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.

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.
- Fixed target discovery failures.
- Fixed mutual chap login 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.

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.

- 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.

Transition all boards that support arm cortex CPUs to armv7. This

This initial commit includes both base support for running ZCP scripts, and a

8552 ZFS LUA code uses floating point math
illumos/illumos-gate@916c8d8811916c8d8811https://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

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).

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.

In the case of running newvers.sh on a git tree w/o git-svn-id notes we

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.

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.

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).
New version is not compatible on supervisor mode with v1.9.1
(previous version).
Highlights:
o BBL (Berkeley Boot Loader) provides no initial page tables
anymore allowing us to choose VM, to build page tables manually
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).
