Devices that misreport the validity bit for word 93 look like SATA. If they are on the blacklist then we must not test for SATA but assume 40 wire in the 40 wire case (The TSSCorp reports 80 wire on SATA it seems!)

One or two ancient drives predated the cable spec and didn't sent the valid bits for the field. I had hoped to leave this out of libata as a piece of historical annoyance but a recent CD drive shows the same bug so we have to import support for it. Same concept as Bartlomiej's changes old IDE except that as we have centralised blacklists we can avoid keeping another private table of stuff Signed-off-by: NAlan Cox <alan@redhat.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

A colleague noticed recent versions of Ubuntu no longer detect his 80 GB ST380020ACE drive. This drive is special in that it advertises LBA48 support, but has the lba_capacity_2 field set to zero (cfr. http://lkml.org/lkml/2004/3/30/163). Upon closer look, libata indeed doesn't seem to handle this case yet. Below is an (untested) fix. Signed-off-by: NJeff Garzik <jeff@garzik.org>

Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

Device Initiated Power Management, which is defined in SATA 2.5 can be enabled for disks which support it. This patch enables DIPM when the user sets the link power management policy to "min_power". Additionally, libata drivers can define a function (enable_pm) that will perform hardware specific actions to enable whatever power management policy the user set up for Host Initiated Power management (HIPM). This power management policy will be activated after all disks have been enumerated and intialized. Drivers should also define disable_pm, which will turn off link power management, but not change link power management policy. Documentation/scsi/link_power_management_policy.txt has additional information. Signed-off-by: NKristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

ATA devices in SLEEP mode don't respond to any commands. SRST is necessary to wake it up. Till now, when a command is issued to a device in SLEEP mode, the command times out, which makes EH reset the device and retry the command after that, causing a long delay. This patch makes libata track SLEEP state and issue SRST automatically if a command is about to be issued to a device in SLEEP.

This adds human-readable decoding of the ATA status and error registers (similar to what drivers/ide does) as well as the SATA Serror register to libata error handling output. This prevents the need to pore through standards documents to figure out the meaning of the bits in these registers when looking at error reports. Some bits that drivers/ide decoded are not decoded here, since the bits are either command-dependent or obsolete, and properly parsing them would add too much complexity.

Debugging a report of a problem with an ancient solid state disk showed up some problems in the IORDY handling 1. We check the wrong bit to see if the device has IORDY 2. Even then some ancient creaking piles of crap don't support SETXFER at all. The cases it fixes are obscure and the risk of side effects is slight but possible.

(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.

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).

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.

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.
