74ada297 - AMD-vi: Fix IOMMU device interrupts being overridden

Mon, 22 Mar 2021 09:33:43 +0000

AMD-vi: Fix IOMMU device interrupts being overriddenCurrently, AMD-vi PCI-e passthrough will lead to the following lines indmesg:"kernel: CPU0: local APIC error 0x40ivhd0: Error: completion failed tail:0x720, head:0x0."After some tracing, the problem is due to the interaction withamdvi_alloc_intr_resources() and pci_driver_added(). In ivrs_drv, theidentification of AMD-vi IVHD is done by walking over the ACPI IVRStable and ivhdX device_ts are added under the acpi bus, while there areno driver handling the corresponding IOMMU PCI function. Inamdvi_alloc_intr_resources(), the MSI intr are allocated with the ivhdXdevice_t instead of the IOMMU PCI function device_t. bus_setup_intr() iscalled on ivhdX. the IOMMU pci function device_t is only used forpci_enable_msi(). Since bus_setup_intr() is not called on IOMMU pcifunction, the IOMMU PCI function device_t's dinfo->cfg.msi is neverupdated to reflect the supposed msi_data and msi_addr. So the msi_dataand msi_addr stay in the value 0. When pci_driver_added() tried to loopover the children of a pci bus, and do pci_cfg_restore() on each ofthem, msi_addr and msi_data with value 0 will be written to the MSIcapability of the IOMMU pci function, thus explaining the errors indmesg.This change includes an amdiommu driver which currently does attaching,detaching and providing DEVMETHODs for setting up and tearing downinterrupt. The purpose of the driver is to prevent pci_driver_added()from calling pci_cfg_restore() on the IOMMU PCI function device_t.The introduction of the amdiommu driver handles allocation of an IRQresource within the IOMMU PCI function, so that the dinfo->cfg.msi ispopulated.This has been tested on EPYC Rome 7282 with Radeon 5700XT GPU.Sponsored by: The FreeBSD FoundationReviewed by: jhbApproved by: philip (mentor)MFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D28984 List of files: /freebsd-14.2/sys/modules/vmm/Makefile

483d953a - Initial support for bhyve save and restore.

Tue, 05 May 2020 00:02:04 +0000

Initial support for bhyve save and restore.Save and restore (also known as suspend and resume) permits a snapshotto be taken of a guest's state that can later be resumed. In thecurrent implementation, bhyve(8) creates a UNIX domain socket that isused by bhyvectl(8) to send a request to save a snapshot (andoptionally exit after the snapshot has been taken). A snapshotcurrently consists of two files: the first holds a copy of guest RAM,and the second file holds other guest state such as vCPU registervalues and device model state.To resume a guest, bhyve(8) must be started with a matching pair ofcommand line arguments to instantiate the same set of device models aswell as a pointer to the saved snapshot.While the current implementation is useful for several uses cases, ithas a few limitations. The file format for saving the guest state istied to the ABI of internal bhyve structures and is notself-describing (in that it does not communicate the set of devicemodels present in the system). In addition, the state saved for somedevice models closely matches the internal data structures which mightprove a challenge for compatibility of snapshot files across a rangeof bhyve versions. The file format also does not currently supportversioning of individual chunks of state. As a result, the currentfile format is not a fixed binary format and future revisions to saveand restore will break binary compatiblity of snapshot files. Thegoal is to move to a more flexible format that adds versioning,etc. and at that point to commit to providing a reasonable level ofcompatibility. As a result, the current implementation is not enabledby default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes optionfor userland builds, and the kernel option BHYVE_SHAPSHOT.Submitted by: Mihai Tiganus, Flavius Anton, Darius MihaiSubmitted by: Elena Mihailescu, Mihai Carabas, Sergiu WeiszRelnotes: yesSponsored by: University Politehnica of BucharestSponsored by: Matthew Grooms (student scholarships)Sponsored by: iXsystemsDifferential Revision: https://reviews.freebsd.org/D19495 List of files: /freebsd-14.2/sys/modules/vmm/Makefile

488adf43 - Fix cyclic dependency after r326552.

Tue, 05 Dec 2017 17:23:33 +0000

Fix cyclic dependency after r326552.The OBJS_DEPEND_GUESS mechanism was making vmx_genassym.o dependon all headers along with vmx_assym.h, though vmx_assym.h dependson having vmx_genassym.o present to generate. Moving the headersto DPSRCS is enough to resolve the issue as they will no longerbe implicit dependencies for all objects. Because of this weneed explicit OBJS_DEPEND_GUESS entries to ensure the headersare generated when needed for the *_support.o files that needthem.X-MFC-With: r326552MFC after: 2 weeksSponsored by: Dell EMC List of files: /freebsd-14.2/sys/modules/vmm/Makefile

Tue, 30 Dec 2014 22:19:34 +0000

Replace bhyve's minimal RTC emulation with a fully featured one in vmm.ko.The new RTC emulation supports all interrupt modes: periodic, update endedand alarm. It is also capable of maintaining the date/time and NVRAM contentsacross virtual machine reset. Also, the date/time fields can now be modifiedby the guest.Since bhyve now emulates both the PIT and the RTC there is no need for"Legacy Replacement Routing" in the HPET so get rid of it.The RTC device state can be inspected via bhyvectl as follows:bhyvectl --vm=vm --get-rtc-timebhyvectl --vm=vm --set-rtc-time=bhyvectl --vm=vm --rtc-nvram-offset= --get-rtc-nvrambhyvectl --vm=vm --rtc-nvram-offset= --set-rtc-nvram=Reviewed by: tychonDiscussed with: grehanDifferential Revision: https://reviews.freebsd.org/D1385MFC after: 2 weeks List of files: /freebsd-14.2/sys/modules/vmm/Makefile

c3498942 - Restructure the MSR handling so it is entirely handled by processor-specific

Sat, 20 Sep 2014 02:35:21 +0000

Restructure the MSR handling so it is entirely handled by processor-specificcode. There are only a handful of MSRs common between the two so there isn'ttoo much duplicate functionality.The VT-x code has the following types of MSRs:- MSRs that are unconditionally saved/restored on every guest/host context switch (e.g., MSR_GSBASE).- MSRs that are restored to guest values on entry to vmx_run() and saved before returning. This is an optimization for MSRs that are not used in host kernel context (e.g., MSR_KGSBASE).- MSRs that are emulated and every access by the guest causes a trap into the hypervisor (e.g., MSR_IA32_MISC_ENABLE).Reviewed by: grehan List of files: /freebsd-14.2/sys/modules/vmm/Makefile
