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 authored
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. Signed-off-by:

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:

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. Signed-off-by:

This lets the SCSI stack retry the command when a SCSI command is interrupted by a FireWire bus reset. Signed-off-by:
-

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. Signed-off-by:

Sometimes we reconnect too soon, sometimes too late. Adding a retry mechanism make the reconnect step much more robust. Signed-off-by:

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 authored
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. Signed-off-by:

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. Signed-off-by:

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:
