This defines new QOM object - IOMMUMemoryRegion - with MemoryRegion as a parent. This moves IOMMU-related fields from MR to IOMMU MR. However to avoid dymanic QOM casting in fast path (address_space_translate, etc), this adds an @is_iommu boolean flag to MR and provides new helper to do simple cast to IOMMU MR - memory_region_get_iommu. The flag is set in the instance init callback. This defines memory_region_is_iommu as memory_region_get_iommu()!=NULL. This switches MemoryRegion to IOMMUMemoryRegion in most places except the ones where MemoryRegion may be an alias.

2017-07-10vfio: Test realized when using VFIOGroup.device_list iteratorAlex Williamson
VFIOGroup.device_list is effectively our reference tracking mechanism such that we can teardown a group when all of the device references are removed. However, we also use this list from our machine reset handler for processing resets that affect multiple devices. Generally device removals are fully processed (exitfn + finalize) when this reset handler is invoked, however if the removal is triggered via another reset handler (piix4_reset->acpi_pcihp_reset) then the device exitfn may run, but not finalize. In this case we hit asserts when we start trying to access PCI helpers since much of the PCI state of the device is released. To resolve this, add a pointer to the Object DeviceState in our common base-device and skip non-realized devices as we iterate. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

This patch enables the virtio-net tx queue size to be configurable between 256 (the default queue size) and 1024 by the user when the vhost-user backend is used. Currently, the maximum tx queue size for other backends is 512 due to the following limitations: - QEMU backend: the QEMU backend implementation in some cases may send 1024+1 iovs to writev. - Vhost_net backend: there are possibilities that the guest sends a vring_desc of memory which crosses a MemoryRegion thereby generating more than 1024 iovs after translation from guest-physical address in the backend.

Factor a check for this, and also for valid indicator state values into rtas_set_allocation_state().

2017-06-30spapr: Eliminate DRC 'signalled' state variableDavid Gibson
The 'signalled' field in the DRC appears to be entirely a torturous workaround for the fact that PCI devices were started in UNISOLATED state for unclear reasons. 1) 'signalled' is already meaningless for logical (so far, all non PCI) DRCs. It's always set to true (at least at any point it might be tested), and can't be assigned any real meaning due to the way signalling works for logical DRCs. 2) For PCI DRCs, the only time signalled would be false is when non-zero functions of a multifunction device are hotplugged, followed by function zero (the other way around is explicitly not permitted). In that case the secondary function DRCs are attached, but the notification isn't sent to the guest until function 0 is plugged. 3) signalled being false is used to allow a DRC detach to switch mode back to ISOLATED state, which allows a secondary function to be hotplugged then unplugged with function 0 never inserted. Without this a secondary function starting in UNISOLATED state couldn't be detached again without function 0 being inserted, all the functions configured by the guest, then sent back to ISOLATED state. 4) But now that PCI DRCs start in ISOLATED state, there's nothing to be done. If the guest doesn't get the notification, it won't switch the device to UNISOLATED state, so nothing prevents it from being unplugged. If the guest does move it to UNISOLATED state without the signal (due to a manual drmgr call, for instance) then it really isn't safe to unplug it. So, this patch removes the signalled variable and all code related to it.

2017-06-30spapr: fix migration of ICPState objects from/to older QEMUGreg Kurz
Commit 5bc8d26de20c ("spapr: allocate the ICPState object from under sPAPRCPUCore") moved ICPState objects from the machine to CPU cores. This is an improvement since we no longer allocate ICPState objects that will never be used. But it has the side-effect of breaking migration of older machine types from older QEMU versions. This patch allows spapr to register dummy "icp/server" entries to vmstate. These entries use a dedicated VMStateDescription that can swallow and discard state of an incoming migration stream, and that don't send anything on outgoing migration. As for real ICPState objects, the instance_id is the cpu_index of the corresponding vCPU, which happens to be equal to the generated instance_id of older machine types. The machine can unregister/register these entries when CPUs are dynamically plugged/unplugged. This is only available for pseries-2.9 and older machines, thanks to a compat property.

2017-06-30pseries: Move CPU compatibility property to machineDavid Gibson
Server class POWER CPUs have a "compat" property, which is used to set the backwards compatibility mode for the processor. However, this only makes sense for machine types which don't give the guest access to hypervisor privilege - otherwise the compatibility level is under the guest's control. To reflect this, this removes the CPU 'compat' property and instead creates a 'max-cpu-compat' property on the pseries machine. Strictly speaking this breaks compatibility, but AFAIK the 'compat' option was never (directly) used with -device or device_add. The option was used with -cpu. So, to maintain compatibility, this patch adds a hack to the cpu option parsing to strip out any compat options supplied with -cpu and set them on the machine property instead of the now deprecated cpu property.

2017-06-28machine: export register_compat_prop()Peter Xu
We have HW_COMPAT_*, however that's only bound to machines, not other things (like accelerators). Behind it, it was register_compat_prop() that played the trick. Let's export the function for further use outside HW_COMPAT_* magic. Meanwhile, move it to qdev-properties.c where seems more proper (since it'll be used not only in machine codes).

2017-06-16q35/mch: implement extended TSEG sizesLaszlo Ersek
The q35 machine type currently lets the guest firmware select a 1MB, 2MB or 8MB TSEG (basically, SMRAM) size. In edk2/OVMF, we use 8MB, but even that is not enough when a lot of VCPUs (more than approx. 224) are configured -- SMRAM footprint scales largely proportionally with VCPU count. Introduce a new property for "mch" called "extended-tseg-mbytes", which expresses (in megabytes) the user's choice of TSEG (SMRAM) size. Invent a new, QEMU-specific register in the config space of the DRAM Controller, at offset 0x50, in order to allow guest firmware to query the TSEG (SMRAM) size. According to Intel Document Number 316966-002, Table 5-1 "DRAM Controller Register Address Map (D0:F0)": Warning: Address locations that are not listed are considered Intel Reserved registers locations. Reads to Reserved registers may return non-zero values. Writes to reserved locations may cause system failures. All registers that are defined in the PCI 2.3 specification, but are not necessary or implemented in this component are simply not included in this document. The reserved/unimplemented space in the PCI configuration header space is not documented as such in this summary. Offsets 0x50 and 0x51 are not listed in Table 5-1. They are also not part of the standard PCI config space header. And they precede the capability list as well, which starts at 0xe0 for this device. When the guest writes value 0xffff to this register, the value that can be read back is that of "mch.extended-tseg-mbytes" -- unless it remains 0xffff. The guest is required to write 0xffff first (as opposed to a read-only register) because PCI config space is generally not cleared on QEMU reset, and after S3 resume or reboot, new guest firmware running on old QEMU could read a guest OS-injected value from this register. After reading the available "extended" TSEG size, the guest firmware may actually request that TSEG size by writing pattern 11b to the ESMRAMC register's TSEG_SZ bit-field. (The Intel spec referenced above defines only patterns 00b (1MB), 01b (2MB) and 10b (8MB); 11b is reserved.) On the QEMU command line, the value can be set with -global mch.extended-tseg-mbytes=N The default value for 2.10+ q35 machine types is 16. The value is limited to 0xfff (4095) at the moment, purely so that the product (4095 MB) can be stored to the uint32_t variable "tseg_size" in mch_update_smram(). Users are responsible for choosing sensible TSEG sizes. On 2.9 and earlier q35 machine types, the default value is 0. This lets the 11b bit pattern in ESMRAMC.TSEG_SZ, and the register at offset 0x50, keep their original behavior. When "extended-tseg-mbytes" is nonzero, the new register at offset 0x50 is set to that value on reset, for completeness. PCI config space is migrated automatically, so no VMSD changes are necessary.
