vmm: Use struct vcpu in the instruction emulation code. This passes struct vcpu down in place of struct vm and and integer vcpu index through the in-kernel instruction emulation code. To minimize userland disruption, helper macros are used for the vCPU arguments passed into and through the shared instruction emulation code. A few other APIs used by the instruction emulation code have also been updated to accept struct vcpu in the kernel including vm_get/set_register and vm_inject_fault.

Initial support for bhyve save and restore. Save and restore (also known as suspend and resume) permits a snapshot to be taken of a guest's state that can later be resumed. In the current implementation, bhyve(8) creates a UNIX domain socket that is used by bhyvectl(8) to send a request to save a snapshot (and optionally exit after the snapshot has been taken). A snapshot currently consists of two files: the first holds a copy of guest RAM, and the second file holds other guest state such as vCPU register values and device model state. To resume a guest, bhyve(8) must be started with a matching pair of command line arguments to instantiate the same set of device models as well as a pointer to the saved snapshot. While the current implementation is useful for several uses cases, it has a few limitations. The file format for saving the guest state is tied to the ABI of internal bhyve structures and is not self-describing (in that it does not communicate the set of device models present in the system). In addition, the state saved for some device models closely matches the internal data structures which might prove a challenge for compatibility of snapshot files across a range of bhyve versions. The file format also does not currently support versioning of individual chunks of state. As a result, the current file format is not a fixed binary format and future revisions to save and restore will break binary compatiblity of snapshot files. The goal is to move to a more flexible format that adds versioning, etc. and at that point to commit to providing a reasonable level of compatibility. As a result, the current implementation is not enabled by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option for userland builds, and the kernel option BHYVE_SHAPSHOT.

sys/amd64: further adoption of SPDX licensing ID tags. 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. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. 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.

Improve the performance of the hpet timer in bhyve guests by making the timer frequency a power of two. This changes the frequency from 10 to 16.7 MHz (2 ^ 24 HZ). Using a power of two avoids roundoff errors when doing arithmetic in sbintime_t units. Testing shows this can fix erratic ntpd behavior in guests using the hpet timer (which is the default for multicore guests). Reported by: bsam@

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> Reviewed by: tychon Discussed with: grehan Differential Revision: https://reviews.freebsd.org/D1385 MFC after: 2 weeks

Fix a bug in the HPET emulation where a timer interrupt could be lost when the guest disables the HPET. The HPET timer interrupt is triggered from the callout handler associated with the timer. It is possible for the callout handler to be delayed before it gets a chance to execute. If the guest disables the HPET during this window then the handler never gets a chance to execute and the timer interrupt is lost. This is now fixed by injecting a timer interrupt into the guest if the callout time is detected to be in the past when the HPET is disabled.

Add support for level triggered interrupt pins on the vioapic. Prior to this commit level triggered interrupts would work as long as the pin was not shared among multiple interrupt sources. The vlapic now keeps track of level triggered interrupts in the trigger mode register and will forward the EOI for a level triggered interrupt to the vioapic. The vioapic in turn uses the EOI to sample the level on the pin and re-inject the vector if the pin is still asserted. The vhpet is the first consumer of level triggered interrupts and advertises that it can generate interrupts on pins 20 through 23 of the vioapic. Discussed with: grehan@

Add HPET device emulation to bhyve. bhyve supports a single timer block with 8 timers. The timers are all 32-bit and capable of being operated in periodic mode. All timers support interrupt delivery using MSI. Timers 0 and 1 also support legacy interrupt routing. At the moment the timers are not connected to any ioapic pins but that will be addressed in a subsequent commit. This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).
