bouyer e96144a012 Add a missing ':'. pointed out by Dave Huang. 1999-02-18 14:44:34 +00:00
bouyer a1471db64a move wd.c:print_wderror() to ata.c:ata_perror().
In wdc_probe_caps() add code to guess the ATA revision supported (if
ATA4 if Ultra-DMA, ATA2 if PIO mode > 2). We can't rely on param.atap_ata_major
here, at last one Ultra-DMA drive claims to support only ATA-3.
Use the ATA version in ata_perror(), and to try a flush cache command
in a shutdown hook for IDE drives.

bouyer 1f0d6730cc Switch to single-sector transfert mode only for the last retry, to let
a chance to the underlying driver to downgrade the mode first.

kenh 48f2e0ae6c Add a new flag to wdc_command: ATA_READREG. This will indicate that all
device registers should be read back into the wdc_command structure after
successfull command completion.  Use this this in wdioctl() for
ATAIOCCOMMAND.

kenh 9bc9937238 Add support for the WDCIOCCOMMAND ioctl. This allows the sending of
arbitrary ATA commands from user-space.  Concepts mostly taken from
the implementation of the SCIOCCOMMAND ioctl.

bouyer 1e71e76d6c - clearify the boot messages (features supported vs features used). Thanks to
Havard Eidnes for his complains about this :)
- fix some typo in comments
- hoppefully better detection of drives reporting bogus PIO modes.

bouyer 7bdbb5c993 Donc reset the disk state to 0 in wd.c, set a flag which will cause it
to be reset to 0 at wdcstart(). This fixes a race condition between
normal I/O and wdioclt(). Also use interrupts for wd_get_params in wdopen().

bouyer ff0134b99f Properly separate DEBUF_XFERS and DEBUG_FUNCS: DEBUF_XFERS is for data
transfers (may be called often), where DEBUG_FUNCS is for setup functions
(not used for normal contitions).

mycroft eddaea2d53 In LBA mode, always use the `total capacity' count, rather than calculating
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.

bouyer 68096acabd From Robert V. Baron:
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.

cgd 8540a31ee3 kill a couple of unnecessary #ifs 1998-01-15 01:26:13 +00:00
cgd aaede4d8d8 Various cleanups and bug fixes to the wdc/wd code:
* 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.

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.

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(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.

thorpej 3b4e2a1ac9 In wdattach(), when printing out info about the drive, make the output
look a little more like a SCSI disk's.  This has the pleasant side-effect
of preventing the output from annoyingly extending past 80 columns.

- 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.

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.
