8183f2e312 Fix filemon locking races.
Convert filemon_lock and struct filemon* lock to sx(9), rather than a
self-rolled reader-writer lock, and hold it for the entire time needed.

At least filemon_lock_write() was not checking for active readers when
it would successfully return with the write lock "held".  This led to
a race with reading entries from filemon_inuse as they were removed.  This
could be seen with QUEUE_MACRO_DEBUG enabled, causing -1 to be read as an
entry rather than a valid struct filemon*.

Fixing filemon_lock_write() to check readers was insufficient to fix the
races.

sx(9) was used as the lock could be held while taking proctree_lock and sleeping
in fo_write.

e974f91c38 Import ioat(4) driver
I/OAT is also referred to as Crystal Beach DMA and is a Platform Storage
Extension (PSE) on some Intel server platforms.

This driver currently supports DMA descriptors only and is part of a
larger effort to upstream an interconnect between multiple systems using
the Non-Transparent Bridge (NTB) PSE.

For now, this driver is only built on AMD64 platforms.  It may be ported
to work on i386 later, if that is desired.  The hardware is exclusive to
x86.

Further documentation on ioat(4), including API documentation and usage,
can be found in the new manual page.

Bring in a test tool, ioatcontrol(8), in tools/tools/ioat.  The test
tool is not hooked up to the build and is not intended for end users.

e6f4757735 When forking a child process with PMC_F_DESCENDANTS set in pmc_attach()
in the parent, we will inherit the pmcids but cannot execute any operations
on them in the child.  The reason for this is that pmc_find_pmc() only
tries to find the current process on the owners hash list, but given the
child does not own the attachment, we cannot find it.
Thus, in case the initial lookup fails, try to find the pmc_process state
affiliated with the child process, lookup the pmc from there using the
row index, and get the owner process from that pmc.
Then continue as normal and lookup the pmc context of the owner (process).

This allows us to call, e.g., pmc_start() in the child process before we
start the work there, but to collect the accumulated results later in
the parent.

6aabc119b6 Create a RouterBoard platform and use it to create a flash map
Summary:
The RouterBoard uses a predefined partition map which doesn't exist in the fdt.
This change allows overriding the fdt slicer with a custom slicer, and uses this
custom slicer to define the flash map on the RouterBoard RB800.
D3305 converts the mpc85xx platform into a base class, so that systems based on
the mpc85xx platform can add their own overrides.  This change builds on D3305,
and creates a RouterBoard (RB800) platform to initialize the slicer override.

076cf2dd66 Using the error return code documented in the comment.
Though there is no direct midi_uninit() caller amongst existing drivers
at this moment, a quick experiment indicates that EBUSY gives users more
precise error message once drivers start to honour this result.  For example,
emu_midi_detach() should check the result of mpu401_uninit() and block
module unloading if there is any MIDI I/O in progress.

the height and width to those defaults and position the screen
in the center of the frame buffer.

Ideally we use a bigger font to utility the entire real estate
that is the frame buffer, but that's seen as an improvement over
making it work first.

296a51148d Improve support for Macs that have a stride not equal to the
horizonal resolution (width). In those cases fb_bpp ended up
completely wrong -- as in 6 bytes per pixel or something like
that. Since we already have a way to calculate fb_depth given
the masks and fb_bpp is effectively the same as fb_depth, all
we need to do is make sure fb_bpp is rounded to the next
multiple of the number of bits in a byte -- we assume we can
divide by the number of bits in a byte throughout vt(4).
While here:
-   simplify how we calculate fb_depth.
-   use fb_bpp instead of fb_depth to calculate fb_stride;
    we know we can divide fb_bpp.
-   don't limit fb_width and fb_height by VT_FB_DEFAULT_WIDTH
    and VT_FB_DEFAULT_HEIGHT (resp.). Those constants have
    not relation to the size of the frame buffer.

This at least fixes "lower-resolution" Macs. We're talking
1280x1024 or so. There still is a problem with 27" Macs,
which typically have a horizontal resolution over 2K.

43ea03d756 Improve the realtime properties of USB transfers for embedded systems
like RPI-B and RPI-2.

Description of problem:
USB transfers can process data in their callbacks sometimes causing
unacceptable latency for other USB transfers. Separate BULK completion
callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give
BULK completion callbacks lesser execution priority than the
others. This way USB audio won't be interfered by heavy USB ethernet
usage for example.

Further serve USB transfer completion in a round robin fashion,
instead of only serving the most CPU hungry. This has been done by
adding a third flag to USB transfer queue structure which keeps track
of looping callbacks. The "command" callback function then decides
what to do when looping.

7ef5e8bc80 Better support memory mapped console devices, such as VGA and EFI
frame buffers and memory mapped UARTs.

1.  Delay calling cninit() until after pmap_bootstrap(). This makes
    sure we have PMAP initialized enough to add translations. Keep
    kdb_init() after cninit() so that we have console when we need
    to break into the debugger on boot.
2.  Unfortunately, the ATPIC code had be moved as well so as to
    avoid a spurious trap #30. The reason for which is not known
    at this time.
3.  In pmap_mapdev_attr(), when we need to map a device prior to the
    VM system being initialized, use virtual_avail as the KVA to map
    the device at. In particular, avoid using the direct map on amd64
    because we can't demote by virtue of not being able to allocate
    yet. Keep track of the translation.
    Re-use the translation after the VM has been initialized to not
    waste KVA and to satisfy the assumption in uart(4) that the handle
    returned for the low-level console is the same as later returned
    when the device is probed and attached.
4.  In pmap_unmapdev() remove the mapping from the table when called
    pre-init. Otherwise keep the mapping. During bus probe and attach
    device resources are mapped and unmapped multiple times, which
    would have us destroy the mapping used by the low-level console.
5.  In pmap_init(), set pmap_initialized to signal that we're not
    pre-init anymore. On amd64, bring the direct map in sync with the
    translations created at that time.
6.  Implement bus_space_map() and bus_space_unmap() for real: when
    the tag corresponds to memory space, call the corresponding
    pmap_mapdev() and pmap_unmapdev() functions to construct and
    actual handle.
7.  In efifb.c and vt_vga.c, remove the crutches and hacks and simply
    call pmap_mapdev_attr() or bus_space_map() as desired.

Notes:
1.  uart(4) already used bus_space_map() during low-level console
    setup but since serial ports have traditionally been I/O port
    based, the lack of a proper implementation for said function
    was not a problem. It has always supported memory mapped UARTs
    for low-level consoles by setting hw.uart.console accordingly.
2.  The use of the direct map on amd64 without setting caching
    attributes has been a bigger problem than previously thought.
    This change has the fortunate (and unexpected) side-effect of
    fixing various EFI frame buffer problems (though not all).

fac6a198c3 Correct the polarity of the PPS assert and clear events with respect to the
electrical signals on the serial port.  Virtually all devices which output a
PPS signal generate a brief higher-voltage pulse, the leading edge of which
is the on-time point.

Both DCD and CTS are active-low signals on the wire, meaning the assertion
of their status bits in the modem status register corresponds to the lower
voltage level on the wire.  So when the status bit transitions to not-set,
create a PPS assert event; when the status bit transitions to set, create a
PPS clear event.

196d3019a8 Allow the choice of PPS signal captured by uart(4) to be runtime-configured,
eliminating the need to build a custom kernel to use the CTS signal.

The historical UART_PPS_ON_CTS kernel option is still honored, but now it
can be overridden at runtime using a tunable to configure all uart devices
(hw.uart.pps_mode) or specific devices (dev.uart.#.pps_mode).  The per-
device config is both a tunable and a writable sysctl.

This syncs the PPS capabilities of uart(4) with the enhancements recently
recently added to ucom(4) for capturing from USB serial devices.

709c835a5a Disable 32-bit PIO for 6Gbit/s Intel SATA controllers.
For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA
ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine.
3Gbit/s ports on the same controllers have no this problem.

Workaround this by disabling 32-bit PIO for all Intel controllers that may
have 6Gbit/s ports.  It halves PIO performance from 6MB/s to 3MB/s, but
who bother about speed of such rare and slow mode, which is also highly
discouraged by SATA specifications?

79d2c5e857 Change KPI of how device drivers that provide wireless connectivity interact
with the net80211 stack.

Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.

Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:

- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
  the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
  driver about any changes: number of wlan(4) interfaces, number of them
  in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
  driver experiences errors and can not attribute them to any specific
  interface, driver updates ic_oerrors or ic_ierrors counters.

Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
  now provided by net.wlan.devices sysctl.

Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to Olivier Cochard, gjb@, mmoll@,
op@ and lev@, who also participated in testing. Details here:

https://wiki.freebsd.org/projects/ifnet/net80211

Still, drivers: ndis, wtap, mwl, ipw, bwn, wi, upgt, uath were not
tested. Changes to mwl, ipw, bwn, wi, upgt are trivial and chances
of problems are low. The wtap wasn't compilable even before this change.
But the ndis driver is complex, and it is likely to be broken with this
commit. Help with testing and debugging it is appreciated.

a046541623 Return the current ftdi bitbang mode with the UFTDIIOC_GET_BITMODE ioctl.
The ftdi chip itself has a "get bitmode" command that doesn't actually
return the current bitmode, just a snapshot of the gpio lines.  The chip
apparently has no way to provide the current bitmode.

This implements the functionality at the driver level.  The driver starts
out assuming the chip is in UART mode (which it will be, coming out of
reset) and keeps track of every successful set-bitmode operation so that
it can always return the current mode with UFTDIIOC_GET_BITMODE.

aaebf69062 Add support for Xen blkif indirect segment I/Os. This makes it possible for
the blkfront driver to perform I/Os of up to 2 MB, subject to support from
the blkback to which it is connected and the initiation of such large I/Os
by the rest of the kernel.  In practice, the I/O size is increased from 40 kB
to 128 kB.

The changes to xen/interface/io/blkif.h consist merely of merging updates
from the upstream Xen repository.

In dev/xen/blkfront/block.h we add some convenience macros and structure
fields used for indirect-page I/Os: The device records its negotiated limit
on the number of indirect pages used, while each I/O command structure gains
permanently allocated page(s) for indirect page references and the Xen grant
references for those pages.

In dev/xen/blkfront/blkfront.c we now check in xbd_queue_cb whether a request
is small enough to handle without an indirection page, and either follow the
previous behaviour or use new code for issuing an indirect segment I/O.  In
xbd_connect we read the size of indirect segment I/Os supported by the backend
and select the maximum size we will use; then allocate the pages and Xen grant
references for each I/O command structure.  In xbd_free those grants and pages
are released.

A new loader tunable, hw.xbd.xbd_enable_indirect, can be set to 0 in order to
disable this functionality; it works by pretending that the backend does not
support this feature.  Some backends exhibit a loss of performance with large
I/Os, so users may wish to test with and without this functionality enabled.
