53705e35ae Implement the GEOMGETCONF ioctl which returns vital stats for the 
current device in XML in an sbuf.

95c24b31df Make kernel dumps work with GEOM. 
Notice that if the device on which the dump is set is destroyed for
any reason, the dump setting is lost.  This in particular will
happen in the case of spoilage.  For instance if you set dump on
ad0s1b and open ad0 for writing, ad0s* will be spoilt and the dump
setting lost.  See geom(4) for more about spoiling.

1bdb20a68e Implement DIOCGFRONTSTUFF ioctl which reports how many bytes from the start 
of the device magic stuff might occupy.

1265c0ce2b In reverence of the 3rd X11 development rule: 
3.The only thing worse than generalizing from one example
	is generalizing from no examples at all.

Remove the fwcylinders attribute before anybody gets the idea that we
alone have squared the circle.

4c0a424c67 In the absense of any smarter way to do this, cast various printf 
arguments to silence printf format warnings.

b1876192f0 Eliminate some thread pointers which do not make sense anymore. 
Split private parts of geom.h into geom_int.h.  The latter should
never be included in class implemtations.

e805e8f0e8 Cave in to tradition and rename "methods" to "classes". 2002-03-26 21:40:06 +00:00

00dcdc8d67 Add five GEOM oriented ioctls to get basic information about a geom device. 2002-03-19 13:54:15 +00:00

b14d84e24b Change the giant-dropping method a fair bit to keep WITNESS more 
happy.

14e4cefcf8 Hmm, talk about optimizer-fodder. Make the DIOCGDVIRGIN hack work again. 2002-03-16 13:47:57 +00:00

a5b2e75d32 Add a generic and general ioctl pass-through mechanism. 
It should now be posible to issue ioctls to SCSI CD drives.

dd84a43c1d First commit of the GEOM subsystem to make it easier for people to 
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.
