/* rf_archs.h -- defines for which architectures you want to
* include is some particular build of raidframe. Unfortunately,
* it's difficult to exclude declustering, P+Q, and distributed
* sparing because the code is intermixed with RAID5 code. This
* should be fixed.
*
* this is really intended only for use in the kernel, where I
* am worried about the size of the object module. At user level and
* in the simulator, I don't really care that much, so all the
* architectures can be compiled together. Note that by itself, turning
* off these defines does not affect the size of the executable; you
* have to edit the makefile for that.
*
* comment out any line below to eliminate that architecture.
* the list below includes all the modules that can be compiled
* out.

* Log: rf_archs.h,v
* Revision 1.32 1996/08/20 23:05:40 jimz

* port simulator to AIX
*
* Revision 1.26 1996/06/17 14:38:33 jimz
* properly #if out RF_DEMO code
* fix bug in MakeConfig that was causing weird behavior
* in configuration routines (config was not zeroed at start)
* clean up genplot handling of stacks
*
* Revision 1.25 1996/06/14 21:24:59 jimz
* turn on RF_CMU_PDL by default
*
* Revision 1.24 1996/06/13 20:41:57 jimz
* add RF_INCLUDE_QUEUE_RANDOM (0)
*
* Revision 1.23 1996/06/11 18:12:36 jimz

* fix some allocation/deallocation and sync bugs
*
* Revision 1.22 1996/06/10 22:24:55 wvcii

* recovery experiments
*
* Revision 1.21 1996/06/05 18:06:02 jimz
* Major code cleanup. The Great Renaming is now done.
* Better modularity. Better typing. Fixed a bunch of
* synchronization bugs. Made a lot of global stuff
* per-desc or per-array. Removed dead code.
*
* Revision 1.20 1996/05/30 11:29:41 jimz
* Numerous bug fixes. Stripe lock release code disagreed with the taking code
* about when stripes should be locked (I made it consistent: no parity, no lock)
* There was a lot of extra serialization of I/Os which I've removed- a lot of
* it was to calculate values for the cache code, which is no longer with us.
* More types, function, macro cleanup. Added code to properly quiesce the array
* on shutdown. Made a lot of stuff array-specific which was (bogusly) general
* before. Fixed memory allocation, freeing bugs.
*
* Revision 1.19 1996/05/27 18:56:37 jimz
* more code cleanup
* better typing
* compiles in all 3 environments
*
* Revision 1.18 1996/05/23 21:46:35 jimz
* checkpoint in code cleanup (release prep)
* lots of types, function names have been fixed
*
* Revision 1.17 1996/05/23 00:33:23 jimz
* code cleanup: move all debug decls to rf_options.c, all extern
* debug decls to rf_options.h, all debug vars preceded by rf_
*
* Revision 1.16 1996/05/18 19:51:34 jimz
* major code cleanup- fix syntax, make some types consistent,
* add prototypes, clean out dead code, et cetera
*
* Revision 1.15 1996/05/15 22:32:59 jimz

* don't INCLUDE_CHAINDECLUSTER in the kernel
* source.
*
