sata_mv: correct S/G table limits

2007-10-09T19:38:26+00:00

The recent mv_fill_sg() rewrite, to fix a data corruption problem
related to IOMMU virtual merging, forgot to account for the
potentially-increased size of the scatter/gather table after its run.

Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff
to more closely match the needs of mv_fill_sg().

libata: fix for sata_mv >64KB DMA segments

2007-10-03T18:41:20+00:00

Fix bug in sata_mv for cases where the IOMMU layer has merged SG entries
to larger than 64KB. They need to be split up before being sent to
the driver.

Just for simplicity's sake, split up at 64K boundary instead of 64K size,
since that's what the common code does anyway.

ata_piix: add another TECRA M3 entry to broken suspend list

2007-10-02T14:54:02+00:00

proper vendor and product name entry.  Add the entry to the broken
suspend list.

Angus Turnbull reported and provided initial patch.

pata_sis: add missing UDMA5 timing value in sis_66_set_dmamode()

2007-09-26T01:30:56+00:00

sis_66_set_dmamode() also handles early UDMA100 (SIS630 ET) but is
missing udma timing value for UDMA100.  According to sis5513, this
should be 0x8000.  This caused UDMA100 device to fail on pata_sis till
it downgrades to UDMA66 while it works fine on sis5513 at UDMA100.

sata_sil24: fix IRQ clearing race when PCIX_IRQ_WOC is used

2007-09-26T01:30:56+00:00

When PCIX_IRQ_WOC is used, sil24 has an inherent race condition
between clearing IRQ pending and reading IRQ status.  If IRQ pending
is cleared after reading IRQ status, there's possibility of lost IRQ.
If IRQ pending is cleared before reading IRQ status, spurious IRQs
will occur.

sata_sil24 till now cleared IRQ pending after reading IRQ status thus
losing IRQs on machines where PCIX_IRQ_WOC was used.  Reverse the
order and ignore spurious IRQs if PCIX_IRQ_WOC.
