enami 67e874d814 Allow to detach wdc, atapibus, wd and cd. 1999-09-23 11:04:29 +00:00
enami c08940c49b Fix indentation of close curly brace. 1999-09-22 09:51:03 +00:00
bouyer 7e874499c9 Don't call wddone() from _wdstart(), the ata_wdc system will do it now.
call wd_flushcache() with the proper flags (especially don't set
AT_WAIT | AT_POLL).

bouyer c0da6c9129 Don't use C_NEEDDONE, it's deprecated. 1999-08-09 09:43:11 +00:00
bouyer fae9929734 - Add some debug printf (WDCPROBE) in _wdcreset_wait(), I've needed these
2 times in the past
- Set up timeout per xfer instead of per interrupt. This helps with
  PIO transfer (we would call timeout()/untimout() several times for a
  transfer).
- If we missed an interrupt for a PIO transfer, reset and restart it
  immedialy, don't try to recover and continue. If we missed an interrupt we
  may have lost a read/write cycle on the IDE bus. If this happens 1) we
  corrupt data and 2) we enter an interrupt loop at the end of the xfer, as
  the drive has some more data to read/write, but the host thinks the xfer is
  done.
This last change fix the (or at last some of the) 'lookup after lost interrupt'
some peoples have been experiencing.

bouyer 94d00cdb29 Bump timeout to 10s only for ATAPI devices, 1s is fine for IDE drives once
they are ready.

jonathan 380d12dfbd Complete bugfix in rev 1.3: increase read-parameter-block timeout to 10s
(as used for the hardware for which rev 1.3 was made.)

bouyer b43b844f6f - change the interrupt routines to take a 3rd arguments, set to 1 if we
are called from the interrupt or timeout handler, 0 otherwise.
- use this to know if we can busy-wait for wait_for_unbusy or wait_for_ready
This fixes a bug where CDs withot the DRQ_INTR capability would not busy-wait
for the CMDOUT phase.
While I'm there change 2 delay() to DELAY() for consistency, and
garbage-collect some old code from wdcintr() which has been ifdef'd out
for some time now.
1999-04-01 21:46:28 +00:00
bouyer 1ff88ee466 Avoid busy-waiting when possible if we are not polling (real IRQ or timeout
callback). Shared PCI IRQ should now work (but still untested).

bouyer af9df0ab31 Revert to a 10s timeout, 1s is too low for drives in sleep mode. 1999-03-17 10:13:56 +00:00
bouyer a6365676fa Add a new disk flag: DRIVE_OLD for pre-ATA disks. probe routine will now set
DRIVE_OLD, DRIVE_ATA or DRIVE_ATAPI based on register signatures.
The attach routine will issue a IDENTIFY command for ATA/ATAPI disk,
to detect flase matches by the probe routine.
probe/attach should now be fully compliant with ata-4/ata-5. As a side
effect, ATAPI drives which improperly use ATA register signatures should now
be attached as ATAPI.

bouyer ba74f49e60 Keep track of CRC errors in Ultra-DMA mode. If we noticed a CRC error and we
need to downgrade, downgrade to PIO, as it has been shown if we got CRC errors
in Ultra-DMA mode, we will have silent data corruption in multiword DMA mode
(isn't IDE wonderfull ? :).
Set timeout to 1s for "normal" ata I/O, to minimise the effects of missed
interrupts.

bouyer e96144a012 Add a missing ':'. pointed out by Dave Huang. 1999-02-18 14:44:34 +00:00
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 ce870816e0 Cosmetic changes, from Soren S. Jorvan. 1999-01-29 11:36:20 +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.

augustss 332d7c138f Avoid arithmetic on `void *' since that's not ANSI C. 1999-01-08 18:10:35 +00:00
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 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.

bouyer c10f6edafc AT_ERROR should be different from AT_TIMEOUT. pointed out by Matthias Drochner. 1998-12-04 11:17:54 +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.

tsubai 75ed099b01 struct ataparam has endian dependence, so add big-endian case. 1998-12-01 13:06:37 +00:00
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.
1998-11-23 23:00:26 +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.

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 d74652866f For ATAPI IDENTiFY, poll only for DRQ, some devices don't assert DRDY at this
point.

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 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 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 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).

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
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.
