* firewire: Configure channel and speed at context creation time.Kristian Høgsberg2007-03-09
| | | | | | | | We need the channel number as we queue up iso packets for transmission so we can fill out the header correctly. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: Don't touch DMA descriptors after appending.Kristian Høgsberg2007-03-09
| | | | | | | | | When a DMA descriptor is appended to the context we sync it for DMA and the device might potentially read it immediately. So, we can't set the IRQ bits in the descriptor after appending. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Use a buffer fill descriptor for receive when header size is 0.Kristian Høgsberg2007-03-09
| | | | | | | | | When the DMA is setup to not strip any headers, we need to use the buffer fill descriptor instead of the dual buffer, since the dual buffer descriptor must strip a non-zero number of header quadlets.

* firewire: Generalize the iso transmit descriptor buffer logic.Kristian Høgsberg2007-03-09
| | | | | | | | | The descriptor circular buffer logic used for iso transmission is useful for async transmit too, so pull the sharable logic out in a few standalone functions. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* firewire: Split the iso buffer out from fw_iso_context and avoid vmalloc.Kristian Høgsberg2007-03-09
| | | | | | | | | | This patch splits out the iso buffer so we can initialize it at mmap time with the size provided in the mmap call. Furthermore, allocate the backing pages using alloc_page to avoid setting up kernel side virtual memory mappings for the pages.

* firewire: Complete SCSI commands with DID_BUS_BUSY when a bus reset happens.Kristian Høgsberg2007-03-09
| | | | | | | | 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: Schedule topology work before calling driver update functions.Kristian Høgsberg2007-03-09
| | | | | | | | | | | This prevents superfluous bus traffic as fw-sbp2 logs in only to get kicked off the device by another bus reset as the driver core does bus management. Scheduling it this way lets the driver core finish bus management before higher level drivers get the update callback.

* firewire: Introduce a retry mechanism for reconnects and logins.Kristian Høgsberg2007-03-09

* firewire: fw-sbp2: Do ORB timeout right.Kristian Høgsberg2007-03-09
| | | | | | | | | 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 Høgsberg2007-03-09
| | | | | | | | | | | 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: Rework async receive DMA.Kristian Høgsberg2007-03-09
| | | | | | | | | | | | | The old DMA program for receiving async packets stops DMA while processing received packets and only expects one packet per interrupt. Stopping DMA can silently drop packets and we need to handle multiple received packets per interrupt. This new version keeps DMA running at all times and just append new pages as buffers fill up, and supports multiple packets per interrupt.
