2000-08-08sync RAIDframe with Gre Oster's work for NetBSD.Peter Galbavy
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.
2000-01-11sync with NetBSDPeter Galbavy
- 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.
2000-01-11remove 'INTEGRATE' macro that did static __inline__ in advance of doingPeter Galbavy
more work on the whole code base
2000-01-11sync with NetBSD - remove an unused prototype.Peter Galbavy
2000-01-08sync with NetBSDPeter Galbavy
- remove unused are from IO_BUF_ERR in rf_driver.c - remove unused define in rf_stripelocks.c
2000-01-07sync with work by Greg Oster on NetBSDPeter Galbavy
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
1999-12-03Init b_dep so that soft updates work.Artur Grabowski

1999-08-04* remove redundant rf_ccmn.hPeter Galbavy
* 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.
1999-08-03* rf_reconstruct.c: adopt nilkas' suggestion regard statics andPeter Galbavy
__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.
1999-08-02revert from using static functions, as per niklas@openbsd.org advice.Peter Galbavy
1999-08-02fix reconstruction performance. the old code used home-grown timersPeter Galbavy
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.
1999-08-02minor style nitPeter Galbavy
1999-08-02* make some function static, copied from rf_netbsdkintf.cPeter Galbavy
* move composition og openmask in raidclose to before where it is tested.
1999-08-02restore the NetBSD specific files to their -current state fromPeter Galbavy
NetBSD. There is no reason to mess with these; they are just being carried around as a reference at the moment.
1999-07-30Update RAIDframe from NetBSD-current as of 1999/07/26.Peter Galbavy
Please note that you *must* follow the upgrade instructions at http://www.cs.usask.ca/staff/oster/clabel_upgrade.html before installing the new raidctl and new kernel using this code.
1999-03-02Remove 3 bad panic cases, which should just report an error upNiklas Hallqvist
to the caller. This fixes some cases of panics due to SCSI errors.
