22dd228d5d Use a "rel" memory barrier for disowning the lock as it cames from an

0b0100db88 struct lock_instance and struct lock_list_entry don't need to be in the
public namespace for WITNESS as they are only used internally so just
move them in the private namespace for the subsystem (with all related
supporting definitions).

2946435299 Move i386 to generic RTC handling code.
Make clock_if.m and subr_rtc.c standard on i386

Add hints for "atrtc" driver, for non-PnP, non-ACPI systems.
NB: Make sure to install GENERIC.hints into /boot/device.hints in these!

Nuke MD inittodr(), resettodr() functions.

Don't attach to PHP0B00 in the "attimer" dummy driver any more, and remove
comments that no longer apply for that reason.

Add new "atrtc" device driver, which handles IBM PC AT Real Time
Clock compatible devices using subr_rtc and clock_if.

This driver is not entirely clean: other code still fondles the
hardware to get a statclock interrupt on non-ACPI timer systems.

Wrap some overly long lines.

After it has settled in -current, this will be ported to amd64.

Technically this is MFC'able, but I fail to see a good reason.

c9ad6040dd Emit summaries of struct c(alender)t(ime) <-> struct timespec conversions

Struct ct is used for setting/reading real time clocks and I'm about
to Do Things to some of those, so a bit of preemptive debugging is
in order.

031e0f3cd9 LK_NOWITNESS can be used now in lockmgr*() functions in order to skip

e5f94314ad - Re-introduce WITNESS support for lockmgr. About the old implementation
the only one difference is that lockmgr*() functions now accept
  LK_NOWITNESS flag which skips ordering for the instanced calling.
- Remove an unuseful stub in witness_checkorder() (because the above check
  doesn't allow ever happening) and allow witness_upgrade() to accept
  non-try operation too.

e058c00c40 Updates for changes in the way printf() handles hex floating point
numbers.
2008-04-12 03:11:56 +00:00
David Schultz
76303a9735 Make several changes to the way printf handles hex floating point (%a):
1. Previously, printing the number 1.0 could produce 0x1p+0, 0x2p-1,
   0x4p-2, or 0x8p-3, depending on what happened to be convenient. This
   meant that printing a value as a double and printing the same value
   as a long double could produce different (but equivalent) results.
   The change is to always make the leading digit a 1, unless the
   number is 0. This solves the aforementioned problem and has
   several other advantages.

2. Use the FPU to do rounding. This is far simpler and more portable
   than manipulating the bits, and it fixes an obsure round-to-even
   bug. It also raises the exceptions now required by IEEE 754R.
   The drawbacks are that it is usually slightly slower, and it makes
   printf less effective as a debugging tool when the FPU is hosed
   (e.g., due to a buggy softfloat implementation).

3. On i386, twiddle the rounding precision so that (2) works properly
   for long doubles.

4. Make several simplifications that are now possible due to (2).

5. Split __hldtoa() into a separate file.

b300d706ea - Use a lockmgr lock rather than a mtx to protect dirhash. This lock
may be held for the duration of the various dirhash operations which
   avoids many complex unlock/lock/revalidate sequences.
 - Permit shared locks on lookup.  To protect the ip->i_dirhash pointer we
   use the vnode interlock in the shared case.  Callers holding the
   exclusive vnode lock can run without fear of concurrent modification to
   i_dirhash.
 - Hold an exclusive dirhash lock when creating the dirhash structure for
   the first time or when re-creating a dirhash structure which has been
   recycled.

eb1314a249 - cache dp->i_offset in the local 'i_offset' variable for use in loop
indexes so directory lookup becomes shared lock safe.  In the modifying
   cases an exclusive lock is held here so the commit routine may
   rely on the state of i_offset.
 - Similarly handle i_diroff by fetching at the start and setting only once
   the operation is complete.  Without the exclusive lock these are only
   considered hints.
 - Assert that an exclusive lock is held when we're preparing for a commit
   routine.
 - Honor the lock type request from lookup instead of always using exclusive
   locking.

42b1030bbd Optimize package registration/deregistration. Previously, when looking up the
package name for the origin of a dependency, all entries in /var/db/pkg were
traversed for each dependency of added/removed package.  Now, gather all the
origins first, then do the lookup in a single pass over /var/db/pkg.

This should provide a major speedup for packages with hundreds of dependencies.

44b779b337 Identify ICH9 USB controllers.
I've taken a slightly different approach than is used with the ICH8 controllers
in that each controller is not identified individually (eg USB A, USB B, etc).
Instead I've given then same description to each one even though the device ID
differs.  This can easily be changed if desired, or ICH8 (and any others using
that approach) can be made to work as this does.

9b33b154b5 - Add the interrupt vector number to intr_event_create so MI code can
lookup hard interrupt events by number.  Ignore the irq# for soft intrs.
 - Add support to cpuset for binding hardware interrupts.  This has the
   side effect of binding any ithread associated with the hard interrupt.
   As per restrictions imposed by MD code we can only bind interrupts to
   a single cpu presently.  Interrupts can be 'unbound' by binding them
   to all cpus.

14320f1e7f Add a new flag, '-C' which enables a special mode that is intended for
catastrophic recovery.  Currently, this mode only validates whether a
cylindergroup has good signature data, and prompts the user to decide
whether to clear it as a whole.

This mode is useful when there is data damage on a disk and you are
working on copy of the original disk, as fsck_ffs(8) tends to abnormally
exit in such case, as a last resort to recover data from the disk.
