- Explain why we don't enable infinite bursts on sparc64.
- Given that these chips support memory write invalidate, make sure that
it's enabled in the command register. Also make sure that PERR# and
SERR# assertion is enabled.

- Use NULL instead of 0 for pointers.
- Let ofw_pcib_probe() return BUS_PROBE_DEFAULT instead of 0 so specialized
PCI-PCI-bridge drivers may attach instead.
- Add WARs for PLX Technology PEX 8114 bridges and PEX 8532 switches.
Ideally, these should live in MI code but at least for the latter we're
missing the necessary infrastructure there.

neither DEFAULT_RCLK * 2 nor DEFAULT_RCLK * 10 but plain DEFAULT_RCLK
and there's no (open) source indicating otherwise. This was tested with
an EXSYS EX-41098-2, whose clock is not configurable and identifies as:
puc0@pci0:5:1:0: class=0x070200 card=0x06711415 chip=0x95381415 rev=0x01 hdr=0x00
vendor = 'Oxford Semiconductor Ltd'
class = simple comms
subclass = multiport serial
Note that this exactly matches the card mentioned in PR 129665 so no
sub-device/sub-vendor based quirking of the latter is possible. So maybe
we should grow some sort of tunable, in case non-default cards such as
the latter aren't configurable either (this also wouldn't be the first
time an allegedly tested commit turns out to be wrong though).

aac_command_status_table, which is actually unused since r111532.
While at it, make aac_if a pointer to the now const interface tables
instead of copying them over to the softc (this alone already reduces the
size of aac.ko on amd64 by ~1 KiB).
- Remove redundant softc members.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
- Remove redundant bzero(9)'ing of the softc.
- Use pci_enable_busmaster(9) instead of duplicating it.
- Remove redundant checking for PCIM_CMD_MEMEN (resource allocation will
just fail).
- Canonicalize the error messages in case of resource allocation failures.
- Add support for using MSI instead of INTx, controllable via the tunable
hw.aac.enable_msi (defaulting to on).

directory entry, matched by the inode number, is ".".
NFSv4 client might instantiate the distinct vnodes which have the same
inode number, since single v4 export can be combined from several
filesystems on the server. For instance, a case when the nested
server mount point is exactly one directory below the top of the
export, causes directory and its parent to have the same inode number
2. The vop_stdvptocnp() algorithm then returns "." as the name of the
lower directory.
Filtering out the "." entry with ENOENT works around this behaviour,
the error forces getcwd(3) to fall back to usermode implementation,
which compares both st_dev and st_ino.

in r247265 (ZFS deadman thread). Both new utilities now support the old
kernel and new kernel properly detects old utilities.
For future backwards compatibility, the vfs.zfs.version.ioctl read-only
sysctl has been introduced. With this sysctl zfs utilities will be able
to detect the ioctl interface version of the currently loaded zfs module.
As a side effect, the zfs utilities between r247265 and this revision don't
support the old kernel module. If you are using HEAD newer or equal than
r247265, install the new kernel module (or whole kernel) first.

This seems prudent to do in its own right but it also opens up the possibility
of not having to mmap the entire guest address space in the 'bhyve' process

A10 uart is derived from Synopsys DesignWare uart and requires
to read Uart Status Register when IIR_BUSY has detected.
Also this change includes FDT check, where it checks device
specific properties defined in dts and sets the busy_detect variable.
broken_txfifo is also needed to be set in order to make it work for
A10 uart case.

I stumbled across this whilst trying to debug another weird hang reported
on the freebsd-wireless list.
Whilst here, add in the STBC check to ath_rateseries_setup().
Whilst here, fix the short preamble flag to be set only for legacy rates.
Whilst here, comment that we should be using the full set of decisions
made by ath_rateseries_setup() rather than recalculating them!
In order to use platorm backend hardware driver should
impement three methods:
- platform_start_transfer and platform_finish_transfer
to start and finish transfer
- platform_will_handle - check whether transaction is
suitable for backend. If not - driver will fall back
to PIO mode.

Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.
When CPU becomes idle, cpu_idleclock() calculates time to the next timer
event in order to reprogram hw timer. Return that time in sbintime_t to
the caller and pass it to acpi_cpu_idle(), where it can be used as one
more factor (quite precise) to extimate furter sleep time and choose
optimal sleep state. This is a preparatory change for further callout
improvements will be committed in the next days.
The commmit is not targeted for MFC.
using 32.32 fixed point in form of single int64_t. It is much easier to
use in cases where additional precision and range of struct bintime is
not required.

reconnected in the meantime. Check if reset is set before opening next trail
file, as not doing so will result in sending OPEN message with the same
file name twice and this is illegal - the second OPEN is send without first
closing previous trail file.
routines provide write-only stdio FILE objects that store their data in a
dynamically allocated buffer. They are a string builder interface somewhat
akin to a completely dynamic sbuf.
