abs b86f85e1cc wdcwait is called initially without any device on my thinkpad.
This breaks the first WDCDEBUG_PRINT. Handle this case.
1999-02-21 02:07:52 +00:00
hubertf 99626f33a3 Only #define WDCDEBUG if it isn't already defined (e.g. by some options
in the kernel config file).

bouyer 7e5acb7709 Don't print an extra newline if the controller doesn't support 32 bits access.
Pointed out by Dave Huang.

bouyer d683e62685 Be less strict on ATAPI signature, at last one CD puts 0x00 in sc instead
of 0x01.

bouyer 1e0e78854a There's no ATA draft where it is required for the drive to set DRDY | DSC when
the disk is ready to transfer data, and in ATA-5 the DSC has been obsoleted.
So only wait for DRQ to transfer data. This can be made conditional on the
ATA version if it's proven to break with some drives (worked with all the
drives I have access to).
While I'm there correct a few typos.

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 c37bf0ccb4 Keep track of DMA errors, and downgrade the transert mode (UDMA ->DMA,
DMA->PIO) in case of 2 consecutive errors. Don't downgrade if the
PIO/DMA/UDMA modes were forced by a config flag.
1998-12-16 13:02:03 +00:00
bouyer 997074f17c Add a missing 'return' in an error path; noticed by Matthias Drochner. 1998-12-08 13:29:31 +00:00
bouyer 47ab212504 Rename pio_mode, etc ... to PIO_cap, etc ... for consistency with the
ata_drive_datas struct. Suggested by Soren S. Jorvan.

bouyer 71f33dbfa5 UDMA->Ultra-DMA in a printf 1998-12-03 17:30:32 +00:00
bouyer 2b28c858d8 add a udma_mode field to wdc_softc, and use it the same way dma_mode is used
(higthest ultra-dma mode supported). There may be a higther ultra-dma mode
defined ...
1998-12-03 15:38:59 +00:00
bouyer 1d5d5ab40a In struct wdc_xfer, change 'channel' to a pointer to a channel_softc, to avoid
a double-pointer dereference at run-time. Suggested by Matthias Drochner.
1998-12-02 15:53:34 +00:00
bouyer 45675ab14b - change drive_flags from u_int8_t to u_int16_t
- keep the modes supported by the drive in struct ata_drive_datas (will be
  later used for downgrading the DMA/PIO mode on error)
- use config flags to force/disable PIO/DMA/UDMA modes
- For the CMD PCI0643/6 setup DMA mode to DMA Read multiple.
1998-12-02 10:52:24 +00:00
bouyer 5f088e0243 wdcstart(): Re-add support of shared xfer queue across multiple channels
(was lost between 1.44 and 1.45).
1998-11-29 17:34:49 +00:00
kenh 1f676cda09 Implement the AT_READREG flag. This is needed for the CHECK POWER MODE
ATA command (among others).
1998-11-23 23:02:11 +00:00
drochner 3e38051bc5 in wdc_softc: access the per-channel data via a pointer array instead of
an array of fixed-sized channel_softc elements. This way IDE controllers
which more than 1 channel (pciide) can extend the channel data easily
for private needs.
To avoid the double dereference at runtime, change the argument of
wdcstart() to the channel data pointer instead of the array index.

thorpej 4ba3417429 Implement reference counting for ATA adapters. 1998-11-20 01:22:37 +00:00
kenh 396aa17f77 Sigh, my bad. Check for chp->wdc being NULL before trying to deference it.
(I didn't realize the ISA wdc front-end doesn't fill in chp->wdc).
1998-11-19 22:50:21 +00:00
thorpej afc84158d1 Back out revision 1.40. That change couldn't have POSSIBLY worked, since
when wdcprobe() is called, the wdc_softc pointer in the channel_softc
hasn't even been intialized!
1998-11-19 19:52:42 +00:00
kenh 1461c4fb20 __wdccommand_done() needs to call wdcstart(), otherwise you can run
into deadlocks when using wdc_exec_command().
1998-11-19 04:07:54 +00:00
kenh 58932a8415 Quirk out the first test in the beginning of wdcprobe(); the Vaio
CD-ROM drive doesn't like it for some reason.
1998-11-18 19:12:08 +00:00
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.
1998-11-11 19:38:27 +00:00
bouyer 88d1b8138c If WDC_DIAGNOSTIC is defined, check in wdcstart() that we are called at
splbio.
1998-10-21 09:12:46 +00:00
bouyer 794fadcf0a 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().

bouyer 96a0812fd8 Kill an extra printf("\n"). 1998-10-15 11:38:04 +00:00
bouyer e8322de657 Add a new drive flag, DRIVE_MODE, set when the drive properly reported its
PIO/DMA modes. Don't try a SET_FEATURE if it didn't report its mode.

bouyer 7545a59b8c In debug message, always print controller:channel:drive 1998-10-13 15:02:41 +00:00
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).
1998-10-13 09:33:59 +00:00
bouyer da5d0a6f17 pciide.c: don't define WDCDEBUG, so it compiles on alpha. Correct a bogon
in the printing of DMA mode (piix3/4 only)
others: set the debug_mask to 0, so that debug messages are turned off by
default but can be easily turned on.
Reset drive_flags to 0 for unconfigured devices, so that they are ignored
later. For configured devices, reset state to 0 after probe/attach.

thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.

mark 7d6c07a559 Use the data32iot and data32ioh members of the wdc_attachment_data
structure for 32 bit transfers.
Test for 32 bit capability on data transfers currently restricted to 16 bit
only.

kenh 9539399333 Add support for passing device quirks from the attachment routine,
and add support for a NO_EXTRA_RESETS quirk (required by the TEAC
IDE Card/II, which the Vaio uses).

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.

leo fe60e74148 Add hooks to make exclusive hardware locking possible. This is necessary
to make the driver suitable for the atari falcon.

cgd 9264961c87 add a short delay (5ms) after ATAPI software reset is done, suggested by
Soren S. Jorvang <soren@t.dk>.  Apparently some devices Really Want this.

sakamoto a2b24d5571 Change "__BUS_SPACE_NEED_STREAM_METHODS" to "__BUS_SPACE_HAS_STREAM_METHODS". 1998-02-04 14:13:40 +00:00
sakamoto 7052e9949b Change the data access busification functions to
the "stream" busification functions.
In the architecture as the BeBox(CPU is big endian, have ISA bus),
These methods would be used where "raw" data needs to {read,write,set}
unchanged.

Add #ifndef __BUS_SPACE_NEED_STREAM_METHODS (define that on NetBSD/bebox),
if not define __BUS_SPACE_NEED_STREAM_METHODS,
define "stream" busification functions to normal busification functions.

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.
