| | | | | | | | | | | | | | | | | | | | | | | | | Add virtualized XSAVE support to bhyve which permits guests to use XSAVE and XSAVE-enabled features like AVX. - Store a per-cpu guest xcr0 register and handle xsetbv VM exits by emulating the instruction. - Only expose XSAVE to guests if XSAVE is enabled in the host. Only expose a subset of XSAVE features currently supported by the guest and for which the proper emulation of xsetbv is known. Currently this includes X87, SSE, AVX, AVX-512, and Intel MPX. - Add support for injecting hardware exceptions into the guest and use this to trigger exceptions in the guest for invalid xsetbv operations instead of potentially faulting in the host. - Queue pending exceptions in the 'struct vcpu' instead of directly updating the processor-specific VMCS or VMCB. The pending exception will be delivered right before entering the guest. - Rename the unused ioctl VM_INJECT_EVENT to VM_INJECT_EXCEPTION and restrict it to only deliver x86 hardware exceptions. This new ioctl is now used to inject a protection fault when the guest accesses an unimplemented MSR. - Expose a subset of known-safe features from leaf 0 of the structured extended features to guests if they are supported on the host including RDFSBASE/RDGSBASE, BMI1/2, AVX2, AVX-512, HLE, ERMS, and RTM. Aside from AVX-512, these features are all new instructions available for use in ring 3 with no additional hypervisor changes needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several changes to the local APIC support in bhyve: - Rename 'vm_interrupt_hostcpu()' to 'vcpu_notify_event()'. - If a vcpu disables its local apic and then executes a 'HLT' then spin down the vcpu and destroy its thread context. Also modify the 'HLT' processing to ignore pending interrupts in the IRR if interrupts have been disabled by the guest. The interrupt cannot be injected into the guest in any case so resuming it is futile. - Use callout(9) to drive the vlapic timer instead of clocking it on each VM exit. - When the guest is bringing up the APs in the x2APIC mode a write to the ICR register will now trigger a return to userspace with an exitcode of VM_EXITCODE_SPINUP_AP. - Change the vlapic timer lock to be a spinlock because the vlapic can be accessed from within a critical section (vm run loop) when guest is using x2apic mode. - Fix the vlapic version register. - Add a command to bhyvectl to inject an NMI on a specific vcpu. - Add an API to deliver message signalled interrupts to vcpus. This allows callers to treat the MSI 'addr' and 'data' fields as opaque and also lets bhyve implement multiple destination modes: physical, flat and clustered. - Rename the ambiguously named 'vm_setup_msi()' and 'vm_setup_msix()' to 'vm_setup_pptdev_msi()' and 'vm_setup_pptdev_msix()' respectively. - Consolidate the virtual apic initialization in a single function: vlapic_reset() - Add a generic routine to trigger an LVT interrupt that supports both fixed and NMI delivery modes. - Add an ioctl and bhyvectl command to trigger local interrupts inside a guest. In particular, a global NMI similar to that raised by SERR# or PERR# can be simulated by asserting LINT1 on all vCPUs. - Extend the LVT table in the vCPU local APIC to support CMCI. - Flesh out the local APIC error reporting a bit to cache errors and report them via ESR when ESR is written to. Add support for asserting the error LVT when an error occurs. Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Export table entries in the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

This allows bhyve to associate each guest with its own vmspace and deal with nested page faults in the context of that vmspace. This also enables features like accessed/dirty bit tracking, swapping to disk and transparent superpage promotions of guest memory. Guest vmspace: Each bhyve guest has a unique vmspace to represent the physical memory allocated to the guest. Each memory segment allocated by the guest is mapped into the guest's address space via the 'vmspace->vm_map' and is backed by an object of type OBJT_DEFAULT. pmap types: The amd64/pmap now understands two types of pmaps: PT_X86 and PT_EPT. The PT_X86 pmap type is used by the vmspace associated with the host kernel as well as user processes executing on the host. The PT_EPT pmap is used by the vmspace associated with a bhyve guest. Page Table Entries: The EPT page table entries as mostly similar in functionality to regular page table entries although there are some differences in terms of what bits are used to express that functionality. For e.g. the dirty bit is represented by bit 9 in the nested PTE as opposed to bit 6 in the regular x86 PTE. Therefore the bitmask representing the dirty bit is now computed at runtime based on the type of the pmap. Thus PG_M that was previously a macro now becomes a local variable that is initialized at runtime using 'pmap_modified_bit(pmap)'. An additional wrinkle associated with EPT mappings is that older Intel processors don't have hardware support for tracking accessed/dirty bits in the PTE. This means that the amd64/pmap code needs to emulate these bits to provide proper accounting to the VM subsystem. This is achieved by using the following mapping for EPT entries that need emulation of A/D bits: Bit Position Interpreted By PG_V 52 software (accessed bit emulation handler) PG_RW 53 software (dirty bit emulation handler) PG_A 0 hardware (aka EPT_PG_RD) PG_M 1 hardware (aka EPT_PG_WR) The idea to use the mapping listed above for A/D bit emulation came from Alan Cox (alc@). The final difference with respect to x86 PTEs is that some EPT implementations do not support superpage mappings. This is recorded in the 'pm_flags' field of the pmap. TLB invalidation: The amd64/pmap code has a number of ways to do invalidation of mappings that may be cached in the TLB: single page, multiple pages in a range or the entire TLB. All of these funnel into a single EPT invalidation routine called 'pmap_invalidate_ept()'. This routine bumps up the EPT generation number and sends an IPI to the host cpus that are executing the guest's vcpus. On a subsequent entry into the guest it will detect that the EPT has changed and invalidate the mappings from the TLB. Guest memory access: Since the guest memory is no longer wired we need to hold the host physical page that backs the guest physical page before we can access it. The helper functions 'vm_gpa_hold()/vm_gpa_release()' are available for this purpose. PCI passthru: Guest's with PCI passthru devices will wire the entire guest physical address space. The MMIO BAR associated with the passthru device is backed by a vm_object of type OBJT_SG. An IOMMU domain is created only for guest's that have one or more PCI passthru devices attached to them. Limitations: There isn't a way to map a guest physical page without execute permissions. This is because the amd64/pmap code interprets the guest physical mappings as user mappings since they are numerically below VM_MAXUSER_ADDRESS. Since PG_U shares the same bit position as EPT_PG_EXECUTE all guest mappings become automatically executable. Thanks to Alan Cox and Konstantin Belousov for their rigorous code reviews as well as their support and encouragement. Thanks for John Baldwin for reviewing the use of OBJT_SG as the backing object for pci passthru mmio regions. Special thanks to Peter Holm for testing the patch on short notice.

Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.

* Implement guest vcpu pinning using 'pthread_setaffinity_np(3)'.neel2013-02-112-30/+0
| | | | | | | | | | | | | | Prior to this change pinning was implemented via an ioctl (VM_SET_PINNING) that called 'sched_bind()' on behalf of the user thread. The ULE implementation of 'sched_bind()' bumps up 'td_pinned' which in turn runs afoul of the assertion '(td_pinned == 0)' in userret(). Using the cpuset affinity to implement pinning of the vcpu threads works with both 4BSD and ULE schedulers and has the happy side-effect of getting rid of a bunch of code in vmm.ko.

* Remove mptable generation code from libvmmapi and move it to bhyve.grehan2012-10-265-528/+1
| | | | | | | | | | | | Firmware tables require too much knowledge of system configuration, and it's difficult to pass that information in general terms to a library. The upcoming ACPI work exposed this - it will also livein bhyve. Also, remove code specific to NetApp from the mptable name, and remove the -n option from bhyve.
