2018-02-06vfio/pci: Add option to disable GeForce quirksAlex Williamson3-3/+9
These quirks are necessary for GeForce, but not for Quadro/GRID/Tesla assignment. Leaving them enabled is fully functional and provides the most compatibility, but due to the unique NVIDIA MSI ACK behavior[1], it also introduces latency in re-triggering the MSI interrupt. This overhead is typically negligible, but has been shown to adversely affect some (very) high interrupt rate applications. This adds the vfio-pci device option "x-no-geforce-quirks=" which can be set to "on" to disable this additional overhead. A follow-on optimization for GeForce might be to make use of an ioeventfd to allow KVM to trigger an irqfd in the kernel vfio-pci driver, avoiding the bounce through userspace to handle this device write. [1] Background: the NVIDIA driver has been observed to issue a write to the MMIO mirror of PCI config space in BAR0 in order to allow the MSI interrupt for the device to retrigger. Older reports indicated a write of 0xff to the (read-only) MSI capability ID register, while more recently a write of 0x0 is observed at config space offset 0x704, non-architected, extended config space of the device (BAR0 offset 0x88704). Virtualization of this range is only required for GeForce. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2018-02-06vfio/pci: Allow relocating MSI-X MMIOAlex Williamson3-1/+101
Recently proposed vfio-pci kernel changes (v4.16) remove the restriction preventing userspace from mmap'ing PCI BARs in areas overlapping the MSI-X vector table. This change is primarily intended to benefit host platforms which make use of system page sizes larger than the PCI spec recommendation for alignment of MSI-X data structures (ie. not x86_64). In the case of POWER systems, the SPAPR spec requires the VM to program MSI-X using hypercalls, rendering the MSI-X vector table unused in the VM view of the device. However, ARM64 platforms also support 64KB pages and rely on QEMU emulation of MSI-X. Regardless of the kernel driver allowing mmaps overlapping the MSI-X vector table, emulation of the MSI-X vector table also prevents direct mapping of device MMIO spaces overlapping this page. Thanks to the fact that PCI devices have a standard self discovery mechanism, we can try to resolve this by relocating the MSI-X data structures, either by creating a new PCI BAR or extending an existing BAR and updating the MSI-X capability for the new location. There's even a very slim chance that this could benefit devices which do not adhere to the PCI spec alignment guidelines on x86_64 systems. This new x-msix-relocation option accepts the following choices: off: Disable MSI-X relocation, use native device config (default) auto: Use a known good combination for the platform/device (none yet) bar0..bar5: Specify the target BAR for MSI-X data structures If compatible, the target BAR will either be created or extended and the new portion will be used for MSI-X emulation. The first obvious user question with this option is how to determine whether a given platform and device might benefit from this option. In most cases, the answer is that it won't, especially on x86_64. Devices often dedicate an entire BAR to MSI-X and therefore no performance sensitive registers overlap the MSI-X area. Take for example: # lspci -vvvs 0a:00.0 0a:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection ... Region 0: Memory at db680000 (32-bit, non-prefetchable) [size=512K] Region 3: Memory at db7f8000 (32-bit, non-prefetchable) [size=16K] ... Capabilities: [70] MSI-X: Enable+ Count=10 Masked- Vector table: BAR=3 offset=00000000 PBA: BAR=3 offset=00002000 This device uses the 16K bar3 for MSI-X with the vector table at offset zero and the pending bits arrary at offset 8K, fully honoring the PCI spec alignment guidance. The data sheet specifically refers to this as an MSI-X BAR. This device would not see a benefit from MSI-X relocation regardless of the platform, regardless of the page size. However, here's another example: # lspci -vvvs 02:00.0 02:00.0 Serial Attached SCSI controller: xxxxxxxx ... Region 0: I/O ports at c000 [size=256] Region 1: Memory at ef640000 (64-bit, non-prefetchable) [size=64K] Region 3: Memory at ef600000 (64-bit, non-prefetchable) [size=256K] ... Capabilities: [c0] MSI-X: Enable+ Count=16 Masked- Vector table: BAR=1 offset=0000e000 PBA: BAR=1 offset=0000f000 Here the MSI-X data structures are placed on separate 4K pages at the end of a 64KB BAR. If our host page size is 4K, we're likely fine, but at 64KB page size, MSI-X emulation at that location prevents the entire BAR from being directly mapped into the VM address space. Overlapping performance sensitive registers then starts to be a very likely scenario on such a platform. At this point, the user could enable tracing on vfio_region_read and vfio_region_write to determine more conclusively if device accesses are being trapped through QEMU. Upon finding a device and platform in need of MSI-X relocation, the next problem is how to choose target PCI BAR to host the MSI-X data structures. A few key rules to keep in mind for this selection include: * There are only 6 BAR slots, bar0..bar5 * 64-bit BARs occupy two BAR slots, 'lspci -vvv' lists the first slot * PCI BARs are always a power of 2 in size, extending == doubling * The maximum size of a 32-bit BAR is 2GB * MSI-X data structures must reside in an MMIO BAR Using these rules, we can evaluate each BAR of the second example device above as follows: bar0: I/O port BAR, incompatible with MSI-X tables bar1: BAR could be extended, incurring another 64KB of MMIO bar2: Unavailable, bar1 is 64-bit, this register is used by bar1 bar3: BAR could be extended, incurring another 256KB of MMIO bar4: Unavailable, bar3 is 64bit, this register is used by bar3 bar5: Available, empty BAR, minimum additional MMIO A secondary optimization we might wish to make in relocating MSI-X is to minimize the additional MMIO required for the device, therefore we might test the available choices in order of preference as bar5, bar1, and finally bar3. The original proposal for this feature included an 'auto' option which would choose bar5 in this case, but various drivers have been found that make assumptions about the properties of the "first" BAR or the size of BARs such that there appears to be no foolproof automatic selection available, requiring known good combinations to be sourced from users. This patch is pre-enabled for an 'auto' selection making use of a validated lookup table, but no entries are yet identified.

The kernel provides similar emulation of PCI BAR register access to QEMU, so up until now we've used that for things like BAR sizing and storing the BAR address. However, if we intend to resize BARs or add BARs that don't exist on the physical device, we need to switch to the pure QEMU emulation of the BAR.

2018-02-06vfio/pci: Add base BAR MemoryRegionAlex Williamson2-25/+72
Add one more layer to our stack of MemoryRegions, this base region allows us to register BARs independently of the vfio region or to extend the size of BARs which do map to a region. This will be useful when we want hypervisor defined BARs or sections of BARs, for purposes such as relocating MSI-X emulation. We therefore call msix_init() based on this new base MemoryRegion, while the quirks, which only modify regions still operate on those sub-MemoryRegions.

In order to enable TCE operations support in KVM, we have to inform the KVM about VFIO groups being attached to specific LIOBNs; the necessary bits are implemented already by IOMMU MR and VFIO. This defines get_attr() for the SPAPR TCE IOMMU MR which makes VFIO call the KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE ioctl and establish LIOBN-to-IOMMU link. This changes spapr_tce_set_need_vfio() to avoid TCE table reallocation if the kernel supports the TCE acceleration.

2018-02-06vfio/spapr: Use iommu memory region's get_attr()Alexey Kardashevskiy2-0/+28
In order to enable TCE operations support in KVM, we have to inform the KVM about VFIO groups being attached to specific LIOBNs. The KVM already knows about VFIO groups, the only bit missing is which in-kernel TCE table (the one with user visible TCEs) should update the attached broups. There is an KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE attribute of the VFIO KVM device which receives a groupfd/tablefd couple. This uses a new memory_region_iommu_get_attr() helper to get the IOMMU fd and calls KVM to establish the link. As get_attr() is not implemented yet, this should cause no behavioural change.

2018-02-06migration: incoming postcopy advise sanity checksGreg Kurz1-3/+18
If postcopy-ram was set on the source but not on the destination, migration doesn't occur, the destination prints an error and boots the guest: qemu-system-ppc64: Expected vmdescription section, but got 0 We end up with two running instances. This behaviour was introduced in 2.11 by commit 58110f0acb1a "migration: split common postcopy out of ram postcopy" to prepare ground for the upcoming dirty bitmap postcopy support. It adds a new case where the source may send an empty postcopy advise because dirty bitmap doesn't need to check page sizes like RAM postcopy does. If the source has enabled postcopy-ram, then it sends an advise with the page size values. If the destination hasn't enabled postcopy-ram, then loadvm_postcopy_handle_advise() leaves the page size values on the stream and returns. This confuses qemu_loadvm_state() later on and causes the destination to start execution. As discussed several times, postcopy-ram should be enabled both sides to be functional. This patch changes the destination to perform some extra checks on the advise length to ensure this is the case. Otherwise an error is returned and migration is aborted.

2018-02-06migration: Recover block devices if failure in device stateDr. David Alan Gilbert1-1/+2
In e91d895 I added the new pause-before-switchover mechanism to allow migration completion to be delayed; this changes the last state prior to completion to MIGRATE_STATUS_DEVICE rather than MIGRATE_STATUS_ACTIVE. Fix the failure path in migration_completion to recover the block devices if it fails in MIGRATE_STATUS_DEVICE, not just the MIGRATE_STATUS_ACTIVE that it previously had. This corresponds to rh bz: https://bugzilla.redhat.com/show_bug.cgi?id=1538494 whose symptom is an occasional source crash on a failed migration.

2018-02-06migration/savevm.c: set MAX_VM_CMD_PACKAGED_SIZE to 1ul << 32Daniel Henrique Barboza1-1/+1
MAX_VM_CMD_PACKAGED_SIZE is a constant used in qemu_savevm_send_packaged and loadvm_handle_cmd_packaged to determine whether a package is too big to be sent or received. qemu_savevm_send_packaged is called inside postcopy_start (migration/migration.c) to send the MigrationState in a single blob to the destination, using the MIG_CMD_PACKAGED subcommand, which will read it up using loadvm_handle_cmd_packaged. If the blob is larger than MAX_VM_CMD_PACKAGED_SIZE, an error is thrown and the postcopy migration is aborted. Both MAX_VM_CMD_PACKAGED_SIZE and MIG_CMD_PACKAGED were introduced by commit 11cf1d984b ("MIG_CMD_PACKAGED: Send a packaged chunk ..."). The constant has its original value of 1ul << 24 (16MB). The current MAX_VM_CMD_PACKAGED_SIZE value is not enough to support postcopy migration of bigger pseries guests. The blob size for a postcopy migration of a pseries guest with the following setup: qemu-system-ppc64 --nographic -vga none -machine pseries,accel=kvm -m 64G \ -smp 1,maxcpus=32 -device virtio-blk-pci,drive=rootdisk \ -drive file=f27.qcow2,if=none,cache=none,format=qcow2,id=rootdisk \ -netdev user,id=u1 -net nic,netdev=u1 Goes around 12MB. Bumping the RAM to 128G makes the blob sizes goes to 20MB. With 256G the blob goes to 37MB - more than twice the current maximum size. At this moment the pseries machine can handle guests with up to 1TB of RAM, making this postcopy blob goes to 128MB of size approximately. Following the discussions made in [1], there is a need to understand what devices are aggressively consuming the blob in that manner and see if that can be mitigated. Until then, we can set MAX_VM_CMD_PACKAGED_SIZE to the maximum value allowed. Since the size is a 32 bit int variable, we can set it as 1ul << 32, giving a maximum blob size of 4G that is enough to support postcopy migration of 32TB RAM guests given the above constraints.

2018-02-05travis: improve python version test coverageDaniel P. Berrange1-5/+9
Currently travis declares ancient python 2.4 is desired. Update that to 2.6 which is the oldest version any targetted distros still needs. If we just list a python 3 version at the top level this will double the number of travis jobs we run which is unreasonable. So arbitrarily pick the clang test matrix entries to build with python 3.0 and 3.6, to extend coverage of python versions, without increasing job count or build time. Signed-off-by: Daniel P.

2018-02-05qemu.py: don't launch again before shutdown()Amador Pahim1-0/+8
If a VM is launched, files are created and a cleanup is required before a new launch. This cleanup is executed by shutdown(), so shutdown() must be called even if the VM is manually terminated (i.e. using kill). This patch creates a control to make sure launch() will not be executed again if shutdown() is not called after the previous launch().

The 'returncode' Popen attribute is not guaranteed to be updated. It actually depends on a call to either poll(), wait() or communicate(). On the other hand, poll() will: "Check if child process has terminated. Set and return returncode attribute." Let's use the poll() to check whether the process is running and to get the updated process exit code, when the process is finished.
