MFC 328102: Save and restore guest debug registers.
Currently most of the debug registers are not saved and restored during VM transitions allowing guest and host debug register values to leak into the opposite context. One result is that hardware watchpoints do not work reliably within a guest under VT-x.
Due to differences in SVM and VT-x, slightly different approaches are used.
For VT-x:
- Enable debug register save/restore for VM entry/exit in the VMCS for DR7 and MSR_DEBUGCTL. - Explicitly save DR0-3,6 of the guest. - Explicitly save DR0-3,6-7, MSR_DEBUGCTL, and the trap flag from %rflags for the host. Note that because DR6 is "software" managed and not stored in the VMCS a kernel debugger which single steps through VM entry could corrupt the guest DR6 (since a single step trap taken after loading the guest DR6 could alter the DR6 register). To avoid this, explicitly disable single-stepping via the trace flag before loading the guest DR6. A determined debugger could still defeat this by setting a breakpoint after the guest DR6 was loaded and then single-stepping.
For SVM: - Enable debug register caching in the VMCB for DR6/DR7. - Explicitly save DR0-3 of the guest. - Explicitly save DR0-3,6-7, and MSR_DEBUGCTL for the host. Since SVM saves the guest DR6 in the VMCB, the race with single-stepping described for VT-x does not exist.
For both platforms, expose all of the guest DRx values via --get-drX and --set-drX flags to bhyvectl. |

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task.

We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

This is not properly respecting WITHOUT or ARCH dependencies in target/. Doing so requires a massive effort to rework targets/ to do so. A better approach will be to either include the SUBDIR Makefiles directly and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose the benefit of having a userland/lib, userland/libexec, etc, though and results in a massive package. The current implementation of targets/ is very unmaintainable.

Restructure memory allocation in bhyve to support "devmem".
devmem is used to represent MMIO devices like the boot ROM or a VESA framebuffer where doing a trap-and-emulate for every access is impractical. devmem is a hybrid of system memory (sysmem) and emulated device models.
devmem is mapped in the guest address space via nested page tables similar to sysmem. However the address range where devmem is mapped may be changed by the guest at runtime (e.g. by reprogramming a PCI BAR). Also devmem is usually mapped RO or RW as compared to RWX mappings for sysmem.
Each devmem segment is named (e.g. "bootrom") and this name is used to create a device node for the devmem segment (e.g. /dev/vmm/testvm.bootrom). The device node supports mmap(2) and this decouples the host mapping of devmem from its mapping in the guest address space (which can change).

Simplify instruction restart logic in bhyve.
Keep track of the next instruction to be executed by the vcpu as 'nextrip'. As a result the VM_RUN ioctl no longer takes the %rip where a vcpu should start execution.
Also, instruction restart happens implicitly via 'vm_inject_exception()' or explicitly via 'vm_restart_instruction()'. The APIs behave identically in both kernel and userspace contexts. The main beneficiary is the instruction emulation code that executes in both contexts.
bhyve(8) VM exit handlers now treat 'vmexit->rip' and 'vmexit->inst_length' as readonly: - Restarting an instruction is now done by calling 'vm_restart_instruction()' as opposed to setting 'vmexit->inst_length' to 0 (e.g. emulate_inout()) - Resuming vcpu at an arbitrary %rip is now done by setting VM_REG_GUEST_RIP as opposed to changing 'vmexit->rip' (e.g. vmexit_task_switch())

Replace bhyve's minimal RTC emulation with a fully featured one in vmm.ko.
The new RTC emulation supports all interrupt modes: periodic, update ended and alarm. It is also capable of maintaining the date/time and NVRAM contents across virtual machine reset. Also, the date/time fields can now be modified by 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-time bhyvectl --vm=vm --set-rtc-time=<unix_time_secs> bhyvectl --vm=vm --rtc-nvram-offset=<offset> --get-rtc-nvram bhyvectl --vm=vm --rtc-nvram-offset=<offset> --set-rtc-nvram=<value>

Handle nested exceptions in bhyve.
A nested exception condition arises when a second exception is triggered while delivering the first exception. Most nested exceptions can be handled serially but some are converted into a double fault. If an exception is generated during delivery of a double fault then the virtual machine shuts down as a result of a triple fault.
vm_exit_intinfo() is used to record that a VM-exit happened while an event was being delivered through the IDT. If an exception is triggered while handling the VM-exit it will be treated like a nested exception.
vm_entry_intinfo() is used by processor-specific code to get the event to be injected into the guest on the next VM-entry. This function is responsible for deciding the disposition of nested exceptions.

Restructure the VMX code to enter and exit the guest. In large part this change hides the setjmp/longjmp semantics of VM enter/exit. vmx_enter_guest() is used to enter guest context and vmx_exit_guest() is used to transition back into host context.
Fix a longstanding race where a vcpu interrupt notification might be ignored if it happens after vmx_inject_interrupts() but before host interrupts are disabled in vmx_resume/vmx_launch. We now called vmx_inject_interrupts() with host interrupts disabled to prevent this.

Raise illegal vector errors when attempting to signal an invalid vector for an interrupt or when sending an IPI. - Ignore writes to reserved bits in LVT entries. - Export table entries the MADT and MP Table advertising the stock x86 config of LINT0 set to ExtInt and LINT1 wired to NMI.

Merge projects/bhyve_npt_pmap into head.
Make the amd64/pmap code aware of nested page table mappings used by bhyve guests. 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.

Implement guest vcpu pinning using 'pthread_setaffinity_np(3)'.
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.
