* libata-sff: make BMDMA optionalTejun Heo2010-05-25
| | | | | | | | | | | | | | | | | | | | | Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA. In Kconfig, drivers are grouped into five groups - non-SFF native, SFF w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic fallback / legacy ones. Kconfig and Makefile are reorganized according to the groups and ordered alphabetically inside each group. ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and functions. This increase the binary size slightly when BMDMA is enabled but on both native-only and PIO-only configurations the size is slightly reduced. Either way, the size difference is insignificant. This change is more meaningful to signify the separation between SFF and BMDMA and as a tool to verify the separation.

* ACPI: do not select ACPI_DOCK from ATA_ACPICarlos R. Mafra2009-12-24
| | | | | | | | | | | | | | | | | | | In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m. However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43 ("dock: make dock driver not a module") removed the possibility of having CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when CONFIG_ATA_ACPI=y. This makes the kernel ~5 Kb smaller for people who don't have a dock by allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y. Signed-off-by: Carlos R.

* | libata/drivers: Add driver for Apple "MacIO" IDE controllerBenjamin Herrenschmidt2009-12-09
|/ | | | | | | | | | | | | | | This is a libata driver for the "macio" IDE controller used on most Apple PowerMac and PowerBooks. It's a libata equivalent of drivers/ide/ppc/pmac.c It supports all the features of its predecessor, including mediabay hotplug and suspend/resume. It should also support module load/unload. The timing calculations have been simplified to use pre-calculated tables compared to drivers/ide/pmac.c and it uses the new mediabay interface provided by a previous patch.

* libata: add command name parsing for error outputRobert Hancock2009-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

When using the POLLING flag there seem to be some interrupts that dosen't get cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts and generates a lot of interrupts due to ripple / noise. What to do?
