2009-12-29firewire, ieee1394: update Kconfig helpStefan Richter
Update the Kconfig help texts of both stacks to encourage a general move from the older to the newer drivers. However, do not label ieee1394 as "Obsolete" yet, as the newer drivers have not been deployed as default stack in the majority of Linux distributions yet, and those who start doing so now may still want to install the old drivers as fallback for unforeseen issues. Since Linux 2.6.32, FireWire audio devices can be driven by the newer firewire driver stack too, hence remove an outdated comment about audio devices. Also remove comments about library versions since the 2nd generation of libraw1394 and libdc1394 is now in common use; details on library versions can be read at the wiki link from the help texts.

2009-06-21firewire: new stack is no longer experimentalStefan Richter
The new stack is now recommended over the old one if used for industrial video (IIDC/DCAM) or for storage devices (SBP-2) due to better performance, improved compatibility, added features, and security. It should also be functionally on par with and is more secure than the old ieee1394 stack in the use case of consumer video devices. IP-over-1394 support for the new stack is currently emerging, and a backend of the firedtv DVB driver to the new stack should be available soon. The one remaining area where the old stack is still required are audio devices, as the new stack is not yet able to support the FFADO FireWire audio framework.

2009-06-11fs: Remove i_cindex from struct inodeTheodore Ts'o
The only user of the i_cindex element in the inode structure is used is by the firewire drivers. As part of an attempt to slim down the inode structure to save memory --- since a typical Linux system will have hundreds of thousands if not millions of inodes cached, a reduction in the size inode has high leverage. The firewire driver does not need i_cindex in any fast path, so it's simple enough to calculate when it is needed, instead of wasting space in the inode structure.

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

It needs to happen before any firewire driver actually registers itself, and that was previously handled by having the Makefile list the core ieee1394 files before the drivers. But now there are firewire drivers in drivers/media, and the Makefile games aren't enough. So just make ieee1394_init happen earlier in the init sequence, the way all other bus layers already do.

2009-02-24ieee1394: inherit ud vendor_id from node vendor_idStefan Richter
While Module_Vendor_ID in the configuration ROM's root directory is mandatory, there often aren't vendor IDs in unit directories. This affects the new firedtv driver which is meant to be auto-loaded and matched only for vendor-specific devices. We now always copy ne->vendor_id into ud->vendor_id before we scan a unit directory (and fill in a possibly present vendor ID from there). This way, the root directory's vendor ID is used as fallback in the "uevent" environment for modprobe'ing per module alias when a node was plugged in, and in the driver match routine when protocol drivers are bound to unit directories. It will however not be used as sysfs attribute of a unit directory device. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2009-02-24ieee1394: add hpsb_node_read() and hpsb_node_lock()Stefan Richter
These will be used by the firedtv driver. Like hpsb_node_write() they are much better APIs for high-level drivers than hpsb_write() and its siblings --- easier to use correctly and also terser. Unlike hspb_node_write(), the two new functions will only be used by one call site. Hence make them static inline instead of exported symbols.

2009-02-24ieee1394: use correct barrier types between accesses of nodeid and generationStefan Richter
A compiler barrier (explicit on the read side, implicit on the write side) is not quite enough for what has to be accomplished here. Use hardware memory barriers on systems which need them. (Of course a full fix of generation handling would require much more than this. The ieee1394 core's bus generation counter had to be tied to the controller's bus generation counter; cf. Kristian's stack. It's just that I have other current business with the code around these barrier()s, so why not do at least this small fix.) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

input Combination of the following changes: Tue, 26 Aug 2008 00:17:30 +0200 (CEST) firedtv: fix remote control input and update the scancode-to-keycode mapping to a current model. Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter().

This makes sbp2 behave more like firewire-sbp2 which reports 0xff000000 as immediate value if there are no unit directory entries for model_id or firmware_revision. It does not reduce matches with the currently existing quirks table; the only zero entry there is for a device which actually does have a zero model_id. It only changes how model_id and firmware_revision are logged if they are missing. Other functionally unrelated changes: The model_id member of quirks list entries is renamed to model; the value (but not the effect) of SBP2_ROM_VALUE_WILDCARD is changed.

2009-01-24ieee1394: ohci1394: increase AT req. retries, fix ack_busy_X from Panasonic ↵Stefan Richter
camcorders and others Camcorders have a tendency to fail read requests to their config ROM and write request to their FCP command register with ack_busy_X. This has become a problem with newer kernels and especially Panasonic camcorders, causing AV/C in dvgrab and kino to fail. Dvgrab for example frequently logs "send oops"; kino reports loss of AV/C control. I suspect that lower CPU scheduling latencies in newer kernels made this issue more prominent now. According to https://sourceforge.net/tracker/?func=detail&atid=114103&aid=2492640&group_id=14103 this can be fixed by configuring the FireWire controller for more hardware retries for request transmission; these retries are evidently more successful than libavc1394's own retry loop (typically 3 tries on top of hardware retries). Presumably the same issue has been reported at https://bugzilla.redhat.com/show_bug.cgi?id=449252 and https://bugzilla.redhat.com/show_bug.cgi?id=477279 .
