2017-09-29iothread: Make iothread_stop() idempotentEduardo Habkost
Currently, iothread_stop_all() makes all iothread objects unsafe to be destroyed, because qemu_thread_join() ends up being called twice. To fix this, make iothread_stop() idempotent by checking thread->stopped. Fixes the following crash: qemu-system-x86_64 -object iothread,id=iothread0 -monitor stdio -display none QEMU 2.10.50 monitor - type 'help' for more information (qemu) quit qemu: qemu_thread_join: No such process Aborted (core dumped) Reported-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <20170926130028.12471-1-ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-09-27migration: disable auto-converge during bulk block migrationPeter Lieven
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.

2017-09-27spapr: fix the value of SDR1 in kvmppc_put_books_sregs()Greg Kurz
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 Kurz
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.

2017-09-27ppc/kvm: generalize the use of kvmppc_get_htab_fd()Greg Kurz
The use of KVM_PPC_GET_HTAB_FD is open-coded in kvmppc_read_hptes() and kvmppc_write_hpte(). This patch modifies kvmppc_get_htab_fd() so that it can be used everywhere we need to access the in-kernel htab: - add an index argument => only kvmppc_read_hptes() passes an actual index, all other users pass 0 - add an errp argument to propagate error messages to the caller. => spapr migration code prints the error => hpte helpers pass &error_abort to keep the current behavior of hw_error() While here, this also fixes a bug in kvmppc_write_hpte() so that it opens the htab fd for writing instead of reading as it currently does. This never broke anything because we currently never call this code, as explained in the changelog of commit c1385933804bb: "This support updating htab managed by the hypervisor. Currently we don't have any user for this feature. This actually bring the store_hpte interface in-line with the load_hpte one. We may want to use this when we want to emulate henter hcall in qemu for HV kvm." The above is still true today.

2017-09-27ppc/kvm: change kvmppc_get_htab_fd() to return -errno on errorGreg Kurz

All savevm handlers expect to receive a negative errno on error. Let's patch kvmppc_get_htab_fd() accordingly. While here, let's change htab_load() in the spapr code to also propagate the error, since it doesn't make sense to abort() if we couldn't get the htab fd from KVM.

2017-09-27ppc/ide/macio: Add missing registersBenjamin Herrenschmidt
The timing register exists on all variants of MacIO IDE, we just store and return its value. The interrupts register only exists on KeyLargo but it doesn't hurt to have it. The lack of this register causes MacOS X to hangs under some circumstances. Both are 32-bit only. The HW might support smaller access sizes but no known OS uses them. Because the core IDE subsystem doesn't provide us with a way to query the main (level) interrupt state, nor do we have a way to know that DBDMA issued a (edge) interrupt, we reflect both through a private pair of qirq's in order to maintain the register state.

2017-09-27ppc/kvm: check some capabilities with kvm_vm_check_extension()Greg Kurz
The following capabilities are VM specific: - KVM_CAP_PPC_SMT_POSSIBLE - KVM_CAP_PPC_HTAB_FD - KVM_CAP_PPC_ALLOC_HTAB If both KVM HV and KVM PR are present, checking them always return the HV value, even if we explicitely requested to use PR. This has no visible effect for KVM_CAP_PPC_ALLOC_HTAB, because we also try the KVM_PPC_ALLOCATE_HTAB ioctl which is only suppored by HV. As a consequence, the spapr code doesn't even check KVM_CAP_PPC_HTAB_FD. However, this will cause kvmppc_hint_smt_possible(), introduced by commit fa98fbfcdfcb9, to report several VSMT modes (eg, Available VSMT modes: 8 4 2 1) whereas PR only support mode 1. This patch fixes all three anyway to use kvm_vm_check_extension(). It is okay since the VM is already created at the time kvm_arch_init() or kvmppc_reset_htab() is called.

2017-09-26block/qcow2-bitmap: fix use of uninitialized pointerVladimir Sementsov-Ogievskiy
Without initialization to zero dirty_bitmap field may be not zero for a bitmap which should not be stored and qcow2_store_persistent_dirty_bitmaps will erroneously call store_bitmap for it which leads to SIGSEGV on bdrv_dirty_bitmap_name.

2017-09-26qcow2: add shrink image supportPavel Butsykin
This patch add shrinking of the image file for qcow2. As a result, this allows us to reduce the virtual image size and free up space on the disk without copying the image. Image can be fragmented and shrink is done by punching holes in the image file.

2017-09-26qcow2: add qcow2_cache_discardPavel Butsykin
Whenever l2/refcount table clusters are discarded from the file we can automatically drop unnecessary content of the cache tables. This reduces the chance of eviction useful cache data and eliminates inconsistent data in the cache with the data in the file.

The flag is additional precaution against data loss. Perhaps in the future the operation shrink without this flag will be blocked for all formats, but for now we need to maintain compatibility with raw.
