This is a GPLv2 PHY-N implementation based on the Linux b43 driver,
ported over to work in bwn(4).
I've tested this on the BCM4321 11abgn device, in 11bg and 11a modes.
The b43 PHY code only supports 11abg, no 11n, and 20MHz only wide
channels.
Yes, this is a GPLv2 driver, so it won't be included in the
default builds.
Tested:
* BCM4321 11abgn device (Apple!), 11bg and 11a STA mode.
Obtained from: Linux b43
Now that we've got access to SPROM and can access board identification,
this implements all known remaining hardware work-arounds for the bhnd(4)
PCI and PCIe-G1 cores operating endpoint mode.
Additionally, this adds an initial set of skeleton PCIe-G2 hostb and pcib
drivers, required by fullmac and newer softmac devices.

PCIe PHY needs different initialization on MT7628/MT7688 SoCs than it does
on MT7620.
However, LEDE (and OpenWRT) dts files have the PCIe node for MT7628/MT7688
as compatible with mt7620-pci.
We already can handle this properly in our driver, so we just need to add
compat strings to fbsd-mt7628an.dtsi and the PCIe driver.

MT7621 (fbsd-mt7621.dtsi)
MT7628 (fbsd-mt7628an.dtsi)
RT3883 (fbsd-rt3883.dtsi)
So we include the fbsd-*.dtsi files at the end of the original LEDE dtsi
files, using '#include "fbsd-xxxx.dtsi"'.
For example, for MT7621, the LEDE dtsi file is mt7621.dtsi. At the end of
it we add:

That was just wrong. In fact, we can safely keep this static entry when
it's inactive.
Now the destructive action is moved to the reclaim method and the
function is renamed from zfsctl_snapdir_inactive(0 to
zfsctl_snapdir_reclaim().
Also, we can use gfs_vop_reclaim() instead of gfs_dir_inactive() +
kmem_free().
Lastly, we can just assert that the node does not any children when it
is reclaimed, even on the force unmount. That's because zfs_umount()
does an extra vflush() pass which should destroy all snapshot-mountpoint
vnodes that are the snapdir's children.

Dropping the root vnode's lock after VFS_ROOT() didn't really help the
fact that we acquired the lock while holding its child's, .zfs, lock
while performing the operaiton.
So, directly use zfs_zget() to get the root vnode.
While there simplify the code in zfsctl_freebsd_root_lookup.
We know that .zfs is always exclusively locked.
We know that there is already a reference on *vpp, so no need for an
extra one.
Account for the fact that .. lookup may ask for a different lock type,
not necessarily LK_EXCLUSIVE. And handle a possible failure to acquire
the lock given the lock flags.
MFC after: 5 weeks
In fact, that was dangerous. For example, zfsctl_snapshot_reclaim()
calls gfs_dir_lookup() on ".." path and that ends up calling
gfs_lookup_dot() which violated locking order by acquiring the parent's
directory vnode lock after the child's vnode lock.
Also, the previous behavior was inconsistent as gfs_dir_lookup()
returned a locked vnode for . and .. lookups, but not for any other.
Now gfs_lookup_dot() just references a resulting vnode and the locking
is done in its consumers, where necessary.
Note that we do not enable shared locking support for any gfs / zfsctl
vnodes.
This commit partially reverts r273641.
MFC after: 5 weeks
The former acquired a snap vnode lock while holding sd_lock while the
latter does the opposite.
The solution is drop sd_lock before acquiring the vnode lock. That
should be okay as we are still holding a lock on the 'snapshot'
directory in the exclusive mode. That lock ensures that there are no
concurrent lookups in the directory and thus no concurrent mount attempts.
But now we have to account for the possibility that the snap vnode
might get reclaim after we drop sd_lock and before we can get
the node lock. So, check for that case and retry.

TLBs for addresses with updated PTEs are always flushed before pmap
lock is unlocked. On the other hand, amd64 pmap code does not always
flushes TLBs before PV list locks are unlocked, if previously PTEs
were cleared and PV entries removed.
To handle the situations where a thread might notice empty PV list but
third thread still having access to the page due to TLB invalidation
not finished yet, introduce delayed invalidation. Comparing with the
pvh_global_lock, DI does not block entered thread when
pmap_remove_all() or pmap_remove_write() (callers of
pmap_delayed_invl_wait()) are executed in parallel. But _invl_wait()
callers are blocked until all previously noted DI blocks are leaved,
thus ensuring that neccessary TLB invalidations were performed before
returning from pmap_remove_all() or pmap_remove_write().
See comments for detailed description of the mechanism, and also for
the explanations why several pmap methods, most important
pmap_enter(), do not need DI protection.

When a file is opened write-only and a partial block was written,
buffered I/O would try and read the whole block in. This would
result in a hung thread, since there was no open (fuse filehandle)
that allowed reading. This patch avoids the problem by forcing
DIRECT_IO for this case.
It also sets DIRECT_IO when the file system specifies the FN_DIRECTIO
flag in its reply to the open.

bwn_sqrt() is in the PHY-LP code but is also needed by the upcoming
PHY-N support.
The other two routines are used by the PHY-N code.
The next commit will introduce it into the compile and pull bwn_sqrt()
out of the PHY-LP source.
Currently, Application Processors (non-boot CPUs) are started by
MD code at SI_SUB_CPU, but they are kept waiting in a "pen" until
SI_SUB_SMP at which point they are released to run kernel threads.
SI_SUB_SMP is one of the last SYSINIT levels, so APs don't enter
the scheduler and start running threads until fairly late in the
boot.
This change moves SI_SUB_SMP up to just before software interrupt
threads are created allowing the APs to start executing kernel
threads much sooner (before any devices are probed). This allows
several initialization routines that need to perform initialization
on all CPUs to now perform that initialization in one step rather
than having to defer the AP initialization to a second SYSINIT run
at SI_SUB_SMP. It also permits all CPUs to be available for
handling interrupts before any devices are probed.
This last feature fixes a problem on with interrupt vector exhaustion.
Specifically, in the old model all device interrupts were routed
onto the boot CPU during boot. Later after the APs were released at
SI_SUB_SMP, interrupts were redistributed across all CPUs.
However, several drivers for multiqueue hardware allocate N interrupts
per CPU in the system. In a system with many CPUs, just a few drivers
doing this could exhaust the available pool of interrupt vectors on
the boot CPU as each driver was allocating N * mp_ncpu vectors on the
boot CPU. Now, drivers will allocate interrupts on their desired CPUs
during boot meaning that only N interrupts are allocated from the boot
CPU instead of N * mp_ncpu.
Some other bits of code can also be simplified as smp_started is
now true much earlier and will now always be true for these bits of
code. This removes the need to treat the single-CPU boot environment
as a special case.
As a transition aid, the new behavior is available under a new kernel
option (EARLY_AP_STARTUP). This will allow the option to be turned off
if need be during initial testing. I plan to enable this on x86 by
default in a followup commit in the next few days and to have all
platforms moved over before 11.0. Once the transition is complete,
the option will be removed along with the !EARLY_AP_STARTUP code.
These changes have only been tested on x86. Other platform maintainers
are encouraged to port their architectures over as well. The main
things to check for are any uses of smp_started in MD code that can be
simplified and SI_SUB_SMP SYSINITs in MD code that can be removed in
the EARLY_AP_STARTUP case (e.g. the interrupt shuffling).

Rather than blindly removing a supposedly unused variable as reported by
the Clang Static Analyzer, inspect the code and hide them with proper
#ifdefs as they are used in certain conditional parts of the code.
Since r276367 added the virtio_mmio support vtnet_modevent() gets called twice.
This resulted in a memory leak during load and a panic on unload.

Some simulation environments, e.g. gem5, have been found to require more
TLB management from the kernel in certain setups. It is currently unclear why.
Turning on the workaround_erratum383 seems to help and make problems (panics)
go away.
Given this is a fairly uncommon environment so far, allowing the workaround
to be manually enabled from loader in order to make debugging and comparing
traces easier, but also to allow gem5 run FreeBSD in X86 timing mode, seems
to be the least intrusive option for now until the issue if fully understood.

Linux requires that all IOCTL data resides in userspace. FreeBSD
always moves the main IOCTL structure into a kernel buffer before
invoking the IOCTL handler and then copies it back into userspace,
before returning. Hide this difference in the "linux_copyin()" and
"linux_copyout()" functions by remapping userspace addresses in the
range from 0x10000 to 0x20000, to the kernel IOCTL data buffer.
It is assumed that the userspace code, data and stack segments starts
no lower than memory address 0x400000, which is also stated by "man 1
ld", which means any valid userspace pointer can be passed to regular
LinuxKPI handled IOCTLs.
Bump the FreeBSD version to force recompilation of all kernel modules.

When the multicast filters we're allowed to insert are controlled by the
hypervisor, it may be that we can insert some but not others. So we need
to have fallbacks where we insert any filters we can without rolling back
when one fails to insert.

On WIN8 like host systems, when rescan happens, the already installed
disks seem to return random invalid results for INQUIRY.
More investigation is under way to figure out why random invalid INQUIRY
results are delivered to VM on WIN8 like host systems.

None of the sysctl handlers in hdaa use the arg2 parameter, so just pass zero
instead. Additionally, the sizes being passed in were suspect (size of the

- Introduce new OF API function OF_prop_free to free memory allocated by
OF_getprop_alloc and OF_getencprop_alloc. Current code just calls free(9)
with M_OFWPROP memory class which assumes knowledge about OF_*prop_alloc
functions' internals and leads to unneccessary code coupling
- Convert some of the free(..., M_OFWPROP) instances to OF_prop_free
Files affected by this commit are the ones I was able to test on real
hardware. The rest of free(..., M_OFWPROP) instances will be handled with
idividual maintainers

It acts as a virtual keyboard, so keys are visible through kbdmux(4)
Driver maps linux scancodes for most common keys to FreeBSD scancodes and
also extends spec by introducing freebsd,code property to specify
FreeBSD-native scancodes.

detect failures, and get different PCI IDs.
For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.
For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.
A follow up commit will be made to remove pci_get_rid.
