2018-02-13hw/pci-bridge: fix pcie root port's IO hints capabilityMarcel Apfelbaum
The gen_pcie_root_port mem-reserve and pref32-reserve properties are defined as size (so uint64_t), but passed as uint32_t when building the 'IO hints' vendor specific capability. Passing 4G (or more) gets truncated and passed as a zero reservation. Is not a huge issue since the guest firmware will always compare the hints with the default value and take the maximum. Fix it by passing the values as uint64_t and failing to init the gen_pcie_root_port id invalid values are used. Signed-off-by: Marcel Apfelbaum <marcel@redhat.com> Reviewed-by: Michael S.

2018-02-11misc: introduce new mos6522 VIA device and enable it for ppc buildsMark Cave-Ayland
The MOS6522 VIA forms the bridge part of several Mac devices, including the Mac via-cuda and via-pmu devices. Introduce a standard mos6522 device that can be shared amongst multiple implementations. This is effectively taking the 6522 parts out of cuda.c and turning them into a separate device whilst also applying some style tidy-ups and including a conversion to trace-events.

2018-02-09block: Simplify bdrv_can_write_zeroes_with_unmap()Eric Blake
We don't need the can_write_zeroes_with_unmap field in BlockDriverInfo, because it is redundant information with supported_zero_flags & BDRV_REQ_MAY_UNMAP. Note that BlockDriverInfo and supported_zero_flags are both per-device settings, rather than global state about the driver as a whole, which means one or both of these bits of information can already be conditional. Let's audit how they were set: crypto: always setting can_write_ to false is pointless (the struct starts life zero-initialized), no use of supported_ nbd: just recently fixed to set can_write_ if supported_ includes MAY_UNMAP (thus this commit effectively reverts bca80059e and solves the problem mentioned there in a more global way) file-posix, iscsi, qcow2: can_write_ is conditional, while supported_ was unconditional; but passing MAY_UNMAP would fail with ENOTSUP if the condition wasn't met qed: can_write_ is unconditional, but pwrite_zeroes lacks support for MAY_UNMAP and supported_ is not set. Perhaps support can be added later (since it would be similar to qcow2), but for now claiming false is no real loss all other drivers: can_write_ is not set, and supported_ is either unset or a passthrough Simplify the code by moving the conditional into supported_zero_flags for all drivers, then dropping the now-unused BDI field. For callers that relied on bdrv_can_write_zeroes_with_unmap(), we return the same per-device settings for drivers that had conditions (no observable change in behavior there); and can now return true (instead of false) for drivers that support passthrough (for example, the commit driver) which gives those drivers the same fix as nbd just got in bca80059e. For callers that relied on supported_zero_flags, we now have a few more places that can avoid a wasted call to pwrite_zeroes() that will just fail with ENOTSUP.

2018-02-09qdict qlist: Make most helper macros functionsMarkus Armbruster
The macro expansions of qdict_put_TYPE() and qlist_append_TYPE() need qbool.h, qnull.h, qnum.h and qstring.h to compile. We include qnull.h and qnum.h in the headers, but not qbool.h and qstring.h. Works, because we include those wherever the macros get used. Open-coding these helpers is of dubious value. Turn them into functions and drop the includes from the headers.

2018-02-09Use #include "..." for our own headers, <...> for othersMarkus Armbruster
System headers should be included with <...>, our own headers with "...". Offenders tracked down with an ugly, brittle and probably buggy Perl script. Previous iteration was commit a9c94277f0. Delete inclusions of "string.h" and "strings.h" instead of fixing them to <string.h> and <strings.h>, because we always include these via osdep.h. Put the cleaned up system header includes first. While there, separate #include from file comment with exactly one blank line.

2018-02-08pci: removed the is_express field since a uniform interface was insertedYoni Bettan
according to Eduardo Habkost's commit fd3b02c889 all PCIEs now implement INTERFACE_PCIE_DEVICE so we don't need is_express field anymore. Devices that implements only INTERFACE_PCIE_DEVICE (is_express == 1) or devices that implements only INTERFACE_CONVENTIONAL_PCI_DEVICE (is_express == 0) where not affected by the change. The only devices that were affected are those that are hybrid and also had (is_express == 1) - therefor only: - hw/vfio/pci.c - hw/usb/hcd-xhci.c - hw/xen/xen_pt.c For those 3 I made sure that QEMU_PCI_CAP_EXPRESS is on in instance_init() Reviewed-by: Marcel Apfelbaum <marcel@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Yoni Bettan <ybettan@redhat.com> Reviewed-by: Michael S.

2018-02-08pci/bus: let it has higher migration priorityPeter Xu
In the past, we prioritized IOMMU migration so that we have such a priority order: IOMMU > PCI Devices When migrating a guest with both vIOMMU and a pcie-root-port, we'll always migrate vIOMMU first, since pci buses will be seen to have the same priority of general PCI devices. That's problematic. The thing is that PCI bus number information is stored in the root port, and that is needed by vIOMMU during post_load(), e.g., to figure out context entry for a device. If we don't have correct bus numbers for devices, we won't be able to recover device state of the DMAR memory regions, and things will be messed up. So let's boost the PCIe root ports to be even with higher priority: PCIe Root Port > IOMMU > PCI Devices A smoke test shows that this patch fixes bug 1538953. Also, apply this rule to all the PCI bus/bridge devices: ioh3420, xio3130_downstream, xio3130_upstream, pcie_pci_bridge, pci-pci bridge, i82801b11. I noted that we set pcie_pci_bridge_dev_vmstate twice. Clean that up together. CC: Alex Williamson <alex.williamson@redhat.com> CC: Marcel Apfelbaum <marcel@redhat.com> CC: Michael S.

2018-02-08vhost: Build temporary section list and deref after commitDr. David Alan Gilbert
Igor spotted that there's a race, where a region that's unref'd in a _del callback might be free'd before the set_mem_table call in the _commit callback, and thus the vhost might end up using free memory. Fix this by building a complete temporary sections list, ref'ing every section (during add and nop) and then unref'ing the whole list right at the end of commit.

2018-02-08coroutine-lock: make qemu_co_enter_next thread-safePaolo Bonzini
qemu_co_queue_next does not need to release and re-acquire the mutex, because the queued coroutine does not run immediately. However, this does not hold for qemu_co_enter_next. Now that qemu_co_queue_wait can synchronize (via QemuLockable) with code that is not running in coroutine context, it's important that code using qemu_co_enter_next can easily use a standardized locking idiom. First of all, qemu_co_enter_next must use aio_co_wake to restart the coroutine. Second, the function gains a second argument, a QemuLockable*, and the comments of qemu_co_queue_next and qemu_co_queue_restart_all are adjusted to clarify the difference.

2018-02-08coroutine-lock: convert CoQueue to use QemuLockablePaolo Bonzini
There are cases in which a queued coroutine must be restarted from non-coroutine context (with qemu_co_enter_next). In this cases, qemu_co_enter_next also needs to be thread-safe, but it cannot use a CoMutex and so cannot qemu_co_queue_wait. Use QemuLockable so that the CoQueue can interchangeably use CoMutex or QemuMutex.

2018-02-08lockable: add QemuLockablePaolo Bonzini
QemuLockable is a polymorphic lock type that takes an object and knows which function to use for locking and unlocking. The implementation could use C11 _Generic, but since the support is not very widespread I am instead using __builtin_choose_expr and __builtin_types_compatible_p, which are already used by include/qemu/atomic.h. QemuLockable can be used to implement lock guards, or to pass around a lock in such a way that a function can release it and re-acquire it. The next patch will do this for CoQueue.
