* [PATCH] libata: reimplement per-dev PMTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] libata: implement PM EH actionsTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] libata: implement ATA_EHI_NO_AUTOPSY and QUIETTejun Heo2006-07-05
| | | | | | | | | | 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.

* [PATCH] libata: clean up debounce parameters and improve parameter selectionTejun Heo2006-07-05
| | | | | | | | | | | | | | 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.

* [PATCH] libata: implement ATA_EHI_RESUME_LINKTejun Heo2006-07-05
| | | | | | | | | | | | | 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>
* [PATCH] libata: replace ap_lock w/ ap->lock in ata_scsi_error()Tejun Heo2006-07-05
| | | | | | | | | | | | | | | 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>
* [PATCH] libata: fix ehc->i.action setting in ata_eh_autopsy()Tejun Heo2006-07-05
| | | | | | | | | | ata_eh_autopsy() used to directly assign determined action mask to ehc->i.action thus overriding actions set by some of nested analyze functions.

| | | | | | | | | | ap->flags is way too clamped. Separate out core dynamic flags to ap->pflags. ATA_FLAG_DISABLED is a dynamic flag but left alone as it's referenced by a lot of LLDs and it's gonna be removed once all LLDs are converted to new EH.

This addresses the Samsung P30 issue, where the INIT method would return no object, but the implicit return in the AML interpreter would confuse the driver. It also accounts for a newer batch of Asus models whose INIT returns ACPI_TYPE_BUFFER instead of STRING. The handling is now much leaner, if we get a buffer or a string, we check against known values, in every other case we use a different path (currently DSDT signatures). The bulk of this patch is separating the string matching from asus_hotk_get_info() into a separate function. This patch properly fixes http://bugme.osdl.org/show_bug.cgi?id=5067 and http://bugme.osdl.org/show_bug.cgi?id=5092 and makes the driver fully functional again with acpi=strict on all machines.
