2022-11-07msix: Assert that specified vector is in rangeAkihiko Odaki
There were several different ways to deal with the situation where the vector specified for a msix function is out of bound: - early return a function and keep progresssing - propagate the error to the caller - mark msix unusable - assert it is in bound - just ignore An out-of-bound vector should not be specified if the device implementation is correct so let msix functions always assert that the specified vector is in range. An exceptional case is virtio-pci, which allows the guest to configure vectors. For virtio-pci, it is more appropriate to introduce its own checks because it is sometimes too late to check the vector range in msix functions.

2022-11-07acpi: pc/35: sanitize _GPE declaration orderIgor Mammedov
Move _GPE block declaration before it gets referenced by other hotplug handlers. While at it move PCI hotplug (_E01) handler after PCI tree description to avoid forward reference to to not yet declared methods/devices. PS: Forward 'usage' usualy is fine as long as it's hidden within method, however 'iasl' may print warnings. So be nice to iasl/guest OS and do things in proper order. PS2: Also follow up patches will move some of hotplug code from PCI tree to _E01 and that also requires PCI Device nodes build first, before Scope can reuse that from global context.

2022-11-07acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ↵Igor Mammedov
ennumeration generate AML PCI-ISA bridges that are built in PIIX/Q35 are building its own AML using AcpiDevAmlIf interface. Now build_append_pci_bus_devices() gained AcpiDevAmlIf interface support to get AML of devices atached to PCI slots. So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge() and let PCI bus enumeration to include PCI-ISA bridge AML when it's enumerated by build_append_pci_bus_devices(). AML change is mostly contextual, which moves whole ISA hierarchy directly under PCI host bridge instead of it being described as separate \SB.PCI0.ISA block. Note: If bus/slot that hosts ISA bridge has BSEL set, it will gain new ASUN and _DMS entries (i.e. acpi-index support, but it should not cause any functional change and that is fine from PCI Firmware spec point of view), potentially it's possible to suppress that by adding a flag to PCIDevice but I don't see a reason to do that yet, I'd rather treat bridge just as any other PCI device if it's possible.

2022-11-07acpi: pc: vga: use AcpiDevAmlIf interface to build VGA device descriptorsIgor Mammedov
NB: We do not expect any functional change in any ACPI tables with this change. It's only a refactoring. NB2: Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them. However, modules are reused between all architectures so CONFIG_ACPI is on. For those architectures, dummy stub function definitions help to resolve symbols. This change uses more of these and so it adds a couple of dummy stub definitions so that symbols for those can be resolved.

2022-11-07vhost-user: Fix out of order vring host notification handlingYajun Wu
vhost backend sends host notification for every VQ. If backend creates VQs in parallel, the VHOST_USER_SLAVE_VRING_HOST_NOTIFIER_MSG may arrive to QEMU in different order than incremental queue index order. For example VQ 1's message arrive earlier than VQ 0's: After alloc VhostUserHostNotifier for VQ 1. GPtrArray becomes [ nil, VQ1 pointer ] After alloc VhostUserHostNotifier for VQ 0. GPtrArray becomes [ VQ0 pointer, nil, VQ1 pointer ] This is wrong. fetch_notifier will return NULL for VQ 1 in vhost_user_get_vring_base, causes host notifier miss removal(leak). The fix is to remove current element from GPtrArray, make the right position for element to insert.

2022-11-07hw/virtio/virtio-iommu-pci: Enforce the device is plugged on the root busEric Auger
In theory the virtio-iommu-pci could be plugged anywhere in the PCIe topology and as long as the dt/acpi info are properly built this should work. However at the moment we fail to do that because the virtio-iommu-pci BDF is not computed at plug time and in that case vms->virtio_iommu_bdf gets an incorrect value. For instance if the virtio-iommu-pci is plugged onto a pcie root port and the virtio-iommu protects a virtio-block-pci device the guest does not boot. So let's do not pretend we do support this case and fail the initialize() if we detect the virtio-iommu-pci is plugged anywhere else than on the root bus. Anyway this ability is not needed.

For each protocol, vendor ID, type, and corresponding callback function (handle_request()) should be implemented. This callback function represents how the DOE request for corresponding protocol will be handled. pcie_doe_{read/write}_config() must be appended to corresponding PCI device's config_read/write() handler to enable DOE access. In pcie_doe_read_config(), false will be returned if pci_config_read() offset is not within DOE capability range.

2022-11-06s390x/cpu topology: add max_threads machine class attributePierre Morel
The S390 CPU topology accepts the smp.threads argument while in reality it does not effectively allow multthreading. Let's keep this behavior for machines older than 7.2 and refuse to use threads in newer machines until multithreading is really exposed to the guest by the machine.

Currently, when running 'qemu-system-s390x -M s390-ccw-virtio,help' the s390x-specific properties are not listed anymore. This happens because since commit d8fb7d0969 ("vl: switch -M parsing to keyval") the properties have to be defined at the class level and not at the instance level anymore.

2022-11-06s390x/pci: RPCIT second pass when mappings exhaustedMatthew Rosato
If we encounter a new mapping while the number of available DMA entries in vfio is 0, we are currently skipping that mapping which is a problem if we manage to free up DMA space after that within the same RPCIT -- we will return to the guest with CC0 and have not mapped everything within the specified range. This issue was uncovered while testing changes to the s390 linux kernel iommu/dma code, where a different usage pattern was employed (new mappings start at the end of the aperture and work back towards the front, making us far more likely to encounter new mappings before invalidated mappings during a global refresh). Fix this by tracking whether any mappings were skipped due to vfio DMA limit hitting 0; when this occurs, we still continue the range and unmap/map anything we can - then we must re-run the range again to pickup anything that was missed. This must occur in a loop until all requests are satisfied (success) or we detect that we are still unable to complete all mappings (return ZPCI_RPCIT_ST_INSUFF_RES).

2022-11-06s390x/css: revert SCSW ctrl/flag bits on errorPeter Jin
Revert the control and flag bits in the subchannel status word in case the SSCH operation fails with non-zero CC (ditto for CSCH and HSCH). According to POPS, the control and flag bits are only changed if SSCH, CSCH, and HSCH return CC 0, and no other action should be taken otherwise. In order to simulate that after the fact, the bits need to be reverted on non-zero CC. While the do_subchannel_work logic for virtual (virtio) devices will return condition code 0, passthrough (vfio) devices may encounter errors from either the host kernel or real hardware that need to be accounted for after this point. This includes restoring the state of the Subchannel Status Word to reflect the subchannel, as these bits would not be set in the event of a non-zero condition code from the affected instructions. Experimentation has shown that a failure on a START SUBCHANNEL (SSCH) to a passthrough device would leave the subchannel with the START PENDING activity control bit set, thus blocking subsequent SSCH operations in css_do_ssch() until some form of error recovery was undertaken since no interrupt would be expected.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana
improve error handling during module load, by changing: bool module_load(const char *prefix, const char *lib_name); void module_load_qom(const char *type); to: int module_load(const char *prefix, const char *name, Error **errp); int module_load_qom(const char *type, Error **errp); where the return value is: -1 on module load error, and errp is set with the error 0 on module or one of its dependencies are not installed 1 on module load success 2 on module load success (module already loaded or built-in) module_load_qom_one has been introduced in: commit 28457744c345 ("module: qom module support"), which built on top of module_load_one, but discarded the bool return value. Restore it. Adapt all callers to emit errors, or ignore them, or fail hard, as appropriate in each context. Replace the previous emission of errors via fprintf in _some_ error conditions with Error and error_report, so as to emit to the appropriate target. A memory leak is also fixed as part of the module_load changes. audio: when attempting to load an audio module, report module load errors. Note that still for some callers, a single issue may generate multiple error reports, and this could be improved further. Regarding the audio code itself, audio_add() seems to ignore errors, and this should probably be improved. block: when attempting to load a block module, report module load errors. For the code paths that already use the Error API, take advantage of those to report module load errors into the Error parameter. For the other code paths, we currently emit the error, but this could be improved further by adding Error parameters to all possible code paths. console: when attempting to load a display module, report module load errors. qdev: when creating a new qdev Device object (DeviceState), report load errors. If a module cannot be loaded to create that device, now abort execution (if no CONFIG_MODULE) or exit (if CONFIG_MODULE). qom/object.c: when initializing a QOM object, or looking up class_by_name, report module load errors. qtest: when processing the "module_load" qtest command, report errors in the load of the module.

2022-11-04hw/arm/boot: Set SME and SVE EL3 vector lengths when booting kernelPeter Maydell
When we direct boot a kernel on a CPU which emulates EL3, we need to set up the EL3 system registers as the Linux kernel documentation specifies: https://www.kernel.org/doc/Documentation/arm64/booting.rst For SVE and SME this includes: - ZCR_EL3.LEN must be initialised to the same value for all CPUs the kernel is executed on. - SMCR_EL3.LEN must be initialised to the same value for all CPUs the kernel will execute on. Although we are technically compliant with this, the "same value" we currently use by default is the reset value of 0. This will end up forcing the guest kernel's SVE and SME vector length to be only the smallest supported length. Initialize the vector length fields to their maximum possible value, which is 0xf. If the implementation doesn't actually support that vector length then the effective vector length will be constrained down to the maximum supported value at point of use. This allows the guest to use all the vector lengths the emulated CPU supports (by programming the _EL2 and _EL1 versions of these registers.)
