The driver will add/remove _PRT, so we can eventually remove .bind/.unbind methods. But we found that some of the _ADR-Based devices don't have _PRT, i.e. they are not managed by the new ACPI PCI bridge driver. So that .bind method is not called for some _ADR-Based devices, which leads to a failure. Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver. Extra code path for calling .bind/.unbind when _ADR-Based devices are hot added/removed is also added.

In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer. Note that this involves creating another sas_task bit to indicate whether or not the task has been sent to the LLDD; I could have implemented this by slightly redefining SAS_TASK_STATE_PENDING, but this way seems cleaner.

Wong" Date: Thu, 11 Jan 2007 14:15:20 -0800 Subject: [SCSI] libsas: Delay issuing ABORT TASK TMF until the error handler sas_task_abort() should simply abort the upper-level SCSI command and wait until the error handler to send the actual ABORT TASK command. By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by: Darrick J.

For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense. With this we can mimic the old sense array concept that existed in arch/ppc.

Wong" Date: Fri, 26 Jan 2007 14:08:43 -0800 Subject: [SCSI] libsas: Clean up discovery failure handler code sas_rphy_delete does two things: it removes the sas_rphy from the transport layer and frees the sas_rphy. This can be broken down into two functions, sas_rphy_remove and sas_rphy_free; sas_rphy_remove is of interest to sas_discover_root_expander because it calls functions that require sas_rphy_add as a prerequisite and can fail (namely sas_discover_expander). In that case, sas_discover_root_expander needs to be able to undo the effects of sas_rphy_add yet leave the job of freeing the sas_rphy to the caller of sas_discover_root_expander. This patch also removes some unnecessary code from sas_discover_end_dev to eliminate an unnecessary cycle of sas_notify_lldd_gone/found for SAS devices, thus eliminating a sas_rphy_remove call (and fixing a race condition where a SCSI target scan can come in between the gone and found call). It also moves the sas_rphy_free calls into sas_discover_domain and sas_ex_discover_end_dev to complement the sas_rphy_allocation via sas_get_port_device. This patch does not change the semantics of sas_rphy_delete. Signed-off-by: Darrick J.

Wong" Date: Fri, 26 Jan 2007 14:08:52 -0800 Subject: [SCSI] libsas: Handle SCSI commands that complete with failure codes This patch moves the code that handles SAS failures out of the main EH function and into a separate function. It also detects commands that have no sas_task (i.e. they completed, but with error data) and sends them into scsi_error for processing. This allows us to handle SCSI errors (and enables auto-spinup as a side effect) instead of dropping them on the floor and falling into an infinite loop. It also requires the implementation of a device reset function, which the SAS failure code has been modified to employ for REQ_DEVICE_RESET. Signed-off-by: Darrick J.
