4m.c". None of the 9 machine types defined in this file appear versioned. - "hw/sparc64/sun4u.c". None of the 3 machine types defined in this file appear versioned. Cc: "Gabriel L. Somlo" <somlo@cmu.edu> Cc: "Michael S.

2017-01-18fw-cfg: turn FW_CFG_FILE_SLOTS into a device propertyLaszlo Ersek
We'd like to raise the value of FW_CFG_FILE_SLOTS. Doing it naively could lead to problems with backward migration: a more recent QEMU (running an older machine type) would allow the guest, in fw_cfg_select(), to select a high key value that is unavailable in the same machine type implemented by the older (target) QEMU. On the target host, fw_cfg_data_read() for example could dereference nonexistent entries. As first step, size the FWCfgState.entries[*] and FWCfgState.entry_order arrays dynamically. All three array sizes will be influenced by the new field FWCfgState.file_slots (and matching device property). Make the following changes: - Replace the FW_CFG_FILE_SLOTS macro with FW_CFG_FILE_SLOTS_MIN (minimum count of fw_cfg file slots) in the header file. The value remains 0x10. - Replace all uses of FW_CFG_FILE_SLOTS with a helper function called fw_cfg_file_slots(), returning the new property. - Eliminate the macro FW_CFG_MAX_ENTRY, and replace all its uses with a helper function called fw_cfg_max_entry(). - In the MMIO- and IO-mapped realize functions both, allocate all three arrays dynamically, based on the new property. - The new property defaults to FW_CFG_FILE_SLOTS_MIN. This is going to be customized in the following patches. Cc: "Gabriel L. Somlo" <somlo@cmu.edu> Cc: "Michael S.

2017-01-18vhost_net: device IOTLB supportJason Wang
This patches implements Device IOTLB support for vhost kernel. This is done through: 1) switch to use dma helpers when map/unmap vrings from vhost codes 2) introduce a set of VhostOps to: - setting up device IOTLB request callback - processing device IOTLB request - processing device IOTLB invalidation 2) kernel support for Device IOTLB API: - allow vhost-net to query the IOMMU IOTLB entry through eventfd - enable the ability for qemu to update a specified mapping of vhost - through ioctl. - enable the ability to invalidate a specified range of iova for the device IOTLB of vhost through ioctl. In x86/intel_iommu case this is triggered through iommu memory region notifier from device IOTLB invalidation descriptor processing routine. With all the above, kernel vhost_net can co-operate with userspace IOMMU. For vhost-user, the support could be easily done on top by implementing the VhostOps. Cc: Michael S.

This will make it possible to walk the list of bottom halves without holding the AioContext lock---and in turn to call bottom half handlers without holding the lock.

2017-01-16qemu-thread: introduce QemuLockCntPaolo Bonzini
A QemuLockCnt comprises a counter and a mutex, with primitives to increment and decrement the counter, and to take and release the mutex. It can be used to do lock-free visits to a data structure whenever mutexes would be too heavy-weight and the critical section is too long for RCU. This could be implemented simply by protecting the counter with the mutex, but QemuLockCnt is harder to misuse and more efficient.

2017-01-16block: get rid of bdrv_io_unplugged_begin/endPaolo Bonzini
bdrv_io_plug and bdrv_io_unplug are only called (via their BlockBackend equivalents) after starting asynchronous I/O. bdrv_drain is not going to be called while they are running, because---even if a coroutine runs for some reason---it will only drain in the next iteration of the event loop through bdrv_co_yield_to_drain. So this mechanism is unnecessary, get rid of it.

so it won't impose an additional limits on max_cpus limits supported by different targets. It removes global MAX_CPUMASK_BITS constant and need to bump it up whenever max_cpus is being increased for a target above MAX_CPUMASK_BITS value. Use runtime max_cpus value instead to allocate sufficiently sized node_cpu bitmasks in numa parser.

2017-01-12monitor: fix qmp/hmp query-memdev not reporting IDs of memory backendsIgor Mammedov
Considering 'id' is mandatory for user_creatable objects/backends and user_creatable_add_type() always has it as an argument regardless of where from it is called CLI/monitor or QMP, Fix issue by adding 'id' property to hostmem backends and set it in user_creatable_add_type() for every object that implements 'id' property. Then later at query-memdev time get 'id' from object directly.

2017-01-12monitor: reuse user_creatable_add_opts() instead of user_creatable_add()Igor Mammedov
Simplify code by dropping ~57LOC by merging user_creatable_add() into user_creatable_add_opts() and using the later from monitor. Along with it allocate opts_visitor_new() once in user_creatable_add_opts(). As result we have one less API func and a more readable/simple user_creatable_add_opts() vs user_creatable_add().
