* remove ide-scsiFUJITA Tomonori2009-01-023-845/+4
| | | | | | | | | | | | As planed, this removes ide-scsi. The 2.6 kernel supports direct writing to ide CD drives, which eliminates the need for ide-scsi. ide-scsi has been unmaintained and marked as deprecated.

| * [SCSI] fcoe: fix configuration problemsJames Bottomley2008-12-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | fcoe selects libfc and requires SCSI and PCI (the SCSI requirement is implicitly covered by an enclosing if). Fix them both up so they cannot be configured in an invalid state: make LIBFC select SCSI_FC_ATTRS and make FCOE depend on PCI and select LIBFC.

| * [SCSI] cxgb3i: fix select/depend problemJames Bottomley2008-12-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | cxgb3i requires the cxgb3 net driver, so it selects it. However, cxgb3 has dependencies which the select cannot see. Fix this by separating out the cxgb3 dependencies into a separate hidden config option (CONFIG_CHELSIO_T3_DEPENDS) and make both cxgb3 and cxgb3i depend on it.

| | | | | | | | | | | | | | | | | | | | | | | | While doing various error injection testing, such as cable pulls and target moves, some issues were observed in handling these events.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pre-emptively terminate i/o on the rport if dev_loss_tmo has fired.

Also, we do this early enough such that the rport's port_id field is still valid. FCOE libFC code needs this info to find the i/o's to terminate.

The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.

The upper 4 layers are fc_lport, fc_disc, fc_rport and fc_fcp. A LLD that uses libfc could choose to either use libfc's block, or using the transport template defined in libfc.h, override one or more blocks with its own implementation. The EM (Exchange Manager) manages exhcanges/sequences for all commands- ELS, CT and FCP. The framing library frames ELS and CT commands. The fc_lport block manages the library's representation of the host's FC enabled ports. The fc_disc block manages discovery of targets as well as handling changes that occur in the FC fabric (via. RSCN events). The fc_rport block manages the library's representation of other entities in the FC fabric. Currently the library uses this block for targets, its peer when in point-to-point mode and the directory server, but can be extended for other entities if needed. The fc_fcp block interacts with the scsi-ml and handles all I/O.

| * [SCSI] ibmvscsi: Don't fail EH due to insufficient resourcesBrian King2008-12-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ibmvscsi driver currently has a bug in it which can result in it using up all its event structs for commands. If something results in all those commands timing out, we won't have any resources left to send aborts or resets. This results in escalating to a host reset in order to recover, which is a bit heavy handed. This fixes it by reducing can_queue by two in order to have resources to do EH. It also changes the max_requests module parameter so that it is not writable at runtime, since the code really does not handle it changing at runtime.

| * [SCSI] lpfc 8.3.0 : Add active interrupt test for enabling MSI/MSI-X/INTxJames Smart2008-12-294-154/+302
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes scsi_probe_lun() to retry INQUIRY if the device has not actually sent back any INQUIRY data, This enables the Thecus N2050 storage device to work better. The firmware on that device starts up strangely; it sends no data in response to the initial INQUIRY, and it sends the INQUIRY information in response to the followup REQUEST SENSE. But after that it works better, so retrying the INQUIRY is enough to get it going.

| * [SCSI] ibmvfc: Delay NPIV login retry and add retriesBrian King2008-12-292-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Adds a delay prior to retrying a failed NPIV login. This fixes a scenario if the backing fibre channel adapter is getting reset due to an EEH event, NPIV login will fail. Currently, ibmvfc retries three times very quickly, resets the CRQ and tries one more time. If the adapter is getting reset due to EEH, this isn't enough time. This adds a delay prior to retrying a failed NPIV login and also increments the number of retries.
