broken/fragile. Unlikely to be of much use, and confuses new users
when their system crashes when they, or their dhclient stumble over
it. See kern/10500, kern/8994 for the gory details.
* put #includes of opt headers and headers to get protos used by
net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.
* clean up uses to remove now-unnecessary header file inclusions, and
local prototypes of the fns.
* convert netisr dispatch implementations which didn't use
netisr_dispatch.h (pc532) to use it.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
such as the LM78 and VT82C686A (and eventually ACPI). Multiple
sensor devices can be hooked registered with `sysmon', and eventually
sysmon will also handle hardware (and software) watchdog timers.
Convert the `lm' and `viaenv' drivers to the new interface.
from devices connected to pckbc:
- Do actual sample collection in pckbc.
- Add rndsource_element_t to the slot data.
- Change pckbc_set_inputhandler() to take an additional argument,
the name of the device, which is (eventually) passed into
rnd_attach_source() to identify the source.
- Change callers of pckbc_set_inputhander() appropriately.
If __HAVE_CPU_TIMESTAMP is defined, <machine/rnd.h> exists and defines
two functions:
1) u_int32_t cpu_timestamp(void);
returns the 32 low order bits of a reasonably high frequency counter.
2) int cpu_havetimestamp(void);
returns non-zero if cpu_timestamp() actually works.
The timestamp counter should run at a frequency greater than 1 MHz
(otherwise, microtime would be sufficient); other than that, the exact
frequency and origin of the counter are unspecified.
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1(). In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.
This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.
- Add a second proc argument for inferior() since callers all had
curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()
state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.
- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.
Move count==-1 special handling from db_stack_trace_print() [nee

processor. Test against SONPROC as appropriate rather than
combinations of SRUN and curproc. Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.
pointer indicating how to print the symbol. This allows db_printsym()

While straightforward, apologies in advance if I've introduced any minor

platforms.

all the time (which crashes some vaios), get the static configuration,
and if config_search() finds a node, then do the dynamic configuration.
This seems to work fine on multiple vaios (which seem to crash
in different places...go figure).
Also, bring prototypes in-line with KNF and declare static as appropriate.
"#if 0" out pnpbios_getapmtable() and pnpbios_setnode() as they

Use manifest constants (PNP_CF_DEVCONF_DYNAMIC, etc.) in calls to

if you enable com*/lpt* at pnpbios0, to avoid attaching

contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

yet.. the keyboard controller actually has 2 PNPBIOS nodes (one to
represent the controller I/O resources and the kbd port IRQ, and one
for the aux port IRQ). To cope with this, we're attaching two instances
of the driver and forge on ahead once both nodes have been seen.
If someone has a better way, please feel free to step forward.
to be called `rl' and it conflict with RL vax disks, canonical and
historical unix driver name.
This changes are minimal: it only changes the name of RealTek driver.
The filename of source code and a lot of the letter `rl' in source
files should be changed shortly.
uvm_page_init() has completed, add a boolean uvm.page_init_done,
and test against that. Use this same boolean (rather than
pmap_initialized) in pmap_growkernel() to determine if we are
being called via uvm_page_init() to grow the kernel address space.
This fixes a problem on some i386 configurations where pmap_init()
itself was needing to have the kernel page table grown, and since
pmap_initialized was not yet set to TRUE, pmap_growkernel() was
choosing the wrong code path.
Fix tested by Havard Eidnes.
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
make them type-generic, which is necessary i.e. to operate on file offsets
without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
integral type (paddr_t, vaddr_t).

Some PCI soundcards don't seem to use the generic gameport function with
interface 0x10 used here, but have either an own BAR dedicated to this
(i.e. Sonic Vibes or ESS Solo-1) or specify their own device (see
PCI_PRODUCT_CREATIVELABS_SBJOY in sys/dev/pci/pcidevs.h).
Probably these use a similar simple sheme and adding a frontend for them would
be trivial, but I don't own any of these cards, so I didn't.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.

This makes it possible to create serial console dosboot.com's via uncommenting

enough info on this yet to fix it (c) a DPT HBA at an address usually
assigned to wdc0/1 may get detected as a WD100x controller. Some of them can
emulate a WD100x controller, but the one I tested with doesn't.

1. in pmap_steal_ptp(), don't trylock the pmap that wants a ptp,
the caller already has it locked.
2. do not panic in pmap_enter() due to memory allocation failures when
the PMAP_CANFAIL flag is given. to this end, move all such panics
from the lower-level routines to pmap_enter() and pmap_growkernel()
where we can check for this flag.
3. add #ifdef DIAGNOSTIC around all panics which are only reachable
if there's a bug or a hardware error.
