thorpej 05c6b5a9a0 - Add a B_ORDERED flag to communicate to drivers that an I/O request should 
be issued/completed in order; that is, provide a barrier for I/O queues.
- Change the buffer driver queue links to a TAILQ, rather than using
  a home-grown equivalent.  Provide BUFQ_*() macros to manipulate buffer
  queues; these deal with the barrier provided by B_ORDERED.
- Update disksort() accordingly, and provide 3 versions:
	- disksort_cylinder(): historical disksort(), which keys on
	  b_cylinder (and b_blkno for the case when b_cylinder matches).
	- disksort_blkno(): sorts only on b_blkno.  Essentially the
	  same as disksort_cylinder(), but with fewer comparisons.
	- disksort_tail(): requests are simply inserted into the queue
	  at the tail.  This is provided as an option so that drivers
	  can simply have a pointer to the appropriate sort function.
  Note that disksort() now pays attention to B_ORDERED.

mycroft e70f76146b Do file locking. 2000-01-21 19:56:07 +00:00
mycroft b714bb5102 Just call fflush() from _cleanup(), since it does the right locking. 2000-01-21 19:55:02 +00:00
mycroft f9b319ca18 Call __sclearerr(), nor clearerr(), so we don\`t try to double lock. 2000-01-21 19:54:13 +00:00
mycroft 0b24b6555f Do the lock *after* checking that the fp is valid. 2000-01-21 19:53:02 +00:00

mjacob eb5546b1cb add cdev_ses_init alias to cdev__oci_init 2000-01-21 17:52:29 +00:00
mycroft 482d37a470 Do the pthread errno hack. That is, *always* do: 
#define errno (*__errno())
This is necessary to make non-threaded libraries (e.g. libX11) continue to
work correctly when linked with -lpthread.  glibc also does this.
 2000-01-21 17:11:20 +00:00
mycroft f5d7100e26 Nuke `extern int errno;' in code we compile with -Wstrict-prototypes. We get 
the correct definition from errno.h.

pk 6b2ebb44a7 Move several PIL_* definitions into the scope of LOCORE stuff. 2000-01-21 13:22:55 +00:00
pk f8ac5484fa Medium sized code overhaul: 
* Improve communication between the `hard' and `soft' interrupt handlers
  to better distinguish various interrupt sources.
* Eliminate several race conditions where we would set a time out handler
  only after starting the command on the hardware.
* Handle most timeouts by resetting the controller; there isn't much chance
  of recovery in any other way.  Currently, the exception is a timeout
  on I/O, in which case we first try to pulse the controller's TC line
  in order to abort the pseudo-dma sequence.  Apparently, "normal"
  conditions can induce such a timeout when there's no disk in the drive.
* Reduce the formatting gap parameter to 0x54.
* On the obio bus, interpret the `status' attribute.
* Minimize console diagnostic output if the errors we get appear to be
  caused by the absence of a disk.

tsutsui 1bf52b391d rename (revert) memory disk filename /dev/mdX -> /dev/mdXa 2000-01-21 12:32:54 +00:00
tsutsui cac7cebd3e - rename (revert) normal memory disk device name /dev/mdX -> /dev/mdXa 
- now raw partitions are used for memory disk ioctls
 2000-01-21 12:28:22 +00:00
tsutsui a914ad6061 - use the raw partition for ioctl; `control device' is gone. 
- remove `sc_flags' member from md_softc
 - add check code whether the md device is configured in mdread/mdwrite

wrstuden 01dd896ae9 Fix tyop pointed out by Simon Burge. Also expand description 
a little, and change words to suggest overlay is a starting point for
layers which need to overlay the over-mounted fs.
