oster ee19b085aa - 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.

oster 10f077a0fb [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 540f566858 rf_SelectMirrorDiskPartition() is only needed in a few cases. #if it
out in the rest.  Thanks to Krister!

oster d5e793770c Remove unneeded variables and lame assignments. Thanks Simon B.! 2002-09-23 02:49:14 +00:00
oster cbf5be6ee1 rf_MakePropListEntry isn't used anywhere, so nuke it. Thanks Krister! 2002-09-21 00:56:57 +00:00
oster 8a7eefa217 Another couple of functions that arn't used unless one is debugging RAIDframe. 2002-09-19 23:29:03 +00:00
oster a2b9142871 Everyone and their dog was using RF_ERRORMSG3 to print out the same
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space.  Also improves readability of code.

oster fcc4232f71 Nuke stuff dealing with the experimental memChunk code. It's unused, and
currently only contributing to bloat.

oster bc8ead0c0a 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.

oster 28ce42a2bb Minor cleanup. 2002-07-13 19:59:26 +00:00
oster 33643c74c5 rf_compute_workload_shift() is only used by the CHAINDECLUSTER stuff,
so only include it if needed.

oster 765e00d3de 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.

oster a0d72cb555 Trust only the data disk if the mirror is not known to be up-to-date.
(this should have been committed with a previous fix for the same
problem in another function in this file :( )

oster 3949e74f78 If we have a choice: do not trust the parity disk for read
balancing in a RAID 1 set if we know that the parity might not
be up-to-date.  Thanks to Thor for bringing this to my attention.

oster db2eaf18cf rf_sys.h does not need to be #included in any of these files, and, actually,
is no longer needed at all.

oster 0014588545 Phase 2 of the RAIDframe cleanup. The source is now closer to KNF
and is much easier to read.  No functionality changes.

oster 1eecf8e491 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.

oster 38a3987b69 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.
