2007-04-28libata: Handle drives that require a spin-up command before first accessMark Lord1-0/+2
(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.

2007-04-28libata: HPA supportAlan Cox1-0/+2
Signed-off-by: Alan Cox <[email protected]> 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 <[email protected]>
2007-04-28libata: add support for READ/WRITE LONGMark Lord1-0/+6
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.

2007-02-15libata: fix drive side 80c cable check, take 3Tejun Heo1-1/+1
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 <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2006-08-10[ATA] Increase lba48 max-sectors from 200 to 256.Jeff Garzik1-0/+2
Also, moved ATA_MAX_SECTORS and ATA_MAX_SECTORS_LBA48 from linux/libata.h to linux/ata.h, now that they truly reflect the standard (well... mostly; note TODO comment). This changes the performance profile (and potential bug profile) for a bunch of drivers, so be wary.

2006-01-06[PATCH] Suspend support for libataJens Axboe1-0/+2
This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.
