christos 27292adc4c - gcc -Wall fixes 1996-04-29 19:50:47 +00:00
cgd 51e85d07b9 update for addition of a machine-dependent cookie as the first argument
to isa_intr_{,dis}establish().
1996-04-11 22:27:59 +00:00
thorpej de7c200585 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
1996-03-17 00:53:54 +00:00
mycroft 546ad9e88b Add support to the ISA DMA framework for auto-initialize mode.
Add experimental SB16 code, disabled for now.
1996-03-01 04:08:13 +00:00
mycroft 3441f118d5 Make sure we disk_busy() for every transfer we start. 1996-01-08 21:21:56 +00:00
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.

cgd 2c0f263ee7 use wdc_softc in wdccd, rather than wd_softc; from chuck cranor. (pr 828) 1995-02-27 01:08:01 +00:00
cgd 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.

mycroft 9ab5683dc7 Fix problem with reading the disk label if it's not at the beginning of the

mycroft 15d758c39a Remove backward compatibility hacks for config(8), as they are no longer
useful.
1994-03-12 03:45:03 +00:00
mycroft d884f7c425 Update to match config(8). 1994-03-12 03:34:02 +00:00
mycroft 119f3ea688 Various:
Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives
into single-sector mode on the next transfer.  Arrange to wait for an interrupt
after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the
`extra interrupt' messages (except for one immediately after autoconfig on some
machines).  Replace some uses of wdsetctlr() with simply lowering wd->sc_state;
no point in forcing this immediately.  Allow control operations to time out.
Enable the warnings for long busy-wait delays by default.  Some other minor
things not worth mentioning.
1994-03-11 23:29:12 +00:00
mycroft 99dbc0692d Add a heuristic for detecting old config(8)s. This is very temporary. 1994-03-10 22:30:06 +00:00

mycroft 5a17003403 Some changes inspired by Bruce Evans's driver:
Consolidate error reporting in one function.  Actually use the dk_status and
dk_error fields, and pass around only the error bit to avoid lots of unneeded
assignments and tests.  No functional differences.
1994-03-07 05:54:44 +00:00
mycroft 991225bfc8 Remove DKFL_QUIET. 1994-03-07 03:18:35 +00:00

1994-03-04 23:43:14 +00:00

mycroft 220512c2a8 De-ANSIfy. Move the timeout counter into struct disk. Remove unneeded args
to wd[gs]etctlr().  Other minor changes.
1994-03-04 03:43:48 +00:00

cleanup.
