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
stable[2] mailing lists. Deprecation notices were added in e39ec8933b
and MFCd to stable branches.
Driver removals are being committed individually so that specific
drivers can be restored if necessary (either in FreeBSD or by downstream
projects).

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.

Prior to 9b6edf364e WITHOUT_KERNEL_SYMBOLS split kernel debug data
into standalone debug files at build time, but did not install those
files. As of 9b6edf364e it stopped splitting the debug data, leaving
it in the kernel and modules (the default kernel configs include
DEBUG=-g).
Revert 9b6edf364e and introduce a new build-time SPLIT_KERNEL_DEBUG
knob, as some people rely on the pre-9b6edf364eb0 WITHOUT_KERNEL_SYMBOLS
behaviour and that was imp's original intent.

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.
This interface already existed in the standalone out-of-tree
1.34.2 driver; this commit adds and enables it in the in-kernel
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.

Since 0b3178a45c we have added '-d' to the link command line for
kernel modules, so if any unexpected common symbols turn up (even though
we use -fno-common in CFLAGS), storage will be allocated in in the
module itself.
However, with lld this option did not have any effect since ~2017, and
as of lld 14 it warns: "-d, -dc, -dp, and --[no-]define-common will be
removed. See https://github.com/llvm/llvm-project/issues/53660"
Add a linker type and version check, to avoid adding the option for lld

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.

This dumper can instantiate and write the dump's contents to a
file-backed vnode.
Unlike existing disk or network dumpers, the vnode dumper should not be
invoked during a system panic, and therefore is not added to the global
dumper_configs list. Instead, the vnode dumper is constructed ad-hoc
when a live dump is requested using the new ioctl on /dev/mem. This is
similar in spirit to a kgdb session against the live system via
/dev/mem.
As described briefly in the mem(4) man page, live dumps are not
guaranteed to result in a usuable output file, but offer some debugging
value where forcefully panicing a system to dump its memory is not
desirable/feasible.
A future change to savecore(8) will add an option to save a live dump.

The ath driver has a lot of these warnings. It's an older driver, so
just supress these warnings until they can be fixed. They are a mix of
simple dead stores, debubgging output and stuff that would require
careful study to know if its safe to remove the access or not (there are
likely very few of the latter, but if there are any they are latent bugs
that compiler could optimize away). Since I have no ath hardware to test
on anymore, take the conservative approach.

The gunion(8) utility is used to track changes to a read-only disk on
a writable disk. Logically, a writable disk is placed over a read-only
disk. Write requests are intercepted and stored on the writable
disk. Read requests are first checked to see if they have been
written on the top (writable disk) and if found are returned. If
they have not been written on the top disk, then they are read from
the lower disk.
The gunion(8) utility can be especially useful if you have a large
disk with a corrupted filesystem that you are unsure of how to
repair. You can use gunion(8) to place another disk over the corrupted
disk and then attempt to repair the filesystem. If the repair fails,
you can revert all the changes in the upper disk and be back to the
unchanged state of the lower disk thus allowing you to try another
approach to repairing it. If the repair is successful you can commit
all the writes recorded on the top disk to the lower disk.
Another use of the gunion(8) utility is to try out upgrades to your
system. Place the upper disk over the disk holding your filesystem
that is to be upgraded and then run the upgrade on it. If it works,
commit it; if it fails, revert the upgrade.
Further details can be found in the gunion(8) manual page.

Boottrace is a facility for capturing trace events during boot and
shutdown. This includes kernel initialization, as well as rc. It has
been used by NetApp internally for several years, for catching and
diagnosing slow devices or subsystems. It is driven from userspace by
sysctl interface, and the output is a human-readable log of events
(kern.boottrace.log).
This commit adds the core boottrace functionality implementing these
interfaces. Adding the trace annotations themselves to kernel and
userland will happen in follow-up commits. A future commit will also add
a boottrace(4) man page.
For now, boottrace is unconditionally compiled into the kernel but
disabled by default. It can be enabled by setting the
kern.boottrace.enabled tunable to 1 in loader.conf(5).
There is an existing boot-time event tracing facility, which can be
compiled into the kernel with 'options TSLOG'. While there is some
functional overlap between this and boottrace, they are distinct. TSLOG
is suitable for generating detailed timing information and flamegraphs,
and has been used to great success by cperciva@ to diagnose and reduce
the overall system boot time. Boottrace aims to more quickly provide an
overview of timing and resource usage of the boot (and shutdown) process
to a sysadmin who requires this knowledge.
