libata passthru: update cached device paramters

2007-06-10T03:08:12+00:00

INIT_DEV_PARAMS and SET_MULTI_MODE change the device parameters cached by libata. Re-read IDENTIFY DEVICE info and update the cached device paramters when seeing these commands. Signed-off-by: Albert Lee Signed-off-by: Jeff Garzik

libata: Handle drives that require a spin-up command before first access

2007-04-28T18:40:40+00:00

(S)ATA drives can be configured for "power-up in standby", a mode whereby a specific "spin up now!" command is required before the first media access. Currently, a drive with this feature enabled can not be used at all with libata, and once in this mode, the drive becomes a doorstop. The older drivers/ide subsystem at least enumerates the drive, so that it can be woken up after the fact from a userspace HDIO_* command, but not libata. This patch adds support to libata for the "power-up in standby" mode where a "spin up now!" command (SET_FEATURES) is needed. With this, libata will recognize such drives, spin them up, and then re-IDENTIFY them if necessary to get a full/complete set of drive features data. Drives in this state are determined by looking for special values in id[2], as documented in the current ATA specs. Signed-off-by: Mark Lord Signed-off-by: Jeff Garzik

libata: HPA support

2007-04-28T18:16:06+00:00

Signed-off-by: Alan Cox Add support for ignoring the BIOS HPA result (off by default) and setting the disk to the full available size unless already frozen. Tested with various platforms/disks and confirmed to work with the Macintosh (which broke earlier) and ata_piix (breakage due to the LBA48 readback that Tejun fixed). For normal users this brings us, I believe, to feature parity with old IDE (and of course more featured in some areas too). Signed-off-by: Jeff Garzik

libata: add support for READ/WRITE LONG

2007-04-28T18:16:01+00:00

The READ/WRITE LONG commands are theoretically obsolete, but the majority of drives in existance still implement them. The WRITE_LONG and WRITE_LONG_ONCE commands are of particular interest for fault injection testing -- eg. creating "media errors" at specific locations on a disk. The fussy bit is that these commands require a non-standard sector size, usually 520 bytes instead of 512. This patch adds support to libata for READ/WRITE LONG commands issued via SG_IO/ATA_16.

libata: Limit max sector to 128 for TORiSAN DVD drives (take 3)

2007-04-04T06:12:27+00:00

patch 3/4: The TORiSAN drive locks up when max sector == 256. Limit max sector to 128 for the TORiSAN DRD-N216 drives. (http://bugzilla.kernel.org/show_bug.cgi?id=6710) Signed-off-by: Albert Lee Signed-off-by: Jeff Garzik

libata: test major version in ata_id_is_sata()

libata: fix drive side 80c cable check, take 3

2007-02-15T23:04:01+00:00

The 80c wire bit is bit 13, not 14. Bit 14 is always 1 if word93 is implemented. This increases the chance of incorrect wire detection especially because host side cable detection is often unreliable and we sometimes soley depend on drive side cable detection. Fix the test and add word93 validity check. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

libata: straighten out ATA_ID_* constants

2007-02-09T22:39:30+00:00

* Kill _OFS suffixes in ATA_ID_{SERNO|FW_REV|PROD}_OFS for consistency with other ATA_ID_* constants. * Kill ATA_SERNO_LEN * Add and use ATA_ID_SERNO_LEN, ATA_ID_FW_REV_LEN and ATA_ID_PROD_LEN. This change also makes ata_device_blacklisted() use proper length for fwrev. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik
