a94a63f0a6 An MMC/SD/SDIO stack using CAM
Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.

Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items
have been overlooked.

a7dc31283a Remove the NATM framework including the en(4), fatm(4), hatm(4), and
patm(4) devices.

Maintaining an address family and framework has real costs when we make
infrastructure improvements.  In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.

Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021.  Improvements to the code in FreeBSD 11 are
certainly welcome.

72dec0792a - Add support for eMMC "partitions". Besides the user data area, i. e.
the default partition, eMMC v4.41 and later devices can additionally
  provide up to:
  1 enhanced user data area partition
  2 boot partitions
  1 RPMB (Replay Protected Memory Block) partition
  4 general purpose partitions (optionally with a enhanced or extended
    attribute)

  Of these "partitions", only the enhanced user data area one actually
  slices the user data area partition and, thus, gets handled with the
  help of geom_flashmap(4). The other types of partitions have address
  space independent from the default partition and need to be switched
  to via CMD6 (SWITCH), i. e. constitute a set of additional "disks".

  The second kind of these "partitions" doesn't fit that well into the
  design of mmc(4) and mmcsd(4). I've decided to let mmcsd(4) hook all
  of these "partitions" up as disk(9)'s (except for the RPMB partition
  as it didn't seem to make much sense to be able to put a file-system
  there and may require authentication; therefore, RPMB partitions are
  solely accessible via the newly added IOCTL interface currently; see
  also below). This approach for one resulted in cleaner code. Second,
  it retains the notion of mmcsd(4) children corresponding to a single
  physical device each. With the addition of some layering violations,
  it also would have been possible for mmc(4) to add separate mmcsd(4)
  instances with one disk each for all of these "partitions", however.
  Still, both mmc(4) and mmcsd(4) share some common code now e. g. for
  issuing CMD6, which has been factored out into mmc_subr.c.

  Besides simply subdividing eMMC devices, some Intel NUCs having UEFI
  code in the boot partitions etc., another use case for the partition
  support is the activation of pseudo-SLC mode, which manufacturers of
  eMMC chips typically associate with the enhanced user data area and/
  or the enhanced attribute of general purpose partitions.

  CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation.

- Now that properly issuing CMD6 is crucial (so data isn't written to
  the wrong partition for example), make a step into the direction of
  correctly handling the timeout for these commands in the MMC layer.
  Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as
  recommended by relevant specifications. However, quite some work is
  left to be done in this regard; all other R1B-type commands done by
  the MMC layer also should be followed by a SEND_STATUS (CMD13), the
  erase timeout calculations/handling as documented in specifications
  are entirely ignored so far, the MMC layer doesn't provide timeouts
  applicable up to the bridge drivers and at least sdhci(4) currently
  is hardcoding 1 s as timeout for all command types unconditionally.
  Let alone already available return codes often not being checked in
  the MMC layer ...

- Add an IOCTL interface to mmcsd(4); this is sufficiently compatible
  with Linux so that the GNU mmc-utils can be ported to and used with
  FreeBSD (note that due to the remaining deficiencies outlined above
  SANITIZE operations issued by/with `mmc` currently most likely will
  fail). These latter will be added to ports as sysutils/mmc-utils in
  a bit. Among others, the `mmc` tool of the GNU mmc-utils allows for
  partitioning eMMC devices (tested working).

- For devices following the eMMC specification v4.41 or later, year 0
  is 2013 rather than 1997; so correct this for assembling the device
  ID string properly.

- Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at
  least for some of the above a matching pair is required.

- In the ACPI front-end of sdhci(4) describe the Intel eMMC and SDXC
  controllers as such in order to match the PCI one.
  Additionally, in the entry for the 80860F14 SDXC controller remove
  the eMMC-only SDHCI_QUIRK_INTEL_POWER_UP_RESET.

168fce73b5 hyperv/vss: Add driver and tools for VSS
VSS stands for "Volume Shadow Copy Service".  Unlike virtual machine
snapshot, it only takes snapshot for the virtual disks, so both
filesystem and applications have to aware of it, and cooperate the
whole VSS process.

This driver exposes two device files to the userland:

    /dev/hv_fsvss_dev

    Normally userland programs should _not_ mess with this device file.
    It is currently used by the hv_vss_daemon(8), which freezes and
    thaws the filesystem.  NOTE: currently only UFS is supported, if
    the system mounts _any_ other filesystems, the hv_vss_daemon(8)
    will veto the VSS process.

    If hv_vss_daemon(8) was disabled, then this device file must be
    opened, and proper ioctls must be issued to keep the VSS working.

    /dev/hv_appvss_dev

    Userland application can opened this device file to receive the
    VSS freeze notification, hold the VSS for a while (mainly to flush
    application data to filesystem), release the VSS process, and
    receive the VSS thaw notification i.e. applications can run again.

    The VSS will still work, even if this device file is not opened.
    However, only filesystem consistency is promised, if this device
    file is not opened or is not operated properly.

hv_vss_daemon(8) is started by devd(8) by default.  It can be disabled
by editting /etc/devd/hyperv.conf.

0974f66d06 In order to allow mkimg(1) (and other tools) to become a build tool
that can be compiled on various OSes (including on older versions
of FreeBSD), make it possible to have it include the partitioning
scheme definitions without pulling in FreeBSD specifics.
In particular this means:
 o  move the scheme definitions iand related defines to header files
    under sys/disk,
 o  make them (more) portable by using uint#_t (where applicable)
    and renaming defines so that they at least have a good prefix,
 o  make the new headers stand-alone so that they don't need FreeBSD
    definitions, like struct uuid(*)
 o  keep the original headers for compatibility, but rewrite them to
    get the scheme definitions from <sys/disk/$scheme.h>.

(*) since UUID/GUID type definitions are non-portable and the GPT
scheme uses them, make it possible to have the scheme definitions
use an external type by allowing consumers of the header to set
GPT_UUID_TYPE. When GPT_UUID_TYPE has not been defined, the header
will use it's own type definition, which is the same as struct uuid.
The gpt_uuid_t typedef is created to abstract the details and allows
consumers to refer to a single type.

There is not conflict between the partitioning scheme headers and
what is defined in them. All headers can be included in the same
source files.

Note: consumers of the old headers have not been changed yet. Such
will be done if and when needed/beneficial.

9ea89f3223 WITH_META_MODE: Disable cookie handling for include installation.
Using a cookie with meta mode causes it to *not rerun* (as normal make
does) unless the command changes or filemon-detected files change.

After all of the work done here it turns out that skipping installation
is dangerous since the install commands use <dir>/*.h.  The actual build
command is not changing but the files installed are changing by the mere
act of adding a new header into the source tree.  Thus we cannot safely
use meta mode logic here.  It must always rerun and install the headers.
The install -C flag at least prevents churning timestamps when
installing a header that was already present.

8e8319a68d Stop building vers.c in include/ and only build the needed osreldate.h.
Because of how osreldate.h was being built with newvers.sh, which always
spat out a vers.c dependent on SVN or git, the meta mode build was
considering osreldate.h to depend on the current git or SVN index.  This
would lead to entire tree rebuilds when modifying git's index.  There's
no reason to be generating vers.c here so just skip it.

While here, in mk-osreldate.sh rename PARAM_H to proper PARAMFILE (which
newvers.sh already has a default for) and remove unneeded export.

3149cc9df6 HPET: create /dev/hpetN as a way to access HPET from userland.
In some cases, TSC is broken and special applications might benefit
from memory mapping HPET and reading the registers to count time.
Most often the main HPET counter is 32-bit only[1], so this only gives
the application a 300 second window based on the default HPET
interval.
Other applications, such as Intel's DPDK, expect /dev/hpet to be
present and use it to count time as well.

Although we have an almost userland version of gettimeofday() which
uses rdtsc in userland, it's not always possible to use it, depending
on how broken the multi-socket hardware is.

Install the acpi_hpet.h so that applications can use the HPET register
definitions.

[1] I haven't found a system where HPET's main counter uses more than
32 bit.  There seems to be a discrepancy in the Intel documentation
(claiming it's a 64-bit counter) and the actual implementation (a
32-bit counter in a 64-bit memory area).

fa0f6e62c6 Initial import of character device in userspace support for FreeBSD.
The CUSE library is a wrapper for the devfs kernel functionality which
is exposed through /dev/cuse . In order to function the CUSE kernel
code must either be enabled in the kernel configuration file or loaded
separately as a module. Currently none of the committed items are
connected to the default builds, except for installing the needed
header files. The CUSE code will be connected to the default world and
kernel builds in a follow-up commit.

The CUSE module was written by Hans Petter Selasky, somewhat inspired
by similar functionality found in FUSE. The CUSE library can be used
for many purposes. Currently CUSE is used when running Linux kernel
drivers in user-space, which need to create a character device node to
communicate with its applications. CUSE has full support for almost
all devfs functionality found in the kernel:
 - kevents
 - read
 - write
 - ioctl
 - poll
 - open
 - close
 - mmap
 - private per file handle data
