2010-07-13firewire: core: fix fw_send_request kerneldoc commentStefan Richter1-11/+5
The present inline documentation of the fw_send_request() in-kernel API refers to userland code that is not applicable to kernel drivers at all. Reported-by: Ben Gamari <bgamari.foss@gmail.com> While we are at fixing the whole documentation of fw_send_request(), also improve the rest of firewire-core's kerneldoc comments: - Add a bit of text concerning fw_run_transaction()'s call parameters. - Append () to function names and tab-align parameter descriptions as suggested by the example in Documentation/kernel-doc-nano-HOWTO.txt. - Remove kerneldoc markers from comments on static functions. - Remove outdated parameter descriptions at build_tree().

2010-07-08firewire: cdev: fix fw_cdev_event_bus_reset.bm_node_idStefan Richter1-0/+1
Fix an obscure ABI feature that is a bit of a hassle to implement. However, somebody put it into the ABI, so let's fill in a sensible value there. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2010-06-19firewire: normalize STATE_CLEAR/SET CSR access interfaceStefan Richter1-3/+2
Push the maintenance of STATE_CLEAR/SET.abdicate down into the card driver. This way, the read/write_csr_reg driver method works uniformly across all CSR offsets. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2010-06-19firewire: replace get_features card driver hookStefan Richter1-2/+1
by feature variables in the fw_card struct. The hook appeared to be an unnecessary abstraction in the card driver interface. Cleaner would be to pass those feature flags as arguments to fw_card_initialize() or fw_card_add(), but the FairnessControl register is in the SCLK domain and may therefore not be accessible while Link Power Status is off, i.e. before the card->driver->enable call from fw_card_add().

2010-06-10firewire: allocate broadcast channel in hardwareClemens Ladisch1-1/+2
On OHCI 1.1 controllers, let the hardware allocate the broadcast channel automatically. This removes a theoretical race condition directly after a bus reset where it could be possible to read the channel allocation register with channel 31 still being unallocated.

2010-06-10firewire: core: add CSR abdicate supportClemens Ladisch1-0/+2
Implement the abdicate bit, which is required for bus manager capable nodes and tested by the Base 1394 Test Suite. Finally, something to do at a command reset! :-) Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2009-10-14firewire: core: optimize Topology Map creationStefan Richter1-7/+10
The Topology Map of the local node was created in CPU byte order, then a temporary big endian copy was created to compute the CRC, and when a read request to the Topology Map arrived it had to be converted to big endian byte order again. We now generate it in big endian byte order in the first place. This also rids us of 1000 bytes stack usage in tasklet context. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2009-06-05firewire: rename source filesStefan Richter1-0/+572
The source files of firewire-core, firewire-ohci, firewire-sbp2, i.e. "drivers/firewire/fw-*.c" are renamed to "drivers/firewire/core-*.c", "drivers/firewire/ohci.c", "drivers/firewire/sbp2.c". The old fw- prefix was redundant to the directory name. The new core- prefix distinguishes the files according to which driver they belong to. This change comes a little late, but still before further firewire drivers are added as anticipated RSN. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
