3441f118d5 Make sure we disk_busy() for every transfer we start. 1996-01-08 21:21:56 +00:00

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.

3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such. 
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

7263209ce6 Make each disk and tape driver define its own read and write functions. 
Deprecate rawread() and rawwrite() completely.  Remove d_strategy from cdevsw to
force the abstraction barrier.

not defined, otherwise use an "not implemented" stub.

8a640328ed clean up several ISA device interfaces: autoconfiguration, header 
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...

3a7bbb1acd lip service to making ISA support machine-independent. This is the first 
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.
