2022-12-14qapi misc: Elide redundant has_FOO in generated CMarkus Armbruster1-2/+1
The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/misc.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

2022-12-01include/hw: VM state takes precedence in virtio_device_should_startAlex Bennée1-5/+18
The VM status should always preempt the device status for these checks. This ensures the device is in the correct state when we suspend the VM prior to migrations. This restores the checks to the order they where in before the refactoring moved things around. While we are at it lets improve our documentation of the various fields involved and document the two functions.

This avoids the circular close by deferring shutdown due to disconnection until a later point. virtio-user-blk already had this mechanism in place so generalise it as a vhost-user helper function and use for both blk and gpio devices.

2022-12-01vhost: enable vrings in vhost_dev_start() for vhost-user devicesStefano Garzarella1-2/+4
Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features") properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user backend, but we forgot to enable vrings as specified in docs/interop/vhost-user.rst: If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the ring starts directly in the enabled state. If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is initialized in a disabled state and is enabled by ``VHOST_USER_SET_VRING_ENABLE`` with parameter 1. Some vhost-user front-ends already did this by calling vhost_ops.vhost_set_vring_enable() directly: - backends/cryptodev-vhost.c - hw/net/virtio-net.c - hw/virtio/vhost-user-gpio.c But most didn't do that, so we would leave the vrings disabled and some backends would not work. We observed this issue with the rust version of virtiofsd [1], which uses the event loop [2] provided by the vhost-user-backend crate where requests are not processed if vring is not enabled. Let's fix this issue by enabling the vrings in vhost_dev_start() for vhost-user front-ends that don't already do this directly. Same thing also in vhost_dev_stop() where we disable vrings.

2022-11-21hw/sd: Fix sun4i allwinner-sdhost for U-BootStrahinja Jankovic1-0/+1
Trying to run U-Boot for Cubieboard (Allwinner A10) fails because it cannot access SD card. The problem is that FIFO register in current allwinner-sdhost implementation is at the address corresponding to Allwinner H3, but not A10. Linux kernel is not affected since Linux driver uses DMA access and does not use FIFO register for reading/writing. This patch adds new class parameter `is_sun4i` and based on that parameter uses register at offset 0x100 either as FIFO register (if sun4i) or as threshold register (if not sun4i; in this case register at 0x200 is FIFO register). Tested with U-Boot and Linux kernel image built for Cubieboard and OrangePi PC.

2022-11-21migration: Use non-atomic ops for clear log bitmapPeter Xu3-5/+10
Since we already have bitmap_mutex to protect either the dirty bitmap or the clear log bitmap, we don't need atomic operations to set/clear/test on the clear log bitmap. Switching all ops from atomic to non-atomic versions, meanwhile touch up the comments to show which lock is in charge. Introduced non-atomic version of bitmap_test_and_clear_atomic(), mostly the same as the atomic version but simplified a few places, e.g. dropped the "old_bits" variable, and also the explicit memory barriers.

2022-11-10block: Make bdrv_child_get_parent_aio_context I/OHanna Reitz3-3/+4
We want to use bdrv_child_get_parent_aio_context() from bdrv_parent_drained_{begin,end}_single(), both of which are "I/O or GS" functions. Prior to 3ed4f708fe1, all the implementations were I/O code anyway. 3ed4f708fe1 has put block jobs' AioContext field under the job mutex, so to make child_job_get_parent_aio_context() work in an I/O context, we need to take that lock there. Furthermore, blk_root_get_parent_aio_context() is not marked as anything, but is safe to run in an I/O context, so mark it that way now. (blk_get_aio_context() is an I/O code function.) With that done, all implementations explicitly are I/O code, so we can mark bdrv_child_get_parent_aio_context() as I/O code, too, so callers know it is safe to run from both GS and I/O contexts.

2022-11-07hw/virtio: introduce virtio_device_should_startAlex Bennée1-0/+18
The previous fix to virtio_device_started revealed a problem in its use by both the core and the device code. The core code should be able to handle the device "starting" while the VM isn't running to handle the restoration of migration state. To solve this duel use introduce a new helper for use by the vhost-user backends who all use it to feed a should_start variable. We can also pick up a change vhost_user_blk_set_status while we are at it which follows the same pattern.

2022-11-07intel-iommu: PASID supportJason Wang2-1/+8
This patch introduce ECAP_PASID via "x-pasid-mode". Based on the existing support for scalable mode, we need to implement the following missing parts: 1) tag VTDAddressSpace with PASID and support IOMMU/DMA translation with PASID 2) tag IOTLB with PASID 3) PASID cache and its flush 4) PASID based IOTLB invalidation For simplicity PASID cache is not implemented so we can simply implement the PASID cache flush as a no and leave it to be implemented in the future. For PASID based IOTLB invalidation, since we haven't had L1 stage support, the PASID based IOTLB invalidation is not implemented yet. For PASID based device IOTLB invalidation, it requires the support for vhost so we forbid enabling device IOTLB when PASID is enabled now. Those work could be done in the future. Note that though PASID based IOMMU translation is ready but no device can issue PASID DMA right now. In this case, PCI_NO_PASID is used as PASID to identify the address without PASID. vtd_find_add_as() has been extended to provision address space with PASID which could be utilized by the future extension of PCI core to allow device model to use PASID based DMA translation. This feature would be useful for: 1) prototyping PASID support for devices like virtio 2) future vPASID work 3) future PRS and vSVA work Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Message-Id: <20221028061436.30093-5-jasowang@redhat.com> Reviewed-by: Michael S.

2022-11-07intel-iommu: drop VTDBusJason Wang1-9/+2
We introduce VTDBus structure as an intermediate step for searching the address space. This works well with SID based matching/lookup. But when we want to support SID plus PASID based address space lookup, this intermediate steps turns out to be a burden. So the patch simply drops the VTDBus structure and use the PCIBus and devfn as the key for the g_hash_table(). This simplifies the codes and the future PASID extension. To prevent being slower for past vtd_find_as_from_bus_num() callers, a vtd_as cache indexed by the bus number is introduced to store the last recent search result of a vtd_as belongs to a specific bus.

2022-11-07msix: Assert that specified vector is in rangeAkihiko Odaki1-2/+2
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.

PCI devices support vq reset. Based on this function, the driver can adjust the size of the ring, and quickly recycle the buffer in the ring. The migration of the virtio devices will not happen during a reset operation. This is becuase the global iothread lock is held. Migration thread also needs the lock. As a result, when migration of virtio devices starts, the 'reset' status of VirtIOPCIQueue will always be 0. Thus, we do not need to add it in vmstate_virtio_pci_modern_queue_state.

2022-11-07hw/pci: PCIe Data Object Exchange emulationHuai-Cheng Kuo4-0/+131
Emulation of PCIe Data Object Exchange (DOE) PCIE Base Specification r6.0 6.3 Data Object Exchange Supports multiple DOE PCIe Extended Capabilities for a single PCIe device. For each capability, a static array of DOEProtocol should be passed to pcie_doe_init(). The protocols in that array will be registered under the DOE capability structure. 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. In pcie_doe_write_config(), the function will have no affect if the address is not within the related DOE PCIE extended capability.

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.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana1-5/+32
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.
