libata: Fix accesses at LBA28 boundary (old bug, but nasty) (v2)

2010-05-12T21:57:10Z

commit 45c4d015a92f72ec47acd0c7557abdc0c8a6499d upstream. Most drives from Seagate, Hitachi, and possibly other brands, do not allow LBA28 access to sector number 0x0fffffff (2^28 - 1). So instead use LBA48 for such accesses. This bug could bite a lot of systems, especially when the user has taken care to align partitions to 4KB boundaries. On misaligned systems, it is less likely to be encountered, since a 4KB read would end at 0x10000000 rather than at 0x0fffffff.

libata: implement more acpi filtering options

2009-10-06T04:26:26Z

Currently libata-acpi can only filter DIPM among SATA feature enables via _GTF. This patch adds the capability to filter out FPDMA non-zero offset, in-order guarantee and auto-activation. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

libata: cosmetic updates

2009-10-06T04:25:03Z

We're about to add more SATA_* and ATA_ACPI_FILTER_* constants. Reformat them in preparation. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

libata: add command name parsing for error output

2009-09-01T23:47:20Z

This patch improve libata's output for error/notification messages to allow easier comprehension and debugging: When ATAPI commands issued through the SCSI layer fail, use SCSI functions to print the CDB in human-readable form instead of just dumping out the CDB in hex. Print out the name of the failed command (as defined by the ATA specification) in error handling output along with the raw register contents. When reporting status of ACPI taskfile commands executed on resume, also output the names of the commands being executed (or not) in readable form. Since the extra data for printing command names increases kernel size slightly, a config option has been added to allow disabling command name output (as well as some of the error register parsing) for those highly sensitive to kernel text size.

[libata] add DMA setup FIS auto-activate feature

2009-09-01T23:47:19Z

Hopefully results in fewer on-the-wire FIS's and no breakage. We'll see! Signed-off-by: Shaohua Li Signed-off-by: Jeff Garzik

ata: add ata_id_pio_need_iordy() helper (v2)

2009-06-15T16:52:52Z

v2: Minor fixes per Sergei's review. Cc: Sergei Shtylyov Cc: Jeff Garzik Signed-off-by: Bartlomiej Zolnierkiewicz

libata: Media rotation rate and form factor heuristics

2009-05-15T18:14:56Z

This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever. With no complaints so far. Signed-off-by: Martin K. Petersen Signed-off-by: Jeff Garzik
