Some SAS JBODs support zoning. This feature allows individual SAS
targets to be accessible by only some initiator ports. One application
would be connecting two servers to the same JBOD, but they wouldn't be
able to see each other's disks.
A zoned JBOD should also prohibit initiators from accessing SES elements
corresponding to inaccessible SAS targets. It reports that by setting
the element's status code to 0x8 (No Access Allowed).
The bug is that when doing "sesutil (fault|locate) all ...", sesutil
will attempt a ENCIOC_SETELMSTAT ioctl for every single element, even
the inaccessible ones. The enclosure will reject the command, the
kernel will return EINVAL, and sesutil will exit.
The solution is to check the element's status, and skip trying to set it
if the status is 0x8. But if the user actually supplied a ses ID, then
assume that he knows what he's doing and try to set it anyway.

The Intel GOP driver checks the LPC IDs to detect the platform it's
running on. The GOP driver only works on the platforms it's written for.
Maybe other Intel driver have the same behaviour. For that reason, we
should use the LPC IDs of the FreeBSD host for GPU passthrough to work
properly.
We don't know if setting different LPC IDs have any side effect.
Therefore, don't use the host LPC IDs by default on Intel system. Give
the user the opportunity to modify the LPC IDs.

Changing the PCI IDs is valuable in some situations. The Intel GOP
driver requires that some PCI IDs of the LPC bridge are aligned with the
physical values of the host LPC bridge. Another use case are oracles
virtio driver. They require different subvendor ID than the default one.
For that reason, create a helper which makes it easy to read PCI IDs
from bhyve config. Additionally, this helper ensures that all emulation
devices are using the same config keys.

We previously attempted to emit Rock Ridge NM records only when the name
represented by the Rock Ridge extensions would actually differ. We would
omit the record for an all-upper-case directory name, however Linux (and
perhaps other operating systems) map names with no NM record to
lowercase.
This affected only directories, as file names have an implicit ";1"
version number appended and thus always differ. To solve, just emit NM
records for all entries other than DOT and DOTDOT .
We could continue to omit the NM record for directories that would avoid
mapping (for example, one named 1234.567) but this does not seem worth
the complexity.

This is a userland-only pointer that isn't relevant to the kernel and
doesn't belong in the ioctl structure shared between userland and the
kernel. For the kernel, the old structure for the ioctl is still
supported under COMPAT_FREEBSD13.
This changes vm_snapshot_req() in libvmmapi to accept an explicit
vmctx argument.
It also changes vm_snapshot_guest2host_addr to take an explicit vmctx
argument. As part of this change, move the declaration for this
function and its wrapper macro from vmm_snapshot.h to snapshot.h as it
is a userland-only API.

This replaces the 'struct vm, int vcpuid' tuple passed to most API
calls and is similar to the changes recently made in vmm(4) in the
kernel.
struct vcpu is an opaque type managed by libvmmapi. For now it stores
a pointer to the VM context and an integer id.
As an immediate effect this removes the divergence between the kernel
and userland for the instruction emulation code introduced by the
recent vmm(4) changes.
Since this is a major change to the vmmapi API, bump VMMAPI_VERSION to
0x200 (2.0) and the shared library major version.
While here (and since the major version is bumped), remove unused
vcpu argument from vm_setup_pptdev_msi*().
Add new functions vm_suspend_all_cpus() and vm_resume_all_cpus() for
use by the debug server. The underyling ioctl (which uses a vcpuid of
-1) remains unchanged, but the userlevel API now uses separate
functions for global CPU suspend/resume.

As of commit 0bda8d3e9f ("vmm: permit some IPIs to be handled by
userspace") and commit 9cc9abf409 ("bhyve: create all vcpus on
startup"), we have a misbehaviour where AP vCPU threads spin until they
receive a SIPI. In particular, since they are "suspended", they simply
call the VMEXIT_DEBUG handler in a loop, but the handler is a no-op by
default.
This is tricky to fix since the gdb stub isn't aware of whether a given
vCPU is supposed to be running. For 13.2's sake, introduce a simple
workaround wherein the VMEXIT_DEBUG handler sleeps for a short period.
This ensures that host CPU usage remains sane when VMs are starting
without penalizing users of VMEXIT_DEBUG too much.

Add missing brelse(bp). Without it the cache grows and we have a n^2
lookup. I'm not entirely sure why we read the block before we write it
back out, since the only side effect of that is to allocate memory,
clear the memory, read it in from disk, throw it away with the contents
of the file being written out. We likely should just do a getblk() here
instead, but even with all that, this takes the time it takes to create
a 150MB msdos fs image down from 5 minutes to 30 seconds.
