* KVM: do not use sigtimedwait to catch SIGBUSPaolo Bonzini2017-03-038-44/+53
| | | | | | | | Call kvm_on_sigbus_vcpu asynchronously from the VCPU thread. Information for the SIGBUS can be stored in thread-local variables and processed later in kvm_cpu_exec. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* KVM: remove kvm_arch_on_sigbusPaolo Bonzini2017-03-037-58/+13Star
| | | | | | | | Build it on kvm_arch_on_sigbus_vcpu instead. They do the same for "action optional" SIGBUSes, and the main thread should never get "action required" SIGBUSes because it blocks the signal. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* cpus: remove ugly cast on sigbus_handlerPaolo Bonzini2017-03-036-56/+65
| | | | | | | | | | | The cast is there because sigbus_handler is invoked via sigfd_handler. But it feels just wrong to use struct qemu_signalfd_siginfo in the prototype of a function that is passed to sigaction. Instead, do a simple-minded conversion of qemu_signalfd_siginfo to siginfo_t.

| * cpu-exec: remove unnecessary check of cpu->exit_requestPaolo Bonzini2017-02-241-4/+0Star
| | | | | | | | | | | | | | | | | | The cpu->exit_request check in cpu_loop_exec_tb is unnecessary, because cpu->tcg_exit_req is always set after cpu->exit_request. So let the TB exit and we will pick up the exit request later in cpu_handle_interrupt. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
| * replay: check icount in cpu exec loopPavel Dovgalyuk2017-02-241-8/+7Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds check to break cpu loop when icount expires without setting the TB_EXIT_ICOUNT_EXPIRED flag. It happens when there is no available translated blocks and all instructions were executed. In icount replay mode unnecessary tb_find will be called (which may cause an exception) and execution will be non-deterministic. Because cpu_loop_exec_tb cannot longjmp anymore, we can remove the anticipated call to align_clocks in cpu_loop_exec_tb, as well as the SyncClocks *sc argument.

The former TB_EXIT_REQUESTED and TB_EXIT_ICOUNT_EXPIRED cases are unified, since we can distinguish them from the value of the interrupt flag. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

This may not work when IOMMU is enabled: dma_as(bus_master_as) were initialized in pcibus_machine_done() after virtio_realize(). This will cause a segfault. Fixing this by using pci_device_iommu_address_space() instead to make sure address space were initialized at this time. With this fix, IOMMU device were required to be initialized before any virtio-pci devices.

The virtio_load() process is a little tricky because vring addresses are serialized in two separate places. VIRTIO 1.0 devices serialize desc and then a subsection with used and avail. Legacy devices only serialize desc. Live migration of VIRTIO 1.0 devices fails on the destination host with: VQ 0 size 0x80 < last_avail_idx 0x12f8 - used_idx 0x0 Failed to load virtio-blk:virtio error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk' This happens because the memory region cache is only initialized after desc is loaded and not after the used and avail subsection is loaded. If the guest chose memory addresses that don't match the legacy ring layout then the wrong guest memory location is accessed. Wait until all ring addresses are known before trying to initialize the region cache. Also clarify the incomplete comment about VIRTIO-1 ring address subsection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switching to vring caches exposed an existing bug in virtio_queue_set_notification(): We can't access vring structures if they have not been set up yet. This may happen, for example, for virtio-blk devices with multiple queues: The code will try to switch notifiers for every queue, but the guest may have only set up a subset of them. Fix this by guarding access to the vring memory by checking for vring.desc. The first aio poll will iron out any remaining inconsistencies for later-configured queues (buggy legacy drivers).

This simplifies a lot of the parsing as well, as we can treat everything a bit simpler since nonexistent options are simply NULL pointers instead of empty strings. An important item to note: Ceph has many extra option values that can be specified as key/value pairs. This was handled previously in the driver by extracting the values that the QEMU driver cared about, and then blindly passing all extra options to rbd after splitting them into key/value pairs, and cleaning up any special character escaping. The practice is continued in this patch; there is an option "keyvalue-pairs" that is populated with all the key/value pairs that the QEMU driver does not care about. These key/value pairs will override any settings in the 'conf' configuration file, just as they did before. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Jeff Cody <jcody@redhat.com>

The function qemu_rbd_next_tok() searched for various key/value pairs, and copied them into buffers. This will soon be an unnecessary extra step, so we will now return found strings by reference only, and offload the responsibility for safely handling/coping these strings to the caller. This also cleans up error handling some, as the callers now rely on the Error object to determine if there is a parse error.

To avoid the hang and get at least some audio playback up and running (it's a little bit crackling, but better than nothing), we can use the SDL locking functions SDL_LockAudio() and SDL_UnlockAudio() to sync with the sound playback thread instead.

It does not change expiration time if the timer is already set. This patch is needed to make this timer deterministic and to use execution record/replay for audio devices. audio_reset_timer is used in the function audio_vm_change_state_handler. Therefore every time VM is stopped or restarted the timer will be reset to new timeout. Virtual clock does not proceed while VM is stopped. Therefore there is no need in resetting the timeout when VM restarts. v2: updated commit message v3: now using timer_mod_anticipate function (as suggested by Yurii Zubrytskyi) Signed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru> Message-id: 20170214071510.6112.76764.stgit@PASHA-ISP Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
