Make's multiple output syntax x.c x.h: x.template gen < x.template actually invokes the command once for x.c and once for x.h (with differing $@ in each invocation). During a parallel build, the two commands may be invoked in parallel; this opens up a race, where the second invocation trashes a file supposedly produced during the first, and now in use by a dependent command. The various qapi code generators are susceptible to this; fix by making them generate just one file per invocation.

qemu-kvm passes numa/SRAT topology information for smp_cpus to SeaBIOS. However SeaBIOS always expects to setup max_cpus number of SRAT cpu entries (MaxCountCPUs variable in build_srat function of Seabios). When qemu-kvm runs with smp_cpus != max_cpus (e.g. -smp 2,maxcpus=4), Seabios will mistakenly use memory SRAT info for setting up CPU SRAT entries for the offline CPUs. Wrong SRAT memory entries are also created. This breaks NUMA in a guest. Fix by setting up SRAT info for max_cpus in qemu-kvm.

Limiting the number of in-flight requests is implemented very simply with a can_read callback. It does not require a semaphore, unlike the client side in block/nbd.c, because we can throttle directly the creation of coroutines. The client side can have a coroutine created at any time when an I/O request is made. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

由 Paolo Bonzini 提交于
Using coroutines enable asynchronous operation on both the network and the block side. Network can be owned by two coroutines at the same time, one writing and one reading. On the send side, mutual exclusion is guaranteed by a CoMutex. On the receive side, mutual exclusion is guaranteed because new coroutines immediately start receiving data, and no new coroutines are created as long as the previous one is receiving. Between receive and send, qemu-nbd can have an arbitrary number of in-flight block transfers. Throttling is implemented by the next patch. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

By attaching a client to an NBDRequest, we can avoid passing around the socket descriptor and data buffer. Also, we can now manage the reference count for the client in nbd_request_get/put request instead of having to do it ourselved in nbd_read. This simplifies things when coroutines are used.

This patch sets up the fd handler in nbd.c instead of qemu-nbd.c. It introduces NBDClient, which wraps the arguments to nbd_trip in a single structure, so that we can add a notifier to it. This way, qemu-nbd can know about disconnections. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>
