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.

Create a buffer space of 512 bytes before the trapframe.
dtrace fbt needs enough space to emulate an
stp x29, x30, [sp,#-FRAMESIZE]!
instruction in a function prologue. In the aarch64 instruction
encoding, FRAMESIZE can be as large as 512 bytes, so reserve this
much space when KDTRACE_HOOKS is enabled.
Use db_write_bytes to overwrite kernel text.
Tidy up a bit. No functional change intended.
aarch64 fbt_invop doesn't actually use the argument, but it would
make more sense for it to be the return value and/or first argument
register. Certainly it's not `eax'!
Tidy up a bit: don't set things we won't use; assert nonzeroness.
Use /dev/ksyms, not /netbsd, for the running kernel's symbols.
Teach dtrace about el1_trap_exit frames on aarch64.
Implement dtrace_getarg and dtrace_getreg while here.
Count the number of artificial frames in aarch64 fbt probe correctly.
Change the address ranges that aarch64 considers toxic for dtrace.
`Toxic' means dtrace forbids D scripts from even attempting to read
or write at them.
Previously we considered [0, VM_MIN_KERNEL_ADDRESS) toxic, but
VM_MIN_KERNEL_ADDRESS is only the minimum address of the kernel map;
the direct-mapped region lies below it, and with PMAP_MAP_POOLPAGE we
allocate virtual pages for pool backing directly from physical pages
through the direct-mapped region. Also, this did not consider I/O
mappings to be toxic, which they probably should be.
Instead, treat:
[0, AARCH64_KSEG_START)
and
[VM_KERNEL_IO_ADDRESS, 0xfff...ff)
as toxic. (The upper bound for 0xfff...ff ought to be inclusive, not
exclusive, but I think we'll need another mechanism for expressing
that to dtrace!)
Switch from db_write_bytes to using direct-mapping.
This way there's no dependency on ddb.
Define the MULTIPROCESSOR cpu_number() for modules too.
Modules should work whether the main kernel is multiprocessor or not.
In particular, dtrace should not think cpu_number() is 0 while
cpu_index(curcpu()) and curcpu()->ci_index are nonzero, leading to
rather spectacularly bogus results...
cyclic.kmod needs -Wno-sign-compare for aarch64 CPU_INFO_FOREACH.
Provisional workaround; feel free to fix.

sys/modules/filemon/Makefile: revision 1.4 (manually adjusted)
sys/modules/Makefile: revision 1.229
Disable filemon.
It isn't suited for general use (that is, it poses security risks),
but the existence of the module means it is auto-loaded when /dev/filemon
is opened, which can be done by any user.
Thanks Ilja van Sprundel for the heads up.
-
Continue to build the filemon module, but don't install it. Hopefully
this will help us detect any additional bit-rot that might occur.
XXX It might be a good idea to modify the file permissions on /dev/filemon
XXX to prevent auto-loading of the driver module by non-privileged users.

usbnet(9): Add common framework for USB network devices.
This bring various safety fixes to all updated drivers,
and includes locking clean up, detach safety when being
used or not, separate rx/tx locks to improve performance,
porting to NET_MPSAFE, many edge/error case bugs in
drivers fixed, as well as resovling PRs 54303 and 54308.
These drivers are converted: axe(4), axen(4), aue(4),
cdce(4), cue(4), kue(4), mue(4), smsc(4), udav(4),
upl(4), ure(4), url(4), and urndis(4).

- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h

The code was already modularized, we simply didn't build the loadable
module.
Note also that since the tap(4) device can be reasonably accessed by
either creating a device instance (using ifconfig(8)) or by opening
/dev/tap, we need to create both if_tap.kmod and tap.kmod (similar to
what is done with tun(4)).

explicitly set WARNS for modules that fail with WARNS=5.
Also, turn on -Wno-missing-noreturn for clang for some files.
At the moment, among ~ 360 modules,
- 2 (lua and zfs) need WARNS=0
- 1 (solaris) needs WARNS=1
- 136 need WARNS=3 (mostly due to sign-compare)
- 4 need WARNS=4
- others can be compiled with WARNS=5

Make us sure that it should be commented out for release branches in
a similar manner to kernel configuration files.

VMs on Intel CPUs. Overall this implementation is fast and reliable, I am
able to run NetBSD VMs with many VCPUs on a quad-core Intel i5.
NVMM-Intel applies several optimizations already present in NVMM-AMD, and
has a code structure similar to it. No change was needed in the NVMM MI
frontend, or in libnvmm.
Some differences exist against AMD:
- On Intel the ASID space is big, so we don't fall back to a shared ASID
when there are more VCPUs executing than available ASIDs in the host,
contrary to AMD. There are enough ASIDs for the maximum number of VCPUs
supported by NVMM.
- On Intel there are two TLBs we need to take care of, one for the host
(EPT) and one for the guest (VPID). Changes in EPT paging flush the
host TLB, changes to the guest mode flush the guest TLB.
- On Intel there is no easy way to set/fetch the VTPR, so we intercept
reads/writes to CR8 and maintain a software TPR, that we give to the
virtualizer as if it was the effective TPR in the guest.
- On Intel, because of SVS, the host CR4 and LSTAR are not static, so
we're forced to save them on each VMENTRY.
- There is extra Intel weirdness we need to take care of, for example the
reserved bits in CR0 and CR4 when accesses trap.
While this implementation is functional and can already run many OSes, we
likely have a problem on 32bit-PAE guests, because they require special
care on Intel CPUs, and currently we don't handle that correctly; such
guests may misbehave for now (without altering the host stability). I
expect to fix that soon.

Ported from OpenBSD. Support for RX/TX checksum offload added by myself.

- Move the stub routines from zfs_stub.c to zfs_ctldir.c and
remove now empty file zfs_stub.c
- Add stub routines for zfsctl_loadvnode() to initialize control
nodes and zfsctl_snapshot() to retrieve ".zfs/snapshot".
- Add an initial vnode operations vector for control nodes.
- Implement lookup into ".zfs" and lookup ".." from ".zfs/snapshot/<snap>".
- Change nodeid of mounted snapshots to the snapshot object id.
- Respect "-u" flag to "zfs rename <snapshot> ...".

this is not true for alpha, ia64 and arm32 ports, and the first two
were not building because of it, and the latter would be missing
the oabi support (likely not a big deal, but still wrong.)
add a makefile fragment that tells you if it is supported and include
it where needed to define COMPAT_NETBSD32 when building the normal
kernel (ie, modules & rump.)
fixes alpha build, probably fixes ia64 build.
XXX: still leaves some netbsd32 code in rf_netbsdkintf.c, that should
be moved into some hooks, but first the configuration setup
needs to be moved into a common function the netbsd32 code can
call into, vs living in the switch case itself.
