  • b5e477290   firewire: nosy: misc cleanups ... Browse Code »

    Extend copyright note to 2007, c.f. Kristian's git log.

    Includes:
    - replace some by
    - add required indirectly included
    - 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

  • 286468210   firewire: new driver: nosy - IEEE 1394 traffic sniffer ... Browse Code »

    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 , 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
