pata_netcell: LBA48 force identify bits correct

2009-06-02T16:49:46+00:00

This matches Bartlomiej's patch for ide_pci_generic:
c339dfdd65b52bfd947ab29d1210314a2f6d622d

In the libata case netcell has its own mini driver. I suspect this fix is
actually only needed for some firmware revs but it does no harm either way.

libata: Media rotation rate and form factor heuristics

2009-05-15T18:14:56+00:00

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.

libata: Report disk alignment and physical block size

2009-05-15T18:14:22+00:00

For disks with 4KB sectors, report the correct block size and alignment
when filling out the READ CAPACITY(16) response.

This patch is based upon code from Matthew Wilcox' 4KB ATA tree.  I
fixed the bug I reported a while back caused by ATA and SCSI using
different approaches to describing the alignment.

sata_fsl: Fix the command description of FSL SATA controller

2009-05-15T18:14:08+00:00

The bit 11 of command description is reserved bit in Freescale
SATA controller and needs to be set to '1'.  This is needed to
make sure the last write from the controller to the buffer
descriptor is seen before an interrupt is raised.

sata_fsl: Fix compile warnings

2009-05-15T18:14:01+00:00

We we build with dma_addr_t as a 64-bit quantity we get:

drivers/ata/sata_fsl.c: In function 'sata_fsl_fill_sg':
drivers/ata/sata_fsl.c:340: warning: format '%x' expects type 'unsigned int', but argument 4 has type 'dma_addr_t'

[libata] sata_sx4: fixup interrupt handling

2009-05-15T18:08:10+00:00

Issuing ATA_CMD_SET_FEATURES (0xef) times out because
pdc20621_interrupt ignores command completion since
ATA_TFLAG_POLLING flag is set.

This has already been fixed for sata_promise:

ata_piix: ICH7 does not support correct MWDMA timings

2009-05-11T18:31:34+00:00

See Errata documentation. The recommended workaround is to use PIO4 instead
which will we automatically do by flagging this mode not available.
