2001-01-29Fix bug where timeouts triggered too early, caused panic on ATAPI tapes.Niklas Hallqvist
Removed hardcoded WDCDEBUG definitions.

2000-10-29undo this; adds files, unacceptable at this point in releaseTheo de Raadt
2000-10-28Reduce footprint of ATA driver by only having PROBE debug messages compiledConstantine Sapuntzakis
in by default.
2000-07-20Fix to ATA detect. Some devices seem to be comatose after resetConstantine Sapuntzakis
(return 0x00 status persistently). Send them identify to wake them up. Flag value 0x10000 will enable probe messages for a channel/controller. When UKC supports setting flags, this will be useful debugging failing IDE detects without kernel recompiles.
2000-06-30Convert to new timeout API.Artur Grabowski
2000-06-30Convert some parts to new timeouts.Artur Grabowski
2000-04-10Added support for wd detach (merge from NetBSD). Support forConstantine Sapuntzakis
SCSI/ATAPI detach is not here yet. Minor cleanup of wdc. Downgrade to UDMA mode 1 before going further. Want to stay in UDMA modes because they're more error-resilient due to a CRC. Got rid of some of the ridiculous amount of softc sharing going on. Hopefully, this will make the life of whoever goes in and fixes the ref-counting to be correct easier.

1999-11-17New interface to ATA registers that goes through the lower-level deviceConstantine Sapuntzakis
driver (pciide, wdc, etc.) Remove #define WDCDEBUG from top of files More fixes to ATAPISCSI logic: Not all devices transition correctly between phases. Devices are supposed to keep BSY high until they've set the registers to the next sensible state. Some devices drop BSY and leave the registers in an old or nonsense state. Our polling code is extremely sensitive to this (though an early itnerrupt could also observe this). So, if the device is in an unexpected state, the new polling code waits for a while in the hope that it enters a better state. This seems to fix many of the problems reported. Also, there was a horrible bug which would cause sense to fail on a ATAPI command that sent data to the drive
1999-11-05Fix ata_get_params on big endian platforms.Constantine Sapuntzakis
We have diverged from NetBSD in that wdc_exec_xfer no longer automatically swaps.

1999-10-27bugfixes from netbsd ata_wdc.c, ok csapuntz@Chris Cappuccio
from bouyer: - 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.
1999-10-09Fix printout at attach time. Print PIO/DMA mode information after havingConstantine Sapuntzakis
printed line with the name of hard disk.
1999-10-09wdc layer work:Constantine Sapuntzakis
Separate wdc_probe_caps into wdc_probe_caps and wdc_print_caps for more flexibility in printing capability information. Get rid of wdc_final_attach. Include name of device (e.g. cd0), if possible, on errors. atapiscsi layer work: Put a pointer to the SCSI device into ata_drive_datas' drv_softc field Simplify, simplify, simplify. Got rid of a bunch of fields in atapiscsi_softc Delay printing capabilities until we know the real device name (e.g. st0)
1999-09-05Support for ATAPI tapes, works but still has some rough edges. Some style.Niklas Hallqvist
1999-08-15o Correctly set type and typename in driver-generated labelTodd C. Miller
Should really use viscopy() when copying atap_model -> d_packname. When wd's become sd's this will be trivial (viscopy() lives in sd.c)
1999-08-10support DIOCRLDINFOTheo de Raadt
1999-08-05Make IDE compile on alpha again:Niklas Hallqvist
use b* instead of mem* functions, adhere to NISADMA for DMA support.
