| | | | | | | | | | | | This patch removes malloc(), free(), and printf() wrappers from the aic7xxx SCSI driver. I didn't use pr_debug for printf because of some 'clever' uses of printf don't compile with the pr_debug.

* [SCSI] bfa: vport fixesJing Huang2010-07-273-3/+18
| | | | | | | | | | | | | | | | | This patch fixes 3 bugs in vport create/delete. 1) Replace scsi_add_host() with scsi_add_host_with_dma() 2) Fix rmmod hang when there are vports configured. This is due to a race condition between the workqueue destroy in pci remove context and the vport delete works being handled. The fix is to use a counter to track the vport delete work, so that workqueue destroy will not be called until all configured vports are deleted from workqueue. 3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed to be deleted dynamically. However, if someone try to delete it, it leaves the vport is wrong state. The fix is to restore the vport back to original state when the attempt to delete pbc vport delete is failed.

* [SCSI] bfa: fix possible IO double completionJing Huang2010-07-271-0/+34
| | | | | | | | | | | | | | | While processing the ioim in callback functions, the ioim is still in io_q. During this time, if the itnim goes offline, the ioim is requeued from itnim->io_q into itnim->delay_comp_q although the request is already completed. This results in requeing the ioim into the callback queue if the ioim is not freed by the time the ioim is requeued. This results in double completion of the ioim. To fix this, whenever a response is received from firmware for an ioim, deque it from io_q and enque to fcpim->comp_q. This will eliminate any possibility of itnim picking any ioim for which the response is already received.

* [SCSI] bfa: fix link state structureJing Huang2010-07-272-25/+12
| | | | | | | | | | | | | | When the FCoE Linkup event is sent to the host, the link_state (struct bfa_pport_link_s) structure is copied to the RME buf to be sent to the host. But the size of this structure(164 bytes) is larger than the reserved RME buffer size(128 byes). The following changes reduce the size of the structure to be less than RME buffer size(128 bytes): - Remove the trunk and loop info from link_state structure, because both trunk and loop are not supported. - Combine qos_vc_attr and fcf into an union.

| | | | | | | | | | | | | | When a rport goes offline, its speed setting was not reset.

The fix is to reset the speed when processing rport offline transition. In rport attributes, rport's with unknown speed were indicated as TRL enforced. The right thing do to would be to use TRL default speed to determine if TRL is enforced, when TRL is enabled.

| | | | | | | | | | | | | | | | | | fixes surrounding PCIe enhanced error handling: (1) We need to reject all request generated internaly inside the driver as well as request arriving from the scsi mid layer when PCIe EEH is active. The fix is to add a per adapter flag called pci_error_recovery which is checked thru out the driver when request are generated. (2) We don't need to call the pci_driver->remove directly from the PCIe callbacks becuase its already called from the PCIe EEH code. In its place we are shutting down the watchdog timer, and flushing back all pending IO. (3) We need to save and restore the pci state across PCIe EEH handling.
