libata: Use integer return value for atapi_command_packet_set

2013-04-03T23:33:40Z

The function returns type of ATAPI drives so it should return integer value. The commit 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) since v2.6.39 changed the type of return value from int to bool, the change would cause all of the ATAPI class drives to be treated as TYPE_TAPE and the max_sectors of the drives to be set to 65535 because of the commit f8d8e5799b7(libata: increase 128 KB / cmd limit for ATAPI tape drives), for the function would return true for all ATAPI class drives and the TYPE_TAPE is defined as 0x01.

[libata] replace sata_settings with devslp_timing

2013-01-14T18:29:15Z

NCQ capability was used to check availability of SATA Settings page from Identify Device Data Log, which contains DevSlp timing variables. It does not work on some HDDs and leads to error messages. IDENTIFY word 78 bit 5(Hardware Feature Control) can't work either because it is only the sufficient condition of Identify Device data log, not the necessary condition. This patch replaced ata_device->sata_settings with ->devslp_timing to only save DevSlp timing variables(8 bytes), instead of the whole SATA Settings page(512 bytes).

ahci: implement aggressive SATA device sleep support

2012-09-13T05:08:53Z

Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal. This feature enables an HBA and SATA storage device to enter the DevSleep interface state, enabling lower power SATA-based systems. Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as soon as there are no commands outstanding to the device and the port specific Device Sleep idle timer has expired. This enables autonomous entry into the DevSleep interface state without waiting for software in power sensitive systems. This patch enables Aggressive Device Sleep only if both host controller and device support it. Tested on AMD reference board together with Device Sleep supported device sample.

libata: Use 'bool' return value for ata_id_XXX

Most ata_id_XXX inlines are simple tests, so we should set the return value to 'bool' here. Signed-off-by: Hannes Reinecke Signed-off-by: Jeff Garzik

[libata] support for > 512 byte sectors (e.g. 4K Native)

2010-10-22T00:21:03Z

This change enables my x86 machine to recognize and talk to a "Native 4K" SATA device. When I started working on this, I didn't know Matthew Wilcox had posted a similar patch 2 years ago: http://git.kernel.org/?p=linux/kernel/git/willy/ata.git;a=shortlog;h=refs/heads/ata-large-sectors Gwendal Grignou pointed me at the the above code and small portions of this patch include Matthew's work. That's why Mathew is first on the "Signed-off-by:". I've NOT included his use of a bitmap to determine 512 vs Native for ATA command block size - just used a simple table. And bugs are almost certainly mine. Lastly, the patch has been tested with a native 4K 'Engineering Sample' drive provided by Hitachi GST.

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

2010-04-08T16:53:57Z

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. Signed-off-by: Mark Lord Signed-off-by: Jeff Garzik
