thorpej f7c9b87381 Update for sys/buf.h/disksort_*() changes, plus make it compilable on 
more systems.
 2000-01-21 23:41:45 +00:00
thorpej dc59bc1db3 Update for sys/buf.h/disksort_*() changes. 2000-01-21 23:39:55 +00:00
thorpej 52242fdf9f Update for sys/buf.h/disksort_*() changes. 2000-01-21 23:28:59 +00:00
thorpej 0ef111e8ee - Implement bowrite() -- perform an asynchronous, ordered write. 2000-01-21 23:22:24 +00:00
thorpej e3d3905ac7 Preserve B_ORDERED. 2000-01-21 23:21:46 +00:00
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.

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.

cjs b54595a488 Make sure that everything in GENERIC is in ALPHA, and that the two files 
have config lines in the same order to make diffing easier.

danw 6c14ba0dba Fill in the alignment trap handler a bit: now it can fix unaligned 
floating point loads and stores (to work around a gcc bug), but will
still cause a bus error on other sorts of unaligned accesses.
