| * [PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]Tejun Heo2006-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the only per-dev EH action is REVALIDATE. EH used to exploit ehi->dev to do selective revalidation on a ATA bus. However, this is a bit hacky and makes it impossible to request selective revalidation from outside of EH or add another per-dev EH action. This patch adds per-dev EH action mask eh_info->dev_action[] and update EH to use this field for REVALIDATE. Note that per-dev actions can still be specified at port-level and it has the same effect of specifying the action for all devices on the port.

| * | | [PATCH] libata: add host_set->next for legacy two host_sets case, take #3Tejun Heo2006-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a legacy ATA controller, libata registers two separate host sets. There was no connection between the two hosts making it impossible to traverse all ports related to the controller. This patch adds host_set->next which points to the second host_set and makes ata_pci_remove_one() remove all associated host_sets. * On device removal, all ports hanging off the device are properly detached. Prior to this patch, ports on the first host_set weren't detached casuing oops on driver unloading. * On device removal, both host_sets are properly freed This will also be used by new power management code to suspend and resume all ports of a controller. host_set/port representation will be improved to handle legacy controllers better and this host_set linking will go away with it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement SCSI part of hotplug.

| * | | | [PATCH] libata-hp: implement hotplugTejun Heo2006-05-31

To avoid probing broken devices over and over again, disabled devices are not automatically detached. They are detached only if probing is requested for the device or the associated port is offline. Also, to avoid infinite probing loop, Each device is probed only once per EH run. As SATA PHY status is fragile, devices are detached only after it has used up its recovery chances unless explicitly requested by LLDD or user (LLDD may request direct detach if, for example, it supports cold presence detection).

| * | | | [PATCH] libata-hp-prep: add prereset() method and implement ata_std_prereset()Tejun Heo2006-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With hotplug, every reset might be a probing reset and thus something similar to probe_init() is needed. prereset() method is called before a series of resets to a port and is the counterpart of postreset(). prereset() can tell EH to use different type of reset or skip reset by modifying ehc->i.action. This patch also implements ata_std_prereset(). Most controllers should be able to use this function directly or with some wrapping. After hotplug, different controllers need different actions to resume the PHY and detect the newly attached device. Controllers can be categorized as follows. * Controllers which can wait for the first D2H FIS after hotplug. Note that if the waiting is implemented by polling TF status, there needs to be a way to set BSY on PHY status change. It can be implemented by hardware or with the help of the driver. * Controllers which can wait for the first D2H FIS after sending COMRESET. These controllers need to issue COMRESET to wait for the first FIS. Note that the received D2H FIS could be the first D2H FIS after POR (power-on-reset) or D2H FIS in response to the COMRESET. Some controllers use COMRESET as TF status synchronization point and clear TF automatically (sata_sil). * Controllers which cannot wait for the first D2H FIS reliably. Blindly issuing SRST to spinning-up device often results in command issue failure or timeout, causing extended delay. For these controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT (currently 8s) to give newly attached device time to spin up, then issues reset. Note that failing to getting ready in ATA_SPINUP_WAIT is not critical. libata will retry. So, the timeout needs to be long enough to spin up most devices. LLDDs can tell ata_std_prereset() which of above action is needed with ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags. These flags are PHY-specific property and will be moved to ata_link later. While at it, this patch unifies function typedef's such that they all have named arguments.

| * | | | [PATCH] libata-hp-prep: implement sata_phy_debounce()Tejun Heo2006-05-31

Extract PHY waiting code from sata_phy_resume() and extend it to include SStatus debouncing. Note that sata_phy_debounce() is superset of what used to be done inside sata_phy_resume(). Three default debounce timing parameters are defined to be used by hot/boot plug. As resume failure during probing will be properly handled as errors, timeout doesn't have to be long as before. probeinit() uses the same timeout to retain the original behavior.

With hotplug, libata needs to know the attached SCSI device to offline and detach it, but scsi_device_lookup() cannot be used because libata will reuse SCSI ID numbers - dead but not gone devices (due to zombie opens, etc...) interfere with the lookup. dev->sdev doesn't hold reference to the SCSI device.

This patch moves such persistent fields to the top of ata_device and separate them with ATA_DEVICE_CLEAR_OFFSET. Fields above the offset are initialized once during host initializatino while all other fields are cleared before hotplugging. Currently ->ap, devno and part of flags are persistent. Note that flags is partially cleared while holding host_set lock. This is to synchronize with later warm plug implementation which will record hotplug request in dev->flags.
