* Introduce a new file, machine/internal_types.h, to hold that specific archespie2002-04-241-2/+2
| | | | | | | | | | | | | type characteristics. internal_types.h will contain only settings invisible from standard C, e.g., in the __* or _[A-Z]* namespace, and be reused by files like limits.h. This allows us to shorten machine/limits.h greatly, as all the common defines are now in sys/limits.h, plus a small stub in internal_types.h. Tested on all arches as far as I know. Approved after discussion with art, millert, deraadt, and others.

* Pool deals fairly well with physical memory shortage, but it doesn't dealart2002-01-231-3/+2
| | | | | | | | | | | | | | | | | | well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
* Enable the RAIDFrame auto-configuration feature.tdeval2001-12-294-112/+449
| | | | | | | | | | | This permits one to setup a kernel able to automatically retrieve, during boot, the raid configuration from disks previously used in a RAIDFrame set. Moreover, one can define a raid set to contain a bootable partition that will be mounted on / before the system has started. A new RAID_AUTOCONFIG kernel option is used, in conjunction with the raid pseudo-device, to activate the feature. ok drahn@, deraadt@

* Fix PR/1489 - apply patch supplied - thanks Michael Joosten <joost@c-lab.de>peter2001-01-021-2/+2
| | | | | | The whole issue of processes and threads need looking at, as NetBSD and OpenBSD do things slightly differently - think extra arg to VOP_XXX calls for one.
* sync RAIDframe with Gre Oster's work for NetBSD.peter2000-08-0834-1049/+3399
| | | | | | | | | | | | | | | | | | | This update incorporates changes since January 2000. RAID1 and RAID5 tested for functionality matching the 2.7 code. A number of bug fixes (including stopping a parity rebuild when unconfiguring) have been included. See Greg's RAIDframe info page: http://www.cs.usask.ca/staff/oster/raid.html The RAID_AUTOCONFIG feature set does *NOT* yet work. These features require more work throughout the boot system and as such are a big task. IMPORTANT: As with anything that is this near live data on your systems, please test carefully with existing configurations before deploying in a live system. Feedback via sendbug or mail direct to peter@wonderland.org is appreciated.
* sync with NetBSDpeter2000-01-1145-1319/+846
| | | | | | | | | | | - removed threadid stuff - removed unused files - general tidyup - you can no longer configure the same unit twice (without de-configuring first of course). Again, this has only been tested locally on IDE disks. Further testing and feedback would be appreciated.

| | | | | | | | | | | | | | | | | | | | | | | | Please note: This update has *only* been tested on i386 with IDE disks. Could someone with a spare box please make sure all is OK with SCSI and maybe other arches ? sparc testing will follow locally. * remove rf_sys.h * many changes to make it more stable * some performance increases * All raid threads now get their own kernel process and the calling raidctl(8) program will show status progress through a meter. * In theory FFS_SOFTUPDATES and RAIDframe will now work together - NOT TESTED YET See http://www.cs.usask.ca/staff/oster/raid.html This updates include Greg's changes to Jan 4th 2000. TODO: * some odd behaviour when running raictl -c on an already config'ed raid set - problem founf, fix being done * progress meter is in raidctl(8) - seperate commit, but could do with sync'ing with OpenBSD ftp version

| | | | | | | | | | * remove init call to rf_ConfigureEtimer() and rf_sys.c in which it is the only function. update conf/files to reflect this. * update sources to make sure _KERNEL is used not KERNEL * change rf_etimer.h to protect macros an include of sys/kernel.h with a check for _KERNEL - let raidctl compile again.
* * rf_reconstruct.c: adopt nilkas' suggestion regard statics andpeter1999-08-038-211/+163
| | | | | | | | | | | | | | | __inline__ - this is a proof of concept and will cover the raidframe source as a whole over coming updates. Update namespace of function to prefix with rf_ - comments again welcome. * overall: rework the macros in rf_etimer.h and the resultant changes to their use to count microseconds and not clock ticks. Restore the code in rf_revent.c to a similar strcuture to before the previous commit, and use the system timers to govern resource usage. Tested with local i386/IDE and the reconstruction of a disk in my array - performance has improved for reconstruction at no noticable CPU cost.

* fix reconstruction performance. the old code used home-grown timerspeter1999-08-021-27/+26
| | | | | | | | | | | | | | | | based upon hardcoded CPU speed values and an assumtion that the number of clock cycles was available. This is/was silly. redone rf_GetNextReconEvent so that is now runs for 1/10th second before sleeping for a short time (1/50th sec). Locally, this is using about 25% of the CPU while rebuilding a disk in a four disk IDE RAID5 array. It was 22% of the way through when I last looked... much much faster. An even better way is sought - suggestions welcome. Lots of code that the old routines relied on canm be harvested later. Patches also being sent to Greg Oster @ NetBSD group.
