oster | Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

christos | branches: 1.36.12; 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.
|
1.35 |
| 09-Feb-2019 |
christos | - Change the allocation macros to be more like function calls - Change sizeof(type) -> sizeof(*variable) - Use macros for the long buffer length allocations - Remove "bit polishing" memsets() -- do them only once - Remove unnecessary casts
Thanks to oster@ for finding bugs and testing.

jld | branches: 1.33.4; 1.33.6; 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 | branches: 1.27.8; 1.27.10; Use rf_AllocDAGNode() to get new DAG nodes.
|
1.26 |
| 05-Mar-2004 |
oster | Use RF_INCLUDE_PARITY_DECLUSTERING_DS to #if-out more unneeded bits. (We can't do RF_DISTRIBUTE_SPARE bits without the parity declustering stuff.)
|
1.25 |
| 02-Mar-2004 |
oster | Fix more cases where mutex locks were being held longer than necessary.
[For the record: The mcpair mutex is being used to protect mcpair->flag. mcpair gets allocated before each call to rf_DispatchDAG(), so there is no other process/thread that could be mucking with it. It is only used to detect the completion of a given parity unit, and rf_DispatchDAG() only uses it to setup the callback argument for rf_MCPairWakeupFunc() which will be called when the IO completes. The code after the call to rf_DispatchDAG() sits and waits for a 'wakeup' on mcpair->cond (rf_MCPairWakeupFunc() does that). If mcpair->flag is 0 when rf_DispatchDAG() completes, then rf_MCPairWakeupFunc() hasn't been called yet (the IO hasn't completed). If it is 1, then the IO is already done, and we continue on our merry way without sleeping. Thus, we don't need to hold any lock on mcpair while calling rf_DispatchDAG().]

oster | Use RF_ACC_TRACE to #if out more chunks of code related only to access tracing. (not turned on yet)
|
1.23 |
| 10-Jan-2004 |
oster | iCleanup the RF_CREATE_PARAM3(). Middle two "arguments" were nothing but 0 in all cases.
|
1.22 |
| 31-Dec-2003 |
oster | Fix comments and make function declarations conform. No functional changes.
|
1.21 |
| 31-Dec-2003 |
oster | nuke the 'bp' argument to rf_bxor and friends since it is no longer used. In fact, bp was being set to "NULL" when passed rf_bxor() in rf_parityscan.c:rf_VerifyParityBasic().
|
1.20 |
| 29-Dec-2003 |
oster | - first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

| 29-Dec-2003 |
oster | [Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

oster | Nuke some ancient debugging code.
|
1.16 |
| 23-Sep-2002 |
oster | Clobber basically unused 'pda', and 'unblockNode' and 'wrUnBlock'. Thanks to Simon B.
|
1.15 |
| 21-Sep-2002 |
oster | #if 0 an unused stub. Thanks Krister!
|
1.14 |
| 14-Sep-2002 |
oster | Add two more debugging #defines: RF_DEBUG_RECONBUFFER and RF_DEBUG_VERIFYPARITY. Use them to reduce kernel bloat by a little more.
|
1.13 |
| 13-Jul-2002 |
oster | Most folks won't need the DAG printing and verification routines. Introduce a #define to toggle them on/off. Disable calls to rf_PrintDAGList(). Saves ~6K on GENERIC+DEBUG kernel on i386.

1.12 |
| 13-Nov-2001 |
lukem | branches: 1.12.8; add RCSIDs
|
1.11 |
| 04-Oct-2001 |
oster | Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner.
No functional changes to RAIDframe.

thorpej | branches: 1.10.2; bzero -> memset
|
1.9 |
| 28-May-2000 |
oster | branches: 1.9.4; 1.9.6; Abort any parity re-writes before unconfiguring a RAID set. Partially addresses PR#10182.
|
1.8 |
| 05-Jan-2000 |
oster | branches: 1.8.2; - update RF_CREATE_THREAD to handle a 'process name' argument. - fire up a new thread for parity re-writes, copybacks, and reconstructs. The ioctl's which trigger these actions now return immediately. - add progress accounting for the above actions. - minor rototillage of rf_netbsdkintf.c to deal with all of the above.

1.7 |
| 13-Aug-1999 |
oster | branches: 1.7.2; rf_sys.h does not need to be #included in any of these files, and, actually, is no longer needed at all.
|
1.6 |
| 10-Aug-1999 |
oster | Don't go ape if there is a problem verifying the parity. Note the condition and inform the user (as opposed to panicing the system!).
|
1.5 |
| 10-Aug-1999 |
oster | Trying to rebuild parity on a degraded set is bogus, so don't allow that. Also, check sooner for a RAID 0 set, since rewriting parity makes no sense there either.
|
1.4 |
| 14-Mar-1999 |
oster | branches: 1.4.2; Cleanup rf_RewriteParity() and rf_VerifyParity(). Nuke unused stuff, and make more readable.
|
1.3 |
| 05-Feb-1999 |
oster | Phase 2 of the RAIDframe cleanup. The source is now closer to KNF and is much easier to read. No functionality changes.
|
1.2 |
| 26-Jan-1999 |
oster | RAIDframe cleanup, phase 1. Nuke simulator support, user-land driver, out-dated comments, and other unneeded stuff. This helps prepare for cleaning up the rest of the code, and adding new functionality.
No functional changes to the kernel code in this commit.
|
1.1 |

oster | RAIDframe, version 1.1, from the Parallel Data Laboratory at Carnegie Mellon University. Full RAID implementation, including levels 0, 1, 4, 5, 6, parity logging, and a few other goodies. Ported to NetBSD by Greg Oster.
|
1.4.2.2 |
| 28-Sep-1999 |
cgd | pull up rev 1.6 from trunk (requested by oster): Don't panic the system just because there is a problem verifying the parity.
|
1.4.2.1 |
| 27-Sep-1999 |
cgd | pull up rev 1.5 from trunk (requested by oster): Do not allow rebuilding parity on a degraded RAID set. Also, don't allow parity rewriting on a RAID 0 set, as that makes no sense.
|
1.7.2.1 |
| 20-Nov-2000 |
bouyer | Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
