thorpej 5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

thorpej 862bb3adc1 Pass the correct number of arguments to readdisklabel(). 1995-12-09 07:31:03 +00:00
thorpej 52ec09e420 Use a "match/attach" rather than "init" scheme for probing devices. 
This is a step towards getting the drivers ready for new config.

thorpej 905cb9dda1 Re-arrange things such that we can print out disk geometry regardless of 
COMPAT_NOLABEL.

XXX One day when the world doesn't assume DEV_BSIZE bytes/sector, we'll be
able to actually use the stuff sensed from the drive, rather than a table.
