christos | fix the function pointer and callback mess:
- callback functions return 0 and their result is not checked; make them void.
- there are two types of callbacks and they used to overload their parameters
and the callback structure; separate them into "function" and "value"
callbacks.
- make the wait function signature consistent.

mrg | convert the main raidPtr mutex to a kmutex, and add a couple of cv's to
cover the old sleep/wakeup points for adding_hot_spare and waitForReconCond.
convert all remaining simple_lock's to kmutexes (they're not used or compiled
right now... even with all options enabled) and remove the support for them.
this leaves just a pair of tsleep()/wakeup() calls using old scheduling APIs.
|
| 1.45 |
| 02-May-2011 |
mrg | use a unique wchan identifier for node_queue_cv than the old default.
|
| 1.44 |
| 27-Apr-2011 |
mrg | prepare to convert more raidframe old lock/sleep APIs to mutex/condvar:
- remove RF_DECLARE_EXTERN_MUTEX and RF_DECLARE_STATIC_MUTEX, the qualifier
can be provided at the use point with the normal define
- rename the *LGMGR_MUTEX() macros to *mutex2() names, and add some more
defines for use:
rf_declare_mutex2()
rf_declare_cond2()
rf_lock_mutex2()
rf_unlock_mutex2()
rf_init_mutex2()
rf_destroy_mutex2()
rf_init_cond2()
rf_destroy_cond2()
rf_wait_cond2()
rf_signal_cond2()
rf_broadcast_cond2()
- use the new names for the configureMutex(), which previous used some combo
of direct mutex* calls and macros
- convert the node_queue to use a mutex/cv combo
- in rf_ShutdownEngine() and DAGExecutionThread(), also signal the former from
the latter when it is done and about to exit
- convert iodone_lock to use the new macros
|
| 1.43 |
| 23-Apr-2011 |
mrg | move the iodone setup and tear down into rf_engine.c. this fixes
"raidctl -u" and should also help the case where we fail to setup
a device part of the way through.
|
| 1.42 |
| 23-Apr-2011 |
mrg | convert the iodone_lock to a mutex, and use a condvar for signalling.
this only handles the smallest use of old simple_lock/tsleep/wakeup
APIs inside raidframe, and it points out that cv(9)'s have only one
wait channel per cv, whereas each tsleep() caller can specify a
different wait channel. this change removes the difference between
normal raidio and waiting for IO during shutdown.
i've tested this one 3 systems, ran atf, and had mlelstv and rmind
review the change.

Finally commit the RAIDframe parity map Summer Of Code project.
Drastically reduces the amount of time spent rewriting parity after an
unclean shutdown by keeping better track of which regions might have had
outstanding writes. Enabled by default; can be disabled on a per-set
basis, or tuned, with the new raidctl(8) commands.
Discussed on tech-kern@ to a general air of approval; exhortations to
commit from mrg@, christos@, and others.
Thanks to Google for their sponsorship, oster@ for mentoring the
project, assorted developers for trying very hard to break it, and
probably more I'm forgetting.

oster | Re-work the handling of incoming I/O in RAIDframe:
- introduce rf_buf_queue_check() which checks to see if there
is work to do in the incoming buffer queue
- rf_RaidIOThread() is now responsible for calling raidstart(), and is
also now the only place that calls raidstart()
- raidstrategy() now just queues requests in buf_queue
and signals rf_RaidIOThread() that work has arrived
Hopefully addresses PR#30233

instead.
Cleanup all uses of rf_ShutdownCreate() to not worry about
it ever failing. Shaves another 600 bytes off of an i386 GENERIC kernel.
|
| 1.31 |
| 02-Jan-2004 |
oster | Fix the "We panic if we can't create a DAG" problem that's existed
~forever. This requires a number of things:
1) If we can't create a DAG, set desc->numStripes to 0 in
rf_SelectAlgorithm. This will ensure that we don't attempt to free
any dagArray[] elements in rf_StateCleanup.
2) Modify rf_State_CreateDAG() to not panic in the event of a DAG
failure. Instead, set the bp->b_flags and bp->b_error, and set things
up to skip to rf_State_Cleanup().
3) Need to mark desc->status as "bad" so that we actually stop looking
for a different DAG. (which we won't find... no matter how many times
we try).
4) rf_State_LastState() will then do the biodone(), and return EIO for
the IO in question.
5) Remove some " || 1 "'s from ProcessNode(). These were for
debugging, and we don't need the failure notices spewing
over and over again as the failing DAGs are processed.
6) Needed to change
if (asmap->numDataFailed + asmap->numParityFailed > 1)
to
if ((asmap->numDataFailed + asmap->numParityFailed > 1) ||
(raidPtr->numFailures > 1)){
in rf_raid5.c so that it doesn't try to return
rf_CreateNonRedundantWriteDAG as the creation function.
7) Note that we can't apply the above change to the RAID 1 code as
with the silly "fake 2-D" RAID 1 sets, it is possible to have 2 failed
components in the RAID 1 set, and that would stop them from working.
(I really don't know why/how those "fake 2-D" RAID 1 sets even work
with all the "single-fault" assumptions present in the rest of the
code.)
8) Needed to protect rf_RAID0DagSelect() in a similar way -- it should
return NULL as the createFunc.
9) No point printing out "Multiple disks failed..." a zillion times.

oster | Nuke a bunch of unused variables:
- node_queue_cond
- quiescent_cond
- eq_cond
- desc->cond
- desc->head

Nuke rf_print_unable_to_init_cond().
Nuke rf_TerminateDiskQueues prototype from rf_diskqueue.h.

| 30-Dec-2003 |
oster | Some days you wonder if some of the function declaration consistency
was just an accident in the first place. Cleanup function decls and
a few comments. [ok.. so I wasn't going to fix this many.. but once
you're on a roll....]
|

oster | Garbage-collect a whole mess of this RF_THREADGROUP_* stuff that isn't
being used. Then, nuke rf_init_managed_threadgroup() and all
descendants and relations.
|
| 1.27 |
| 29-Dec-2003 |
oster | _rf_create_managed_cond() is now left doing nothing. Convert callers.
Mash DO_RAID_COND in rf_driver.c out of existance.
- Nuke (already #if 0'ed) _rf_create_managed_lkmgr_mutex() while we're
busy here.
simplify DO_INIT in rf_engine.c
|
| 1.26 |
| 29-Dec-2003 |
oster | _rf_create_managed_mutex() is doing just a simple:
rf_mutex_init(m)
now. The rest of the fluff is no longer needed.
It also cannot fail, so error checking on rf_create_managed_mutex()
is just wasting space.
Nuke the #define's associated with rf_create_managed_mutex().
Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m).
Remove wasteful "error checking" and simplify all instances where this
is called. (another 0.3K saved in the binary, but the real savings
is in code readability!)

Clean up #includes. Group function prototypes. Fix more 80-column lossage

| 04-Oct-2002 |
oster | Undo the change from 1.16->1.17, and 1.19->1.20. The ltsleep and locking
that was there before before is just fine, and plays nicely with LOCKDEBUG
now that we've added the raidio thread.
|
| 1.23 |
| 04-Oct-2002 |
oster | Tidy up comments and do some 80-column fixing. No functional changes.
|
| 1.22 |
| 04-Oct-2002 |
oster | 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.

oster | branches: 1.5.8;
Disallow interrupting parity re-writes or copybacks by removing PCATCH
from the tsleep()'s (they probably shouldn't have been there in the
first place!). Making parity re-writing and copybacks interruptable
will require re-designing how a few things are done (e.g. how memory
is freed for structures shipped off to routines that run asynchronously
relative to the calling routine). Fix a few other tsleep's while we're at it.
