Changes since 1.26.6.0 are listed here. This list comes from the
Release Notes for "Chelsio Unified Wire 3.17.0.0 for Linux" dated
2022-07-29.
Fixes
-----
BASE:
- Enabled all MA parity interrupt bits.
- Use config file value to override number of rx channel. nrxch=1 was not
handled in the firmware.
- Replaced read only registers with new registers EDC_H_BIST_USER_WDATA0,
EDC_H_BIST_USER_WDATA1 and EDC_H_BIST_CMD_LEN to dump the uP memory parity
error status registers.
- 10G simplex module support enabled.

Currently, subr_bus.c shares logic for (a) maintaining all HW devices
(e.g. discovery/attach/detach logic) and (b) generic devctl notification
layer for devices/PMU/GEOM/interfaces/etc).
These two subsystems share really tiny interaction interface, composed of 3
notification functions. With that in mind, move devctl layer to a
separate file, establishing a clear notification interface between the
sub.c bus layer and the provider (devctl).
The primary driver of this change is netlink implementation (D36002).
The idea is to propagate device-level events to netlink as well, so all
netlink customers can subscribe to these changes.
The long-term goal is to deprecate devctl and to use netlink as the
kernel<> userland transport provided netlink gets enough traction.

This change adds public KPI to work with routes using pre-created
nexthops, instead of using data from addrinfo structures. These
functions will be later used for adding/deleting kernel-originated
routes and upcoming netlink protocol.
As a part of providing this KPI, low-level route addition code has been
reworked to provide more control over route creation or change.
Specifically, a number of operation flags
(RTM_F_<CREATE|EXCL|REPLACE|APPEND>) have been added, defining the
desired behaviour the the route already exists (or not exists). This
change required some changes in the multipath addition code, resulting
in moving this code to route_ctl.c, rendering mpath_ctl.c empty.

Generally, access to the kernel debugger is considered to be unsafe from
a security perspective since it presents an unrestricted interface to
inspect or modify the system state, including sensitive data such as
signing keys.
However, having some access to debugger functionality on production
systems may be useful in determining the cause of a panic or hang.
Therefore, it is desirable to have an optional policy which allows
limited use of ddb(4) while disabling the functionality which could
reveal system secrets.
This loadable MAC module allows for the use of some ddb(4) commands
while preventing the execution of others. The commands have been broadly
grouped into three categories:
- Those which are 'safe' and will not emit sensitive data (e.g. trace).
Generally, these commands are deterministic and don't accept
arguments.
- Those which are definitively unsafe (e.g. examine <addr>, search
<addr> <value>)
- Commands which may be safe to execute depending on the arguments
provided (e.g. show thread <addr>).
Safe commands have been flagged as such with the DB_CMD_MEMSAFE flag.
Commands requiring extra validation can provide a function to do so.
For example, 'show thread <addr>' can be used as long as addr can be
checked against the system's list of process structures.
The policy also prevents debugger backends other than ddb(4) from
executing, for example gdb(4).

Add three simple hooks to the debugger allowing for a loaded MAC policy
to intervene if desired:
1. Before invoking the kdb backend
2. Before ddb command registration
3. Before ddb command execution
We extend struct db_command with a private pointer and two flag bits
reserved for policy use.

Add an option to enable/disable DTrace without disabling ZFS. New
architectures such as CHERI may support ZFS before they support DTrace
and the old model of WITHOUT_CDDL disabling both wasn't helpful.
For compatiblity, the CDDL option remains and WITHOUT_CDDL implies
WITHOUT_DTRACE. WITHOUT_DTRACE also implies WITHOUT_CTF.
As part of this change, largely convert cddl/*/Makefile to using the
more compact SUBDIR.${MK_<FOO>}+= form rather than using intermediate

Split the current FDT-only implementation up into an FDT and an
ACPI part reusing and sharing as much code as possible (thanks mw!).
This makes the Synopsis XHCI root hubs attach correctly on SolidRun's
HoenyComb instead of just the generic XHCI root and this means we
are also doing proper chip setup and applying the quirk needed there [1].
There is one problem with ACPI attachment in that it uses the generic
XHCI PNP ID. So we need to do extra checks in order to not claim
all xhci, which means we check for a known quirk to be present
in acpi_probe. Long term this isn't scaling and this was discussed
in SolidRun's Discord Channel in 2021 with the intend that "jnettlet"
will take this to a steering committee. Since then ACPI has kind-of
become a technology non grata (due to not getting changes into Linux
timely) so it is unclear if this will ever happen. If there will be
further hardware with dwc3/ACPI we should go and make sure this problem
gets solved.

The two implementations for the pca9548 switch and the pca9547 mux
seemed close enough so we can put them together and with a bit more
abstraction add pca9540 support.
While here apply a bit of consistency in variable and driver naming and
use device_has_property instead of the FDT-only OF_ variant.
This disconnects pca9547 from the build but does not yet delete it.

Along with the snd_sb8 and snd_sb16 drivers. They supported ISA
Creative Sound Blaster and compatible sound cards.
Note that isa/sb.h is not removed, as it is still used by some PCI
sound card drivers.
ISA sound card drivers are deprecated as discussed on the current[1] and

Driver removals are being committed individually so that specific
drivers can be restored if necessary (either in FreeBSD or by downstream

Commit acfb506b3d replaced an exit 0 when using -V with a return
instead. FreeBSD's sh treats a return outside of a function like
exit, but this is a non-portable extension. Other Bourne shells only
permit return to be used within a function and continue execution
(possibly with a warning).
To fix, don't reuse VARS_ONLY (which is intended to be set by other
scripts before sourcing newvers.sh directly) and instead use a new
variable (VARS_ONLY_EXIT) to restore the use of exit for the
non-sourced case.

DEBUG=-g).

This allows the "irdma" driver to communicate with the ice(4)
driver to allow it access to the underlying device's hardware
resources as well as synchronize access to shared resources.

driver.
Note:
Adds hack to module Makefile to compile interface/.m files
These are required for the RDMA client interface, but they don't
build as-is like the normal .c files. The source directory doesn't
seem to be included by default, so add lines that specifically
add them as libraries so that ice_rdma.h can be found and the
interface files will compile.

When FreeBSD is running as dom0 (initial domain) on a Xen system it
has access to the native ACPI tables and is the OSPM. However the
hypervisor is the entity in charge of the CPU idle and frequency
states, and in order to perform this duty it requires information
found the ACPI dynamic tables that can only be parsed by the OSPM.
Introduce a new Xen specific ACPI driver to fetch the Processor
related information and upload it to Xen. Note that this driver needs
to take precedence over the generic ACPI CPU driver when running as
dom0, so downgrade the probe score of the native driver to
BUS_PROBE_DEFAULT in order for the Xen specific driver to use
BUS_PROBE_SPECIFIC.
Tested on an Intel NUC to successfully parse and upload both the Cx and
Px states to Xen.
