2593e9dcb2 Add support for extended descriptor format to Altera mSGDMA driver.
The format to use depends on hardware configuration (synthesis-time),
so make it compile-time kernel option.

Extended format allows DMA engine to operate with 64-bit memory addresses.

c363b16c63 sys: Remove DEV_RANDOM device option
Remove 'device random' from kernel configurations that reference it (most).
Replace perhaps mistaken 'nodevice random' in two MIPS configs with 'options
RANDOM_LOADABLE' instead.  Document removal in UPDATING; update NOTES and
random.4.

251a32b5b2 tun/tap: merge and rename to tuntap
tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).

This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp

[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).

ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.

(MFC commentary)

This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.

I have no plans to do this MFC as of now.

3782136ff1 random(4): Restore availability tradeoff prior to r346250
As discussed in that commit message, it is a dangerous default.  But the
safe default causes enough pain on a variety of platforms that for now,
restore the prior default.

Some of this is self-induced pain we should/could do better about; for
example, programmatic CI systems and VM managers should introduce entropy
from the host for individual VM instances.  This is considered a future work
item.

On modern x86 and Power9 systems, this may be wholly unnecessary after
D19928 lands (even in the non-ideal case where early /boot/entropy is
unavailable), because they have fast hardware random sources available early
in boot.  But D19928 is not yet landed and we have a host of architectures
which do not provide fast random sources.

This change adds several tunables and diagnostic sysctls, documented
thoroughly in UPDATING and sys/dev/random/random_infra.c.

e8643b01e6 Modularize xz.
Embedded lzma decompression library becomes a module usable by other
consumers, in addition to geom_uzip.

Most important code changes are
- removal of XZ_DEC_SINGLE define, we need the code to work
  with XZ_DEC_DYNALLOC;
- xz_crc32_init() call is removed from geom_uzip, xz module handles
  initialization on its own.

xz is no longer embedded into geom_uzip, instead the depend line for
the module is provided, and corresponding kernel option is added to
each MIPS kernel config file using geom_uzip.

The commit also carries unrelated cleanup by removing excess "device geom_uzip"
in places which were missed in r344479.

96744f0225 Make ZSTD a real option via ZSTDIO.
It looks like the intent was to allow ZSTD support to be
compiled into the kernel with options ZSTDIO. But it doesn't look
like that was ever implemented or I'm missing how to do it.

I did a cursory audit of kernel config files and made a decision to
enable ZSTDIO in riscv GENERIC and mips MALTA configurations.  All other
kernel configurations already had this option in their kernel configs
but they didn't do anything useful as the feature was declared as
"standard" prior to this.

is now unobtanium. It's only had API changes in the last 7 years, and

lot of code that reimplements base FreeBSD functionality, diminishing
the chances it still works. Without hardware to teset it on, or
prospects of obtaining such hardware and without vendor support, it's

ada611f6ad Retire old ADM 5120 port. It never grew much beyond the original port.
It came into the tree with the project/mips merge 8 years ago. At the
time, it was hard to find a board with enough RAM to run. Now FreeBSD
requires at least 2x the RAM it did then. No changes have happened to
this port apart from API churn and license tagging since then. It ran
OK at the time it was committed, but no sightings in the wild have
happened since shortly after it was committed.

https://www.linux-mips.org/wiki/Adm5120_devices lists a bunch of
boards that were available 5 years ago (but are no longer
available). The beefiest one had only 64MB of RAM which is too
small. The Mirktik RB1xx never had more than 32MB.

Also remove confusing QEMU config file that never ever worked in QEMU
for mips. MALTA is used for that. Another of my past mistakes, false
starts that never amounted to anything.
