b149eba475 Add note to UPDATING for ino64 to follow the standard upgrade process
The existing upgrade process documented in UPDATING is both necessary
and sufficient for upgrading across the ino64 change.  However, the
shortcut of installing both kernel + world before a single reboot has
been possible for quite some time, and several developers and users
were surprised by fallout from ino64.  Add an explicit entry pointing
out that the full process must be followed.

1bf5e133cb do not require binutils port when using lld as ld
r279908 added logic to Makefile.inc1 to automatically set
CROSS_BINUTILS_PREFIX for architectures not supported by the in-tree
binutils: arm64 when first introduced, and later riscv64 as well.

LLVM's LLD linker is now included in the base system, and is enabled by
default for arm64 and capable of linking world and kernel. Thus, avoid
automatically setting CROSS_BINUTILS_PREFIX and requiring the binutils
port if WITH_LLD_IS_LD is true.

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.

4026b44790 Fix buildworld for powerpc.
vmpage requires struct pmap to exist and contain a pm_stats field.  As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs.  Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct.  This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.

Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.

448897d366 add iic interface to ig4 driver, move isl and cyapa to iicbus
Summary:
The hardware does not expose a classic SMBus interface.
Instead it has a lower level interface that can express a far richer
I2C protocol than what smbus offers.  However, the interface does not
provide a way to explicitly generate the I2C stop and start conditions.
It's only possible to request that the stop condition is generated
after transferring the next byte in either direction.  So, at least
one data byte must always be transferred.
Thus, some I2C sequences are impossible to generate, e.g., an equivalent
of smbus quick command (<start>-<slave addr>-<r/w bit>-<stop>).

At the same time isl(4) and cyapa(4) are moved to iicbus and now they use
iicbus_transfer for communication.  Previously they used smbus_trans()
interface that is not defined by the SMBus protocol and was implemented
only by ig4(4).  In fact, that interface was impossible to implement
for the typical SMBus controllers like intpm(4) or ichsmb(4) where
a type of the SMBus command must be programmed.

The plan is to remove smbus_trans() and all its uses.
As an aside, the smbus_trans() method deviates from the standard,
but perhaps backwards, FreeBSD convention of using 8-bit slave
addresses (shifted by 1 bit to the left).  The method expects
7-bit addresses.

There is a user facing consequence of this change.
A user must now provide device hints for isl and cyapa that specify an iicbus to use
and a slave address on it.
On Chromebook hardware where isl and cyapa devices are commonly found
it is also possible to use a new chromebook_platform(4) driver that
automatically configures isl and cyapa devices.  There is no need to
provide the device hints in that case,

Right now smbus(4) driver tries to discover all slaves on the bus.
That is very dangerous.  Fortunately, the probing code uses smbus_trans()
to do its job, so it is really enabled for ig4 only.
The plan is to remove that auto-probing code and smbus_trans().

5ad05815a4 Document the unique requirements for upgrading more
prominently. Unlike in the past (dating back to the 4.x branch point),
you cannot upgrade from any point on the past couple of stable
branches to -current. Due to a bug in clang that existed before
r286035 in stable/9 or r286033 in stable/10, we cannot compile llvm
that's in 11.x or -current. Unfortunately, these revisions are after
9.3R and 10.3R on their respective branches. stable/11 and 11.0R are
not affected.

This also affects the upgrade path to 11 (including 11.0R) from
stable/9 and stable/10 (which would otherwise work, were it not for
this bug).

We also need to amend the 11.0R release notes.

bd79708dbf In the TCP stack, the hhook(9) framework provides hooks for kernel modules
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.

Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.

This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.

Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

583febf416 Strip leading spaces off of a SCSI disk's serial number
sys/cam/scsi/scsi_xpt.c
	Strip leading spaces off of a SCSI disk's reported serial number
	when populating the CAM serial number. This affects the output of
	"diskinfo -v" and the names of /dev/diskid/DISK-* device nodes,
	among other things.

	SPC5r05 says that the Product Serial Number field from the Unit
	Serial Number VPD page is right-aligned. So any leading spaces are
	not part of the actual serial number. Most devices don't left-pad
	their serial numbers, but some do. In particular, the SN VPD page
	that an LSI HBA emulates for a SATA drive contains enough
	left-padding to fill a 20-byte field.

UPDATING
	Add a note to UPDATING, because some users may have to update
	/etc/fstab or geom labels.

94098ab7c3 Remove brk and sbrk from arm64. They were defined in The Single UNIX
Specification, Version 2, but marked as legacy, and have been removed from
later specifications. After 12 years it is time to remove them from new
architectures when the main use for sbrk is an invalid method to attempt
to find how much memory has been allocated from malloc.

There are a few places in the tree that still call sbrk, however they are
not used on arm64. They will need to be fixed to cross build from arm64,
but these will be fixed in a follow up commit.

Old copies of binutils from ports called into sbrk, however this has been
fixed around 6 weeks ago. It is advised to update binutils on arm64 before
installing a world that includes this change.

da1b038af9 Use uintmax_t (typedef'd to rman_res_t type) for rman ranges.
On some architectures, u_long isn't large enough for resource definitions.
Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but
type `long' is only 32-bit.  This extends rman's resources to uintmax_t.  With
this change, any resource can feasibly be placed anywhere in physical memory
(within the constraints of the driver).

Why uintmax_t and not something machine dependent, or uint64_t?  Though it's
possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on
32-bit architectures.  64-bit architectures should have plenty of RAM to absorb
the increase on resource sizes if and when this occurs, and the number of
resources on memory-constrained systems should be sufficiently small as to not
pose a drastic overhead.  That being said, uintmax_t was chosen for source
clarity.  If it's specified as uint64_t, all printf()-like calls would either
need casts to uintmax_t, or be littered with PRI*64 macros.  Casts to uintmax_t
aren't horrible, but it would also bake into the API for
resource_list_print_type() either a hidden assumption that entries get cast to
uintmax_t for printing, or these calls would need the PRI*64 macros.  Since
source code is meant to be read more often than written, I chose the clearest
path of simply using uintmax_t.

Tested on a PowerPC p5020-based board, which places all device resources in
0xfxxxxxxxx, and has 8GB RAM.
Regression tested on qemu-system-i386

pxeboot in tftp loader mode (when built with LOADER_TFTP_SUPPORT) now

This allows to be able to use the traditional content /boot out of box. Meaning
it now works pretty much like all other loaders. It simplifies hosting hosting
multiple version of FreeBSD on a tftp server.

As a consequence, pxeboot does not look anymore for a pxeboot.4th (which was
never provided)

b67490a3b0 Fix errors being ignored in many phases of the build since the bmake integration.
Say it with me, "I will not chain commands with && in Makefiles"

This was originally fixed and explained quite well by bde@ in r36074.  The
initial bmake integration caused 'set -e' to stop being used which lead to
r252419.  Later 'set -e' expectations were fixed with bmake in r254980.

Because of the && here, errors would be ignored when building in parallel and
a dependency failed.  Such as bootstrap-tools since it builds everything in
parallel.  If any tool failed in obj/depend/all, it would just ignore the error
and continue to build.  This later would result in cascaded errors that only
confused the real issue.  This could also cause commands after the failed
command to still execute, leading to more confusion.

This should be fine if the command is in a sub-shell such as: (cmd1 && cmd2)

This reverts r252419.

56585ab576 Rework the 'make -n -n' feature such that '-n' recurses and '-N' does not.
Bmake has a documented feature of '-N' to skip executing commands which is
specifically intended for debugging top-level builds and not recursing into
sub-directories.  This matches the older 'make -n' behavior we added which made
'-n -n' the recursing target and '-n' a non-recursing target.

Removing the '-n -n' feature allows the build to work as documented in
the bmake manpage with '-n' and '-N'.  The older '-n -n' feature was also
not documented anywhere that I could see.

Note that the ${_+_} var is still needed as currently bmake incorrectly
executes '+' commands when '-N' is specified.

The '-n' and '-n -n' features were broken for several reasons prior to this.
r251748 made '_+_' never expand with '-n -n' which resulted in many
sub-directories not being visited until fixed 2 years later in r288391, and
many targets were given .MAKE over the past few years which resulted in
non-sub-make commands, such as rm and ln and mtree, to be executed.

This should also allow removing some indirection hacks in bsd.subdir.mk and
other cases of .USE that have a .MAKE by using '+'.

In addition, change kernel debug file extension to .debug, to match
userland debug files.

When using the supported kernel installation method the
/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
as is done with /boot/kernel.

Developers wishing to maintain the historical behavior of installing
debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).

d1b06863fb Huge cleanup of random(4) code.
* GENERAL
- Update copyright.
- Make kernel options for RANDOM_YARROW and RANDOM_DUMMY. Set
  neither to ON, which means we want Fortuna
- If there is no 'device random' in the kernel, there will be NO
  random(4) device in the kernel, and the KERN_ARND sysctl will
  return nothing. With RANDOM_DUMMY there will be a random(4) that
  always blocks.
- Repair kern.arandom (KERN_ARND sysctl). The old version went
  through arc4random(9) and was a bit weird.
- Adjust arc4random stirring a bit - the existing code looks a little
  suspect.
- Fix the nasty pre- and post-read overloading by providing explictit
  functions to do these tasks.
- Redo read_random(9) so as to duplicate random(4)'s read internals.
  This makes it a first-class citizen rather than a hack.
- Move stuff out of locked regions when it does not need to be
  there.
- Trim RANDOM_DEBUG printfs. Some are excess to requirement, some
  behind boot verbose.
- Use SYSINIT to sequence the startup.
- Fix init/deinit sysctl stuff.
- Make relevant sysctls also tunables.
- Add different harvesting "styles" to allow for different requirements
  (direct, queue, fast).
- Add harvesting of FFS atime events. This needs to be checked for
  weighing down the FS code.
- Add harvesting of slab allocator events. This needs to be checked for
  weighing down the allocator code.
- Fix the random(9) manpage.
- Loadable modules are not present for now. These will be re-engineered
  when the dust settles.
- Use macros for locks.
- Fix comments.

* src/share/man/...
- Update the man pages.

* src/etc/...
- The startup/shutdown work is done in D2924.

* src/UPDATING
- Add UPDATING announcement.

* src/sys/dev/random/build.sh
- Add copyright.
- Add libz for unit tests.

* src/sys/dev/random/dummy.c
- Remove; no longer needed. Functionality incorporated into randomdev.*.

* live_entropy_sources.c live_entropy_sources.h
- Remove; content moved.
- move content to randomdev.[ch] and optimise.

* src/sys/dev/random/random_adaptors.c src/sys/dev/random/random_adaptors.h
- Remove; plugability is no longer used. Compile-time algorithm
  selection is the way to go.

* src/sys/dev/random/random_harvestq.c src/sys/dev/random/random_harvestq.h
- Add early (re)boot-time randomness caching.

* src/sys/dev/random/randomdev_soft.c src/sys/dev/random/randomdev_soft.h
- Remove; no longer needed.

* src/sys/dev/random/uint128.h
- Provide a fake uint128_t; if a real one ever arrived, we can use
  that instead. All that is needed here is N=0, N++, N==0, and some
  localised trickery is used to manufacture a 128-bit 0ULLL.

* src/sys/dev/random/unit_test.c src/sys/dev/random/unit_test.h
- Improve unit tests; previously the testing human needed clairvoyance;
  now the test will do a basic check of compressibility. Clairvoyant
  talent is still a good idea.
- This is still a long way off a proper unit test.

* src/sys/dev/random/fortuna.c src/sys/dev/random/fortuna.h
- Improve messy union to just uint128_t.
- Remove unneeded 'static struct fortuna_start_cache'.
- Tighten up up arithmetic.
- Provide a method to allow eternal junk to be introduced; harden
  it against blatant by compress/hashing.
- Assert that locks are held correctly.
- Fix the nasty pre- and post-read overloading by providing explictit
  functions to do these tasks.
- Turn into self-sufficient module (no longer requires randomdev_soft.[ch])

* src/sys/dev/random/yarrow.c src/sys/dev/random/yarrow.h
- Improve messy union to just uint128_t.
- Remove unneeded 'staic struct start_cache'.
- Tighten up up arithmetic.
- Provide a method to allow eternal junk to be introduced; harden
  it against blatant by compress/hashing.
- Assert that locks are held correctly.
- Fix the nasty pre- and post-read overloading by providing explictit
  functions to do these tasks.
- Turn into self-sufficient module (no longer requires randomdev_soft.[ch])
- Fix some magic numbers elsewhere used as FAST and SLOW.

5b03aba6c8 Switch TI platform support code from using FreeBSD's custom-baked DTS
files to vendor-provided ones. It should make easier to adopt platform
code to new revisions of hardware and to use DTS overlays for various
Beaglebone extensions (shields/capes).

Original dts filenames were not changed, they're now wrappers over dts
files provided by TI. So make sure you update .dtb files on your
devices as part of kernel update

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3

On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt
on serial port in multiuser mode. Single user mode serial console
should work as-is

vt(4) is a new console driver which brings features such as:
    o  Support for Unicode and double-width characters
    o  Integration with the KMS kernel video drivers
    o  Support for UEFI

You may need to update your console settings in /etc/rc.conf, most
probably the keymap. During boot, /etc/rc.d/syscons will indicate what
you need to do.

vt(4) still has issues and lacks some features compared to syscons(4).
See the wiki for up-to-date information:
    https://wiki.freebsd.org/Newcons

If you want to keep using syscons(4), you can do so by adding the
following line to /boot/loader.conf:

user-visible behavior and will require updates to the xorg-server port
on PowerPC when using ATI graphics cards.

0aafd404f8 Add compat shims for XDEV and XDEV_ARCH so we don't break all the
users of them. Also, add a note to updating. We'll keep these shims at
least until the 12 branch.

8a833bda0a The GNU readline library is now an INTERNALLIB - that is, it is
statically linked into consumers (GDB and variants) in the base
system, and the shared library is no longer installed.

That also allows ports to be able to use a modern version of readline

50f73640ba Remove ia64 from the list of known architectures and add an entry to
UPDATING. This is the first step towards the removal of ia64 from
head. A buildworld for ia64 will now yield:

% make buildworld
make[1]: "/usr/src/Makefile.inc1" line 151: Unknown target ia64:ia64.

While here, trim the ia64-specific additions from ObsoleteFiles.inc

824a909300 Rename the WITHOUT_VT_SUPPORT knob to WITHOUT_VT
The _SUPPORT knobs have a consistent meaning which differs from the
behaviour controlled by this knob.  As the knob is opt-out and has not
appeared in a release the impact should be low.

1cb207df04 Change suggestion how to set MAKESYSPATH as broken incremental build
workaround. Magic ".../share/mk" (search directories up to /)
does not work for f.e. /usr/src/gnu/lib/libgcc because the path
inside is starting from /usr/obj hierarchy and ends up in
/usr/share/mk, not in the /usr/src/share/mk where src.opts.mk is.
IMHO proper fixing of incremental build is needed urgently.

8c7ec47a40 Move atf-sh from /usr/bin/ to /usr/libexec/
In r266650, we made libatf-c and libatf-c++ private libraries so that no
components outside of the source tree could unintendedly depend on them.

This change does the same for the "atf-sh library" by moving the atf-sh
interpreter from its public location in /usr/bin/ to the private location
in /usr/libexec/.  Our build system will ensure that our own test programs
use the right binary, but users won't be able to depend on atf-sh by
"mistake".

Committing this now to ride the UPDATING notice added with r267172 today.

727a7ce81b Homogenize libatf-* version numbers with upstream.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected.  This is just confusing and bound to cause
problems down the road.

Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default.  However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.
