2016-11-01nvdimm acpi: introduce _FITXiao Guangrong
_FIT is required for hotplug support, guest will inquire the updated device info from it if a hotplug event is received As FIT buffer is not completely mapped into guest address space, so a new function, Read FIT whose UUID is UUID 648B9CF2-CDA1-4312-8AD9-49C4AF32BD62, handle 0x10000, function index is 0x1, is reserved by QEMU to read the piece of FIT buffer. The buffer is concatenated before _FIT return Refer to docs/specs/acpi-nvdimm.txt for detailed design Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2016-10-24block: Remove "options" indirection from blockdev-addKevin Wolf
Now that QAPI supports boxed types, we can have unions at the top level of a command, so let's put our real options directly there for blockdev-add instead of having a single "options" dict that contains the real arguments. blockdev-add is still experimental and we already made substantial changes to the API recently, so we're free to make changes like this one, too.

2016-10-24atomic: base mb_read/mb_set on load-acquire and store-releasePaolo Bonzini
This introduces load-acquire and store-release operations in QEMU. For now, just use them as an implementation detail of atomic_mb_read and atomic_mb_set. Since docs/atomics.txt documents that atomic_mb_read only synchronizes with an atomic_mb_set of the same variable, we can use the new implementation everywhere instead of seq-cst loads and stores.

2016-10-07block: Add qdev ID to DEVICE_TRAY_MOVEDKevin Wolf
The event currently only contains the BlockBackend name. However, with anonymous BlockBackends, this is always the empty string. Add the qdev ID (or if none was given, the QOM path) so that the user can still see which device caused the event. Event generation has to be moved from bdrv_eject() to the BlockBackend because the BDS doesn't know the attached device, but that's easy because blk_eject() is the only user of it.

2016-09-27cpus-common: lock-free fast path for cpu_exec_start/endPaolo Bonzini
Set cpu->running without taking the cpu_list lock, only requiring it if there is a concurrent exclusive section. This requires adding a new field to CPUState, which records whether a running CPU is being counted in pending_cpus. When an exclusive section is started concurrently with cpu_exec_start, cpu_exec_start can use the new field to determine if it has to wait for the end of the exclusive section. Likewise, cpu_exec_end can use it to see if start_exclusive is waiting for that CPU. This a separate patch for easier bisection of issues. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-09-27cpus-common: simplify locking for start_exclusive/end_exclusivePaolo Bonzini
It is not necessary to hold qemu_cpu_list_mutex throughout the exclusive section, because no other exclusive section can run while pending_cpus != 0. exclusive_idle() is called in cpu_exec_start(), and that prevents any CPUs created after start_exclusive() from entering cpu_exec() during an exclusive section.

2016-09-27cpus-common: remove redundant call to exclusive_idle()Paolo Bonzini
No need to call exclusive_idle() from cpu_exec_end since it is done immediately afterwards in cpu_exec_start. Any exclusive section could run as soon as cpu_exec_end leaves, because cpu->running is false and the mutex is not taken, so the call does not add any protection either.

2016-08-10vhost-user: Introduce a new protocol feature REPLY_ACK.Prerna Saxena
This introduces the VHOST_USER_PROTOCOL_F_REPLY_ACK. If negotiated, client applications should send a u64 payload in response to any message that contains the "need_reply" bit set on the message flags. Setting the payload to "zero" indicates the command finished successfully. Likewise, setting it to "non-zero" indicates an error. Currently implemented only for SET_MEM_TABLE.

2016-07-19qapi: Implement boxed types for commands/eventsEric Blake
Turn on the ability to pass command and event arguments in a single boxed parameter, which must name a non-empty type (although the type can be a struct with all optional members). For structs, it makes it possible to pass a single qapi type instead of a breakout of all struct members (useful if the arguments are already in a struct or if the number of members is large); for other complex types, it is now possible to use a union or alternate as the data for a command or event. The empty type may be technically feasible if needed down the road, but it's easier to forbid it now and relax things to allow it later, than it is to allow it now and have to special case how the generated 'q_empty' type is handled (see commit 7ce106a9 for reasons why nothing is generated for the empty type). An alternate type is never considered empty, but now that a boxed type can be either an object or an alternate, we have to provide a trivial QAPISchemaAlternateType.is_empty(). The new call to arg_type.is_empty() during QAPISchemaCommand.check() requires that we first check the type in question; but there is no chance of introducing a cycle since objects do not refer back to commands. We still have a split in syntax checking between ad-hoc parsing up front (merely validates that 'boxed' has a sane value) and during .check() methods (if 'boxed' is set, then 'data' must name a non-empty user-defined type). Generated code is unchanged, as long as no client uses the new feature.

2016-07-06qapi: Add new visit_complete() functionEric Blake
Making each output visitor provide its own output collection function was the only remaining reason for exposing visitor sub-types to the rest of the code base. Add a polymorphic visit_complete() function which is a no-op for input visitors, and which populates an opaque pointer for output visitors. For maximum type-safety, also add a parameter to the output visitor constructors with a type-correct version of the output pointer, and assert that the two uses match. This approach was considered superior to either passing the output parameter only during construction (action at a distance during visit_free() feels awkward) or only during visit_complete() (defeating type safety makes it easier to use incorrectly). Most callers were function-local, and therefore a mechanical conversion; the testsuite was a bit trickier, but the previous cleanup patch minimized the churn here. The visit_complete() function may be called at most once; doing so lets us use transfer semantics rather than duplication or ref-count semantics to get the just-built output back to the caller, even though it means our behavior is not idempotent.
