| * [PATCH] fix compile regression for a few scsi driversChristoph Hellwig2006-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes three drivers to compile again after my patch that removes the data_cmnd member from struct scsi_cmnd. The fas216 change is trivial, it should have been using ->cmnd all the time. NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing something odd, it should only have looked at ->cmnd before not the saved copy that is kept for the error handlers sake. Note that it really should deal with the sync setting themselves but use the generic domain validation code that get this right - but that's for later let's push this simple compile fix for now. And sorry for the late fix for this, I have been busy with OLS and associated activities last week. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently the D700 has had an argument ordering issue for quite a while which can cause it to get the wrong scsi_id (I just got an unbootable voyager system because of this).

| | * [SCSI] hide EH backup data outside the scsi_cmndChristoph Hellwig2006-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently struct scsi_cmnd has various fields that are used to backup original data after the corresponding fields have been overridden for EH commands. This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size. This patch moves them onstack in scsi_send_eh_cmnd to fix those two issues aswell as allowing future EH fixes like moving the EH command submissions to use SG lists like everything else.

| | * [SCSI] scsi_transport_sas: add unindexed portsJames Bottomley2006-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SAS HBAs don't want to go to the trouble of tracking port numbers, so they'd simply like to say "add this port and give it a number". This is especially beneficial from the hotplug point of view, since tracking ports and the available number space can be a real pain. The current implementation uses an incrementing number per expander to add the port on. However, since there can never be more ports than there are phys, a later implementation will try to be more intelligent about this. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and EHI flag handling. * There are two types of EHI flags - one which expires on successful EH and the other which expires on a successful reset. Make this distinction clear. * Unlike other EH actions, reset actions are represented by two EH action masks and a EHI modifier. Implement correct about_to_do/done semantics for resets. That is, prior to reset, related EH info is sucked in from ehi and cleared, and after reset is complete, related EH info in ehc is cleared. These changes improve consistency and remove unnecessary EH actions caused by stale EH action masks and EHI flags.

Fix it. * Link resuming resets shouldn't be skipped. Don't skip recovery on EHI_RESUME_LINK. This doesn't matter for host ports as EHI_RESUME always coincides with EHI_HOTPLUGGED which makes attached disabled devices vacant. However, PMP reset causes non-hotplug link-resuming resets which shouldn't be skipped. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

This broke action mask clearing on SENSE_VALID case causing revalidation and EH complete message on successful ATAPI CC. This patch removes two local variables - action and failed_dev - which cache ehc->i.action and ehc->i.dev respectively, and make the function directly modify ehc->i.* fields to remove aliasing issues.

In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports. Signed-off-by: Jeff Garzik <jeff@garzik.org>
