This branch is now considered frozen: future bhyve development will take place in a branch off -CURRENT. sys/dev/bvm/bvm_console.c sys/dev/bvm/bvm_dbg.c - simple console driver/gdb debug port used for bringup. supported by user-space bhyve executable sys/conf/options.amd64 sys/amd64/amd64/minidump_machdep.c - allow NKPT to be set in the kernel config file sys/amd64/conf/GENERIC - mptable config options; bhyve user-space executable creates an mptable with number of CPUs, and optional vendor extension - add bvm console/debug - set NKPT to 512 to allow loading of large RAM disks from the loader - include kdb/gdb sys/amd64/amd64/local_apic.c sys/amd64/amd64/apic_vector.S sys/amd64/include/specialreg.h - if x2apic mode available, use MSRs to access the local APIC, otherwise fall back to 'classic' MMIO mode sys/amd64/amd64/mp_machdep.c - support AP spinup on CPU models that don't have real-mode support by overwriting the real-mode page with a message that supplies the bhyve user-space executable with enough information to start the AP directly in 64-bit mode. sys/amd64/amd64/vm_machdep.c - insert pause statements into cpu shutdown busy-wait loops sys/dev/blackhole/blackhole.c sys/modules/blackhole/Makefile - boot-time loadable module that claims all PCI bus/slot/funcs specified in an env var that are to be used for PCI passthrough sys/amd64/amd64/intr_machdep.c - allow round-robin assignment of device interrupts to CPUs to be disabled from the loader sys/amd64/include/bus.h - convert string ins/outs instructions to loops of individual in/out since bhyve doesn't support these yet sys/kern/subr_bus.c - if the device was no created with a fixed devclass, then remove it's association with the devclass it was associated with during probe. Otherwise, new drivers do not get a chance to probe/attach since the device will stay married to the first driver that it probed successfully but failed to attach. Sponsored by: NetApp, Inc.
