2ec1dc3639 Add function OF_decode_addr(). This function obtains the physical
address of the device identified by its phandle_t by traversing OFW's
device tree. The space and address returned by this function can
subsequently be passed to sparc64_fake_bustag() to construct a valid
tag and handle for use by the newbus I/O functions.

Use of this function is expected to be limited to pre-newbus access to
devices, such as consoles and keyboards.

497c334767 Simplify the ioctl handling in GEOM.
This replaces the current ioctl processing with a direct call path
from geom_dev() where the ioctl arrives (from SPECFS) to any directly
connected GEOM class.

The inverse of the above is no longer supported.  This is the
situation were you have one or more intervening GEOM classes, for
instance a BSDlabel on top of a MBR or PC98.  If you want to issue
MBR or PC98 specific ioctls, you will need to issue them on a MBR
or PC98 providers.

This paves the way for inviting CD's, FD's and other special cases
inside GEOM.

f02e8e8122 Use pmap_steal_memory() for the msgbuf instead of trying to squeeze
it in the last chunk (phys_avail block). The last chunk very often is
not larger than one or two pages, resulting in a msgbuf that's too
small to hold a complete verbose boot.
Note that pmap_steal_memory() will bzero the memory it "allocates".
Consequently, ia64 will never preserve previous msgbufs. This is not
a noticable difference in practice. If the msgbuf could be reused,
it was invariably too small to have anything preserved anyway.

3390d47670 Implement MBUF_STRESS_TEST mark II.
Changes from the original implementation:

- Fragmentation is handled by the function m_fragment, which can
be called from whereever fragmentation is needed.  Note that this
function is wrapped in #ifdef MBUF_STRESS_TEST to discourage non-testing
use.

- m_fragment works slightly differently from the old fragmentation
code in that it allocates a seperate mbuf cluster for each fragment.
This defeats dma_map_load_mbuf/buffer's feature of coalescing adjacent
fragments.  While that is a nice feature in practice, it nerfed the
usefulness of mbuf_stress_test.

- Add two modes of random fragmentation.  Chains with fragments all of
the same random length and chains with fragments that are each uniquely
random in length may now be requested.

b9651df42c o interlock domain list when adding domains
o remove irrlevant spl

Notes:

1. We don't lock domain list traversals as this is safe until we start
   removing domains.
2. The calculation of max_datalen in net_init_domain appears safe as
   noone depends on max_hdr and max_datalen having consistent values.
3. Giant is still held for fast and slow timeouts; this must stay until
   each timeout routine is properly locked (coming soon).

d919a11d06 - Define a new flag for getblk(): GB_NOCREAT. This flag causes getblk() to

a0ebaaddef - Don't acquire the vnode interlock in drain_output(). Instead, require the
caller to acquire it.  This permits drain_output() to be done atomically
   with other operations as well as reducing the number of lock operations.
 - Assert that the proper locks are held in drain_output().
 - Change getdirtybuf() to accept a mutex as an argument.  This mutex is used
   to protect the vnode's buf list and the BKGRDWAIT flag.  This lock is
   dropped when we successfully acquire a buffer and held on return
   otherwise.  These semantics reduce the number of cumbersome cases in
   calling code.
 - Pass the mtx from getdirtybuf() into interlocked_sleep() and allow this
   mutex to be used as the interlock argument to BUF_LOCK() in the LOCKBUF
   case of interlocked_sleep().
 - Change the return value of getdirtybuf() to be the resulting locked buffer
   or NULL otherwise.  This is for callers who pass in a list head that
   requires a lock.  It is necessary since the lock that protects the list
   head must be dropped in getdirtybuf() so that we don't have a lock order
   reversal with the buf queues lock in bremfree().
 - Adjust all callers of getdirtybuf() to match the new semantics.
 - Add a comment in indir_trunc() that points at unlocked access to a buf.
   This may also be one of the last instances of incore() in the tree.

b21a0008ba Introduce MAP_ENTRY_GROWS_DOWN and MAP_ENTRY_GROWS_UP to allow for
growable (stack) entries that not only grow down, but also grow up.
Have vm_map_growstack() take these flags into account when growing
an entry.

This is the first step in adding support for upward growable stacks.
It is a required feature on ia64 to support the register stack (or
rstack as I like to call it -- it also means reverse stack). We do
not currently create rstacks, so the upward growing is not exercised
and the change should be a functional no-op.

411d10a600 Migrate the sf_buf allocator that is used by sendfile(2) and zero-copy
sockets into machine-dependent files.  The rationale for this
migration is illustrated by the modified amd64 allocator.  It uses the
amd64's direct map to avoid emphemeral mappings in the kernel's
address space.  On an SMP, the emphemeral mappings result in an IPI
for TLB shootdown for each transmitted page.  Yuck.

Maintainers of other 64-bit platforms with direct maps should be able
to use the amd64 allocator as a reference implementation.

 - Don't use the B_LOCKED flag and QUEUE_LOCKED for background write

   write buffer.
 - Remove the B_LOCKED flag and the locked buffer queue.  They are no longer
   used.
 - The vnode interlock is used around checks for BKGRDINPROG where it may
   not be strictly necessary.  If we hold the buf lock the a back-ground
   write will not be started without our knowledge, one may only be
   completed while we're not looking.  Rather than remove the code, Document
   two of the places where this extra locking is done.  A pass should be

7abc12de03 - In LCK_BUF() simply change the owner of the buf to the kernel.
- In ULCK_BUF we no longer need to acquire the lock, just write the buf out.
 - The combination of these changes eliminates one more use of B_LOCKED which
   is in the way of making the buffer cache SMP safe.  In the long term
   ext2fs should probably not try to optimize the use of their metadata bufs
   with a private cache.  This will starve the rest of the system for buffers
   in the extreme case.

1855be730c Revision 1.126 broke the interface of the bktr driver's
METEORSSIGNAL ioctl.  Applications use this ioctl with the value
METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery,
but revision 1.126 caused the driver to return EINVAL in this case.
Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses
0 to reset signal delivery.

This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the
bktr driver, and restructures the code a bit so that it is otherwise
identical between the bktr and meteor drivers.

5fdbb0d222 This is a major rework of the ATA driver (ATAng)
Restructure the way ATA/ATAPI commands are processed, use a common
ata_request structure for both. This centralises the way requests
are handled so locking is much easier to handle.

The driver is now layered much more cleanly to seperate the lowlevel
HW access so it can be tailored to specific controllers without touching
the upper layers. This is needed to support some of the newer
semi-intelligent ATA controllers showing up.

The top level drivers (disk, ATAPI devices) are more or less still
the same with just corrections to use the new interface.

Pull ATA out from under Gaint now that locking can be done in a sane way.

Add support for a the National Geode SC1100. Thanks to Soekris engineering
for sponsoring a Soekris 4801 to make this support.

Fixed alot of small bugs in the chipset code for various chips now
we are around in that corner anyways.

3f51411974 Allow bus barrier operations on fake tags. The purpose of a fake

Since barriers are a fundamental part of bus space accesses, not
allowing them on fake tags would defeat the purpose of these tags.
We use the barrier function normally associated with nexus. This
is the barrier used when subordinates haven't defined a barrier
themselves.

53e655ce37 Check in the known good version of the wi driver, with prism/symbol
support stripped out and minimally renamed to owi.  This driver
attaches to lucent cards only.  This is designed to aid in the testing
of fixes to the wi driver for lucent cards.  It is supported only as a
module (you cannot compile it into your kernel).  You cannot have the
wi driver in your kernel (or loaded as a moudle) to use the owi
module.

I've not connected it to build, as this module is currently for
debugging purposes.  This is for developers only at the present time.
If we can't get lucent support fixed by 5.2 code freeze, then we'll
re-evaulate this support level.  Please use this to fix the lucent
support in dev/wi.  This will be removed from the system when lucent
support has been fixed in dev/wi.

Note to developers: Do not connect this to the build, make it possible
to build into the kernel or otherwise 'integrate' this into system
without checking with me first.  This is for debugging purposes only.

If this doesn't work for you, I don't want to hear about it unless you
are fixing the wi driver :-)

6817cec98e - Remember to flip the foreground and background color attributes in
gfb_draw if 'flip' is specified.  This causes the mouse cut region
  to be displayed in reverse color so it is visbile.
- Use the "other" implementation of gfb_cursor for the creator driver,
  which doesn't assume there is a hardware cursor.  It seems that the
  hardware cursor that creator provides doesn't display the character
  under the cursor in reverse colors, so the driver does this manually
  and uses the hardware cursor for the mouse pointer (which it also works
  much better for).  This is wedged here because it required less hoops
  than accessing the syscons vtb from inside the video driver, which is
  needed to read the character and color attributes under the new cursor
  position.

functions are used so text mode is very fast.

e51fe8759d Rewrite the code that uses the try/catch paradigm implemented by
goto and abstracted by the itry, ithrow and icatch macros (among
others). The problem with this code is that it doesn't compile on
ia64. The compiler is sufficiently confused that it inserts a call
to __ia64_save_stack_nonlock(). This is a magic function that saves
enough of the stack to allow for non-local gotos, such as would be
the case for nested functions. Since it's not a compiler defined
function, it needs a runtime implementation. This we have not in a
standalone compilation as is the kernel.

There's no indication that the compiler is not confused on other
platforms. It's likely that saving the stack in those cases is
trivial enough that the compiler doesn't need to off-load the
complexity to a runtime function.

The code is believed to be correctly translated, but has not been
tested. The overall structure remained the same, except that it's
made explicit. The macros that implement the try/catch construct
have been removed to avoid reintroduction of their use. It's not
a good idea.

In general the rewritten code is slightly more optimal in that it
doesn't need as much stack space and generally is smaller in size.

The functions in ia64-bitops.h merely call panic() for now. They need
to be implemented some day, just not today.

9539d5b4f6 Remove PAGE_SIZE_4K, PAGE_SIZE_8K and PAGE_SIZE_16K and replace them
with LOG2_PAGE_SIZE. A single option is better to LINT than multiple
mutual exclusive ones.

6ff26c064f Picking PAGE_SHIFT as a global option is a bad idea. Instead call the
option LOG2_PAGE_SIZE.

c639ca93f4 Initial sweep at dividing up the generic 32bit-on-64bit kernel support
from the ia32 specific stuff.  Some of this still needs to move to the MI
freebsd32 area, and some needs to move to the MD area.  This is still
work-in-progress.

f199109fcd Begin attempting to consolidate the two different i386 emulations
on ia64 and amd64.  I'm attempting to keep the generic 32bit-on-64bit
binary support seperate from the i386 support and the MD backend support.

49dc7ac17d Use the requested page's object field instead of the vnode's. In some
cases, the vnode's object field is not initialized leading to a NULL
pointer dereference when the object is locked.

72c5c840ff Add the DA_Q_NO_PREVENT quirk which keeps da(4) from sending PREVENT/ALLOW
commands.  Add a quirk for the Creative Nomad MuVo USB device that uses
it as well as NO_SYNCHRONIZE_CACHE.

tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

2b6e83104c Correct typo introduced during manual merge: hook up the reflect_tcp
test to the reflect_tcp entry point, rather than the reflect_icmp
entry point.
