2006-07-09[SCSI] hide EH backup data outside the scsi_cmndChristoph Hellwig7-224/+108
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.

2006-07-09[SCSI] scsi_transport_sas: add unindexed portsJames Bottomley1-1/+35
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>

2006-07-05[PATCH] libata: reimplement controller-wide PMTejun Heo2-7/+286
Reimplement controller-wide PM. ata_host_set_suspend/resume() are defined to suspend and resume a host_set. While suspended, EHs for all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and frozen. Because SCSI device hotplug is done asynchronously against the rest of libata EH and the same mutex is used when adding new device, suspend cannot wait for hotplug to complete. So, if SCSI device hotplug is in progress, suspend fails with -EBUSY. In most cases, host_set resume is followed by device resume. As each resume operation requires a reset, a single host_set-wide resume operation may result in multiple resets. To avoid this, resume waits upto 1 second giving PM to request resume for devices.

2006-07-05[PATCH] libata: reimplement per-dev PMTejun Heo2-90/+115
Reimplement per-dev PM. The original implementation directly put the device into suspended mode and didn't synchronize w/ EH operations including hotplug. This patch reimplements ata_scsi_device_suspend() and ata_scsi_device_resume() such that they request EH to perform the respective operations. Both functions synchronize with hotplug such that it doesn't operate on detached devices. Suspend waits for completion but resume just issues request and returns. This allows parallel wake up of devices and thus speeds up system resume. Due to sdev detach synchronization, it's not feasible to separate out EH requesting from sdev handling; thus, ata_device_suspend/resume() are removed and everything is implemented in the respective libata-scsi functions.

2006-07-05[PATCH] libata: implement PM EH actionsTejun Heo2-3/+187
Implement two PM per-dev EH actions - ATA_EH_SUSPEND and ATA_EH_RESUME. Each action puts the target device into suspended mode and resumes from it respectively. Once a device is put to suspended mode, no EH operations other than RESUME is allowed on the device. The device will stay suspended till it gets resumed and thus reset and revalidated. To implement this, a new device state helper - ata_dev_ready() - is implemented and used in EH action implementations to make them operate only on attached & running devices. If all possible devices on a port are suspended, reset is skipped too. This prevents spurious events including hotplug events from disrupting suspended devices.

2006-07-05[PATCH] libata: implement ATA_EHI_NO_AUTOPSY and QUIETTejun Heo2-16/+21
Implement ATA_EHI_NO_AUTOPSY and QUIET. These used to be implied by ATA_PFLAG_LOADING, but new power management and PMP support need to use these separately. e.g. Suspend/resume operations shouldn't print full EH messages and resume shouldn't be recorded as an error.

2006-07-05[PATCH] libata: clean up debounce parameters and improve parameter selectionTejun Heo2-15/+12
The names of predefined debounce timing parameters didn't exactly match their usages. Rename to more generic names and implement param selection helper sata_ehc_deb_timing() which uses EHI_HOTPLUGGED to select params. Combined with the previous EHI_RESUME_LINK differentiation, this makes parameter selection accurate. e.g. user scan resumes link but normal deb param is used instead of hotplug param.

2006-07-05[PATCH] libata: implement ATA_EHI_RESUME_LINKTejun Heo2-7/+9
Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However, hotplug isn't the only event which requires link resume and separating this out allows other places to request link resume. This differentiation also allows better debounce timing selection. This patch converts user scan to use ATA_EHI_RESUME_LINK. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-07-05[PATCH] libata: replace ap_lock w/ ap->lock in ata_scsi_error()Tejun Heo1-12/+11
ap_lock was used because &ap->host_set->lock was too long and used a lot. Now that &ap->host_set->lock is replaced with ap->lock, there's no reason to keep ap_lock. [ed. note: that's not entirely true. ap_lock is a local variable, caching the results of a de-ref. In theory, if the compiler is smart enough, this patch is cosmetic. However, since this is not a fast path (it is the error path), this patch is nonetheless acceptable, even though it _may_ introduce a performance regression.] Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
