2007-03-09firewire: Generalize the iso transmit descriptor buffer logic.Kristian Høgsberg
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>
2007-03-09firewire: Split the iso buffer out from fw_iso_context and avoid vmalloc.Kristian Høgsberg
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: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Use correct payload pointer when demarshalling incoming requests.Kristian Høgsberg

2007-03-09firewire: Read the *Clear versions of the iso interrupt register.Kristian Høgsberg
The *Clear registers returns the masked value when read which is what we want. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Fix another typo from the bitfield conversion.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Use dma_mapping_error() for checking for DMA mapping errors.Kristian Høgsberg
Pointed out by Pete Zaitcev. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-03-09firewire: Spell out fw as firewire in sysfs.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Complete SCSI commands with DID_BUS_BUSY when a bus reset happens.Kristian Høgsberg
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>
2007-03-09firewire: Schedule topology work before calling driver update functions.Kristian Høgsberg
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: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Introduce a retry mechanism for reconnects and logins.Kristian Høgsberg
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>
2007-03-09firewire: fw-sbp2: Do ORB timeout right.Kristian Høgsberg
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>
2007-03-09firewire: Implement proper transaction cancelation.Kristian Høgsberg
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: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Reduce some redundant register definitions.Kristian Høgsberg
Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-03-09firewire: Rework async receive DMA.Kristian Høgsberg
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: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

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.

2007-03-09firewire: mark some structs constStefan Richter
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>
