/*-
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.

Eliminate redundant information about the host cpu in bhyve's KTR trace points. This is always tracked by ktr(4) and can be displayed using the "-c" option of ktrdump(8). Discussed with: grehan

Add emulation of the "outsb" instruction. NetBSD guests use this to write to the UART FIFO. The emulation is constrained in a number of ways: 64-bit only, doesn't check for all exception conditions, limited to i/o ports emulated in userspace. Some of these constraints will be relaxed in followup commits. Requested by: grehan Reviewed by: tychon (partially and a much earlier version)

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@
