neel	633860276f	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@	2013-11-27 22:18:08 +00:00
neel	023e2d37dd	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	2013-11-22 18:57:22 +00:00
neel	74368cc42d	Rename the VMM_CTRx() family of macros to VCPU_CTRx() to highlight that these ... tracepoints are vcpu-specific. Add support for tracepoints that are global to the virtual machine - these tracepoints are called VM_CTRx().	2013-10-31 05:20:11 +00:00
