2024-05-22vfio/display: Fix error path in call site of ramfb_setup()Zhenzhong Duan1-0/+6
vfio_display_dmabuf_init() and vfio_display_region_init() calls ramfb_setup() without checking its return value. So we may run into a situation that vfio_display_probe() succeed but errp is set. This is risky and may lead to assert failure in error_setv().

2024-05-16vfio/migration: Don't emit STOP_COPY VFIO migration QAPI event twiceAvihai Horon1-0/+4
When migrating a VFIO device that supports pre-copy, it is transitioned to STOP_COPY twice: once in vfio_vmstate_change() and second time in vfio_save_complete_precopy(). The second transition is harmless, as it's a STOP_COPY->STOP_COPY no-op transition. However, with the newly added VFIO migration QAPI event, the STOP_COPY event is undesirably emitted twice. Prevent this by returning early in vfio_migration_set_state() if new_state is the same as current device state. Note that the STOP_COPY transition in vfio_save_complete_precopy() is essential for VFIO devices that don't support pre-copy, for migrating an already stopped guest and for snapshots.

Add a new QAPI event for VFIO migration. This event will be emitted when a VFIO device changes its migration state, for example, during migration or when stopping/starting the guest. This event can be used by management applications to get updates on the current state of the VFIO device for their own purposes. Note that this new event is introduced since VFIO devices have a unique set of migration states which cannot be described as accurately by other existing events such as run state or migration status.

2024-05-16vfio/pci: migration: Skip config space check for Vendor Specific Information ↵Vinayak Kale3-0/+28
in VSC during restore/load In case of migration, during restore operation, qemu checks config space of the pci device with the config space in the migration stream captured during save operation. In case of config space data mismatch, restore operation is failed. config space check is done in function get_pci_config_device(). By default VSC (vendor-specific-capability) in config space is checked. Due to qemu's config space check for VSC, live migration is broken across NVIDIA vGPU devices in situation where source and destination host driver is different. In this situation, Vendor Specific Information in VSC varies on the destination to ensure vGPU feature capabilities exposed to the guest driver are compatible with destination host. If a vfio-pci device is migration capable and vfio-pci vendor driver is OK with volatile Vendor Specific Info in VSC then qemu should exempt config space check for Vendor Specific Info. It is vendor driver's responsibility to ensure that VSC is consistent across migration. Here consistency could mean that VSC format should be same on source and destination, however actual Vendor Specific Info may not be byte-to-byte identical. This patch skips the check for Vendor Specific Information in VSC for VFIO-PCI device by clearing pdev->cmask[] offsets. Config space check is still enforced for 3 byte VSC header. If cmask[] is not set for an offset, then qemu skips config space check for that offset. VSC check is skipped for machine types >= 9.1. The check would be enforced on older machine types (<= 9.0).

2024-05-16scripts/update-linux-header.sh: be more src tree friendlyAlex Bennée1-39/+41
Running "install_headers" in the Linux source tree is fairly unfriendly as out-of-tree builds will start complaining about the kernel source being non-pristine. As we have a temporary directory for the install we should also do the build step here. So now we have: $tmpdir/ $blddir/ $hdrdir/ Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Reviewed-by: Michael S.

2024-05-15target/hppa: Implement CF_PCRELRichard Henderson2-32/+55
Now that the groundwork has been laid, enabling CF_PCREL within the translator proper is a simple matter of updating copy_iaoq_entry and install_iaq_entries. We also need to modify the unwind info, since we no longer have absolute addresses to install. As expected, this reduces the runtime overhead of compilation when running a Linux kernel with address space randomization enabled.
