2023-05-10aio-wait: avoid AioContext lock in aio_wait_bh_oneshot()Stefan Hajnoczi
There is no need for the AioContext lock in aio_wait_bh_oneshot(). It's easy to remove the lock from existing callers and then switch from AIO_WAIT_WHILE() to AIO_WAIT_WHILE_UNLOCKED() in aio_wait_bh_oneshot(). Document that the AioContext lock should not be held across aio_wait_bh_oneshot(). Holding a lock across aio_poll() can cause deadlock so we don't want callers to do that. This is a step towards getting rid of the AioContext lock.

2023-05-09vfio/pci: Static Resizable BAR capabilityAlex Williamson
The PCI Resizable BAR (ReBAR) capability is currently hidden from the VM because the protocol for interacting with the capability does not support a mechanism for the device to reject an advertised supported BAR size. However, when assigned to a VM, the act of resizing the BAR requires adjustment of host resources for the device, which absolutely can fail. Linux does not currently allow us to reserve resources for the device independent of the current usage. The only writable field within the ReBAR capability is the BAR Size register. The PCIe spec indicates that when written, the device should immediately begin to operate with the provided BAR size. The spec however also notes that software must only write values corresponding to supported sizes as indicated in the capability and control registers. Writing unsupported sizes produces undefined results. Therefore, if the hypervisor were to virtualize the capability and control registers such that the current size is the only indicated available size, then a write of anything other than the current size falls into the category of undefined behavior, where we can essentially expose the modified ReBAR capability as read-only. This may seem pointless, but users have reported that virtualizing the capability in this way not only allows guest software to expose related features as available (even if only cosmetic), but in some scenarios can resolve guest driver issues. Additionally, no regressions in behavior have been reported for this change. A caveat here is that the PCIe spec requires for compatibility that devices report support for a size in the range of 1MB to 512GB, therefore if the current BAR size falls outside that range we revert to hiding the capability.

2023-05-09vfio/migration: Skip log_sync during migration SETUP stateAvihai Horon
Currently, VFIO log_sync can be issued while migration is in SETUP state. However, doing this log_sync is at best redundant and at worst can fail. Redundant -- all RAM is marked dirty in migration SETUP state and is transferred only after migration is set to ACTIVE state, so doing log_sync during migration SETUP is pointless. Can fail -- there is a time window, between setting migration state to SETUP and starting dirty tracking by RAM save_live_setup handler, during which dirty tracking is still not started. Any VFIO log_sync call that is issued during this time window will fail. For example, this error can be triggered by migrating a VM when a GUI is active, which constantly calls log_sync. Fix it by skipping VFIO log_sync while migration is in SETUP state.

2023-05-02hw/intc/allwinner-a10-pic: Don't use set_bit()/clear_bit()Peter Maydell
The Allwinner PIC model uses set_bit() and clear_bit() to update the values in its irq_pending[] array when an interrupt arrives. However it is using these functions wrongly: they work on an array of type 'long', and it is passing an array of type 'uint32_t'. Because the code manually figures out the right array element, this works on little-endian hosts and on 32-bit big-endian hosts, where bits 0..31 in a 'long' are in the same place as they are in a 'uint32_t'. However it breaks on 64-bit big-endian hosts. Remove the use of set_bit() and clear_bit() in favour of using deposit32() on the array element. This fixes a bug where on big-endian 64-bit hosts the guest kernel would hang early on in bootup.

2023-05-02hw/net/msf2-emac: Don't modify descriptor in-place in emac_store_desc()Peter Maydell
The msf2-emac ethernet controller has functions emac_load_desc() and emac_store_desc() which read and write the in-memory descriptor blocks and handle conversion between guest and host endianness. As currently written, emac_store_desc() does the endianness conversion in-place; this means that it effectively consumes the input EmacDesc struct, because on a big-endian host the fields will be overwritten with the little-endian versions of their values. Unfortunately, in all the callsites the code continues to access fields in the EmacDesc struct after it has called emac_store_desc() -- specifically, it looks at the d.next field. The effect of this is that on a big-endian host networking doesn't work because the address of the next descriptor is corrupted. We could fix this by making the callsite avoid using the struct; but it's more robust to have emac_store_desc() leave its input alone. (emac_load_desc() also does an in-place conversion, but here this is fine, because the function is supposed to be initializing the struct.)

2023-04-24hw/pci-bridge: Make PCIe and CXL PXB Devices inherit from TYPE_PXB_DEVJonathan Cameron
Previously, PXB_CXL_DEVICE, PXB_PCIE_DEVICE and PXB_DEVICE all have PCI_DEVICE as their direct parent but share a common state struct PXBDev. convert_to_pxb() is used to get the PXBDev instance from which ever of these types it is called on. This patch switches to an explicit hierarchy based on shared functionality. To allow use of OBJECT_DECLARE_SIMPLE_TYPE() whilst minimizing code changes, all types are renamed to have the postfix _DEV rather than _DEVICE. The new heirarchy has PXB_CXL_DEV with parent PXB_PCIE_DEV which in turn has parent PXB_DEV which continues to have parent PCI_DEVICE. This allows simple use of PXB_DEV() etc rather than a custom function + removal of duplicated properties and moving the CXL specific elements out of struct PXBDev.

2023-04-24acpi: pcihp: allow repeating hot-unplug requestsIgor Mammedov
with Q35 using ACPI PCI hotplug by default, user's request to unplug device is ignored when it's issued before guest OS has been booted. And any additional attempt to request device hot-unplug afterwards results in following error: "Device XYZ is already in the process of unplug" arguably it can be considered as a regression introduced by [2], before which it was possible to issue unplug request multiple times. Accept new uplug requests after timeout (1ms). This brings ACPI PCI hotplug on par with native PCIe unplug behavior [1] and allows user to repeat unplug requests at propper times. Set expire timeout to arbitrary 1msec so user won't be able to flood guest with SCI interrupts by calling device_del in tight loop. PS: ACPI spec doesn't mandate what OSPM can do with GPEx.status bits set before it's booted => it's impl. depended. Status bits may be retained (I tested with one Windows version) or cleared (Linux since 2.6 kernel times) during guest's ACPI subsystem initialization. Clearing status bits (though not wrong per se) hides the unplug event from guest, and it's upto user to repeat device_del later when guest is able to handle unplug requests. 1) 18416c62e3 ("pcie: expire pending delete") 2) Fixes: cce8944cc9ef ("qdev-monitor: Forbid repeated device_del") Signed-off-by: Igor Mammedov <imammedo@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> CC: mst@redhat.com CC: anisinha@redhat.com CC: jusual@redhat.com CC: kraxel@redhat.com Message-Id: <20230418090449.2155757-1-imammedo@redhat.com> Reviewed-by: Michael S.

2023-04-24intel_iommu: refine iotlb hash calculationJason Wang
Commit 1b2b12376c8 ("intel-iommu: PASID support") takes PASID into account when calculating iotlb hash like: static guint vtd_iotlb_hash(gconstpointer v) { const struct vtd_iotlb_key *key = v; return key->gfn | ((key->sid) << VTD_IOTLB_SID_SHIFT) | (key->level) << VTD_IOTLB_LVL_SHIFT | (key->pasid) << VTD_IOTLB_PASID_SHIFT; } This turns out to be problematic since: - the shift will lose bits if not converting to uint64_t - level should be off by one in order to fit into 2 bits - VTD_IOTLB_PASID_SHIFT is 30 but PASID is 20 bits which will waste some bits - the hash result is uint64_t so we will lose bits when converting to guint So this patch fixes them by - converting the keys into uint64_t before doing the shift - off level by one to make it fit into two bits - change the sid, lvl and pasid shift to 26, 42 and 44 in order to take the full width of uint64_t - perform an XOR to the top 32bit with the bottom 32bit for the final result to fit guint Fixes: Coverity CID 1508100 Fixes: 1b2b12376c8 ("intel-iommu: PASID support") Signed-off-by: Jason Wang <jasowang@redhat.com> Message-Id: <20230412073510.7158-1-jasowang@redhat.com> Reviewed-by: Michael S.
