dfd9bc2a73 Tidy up comments and do some 80-column fixing. No functional changes. 2002-10-04 22:35:08 +00:00

8bdc70d040 As part of the effort to get RAIDframe playing nicely with LOCKDEBUG, 
rework how completed requests are handled.  In particular, instead of
doing all sorts of work and locking in interrupt context, completed
requests are now queued.  A new kernel thread (rf_RaidIOThread) now
handles calling rf_DiskIOComplete() and (req->CompleteFunc)() for each
completed request.  There is still work to be done to make RAIDframe
LOCKDEBUG friendly, but this change is a huge step forward.

9fbf5b5d27 Create a thread creation macro that make it easier to name the DAG process. 
Use it to have the DAGExecutionThread have a better name for each RAID
process ('raid0', 'raid1', etc., vs. just 'raid', 'raid', etc.)

0e45bff1d4 Since we are unlocking the lock before sleeping, there is no need 
to use ltsleep() when a tsleep() will suffice.  Makes RAIDframe+LOCKDEBUG
play together much better.

2b99f7cc34 Add a generic config finalization hook, to be called once all real 
devices have been discovered.  All finalizer routines are iteratively
invoked until all of them report that they have done no work.

Use this hook to fix a latent bug in RAIDframe autoconfiguration of
RAID sets exposed by the rework of SCSI device discovery.

instead use a string naming the driver.  The cfdriver is then looked

77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

813fbd6152 RF_LOCK_MUTEX()/RF_UNLOCK_MUTEX() often cover more code than they 
needs to.  In particular, they often surround calls to malloc().
Re-work the locking on most macros to avoid this problem.

XXX: On MP systems, simultaneous calls to the GET macros when a
freelist is empty may cause that freelist to grow more quickly than
before.  Given that the "increment" value of these lists are fairly
small, this shouldn't be too much of an issue.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

1aaf6772f1 - Add a mechanism for obtaining finer-grained 'progress' information 
regarding reconstructs, copybacks, etc.

- RAID 0 doesn't do copybacks, but don't make raidctl sweat about it.

26b4598736 Components which match on everything but the mod_counter are 
renegades, and must be handled correctly.  In particular, they should
be added to their old auto-config set, but then immediately released.
Failing to do otherwise means that they potentialy end up in a
different (and competing!) RAID set which may auto-configure in place
of the correct one, and cause all sorts of chaos at auto-configure
time.

e9b5b7aa5e Add a comment to clarify why we actually want the component label to 
be considered a 'match' even if the mod_counter is wrong.

d2b2ed0970 Checking parity re-write status makes no sense on RAID 0, but let's 
return something reasonable anyway.

071aed40ac A foolish consistency; most parts of the kernel use bp->b_data, so 
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.

c2e8f67477 Add some missing casts of ioctl arg. 
Obviously autoconfiguration wouldn't work on big-endian machines.

c71398f7a9 Don't allow configuration where the specified SectPerSU may result in IO larger 
than MAXPHYS being sent to underlying devices.  Addresses PR#9868.
Will change if/when MAXPHYS goes bye-bye.
