resource. Avoids useless interrupts occurring between the allocation
of the interrupt resource and the final initialisation of the
kernel. Cause of these interrupts is unknown (a resuming device?).
range attributes after they have been extracted from the master.
Hook up the i686 MP code to do this for each AP.
Be more careful about printing the default memory type for the i686.
Suggestions from: luoqi
- Try to unbreak what I broke by screwing with the tx queuing again.
I'm waiting for a few more people to test out this code and report back
before I move it into current. Hopefully it will be soon. Basically I
reverted to the old TX queuing strategy.
- Add experimental support for the 3c900B-FL (10mbps ST fiber). The card
should be detected properly and the 10baseFL mode supported, but again
I'm still waiting for word from a tester to see if this actually works.
It shouldn't affect the other cards though; all the differences are in
media selection.
- Set the TX start threshold register to get better performance.
- Increase the size of the RX and TX rings. UDP performance was pretty
bad because the TX ring was too small. Should be substantially better
now (I can saturate the link with either TCP or UDP now).
- Change some of the #defines to reflect proper 3Com ASIC names (boomerang,
cyclone, krakatoa, hurricane).
- Simplify and reorganize interrupt handler; ack all interrupts right
away and then process them. This avoids a potential race condition.
(Noted by Matt Dillon.)
- Reorganize the bridging code to eliminate using a goto to jump into
the middle of an if() {} clause. Sorry, that just made my brain itch.
- Use m_adj() in xl_rxeof().
- Make the payload alignment in xl_newbuf() the default (instead of
just conditionally defined for the alpha) to improve NFS performance
(avoids need for nfs_realign()).
This patch also moves the bogus comment (the comment is still not quite
right) and (as a side effect) removes some verbose initialisations (we
depend on static initialisation to 0 for almost everything in proc0).
The alpha kernels are bootable again. The change won't affect i386's
until machdep.c is changed.

In heavy-writing situations, QUEUE_LRU can contain a large number
of DELWRI buffers at its head. These buffers must be moved
to the tail if they cannot be written async in order to reduce
the scanning time required to skip past these buffers in later
getnewbuf() calls.

from ever catching up to the transmit consumer index. We can't let this
happen because ti_txeof() depends on the assumption that producer == consumer
means the ring is empty, and producer != consumer means the ring has some
number of active descriptors in it.
This will allow software teletext/intercast/subtitles decoding
while watching a TV station.
Based on code from Hiroki Mori <mori@infocity.co.jp> but reworked by
myself.
Add new #ifdef. By defining BKTR_NO_MSP_RESET you can prevent the
MSP34xx being reset by the bt848 driver. This is handy
if you pre-initialise the MSP34xx stereo audio chip in another
operating system first (eg MS Windows).

PV_TABLE_REF cleared before PV_TABLE_MOD, the page may get fault on read again.
On fault on write, pmap_emulate_reference mark the page dirty with
vm_page_dirty. That decrease ill effects of the bug.
The problem probably become more serious after my rev.1.18 a week ago.
This is a seriously beefed up chroot kind of thing. The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.
For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact: "real virtual servers".
Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.
Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.
It generally does what one would expect, but setting up a jail
still takes a little knowledge.
A few notes:
I have no scripts for setting up a jail, don't ask me for them.
The IP number should be an alias on one of the interfaces.
mount a /proc in each jail, it will make ps more useable.
/proc/<pid>/status tells the hostname of the prison for
jailed processes.
Quotas are only sensible if you have a mountpoint per prison.
There are no privisions for stopping resource-hogging.
Some "#ifdef INET" and similar may be missing (send patches!)
If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!
Tools, comments, patches & documentation most welcome.
Have fun...

that doesn't have it. This is achieved by having minimal do-nothing stubs
enabled when there are no bpfilter devices configured.
Driver modules should be built with BPF enabled for maximum
convenience (but can be built without it for maximum performance).
- %fs register is added to trapframe and saved/restored upon kernel entry/exit.
- Per-cpu pages are no longer mapped at the same virtual address.
- Each cpu now has a separate gdt selector table. A new segment selector
is added to point to per-cpu pages, per-cpu global variables are now
accessed through this new selector (%fs). The selectors in gdt table are
rearranged for cache line optimization.
- fask_vfork is now on as default for both UP and SMP.
- Some aio code cleanup.

3:
s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/
The remaining suser_xxx() calls will be scrutinized and dealt with
later.
There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.
More changes to the suser() API will come along with the "jail" code.
able to expand the zeros, ones etc masks on the fly. It seems a good
number of domains don't set the rn_maxkey variable anyway, and because
this is a domain itself, there is no guarantee we've been called after
a protocol that actually has set it (ie: inet), so start with a maxkey
of a relatively sane size as a base point until it can adapt on the fly.
it used to be that way. I'm not sure that it's needed, but it does
walk the ifp list..
Incidently, there's nothing to sanity check the ifq_maxlen on loaded
interfaces..
Get rid of the spl wrapper kludge, it doesn't seem to be needed between
init calls since all that's running is the domain/protocol timers and they
are safe since domain list modifications are splnet() protected (which
blocks the timers)
Conditionally compile 386-specific code.
pmap_enter:
Eliminate unnecessary TLB shootdowns.
pmap_zero_page and pmap_zero_page_area:
Use invltlb_1pg instead of duplicating the code.
was only looking at old style drivers in the pcidevice_set, which doesn't
exist any more.. Ultimately, the pci and eisa bus drivers will check for
hints for wiring, flags and enable/disable etc as well.
style pci drivers with a simple one-line change to use a module that
registers itself under new-bus and should in theory enable just about all
of the pci drivers to be loadable (kldload and loader(8)) but without
having the impact of converting the APIs yet.
This also fixes the problem of having undefined variables when only
new-style pci drivers are present.
conversion from short to unsigned long which is an argument of
bus_alloc_resource. Since the value -1 is used to indicate no port
reousece, id_port need to be signed (suggested by Doug Rabson and
Peter Wemm.)
Convert to new bus and bus dma.
Use latest PCI API.
bt_pci.c:
Fix a few bugs in how resourses are released left over from
when this driver was converted to new bus.
With these changes plus the egcs fix I committed a few minutes ago,
"make -DWANT_AOUT world" works again. Most likely, "make upgrade"
is fixed too, though I haven't tested that.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager. There is further room for optimizing
the interfaces still. All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.
1. Make read-ahead work for pread and aio_read.
2. Fix one place where a comparison of uio_offset with -1
wasn't updated to use FOF_OFFSET.
3. Honor O_APPEND in the FOF_OFFSET case.
In addition, use the variable name "ioflag" in both vn_read and
vn_write to avoid possible confusion between the variable "flag"
and the parameter "flags".

alpha/include/lock.h: remove nop simplelock macros, which are defined
in <sys/lock.h> if NCPUS == 1.
As a result, NULL_SIMPLELOCK is defined, and a few warnings removed.
2) rename variables to be more conclusive.
3) fix a problem in uhci_ii_done. Avoid collecting all the status's of the
TD's, we only need to one from the last inactive one.
4) Change the errorcount from 2 to 3 (see UHCI spec.).

Fixed problem with hanging while unmounting busy fs.
And (the most important) added some locks to prevent
simulaneous access to kernel structures!
- unifdef -DCOMPAT_IPFW (this was on by default already)
- remove traces of in-kernel ip_nat package, it was never committed.
- Make IPFW and DUMMYNET initialize themselves rather than depend on
compiled-in hooks in ip_init(). This means they initialize the same
way both in-kernel and as kld modules. (IPFW initializes now :-)
