not if it has root privileges, but if the /dev/nvmm device was opened with
write permissions. Introduce the undocumented nvmm_root_init() function to
achieve that.
The goal is to simplify the logic and have more granularity, eg if we want
a monitoring agent to access VMs but don't want to give this agent real
root access on the system.
TPR change. This is supported on all Intel CPUs, and not-too-old AMD CPUs.
The reason for wanting this option is that certain OSes (like Win10 64bit)
manage interrupt priority in hardware via CR8 directly, and for these OSes,
the emulator may want to sync its internal TPR state on each change.
Add two new fields in cap.arch, to report the conf capabilities. Report TPR
only on Intel for now, not AMD, because I don't have a recent AMD CPU on
which to test.
- Remove more unnecessary debug sections
- Use DBG instead of COPTS to specify -Os as defined in bsd.prog.mk
- Use CFLAGS and CPPFLAGS correctly
- Explicitly set -ffreestanding
It looks some cacheline alignment restriction so that zbsdmod.o in
NetBSD/zaurus 8.x release cannot jump to a loaded kernel properly.
Adding an explicit alingment pseudo op to put all instructions
between I-cache flush and jumping to the loaded kernel into the
same cacheline solves the issue.
See my post in port-zaurus@ for details:

Should be pulled up to netbsd-8 and netbsd-9.
This fixes kernel boot failures of NetBSD/zaurus 8.x and later.
While here, also set empty TEXTADDR also specified in ldscript.

libsanitizer needs to match with the compiler concept of
TARGET_ASAN_SHADOW_OFFSET, since the compiler generates instructions
to access memory at that offset in the code, and expects the
sanitizer library to have mapped something there. If there is
disagreement, Mr. Segmentation Fault comes and resolves it for you.
- Alter locking strategy to avoid deadlock on detach.
- Auto bus probe chews CPU. Increase interval from 3s to 10s.
- Put temp sensor S/N in dev description so it can be identified.
- Use mutex/condvar.
Patch from Andrew Doran.
- Sync the naming with reality.
- Replace "relevant" by "desired" and "virtualizer" by "emulator", closer
to what I meant.
- Add a "VCPU Configuration" section.
- Add a "Machine Ownership" section.
