* firewire: fw-sbp2: implement sysfs ieee1394_idStefan Richter2007-05-311-0/+53
| | | | | | | | | The attribute /sys/bus/scsi/devices/*:*:*:*/ieee1394_id, as generated by the old sbp2 driver, is typically used to create persistently named links in /dev/disk/by-id. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>

* firewire: Drop single buffer request support.Kristian Høgsberg2007-05-101-42/+1
| | | | | | | | The SCSI layer only passes sg requests down, so drop the use_sg == 0, request_bufflen != 0 case. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: Allocate scsi_host up front and allocate the sbp2_device as hostdata.Kristian Høgsberg2007-05-101-84/+50
| | | | | | | Avoids an extra allocation and simplifies lifetime rules for the scsi_host. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Provide module aliase for backwards compatibility.Olaf Hering2007-05-101-0/+5
| | | | | | | | | | | | | This patch loads fw-sbp2 if sbp2 is still in the config file. So one can go back and forth between releases without worry about the root filesystem drivers. Signed-off-by: Kristian Hoegsberg <krh@redhat.com> Existing mkinitrd scripts still have to be adapted, unless they grok module aliases. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

| | | | | | | | Signed-off-by: Kristian Høgsberg <krh@redhat.com> (Reverted part which moved it from eh_abort_handler to eh_host_reset_handler) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Only free ORBs that completed the initial transaction.Kristian Høgsberg2007-04-121-1/+4
| | | | | | | | | | | | | In some situations we can receive the ORB status write before we have received the ORB pointer write response. When this happens, we assume that the fw_transaction is finished and free the ORB struct containing the fw_transaction. This fix make the status write logic only accept status writes for ORBs where the initial ORB pointer write transaction finished.

* firewire: Don't time out command orbs, leave that to the scsi stack.Kristian Høgsberg2007-03-091-20/+11
| | | | | | | | | | The mod_timer based timing out of orb was a little to agressive and would time out legit, but long-lived scsi cmds. Besides, the scsi stack keeps track of this already. Since we're only timing out management orbs, go back to wait_for_completion_timeout. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: Complete SCSI commands with DID_BUS_BUSY when a bus reset happens.Kristian Høgsberg2007-03-091-1/+1
| | | | | | | | This lets the SCSI stack retry the command when a SCSI command is interrupted by a FireWire bus reset. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Introduce a retry mechanism for reconnects and logins.Kristian Høgsberg2007-03-091-71/+109
| | | | | | | | Sometimes we reconnect too soon, sometimes too late. Adding a retry mechanism make the reconnect step much more robust. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: fw-sbp2: Do ORB timeout right.Kristian Høgsberg2007-03-091-3/+21
| | | | | | | | | When a management ORB times out, either because the fw_transaction times out or when we don't get the status write, we need to properly cancel the entire operation. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Implement proper transaction cancelation.Kristian Høgsberg2007-03-091-0/+3
| | | | | | | | | | | Drivers such as fw-sbp2 had no way to properly cancel in-progress transactions, which could leave a pending transaction or an unset packet in the low-level queues after kfree'ing the containing structure. fw_cancel_transaction() lets drivers cancel a submitted transaction.

* firewire: fw-sbp2: set command set related device flagsStefan Richter2007-03-091-0/+17
| | | | | | | | | | Copied from sbp2: - enable spin-up by START STOP UNIT for all devices - enable INQUIRY (36) workaround on demand - prefer READ/ WRITE (10) over (6) for all devices - prefer MODE SENSE (10) for MMC devices Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: consistent usage of node_idStefan Richter2007-03-091-4/+4
| | | | | | | | | | | | | | Definitions as per IEEE 1212 and IEEE 1394: Node ID: Concatenation of bus ID and local ID. 16 bits long. Bus ID: Identifies a particular bus within a group of buses interconnected by bus bridges. Local ID: Identifies a particular node on a bus. PHY ID: Local ID of IEEE 1394 nodes. 6 bits long. Never ever use a variable called node_id for anything else than a node ID. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: mark some structs constStefan Richter2007-03-091-1/+1
| | | | | | | | | | | | Instances of struct file_operations and struct fw_card_driver can be qualified as "const". Ditto with struct fw_descriptor.data, struct fw_device_id, and predefined instances of struct fw_address_region, at least in the current implementation. Data qualified as const is placed into the .rodata section which won't be mixed with dirty data. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
