1.1
log
@Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that
provides support for hardware-accelerated virtualization on NetBSD.

It is made of an MI frontend, to which MD backends can be plugged. One
MD backend is implemented, x86-SVM, for x86 AMD CPUs.

We install

	/usr/include/dev/nvmm/nvmm.h
	/usr/include/dev/nvmm/nvmm_ioctl.h
	/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h

And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).

NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.

Sent to tech-kern@@ a month ago. Validated with kASan, and optimized
with tprof.

	sys/modules/nvmm/nvmm.ioconf: revision 1.2

Gather the conditions to return from the VCPU loops in nvmm_return_needed(),
and use it in nvmm_do_vcpu_run() as well. This fixes two undesired behaviors:

 - When a VM initializes, the many nested page faults that need processing
   could cause the calling thread to occupy the CPU too much if we're unlucky
   and are only getting repeated nested page faults thousands of times in a
   row.

 - When the emulator calls nvmm_vcpu_run() and immediately sends a signal to
   stop the VCPU, it's better to check signals earlier and leave right away,
   rather than doing a round of VCPU run that could increase the time spent
   by the emulator waiting for the return.

Register NVMM as an actual pseudo-device. Without PMF handler, to
explicitly disallow ACPI suspend if NVMM is running.

Should fix PR/55406.

Print the backend name when attaching.
