2017-10-03iothread: delay the context release to finalizePeter Xu1-2/+4
When gcontext is used with iothread, the context will be destroyed during iothread_stop(). That's not good since sometimes we would like to keep the resources until iothread is destroyed, but we may want to stop the thread before that point. Delay the destruction of gcontext to iothread finalize. Then we can do: iothread_stop(thread); some_cleanup_on_resources(); iothread_destroy(thread); We may need this patch if we want to run chardev IOs in iothreads and hopefully clean them up correctly. For more specific information, please see 2b316774f6 ("qemu-char: do not operate on sources from finalize callbacks").

2017-10-03iothread: export iothread_stop()Peter Xu2-8/+17
So that internal iothread users can explicitly stop one iothread without destroying it. Since at it, fix iothread_stop() to allow it to be called multiple times. Before this patch we may call iothread_stop() more than once on single iothread, while that may not be correct since qemu_thread_join() is not allowed to run twice. From manual of pthread_join(): Joining with a thread that has previously been joined results in undefined behavior.

2017-10-03iothread: provide helpers for internal usePeter Xu2-0/+24
IOThread is a general framework that contains IO loop environment and a real thread behind. It's also good to be used internally inside qemu. Provide some helpers for it to create iothreads to be used internally. Put all the internal used iothreads into the internal object container.

2017-10-02kvm: check KVM_CAP_NR_VCPUS with kvm_vm_check_extension()Greg Kurz1-21/+22
On a modern server-class ppc host with the following CPU topology: Architecture: ppc64le Byte Order: Little Endian CPU(s): 32 On-line CPU(s) list: 0,8,16,24 Off-line CPU(s) list: 1-7,9-15,17-23,25-31 Thread(s) per core: 1 If both KVM PR and KVM HV loaded and we pass: -machine pseries,accel=kvm,kvm-type=PR -smp 8 We expect QEMU to warn that this exceeds the number of online CPUs: Warning: Number of SMP cpus requested (8) exceeds the recommended cpus supported by KVM (4) Warning: Number of hotpluggable cpus requested (8) exceeds the recommended cpus supported by KVM (4) but nothing is printed... This happens because on ppc the KVM_CAP_NR_VCPUS capability is VM specific ndreally depends on the KVM type, but we currently use it as a global capability. And KVM returns a fallback value based on KVM HV being present. Maybe KVM on POWER shouldn't presume anything as long as it doesn't have a VM, but in all cases, we should call KVM_CREATE_VM first and use KVM_CAP_NR_VCPUS as a VM capability. This patch hence changes kvm_recommended_vcpus() accordingly and moves the sanity checking of smp_cpus after the VM creation. It is okay for the other archs that also implement KVM_CAP_NR_VCPUS, ie, mips, s390, x86 and arm, because they don't depend on the VM being created or not.

2017-10-02kvm: check KVM_CAP_SYNC_MMU with kvm_vm_check_extension()Greg Kurz3-6/+8
On a server-class ppc host, this capability depends on the KVM type, ie, HV or PR. If both KVM are present in the kernel, we will always get the HV specific value, even if we explicitely requested PR on the command line. This can have an impact if we're using hugepages or a balloon device. Since we've already created the VM at the time any user calls kvm_has_sync_mmu(), switching to kvm_vm_check_extension() is enough to fix any potential issue. It is okay for the other archs that also implement KVM_CAP_SYNC_MMU, ie, mips, s390, x86 and arm, because they don't depend on the VM being created or not. While here, let's cache the state of this extension in a bool variable, since it has several users in the code, as suggested by Thomas Huth.

2017-09-27migration: pre_save return intDr. David Alan Gilbert59-70/+199
Modify the pre_save method on VMStateDescription to return an int rather than void so that it potentially can fail. Changed zillions of devices to make them return 0; the only case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already had an error_report/return case. Note: If you add an error exit in your pre_save you must emit an error_report to say why.

2017-09-27migration: disable auto-converge during bulk block migrationPeter Lieven3-1/+17
auto-converge and block migration currently do not play well together. During block migration the auto-converge logic detects that ram migration makes no progress and thus throttles down the vm until it nearly stalls completely. Avoid this by disabling the throttling logic during the bulk phase of the block migration.

2017-09-27mac_dbdma: remove unused IO fields from DBDMAStateMark Cave-Ayland2-6/+0
These fields were used to manually handle IO requests that weren't aligned to a sector boundary before this feature was supported by the block API. Once the block API changed to support byte-aligned IO requests, the macio controller was switched over to use it in commit be1e343 but these fields were accidentally left behind.

2017-09-27spapr: fix the value of SDR1 in kvmppc_put_books_sregs()Greg Kurz6-58/+56
When running with KVM PR, if a new HPT is allocated we need to inform KVM about the HPT address and size. This is currently done by hacking the value of SDR1 and pushing it to KVM in several places. Also, migration breaks the guest since it is very unlikely the HPT has the same address in source and destination, but we push the incoming value of SDR1 to KVM anyway. This patch introduces a new virtual hypervisor hook so that the spapr code can provide the correct value of SDR1 to be pushed to KVM each time kvmppc_put_books_sregs() is called. It allows to get rid of all the hacking in the spapr/kvmppc code and it fixes migration of nested KVM PR.

2017-09-27spapr_pci: make index property mandatoryGreg Kurz1-54/+8
PHBs can be created with an index property, in which case the machine code automatically sets all the MMIO windows at addresses derived from the index. Alternatively, they can be manually created without index, but the user has to provide addresses for all MMIO windows. The non-index way happens to be more trouble than it's worth: it's difficult to use, keeps requiring (potentially incompatible) changes when some new parameter needs adding, and is awkward to check for collisions. It currently even has a bug that prevents to use two non-index PHBs because their child DRCs are all derived from the same index == -1 value, and, thus, collide. This patch hence makes the index property mandatory. As a consequence, the PHB's memory regions and BUID are now always configured according to the index, and it is no longer possible to set them from the command line. This DOES BREAK backwards compat, but we don't think the non-index PHB feature was used in practice (at least libvirt doesn't) and the simplification is worth it.
