ahci: do not fail softreset if PHY reports no device

2006-10-13T18:50:11+00:00

All softreset methods are responsible for detecting device presence
and succeed softreset in such cases.  AHCI didn't use to check for
device presence before proceeding with softreset and this caused
unnecessary reset retrials during probing.  This patch adds presence
detection to AHCI softreset.

[PATCH] sata_mv: grab host lock inside eng_timeout

2006-06-12T03:03:18+00:00

Bug fix:  mv_eng_timeout() calls mv_err_intr() without first grabbing the host lock,
which can lead to all sorts of interesting scenarios.

This whole error-handling portion of sata_mv is nasty (and will get fixed for
the new EH stuff), but for now this patch will help keep it on life-support.

[SCSI] scsi_lib.c: properly count the number of pages in scsi_req_map_sg()

2006-06-01T14:16:55+00:00

The calculation of nr_pages in scsi_req_map_sg() doesn't account for
the fact that the first page could have an offset that pushes the end
of the buffer onto a new page.

[PATCH] the latest consensus libata resume fix

2006-05-28T20:32:08+00:00

Okay, just to sum things up.

This forces libata to wait for up to 2 seconds for BUSY|DRQ to clear
on resume before continuing.

[jgarzik adds...]  During testing we never saw DRQ asserted, but
nonetheless (a) this works and (b) testing for DRQ won't hurt.

[SCSI] scsi_transport_sas: make write attrs writeable

2006-05-20T14:02:28+00:00

A couple write attributes in sas transport layer have a small
bug that prevents them from being written to.  Those
attributes are the link_reset and write_reset.  This is due
the store field being set to NULL.
