* firewire: replace subtraction with bitwise andJarod Wilson2008-01-30
| | | | | | | | | Replace an unnecessary subtraction with a bitwise AND when determining the value of ext_tcode in fw_fill_transaction() to save a cpu cycle or two in a somewhat critical path. Signed-off-by: Jarod Wilson <jwilson@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: fix memory leak of fw_request instancesStefan Richter2007-07-18
| | | | | | | | Found and debugged by Jay Fenlason <fenlason@redhat.com>. The bug was especially noticeable with direct I/O over fw-sbp2. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Kristian Høgsberg <krh@redhat.com>
* firewire: remove bogus check in fw_core_handle_requestStefan Richter2007-07-18
| | | | | | | | | | | This check is bogus: - Maximum asynchronous payload size for S800...S3200 is 4096. - The p->payload_length is totally uninteresting. Only the request->length of the subsequently allocated and initialized struct fw_request is of significance.

* firewire: Switch cdev code over to use register_chrdev and keep a list of ↵Kristian Høgsberg2007-03-09
| | | | | | | | | | devices. The old mechanism kept a struct cdev for each fw device, but fops->release would reference this struct after the device got freed in some cases. 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.

* firewire: consistent usage of node_idStefan Richter2007-03-09
| | | | | | | | | | | | | | 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 Richter2007-03-09
| | | | | | | | | | | | 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>
