as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
the capacity based on the c/h/s numbers. In fact, don't use the c/h/s
numbers for much of anything.
For ATA-4 drives or later, always use LBA mode, since it's now required.
Collectively, this allows >8GB disks (like the 12GB Bigfoot) to work.
Compute the disk block addr at command queing time rather than exec time.
This fix a bug which could lead to data corruption on disk: when a command
was reexecuted after an error condition (from wdcunwedge), the partition
offset was re-added to the block addr, leading to a transfert at the wrong
disk block.
This should fix the problem reported by some laptop's users, where the
first disk read after a suspend/resume returned garbage.
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
even if there are no drives attached, and so that it works
properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
completely true, but mostly so; they at least work on arm32 and
i386).
* Various other minor fixups and cleanups, some of which were pointed
out by Kazuki Sakamoto.
now lives in dev/ic, wd now lives in dev/ata. there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.
pseudo-device rnd # /dev/random and in-kernel generator

o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
be probed several times. This fixes the "ATAPI CD probed as wd drive" problem.
Thanks to Geoff Wing <mason@primenet.com.au> for testing this on his hardware.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
- 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.
- 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.
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.
* Add a dkdevice; move sc_*openpart, sc_label, and sc_cpulabel into it.
* Turn sc_wlabel into a flag, and don't set it automatically in DIOCWLABEL.
* If there is no label, disallow all I/O except to the raw partition.
* Don't allow I/O to `unused' partitions.
* Beginnings of support for block sizes other than 512 bytes.
Other minor changes.
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.
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.
rahter than unit numbers where appropriate. Fix conflict if two drives have
I/O pending at the same time. Add some more sanity checks. Some other minor
cleanup.
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.
additionally fixes some of the (newer ending) while loops
(that made it work with two IDE disks !)
1. controller reset code moved into one function, called from more places now.
2. more places now do timeouts. TIPCAT code turned on.
3. blew away the unused WDOPENLOCK test code.
4. delay is now done using WDCNDELAY repetitions of DELAY(25). Up to 2.5 second
pause accepted from controller (some controllers have some commands that are
actually this slow)
5. some of the old timeout code was really whacked.
WD1007-derived controllers. In this example, wdc0 is a WD1007-clone,
and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI
and IDE controllers.

devices hanging off controllers, any kind of controller.
A device on isa0 is called at probe(self), then attach(self)
A controller on isa0 is called at probe(self), then all it's children with
defined unit numbers are initialized by calling attach(subdev); next all
subdevices with unit ? are initialized by calling attach(sundev).
Almost all device entry points is now like the vax/sun model (intr being
the weird one)
controllers. New behaviour is that if the standard method fails, try
to recalibrate the drive. Success means the drive exists. patch by

artifacts)
