d8371cb18e Remove CPU_HAVEFPU.
Instead, use a runtime decision to handle COP1 traps.  If floating point
support is present in the current CPU, enable saving of the floating point
state.  If support is not present, fail with SIGILL.

7a158e826d Support the EFI Runtime Services on arm64. As with amd64 we use the 1:1
mapping. This uses the new common code shared with amd64.

The RTC should only be accessed via EFI. There is no locking around it as
the spec only has this as a requirement for the PC-AT CMOS device.

714d3ee05b cxgbe(4): Update T6, T5, and T4 firmwares to 1.16.63.0.
Changes since 1.16.26.0 for all three firmwares are listed below.  This
list was obtained from the Release Notes of the Chelsio Unified Wire
v3.5.05 release for Linux.

T6 Firmware

================================================================================
Version : 1.16.63.0
Date    : 09/29/2017
================================================================================

Fixes
-----

BASE:
- Fixed a fw crash when configured traffic rate limit is less than 10kbps.
- Fixed traffic rate limiting for smaller traffic rate value.

ETH:
- Fixed 40G link failure when interface is toggled.
- Fixed adapter crash when interface is toggled during traffic.
- Fixed 25G link failure when PEER only supports consortium mode autoneg
  for 25G.
- Fixed 100G optics link failure when cable is plugged in after bringing up
  the interface.
- Enable RS FEC as default if speed is 100G.
- Fixed DCBX configuration refresh failure.

OFLD
- Fixed 0B iWARP ingress read failure.
- Fixed iWARP SRQ reuse failure.

FOiSCSI:
- Fixed vlan interface ping failure.

================================================================================
Version : 1.16.59.0
Date    : 09/05/2017
================================================================================

FIXES
-----

BASE:
- Fixed fw crash caused by MC parity error in SO adapters.
- Generate Timer0Int interrupt if fw crashes due to unaligned access error. Host
  driver must look into PCIE_FW register to see if any fw fatal error has
  encountered. If PCIE_FW doesn't indicate any error then driver must ignore this
  interrupt.
- Fixed receive buffer threshold settings which was resulting in error frames on
  receive side.

ETH:
- Fixed an issue in connection traffic shaping when
  FLOWC_WR->FW_FLOWC_MNEM_SCHEDCLASS is not received in first WR on the connection.
- Fixed link failure when speed is changed from 10G-1G-10G due to incorrect flag
  check.
- Fixed improper LED behaviour for blink test and when traffic is running.
- Removed storage of previous fec settings from fw. Driver needs to pass the user
  settings whenever a new module is plugged in as fw resets these when a module is
  unplugged.

OFLD
- OVS offload: TP cache is flushed periodically to get the accuate filters stats
  (hit count).

ENHANCEMENTS
------------

BASE:
- Ring backbone feature added. New FW_PARAMS_PARAM_DEV_RING_BACKBONE param type
  added to query and enable ring backbone support.
- VNI support added for filtering. New entry_type FW_VI_MAC_TYPE_EXACTMAC_VNI
  added to FW_VI_MAC_CMD.
- Added new API FW_PARAM_PARAM_DEV_MPSBGMAP to read the priority to buffer group
  mapping for the ports.
- FW_PARAMS_PARAM_DEV_TPCHMAP API added to read the port to channel mapping.
- HMA (Host memory access) support added. New FW_HMA_CMD and
  FW_PARAMS_PARAM_DEV_HMA_SIZE added to query and configure the HMA. It
  enables the memfree support (256 connections) for iwarp.
- PTP support enabled.

ETH:
- Added consortium mode 50G support.
- Added the ability to allow only selected speeds to be advertised during auto
  negotiation.
- Increased port capability from 16 to 32 bits to support more speeds.
  FW_PARAMS_PARAM_PFVF_PORT_CAPS32 added to query whether fw supports 16 or 32
  bit port capability.

OFLD:
- RDMA Write with immediate support added (iwarp 2.0 feature)
- FW_TLS_KEYCTX_TX_WR removed and security key management moved to driver.
- 256 offloaded connections support for iwarp on SO adapters.

iSCSI:
- New param FW_PARAMS_PARAM_DEV_PPOD_EDRAM added for iscsi ppod configuration
  in EDRAM (performance improvement).

FOiSCSI:
- iSCSI Command offload target support added.

FOFCoE:
- FCoE support enabled.

094fc1ed0f Tag all armv7 kernels as such in their machine config line.
Transition all boards that support arm cortex CPUs to armv7. This
leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835
which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup
around the time RPI-B went in. Copy std.armv6 to std.armv7, even
though that duplicates a lot of stuff. More work needs to be done to
sort out the duplication.

float isn't supported by the the in-tree gcc, so it hasn't been

  ZFS channel programs (ZCP) adds support for performing compound ZFS
  administrative actions via Lua scripts in a sandboxed environment (with time
  and memory limits).
  This initial commit includes both base support for running ZCP scripts, and a
  small initial library of API calls which support getting properties and

  Testing: in addition to the included unit tests, channel programs have been in

illumos/illumos-gate@916c8d8811
916c8d8811

https://www.illumos.org/issues/8552
  In the LUA interpreter used by "zfs program", the lua format() function
  accidentally includes support for '%f' and friends, which can cause compilation
  problems when building on platforms that don't support floating-point math in
  the kernel (e.g. sparc). Support for '%f' friends (%f %e %E %g %G) should be
  removed, since there's no way to supply a floating-point value anyway (all
  numbers in ZFS LUA are int64_t's).

fe182ba1d0 aesni(4): Add support for x86 SHA intrinsics
Some x86 class CPUs have accelerated intrinsics for SHA1 and SHA256.
Provide this functionality on CPUs that support it.

This implements CRYPTO_SHA1, CRYPTO_SHA1_HMAC, and CRYPTO_SHA2_256_HMAC.

Correctness: The cryptotest.py suite in tests/sys/opencrypto has been
enhanced to verify SHA1 and SHA256 HMAC using standard NIST test vectors.
The test passes on this driver.  Additionally, jhb's cryptocheck tool has
been used to compare various random inputs against OpenSSL.  This test also
passes.

Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni:      SHA1: ~8300 Mb/s    SHA256: ~8000 Mb/s
cryptosoft:       ~1800 Mb/s    SHA256: ~1800 Mb/s

So ~4.4-4.6x speedup depending on algorithm choice.  This is consistent with
the results the Linux folks saw for 4kB buffers.

The driver borrows SHA update code from sys/crypto sha1 and sha256.  The
intrinsic step function comes from Intel under a 3-clause BSDL.[0]  The
intel_sha_extensions_sha<foo>_intrinsic.c files were renamed and lightly
modified (added const, resolved a warning or two; included the sha_sse
header to declare the functions).

bcf2b954c3 Add support for handling undefined instructions in userspace and the
kernel. We can register callbacks to perform the required operation on the
saved registers before returning.

This is initially used to work around a bug in old versions of QEMU that
trigger such an exception when reading from an ID register when it should
load z zero value.

I expect this could be used with other exception types, e.g. to emulate
special register access from userland.

This prevents incorrect subversion revision detection when "git svn" is
not being used to get the sources but git is available. Previously old
subversion revisions included in commit messages were favoured over the
more recent and correct revisions in git notes.

For example cf1f35574722 represents r315395 but was treated as r313908
which is referenced in the commit message. Commits following
r315395/cf1f35574722 but before another commit with a git-svn-id
reference in the commit message would be treated as r313908 as well.

ed9652da5f Add NTB driver for PLX/Avago/Broadcom PCIe switches.
This driver supports both NTB-to-NTB and NTB-to-Root Port modes (though
the second with predictable complications on hot-plug and reboot events).
I tested it with PEX 8717 and PEX 8733 chips, but expect it should work
with many other compatible ones too.  It supports up to two NT bridges
per chip, each of which can have up to 2 64-bit or 4 32-bit memory windows,
6 or 12 scratchpad registers and 16 doorbells.  There are also 4 DMA engines
in those chips, but they are not yet supported.

While there, rename Intel NTB driver from generic ntb_hw(4) to more specific
ntb_hw_intel(4), so now it is on par with this new ntb_hw_plx(4) driver and
alike to Linux naming.

495947bcfa newvers.sh: accommodate git worktree
newvers.sh looks for a .vcs subdirectory (e.g. .git, .svn) to determine
which vcs info tool to run (e.g., git rev-parse, svn info).

(As of r308789 if a .vcs subdirectory is not found at ${TOPDIR} then
newvers.sh walks up successive parent directories, testing for the .vcs
subdirectory at each step.  This is done in case the FreeBSD source is
built in a subdirectory as part of some larger project, but either way
newvers.sh still tests for the .vcs subdirectory.)

However, when using git worktree there is no .git subdirectory but
rather a plain text .git file which contains a reference to the main
working tree.

Change findvcs() to test that the .vcs entry exists, regardless of type.

bb2e8108e1 Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.
This driver supports only basic timekeeping functionality.  It completely
replaces the ds133x driver.  It can also replace the ds1374 driver, but that
will take a few other changes in MIPS code and config, and will be committed
separately.  It does NOT replace the existing ds1307 driver, which provides
access to some of the extended features on the 1307 chip, such as controlling
the square wave output signal.  If both ds1307 and ds13rtc drivers are
present, the ds1307 driver will outbid and win control of the device.

This driver can be configured with FDT data, or by using hints on non-FDT
systems.  In addition to the standard hints for i2c devices, it requires
a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
(i.e., the same format as FDT compat strings).

      and enable MMU in S-mode.
    o SBI interface changed.
    o GENERIC kernel.
      FDT is now chosen standard for RISC-V hardware description.
      DTB is now provided by Spike (golden model simulator). This
      allows us to introduce GENERIC kernel. However, description
      for console and timer devices is not provided in DTB, so move
      these devices temporary to nexus bus.
    o Supervisor can't access userspace by default. Solution is to
      set SUM (permit Supervisor User Memory access) bit in sstatus
      register.
    o Compressed extension is now turned on by default.
    o External GCC 7.1 compiler used.
    o _gp renamed to __global_pointer$
    o Compiler -march= string is now in use allowing us to choose
      required extensions (compressed, FPU, atomic, etc).

be improved in-tree more easily than out of tree and shouldn't gate

53e0bebaca enable --build-id for the kernel link
A Build-ID is an identifier generated at link time to uniquely identify
ELF binaries.  It allows efficient confirmation that an executable or
shared library and a corresponding standalone debuginfo file match.
(Otherwise, a checksum of the debuginfo file must be calculated when
opening it in a debugger.)

The FreeBSD base system includes GNU bfd ld 2.17.50 as the linker for
architectures other than arm64.  Build-ID support was added to bfd ld
shortly after that version, so was not previously available to us.

We can now start making use of Build-ID as we migrate to using lld or
bfd ld from ports, conditionally enabled based on the LINKER_TYPE and
LINKER_VERSION make variables added in r320244 and subsequent commits.

210ecc0021 Rework logic for skipping .depend/.meta file read/stat/writes.
- Rename _SKIP_READ_DEPEND to _SKIP_DEPEND since it also avoids writing.
- This now uses .NOMETA to avoid reading any .meta files related to
  DEPENDOBJS.  Objects not in OBJS/DEPENDOBJS may still have their .meta
  files read in if they are in the dependency graph.
- This also avoids statting .meta and .depend files in the META_MODE +
  -DNO_FILEMON case.

5964294736 add -znotext to kernel module link invocation
ARM kernel modules require .text relocations (DT_TEXTREL) in shared
object ouptut, which is not allowed by default by lld.  Add the -znotext
option to enable this.  For simplicity add it unconditionally: it is
already default and thus either redundant (GNU BFD ld and gold from
ports) or ignored as an unknown option (GNU BFD ld 2.17.50 in the base
system).

f9cdbaba8d MFV r318946: 8021 ARC buf data scatter-ization
illumos/illumos-gate@770499e185
770499e185

https://www.illumos.org/issues/8021
  The ARC buf data project (known simply as "ABD" since its genesis in the ZoL
  community) changes the way the ARC allocates `b_pdata` memory from using linear
  `void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This
  improves ZFS's performance by helping to defragment the address space occupied
  by the ARC, in particular for cases where compressed ARC is enabled. It could
  also ease future work to allocate pages directly from `segkpm` for minimal-
  overhead memory allocations, bypassing the `kmem` subsystem.
  This is essentially the same change as the one which recently landed in ZFS on
  Linux, although they made some platform-specific changes while adapting this
  work to their codebase:
  1. Implemented the equivalent of the `segkpm` suggestion for future work
  mentioned above to bypass issues that they've had with the Linux kernel memory
  allocator.
  2. Changed the internal representation of the ABD's scatter/gather list so it
  could be used to pass I/O directly into Linux block device drivers. (This
  feature is not available in the illumos block device interface yet.)

FreeBSD notes:
- the actual (default) chunk size is 4KB (despite the text above saying 1KB)
- we can try to reimplement ABDs, so that they are not permanently
  mapped into the KVA unless explicitly requested, especially on
  platforms with scarce KVA
- we can try to use unmapped I/O and avoid intermediate allocation of a
  linear, virtual memory mapped buffer
- we can try to avoid extra data copying by referring to chunks / pages
  in the original ABD

d23db91ef4 ext2fs: Add uninit_bg feature support.
From the linux tune2fs(8) manpage:
"Allow the kernel to initialize bitmaps and inode tables and keep a high
watermark for the unused inodes in a filesystem, to reduce e2fsck(8) time.
This first e2fsck run after enabling this feature will take the full time,
but subsequent e2fsck runs will take only a fraction of the original time,
depending on how full the file system is."

5274cd55d5 Create a new option ARM_USE_V6_BUSDMA to force an armv4/5 kernel to
use the armv6 busdma interface. This interface uses more memory than
the armv4 one, but bounces more data more often so may be more correct
than the armv4 one. It is intended for debugging purposes only at the

This patch contains a new driver for the network unit of Marvell
Armada 38x/XP SoCs, called NETA. This support was thoroughly tested
and optimised in terms of stability and performance. Additional
hardware features, like Buffer Management (BM) or Parser and Classifier
(PnC) will be progressively supported as needed.

system retrieve its config data from the fdt data.

The properties that are common to all phys are decoded and returned in a
structure.  The fdt node handles for the mac and phy devices are also
returned in the config data struct, so a driver can easily obtain additional
hardware-specific config values from the fdt data.

465659643b Augment wait queue support in the LinuxKPI.
In particular:
- Don't evaluate event conditions with a sleepqueue lock held, since such
  code may attempt to acquire arbitrary locks.
- Fix the return value for wait_event_interruptible() in the case that the
  wait is interrupted by a signal.
- Implement wait_on_bit_timeout() and wait_on_atomic_t().
- Implement some functions used to test for pending signals.
- Implement a number of wait_event_*() variants and unify the existing
  implementations.
- Unify the mechanism used by wait_event_*() and schedule() to put the
  calling thread to sleep.

This is required to support updated DRM drivers. Thanks to hselasky for
finding and fixing a number of bugs in the original revision.

40373cf5b8 Remove msdosfs -o large support.
Its purpose was to translate the values for msdosfs inode numbers,
which is calculated from the msdosfs structures describing the file,
into the range representable by 32bit ino_t.  The translation acted
for filesystems larger than 128Gb, it reserved the range 0xf0000000
(FILENO_FIRST_DYN) to UINT32_MAX and remembered some arbitrary
translation of ino >= FILENO_FIRST_DYN into this range.  It consumed
memory that could be only freed by unmount, and the translation was
not stable across remounts.

With ino_t type extended to 64 bit, there is no such issue and values
can be returned without compaction to 32bit.  That is, for the native
environments, the translation layer is not necessary and adds
significant undeserved code complexity.  For compat ABIs which use
32bit ino_t, the vfs.ino64_trunc_error sysctl provides some measures
to soften the failure mode when inode numbers truncation is not safe.

dc6a41b936 Add the infrastructure to support loading multiple versions of TCP
stack modules.

It adds support for mangling symbols exported by a module by prepending
a string to them. (This avoids overlapping symbols in the kernel linker.)

It allows the use of a macro as the module name in the DECLARE_MACRO()
and MACRO_VERSION() macros.

It allows the code to register stack aliases (e.g. both a generic name
["default"] and version-specific name ["default_10_3p1"]).

With these changes, it is trivial to compile TCP stack modules with
the name defined in the Makefile and to load multiple versions of the
same stack simultaneously. This functionality can be used to enable
side-by-side testing of an old and new version of the same TCP stack.
It also could support upgrading the TCP stack without a reboot.
