2010-07-27	firewire: nosy: misc cleanups	Stefan Richter	1	-14/+13
	Extend copyright note to 2007, c.f. Kristian's git log. Includes: - replace some <asm/.h> by <linux/.h> - add required indirectly included <linux/spinlock.h> - order alphabetically Coding style related changes: - change to utf8 - normalize whitespace - normalize comment style - remove usages of __FUNCTION__ - remove an unnecessary cast from void * Const and static declarations: - driver_name is not const in pci_driver.name, drop const qualifier - driver_name can be taken from KBUILD_MODNAME - the global variable minors[] can and should be static - constify struct file_operations instance Data types: - Remove unused struct member struct packet.code. struct packet is only used for driver-internal bookkeeping; it does not appear on the wire or in DMA programs or the userspace ABI. Hence the unused member .code can be removed without worries. Preprocessor macros: - unroll a preprocessor macro that containd a return - use list_for_each_entry Printk: - add missing terminating \n in some format strings Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2010-07-27	firewire: new driver: nosy - IEEE 1394 traffic sniffer	Stefan Richter	1	-0/+238
	This adds the traffic sniffer driver for Texas Instruments PCILynx/ PCILynx2 based cards. The use cases for nosy are analysis of nonstandard protocols and as an aid in development of drivers, applications, or firmwares. Author of the driver is Kristian Høgsberg. Known contributers are Jody McIntyre and Jonathan Woithe. Nosy programs PCILynx chips to operate in promiscuous mode, which is a feature that is not found in OHCI-1394 controllers. Hence, only special hardware as mentioned in the Kconfig help text is suitable for nosy. This is only the kernelspace part of nosy. There is a userspace interface to it, called nosy-dump, proposed to be added into the tools/ subdirectory of the kernel sources in a subsequent change. Kernelspace and userspave component of nosy communicate via a 'misc' character device file called /dev/nosy with a simple ioctl() and read() based protocol, as described by nosy-user.h. The files added here are taken from git://anongit.freedesktop.org/~krh/nosy commit ee29be97 (2009-11-10) with the following changes by Stefan Richter: - Kconfig and Makefile hunks are written from scratch. - Commented out version printk in nosy.c. - Included missing <linux/sched.h>, reported by Stephen Rothwell. "git shortlog nosy{-user.h,.c,.h}" from nosy's git repository: Jonathan Woithe (2): Nosy updates for recent kernels Fix uninitialised memory (needed for 2.6.31 kernel) Kristian Høgsberg (5): Pull over nosy from mercurial repo. Use a misc device instead. Add simple AV/C decoder. Don't break down on big payloads. Set parent device for misc device. As a low-level IEEE 1394 driver, its files are placed into drivers/firewire/ although nosy is not part of the firewire driver stack. I am aware of the following literature from Texas Instruments about PCILynx programming: SCPA020A - PCILynx 1394 to PCI Bus Interface TSB12LV21BPGF Functional Specification SLLA023 - Initialization and Asynchronous Programming of the TSB12LV21A 1394 Device Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Kristian Høgsberg <krh@bitplanet.net>
