time-of-day clocks, ported from NetBSD. The front-ends are expected
to be at least partly machine-dependent; the sparc64 EBus and SBus
ones will be commited to MD directories for now (in a subsequent commit).
a set of helper routines to deal with real-time clocks. The generic
functions access the clock diver using a kobj interface. This is intended
to reduce code reduplication and make it easy to support more than one
clock model on a single architecture.
This code is currently only used on sparc64, but it is planned to convert
the code of the other architectures to it later.
I have not been able to find very much information about the PC98
extended partition layout so this is gleaned from the source in
our pc98 architecture. Corrections and patched very welcome.

The detection code in this method is written so that it should work on
all architectures which means that you can plug a Sun disk into a i386
now and access the partitions.
We still need an endian-agnostic ufs/ffs before this is really
interresting, but the main focus was to get sparc64 onto the GEOM
trail.
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.
- move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
- call power_profile_set_state() also from APM driver when AC-line
status changes
- add call-back function for Crusoe LongRun controlling on power
profile changes for a example
buffer length, determine if the pointer is to a valid string. Currently,
the only check is whether a '\0' appears in the buffer. This is useful
when pulling in a structure from userland that may contain one or more
strings, and validity testing must be performed on elements of the
structure. When copying normal string arguments, copyinstr() is
expected to be used.

hw.midi.debug and hw.midi.seq.debug to 1 to enable debug log.
- Make debug messages human-frendly.
- Implement /dev/music.
- Add a timer engine required by /dev/music.
- Fix nonblocking I/O.
- Fix the numbering of midi and synth devices.
Remove the explicit call to aio_proc_rundown() from exit1(), instead AIO
will use at_exit(9).
Add functions at_exec(9), rm_at_exec(9) which function nearly the
same as at_exec(9) and rm_at_exec(9), these functions are called
on behalf of modules at the time of execve(2) after the image
activator has run.
Use a modified version of tegge's suggestion via at_exec(9) to close
an exploitable race in AIO.
Fix SYSCALL_MODULE_HELPER such that it's archetecuterally neutral,
the problem was that one had to pass it a paramater indicating the
number of arguments which were actually the number of "int". Fix
it by using an inline version of the AS macro against the syscall
arguments. (AS should be available globally but we'll get to that
later.)
Add a primative system for dynamically adding kqueue ops, it's really
not as sophisticated as it should be, but I'll discuss with jlemon when
he's around.
cardbus in the kernel, not on all the bridges that implement it.
Note: this is NEWCARD only, so we don't want it for the 'card' case,
unlike card_if.m, which is both NEWCARD and OLDCARD.
- Add S4BIOS sleep implementation. This will works well if MIB
hw.acpi.s4bios is set (and of course BIOS supports it and hibernation
is enabled correctly).
- Add DSDT overriding support which is submitted by takawata originally.
If loader tunable acpi_dsdt_load="YES" and DSDT file is set to
acpi_dsdt_name (default DSDT file name is /boot/acpi_dsdt.aml),
ACPI CA core loads DSDT from given file rather than BIOS memory block.
DSDT file can be generated by iasl in ports/devel/acpicatools/.
- Add new files so that we can add our proposed additional code to Intel
ACPI CA into these files temporary. They will be removed when
similar code is added into ACPI CA officially.
"[...] and removes the hostcache code from standard kernels---the
code that depends on it is not going to happen any time soon,
I'm afraid."
Time to clean up.
- Now that apm loadable module can inform its existence to other kernel
components (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
- Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
- Add simple arbitration mechanism for APM vs. ACPI. This prevents
the kernel enables both of them.
- Remove obsolete `#ifdef DEV_APM' related code.
- Add abstracted interface for Powermanagement operations. Public apm(4)
functions, such as apm_suspend(), should be replaced new interfaces.
Currently only power_pm_suspend (successor of apm_suspend) is implemented.

Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".
ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.
TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.
