      ieee1394: remove superfluous assertions · 00fc3072
      Stefan Richter authored
      hpsb_read, hpsb_write, hpsb_lock are sleeping functions which nobody is
      in danger to use in atomic context.  Besides, in_interrupt does not
      cover all types of atomic context.

      ieee1394: inherit ud vendor_id from node vendor_id · 9c939e4d
      Stefan Richter authored
      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.

      ieee1394: add hpsb_node_read() and hpsb_node_lock() · b33fdd6c
      Stefan Richter authored
      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

      ieee1394: use correct barrier types between accesses of nodeid and generation · 29f8ea8a
      Stefan Richter authored
      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.)

      firesat: copyrights, rename to firedtv, API conversions, fix remote control input · 612262a5
      Stefan Richter authored
      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.

      firedtv: replace tasklet by workqueue job

      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.

      firedtv: nicer registration message and some initialization fixes
          Print the correct name in dvb_register_adapter().
          While we are at it, replace two switch cascades by one for loop, remove
          a superfluous member of struct firesat and of two unused arguments of
          AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init().

      firesat: rename to firedtv
          Suggested by Andreas Monitzer.  Besides DVB-S/-S2 receivers, the driver
          also supports DVB-C and DVB-T receivers, hence the previous project name
          is too narrow now.
          Not yet done:  Rename source directory, files, types, variables...

      firesat: update isochronous interface, add CI support · df4846c3
      Henrik Kurelid authored
      I have finally managed to get the CI support for the card working. The
      implementation is a bare minimum to get encrypted channels to work in
      kaffeine. It works fine with my T/CI card. Now and then I get an AVC
      timeout and have to retune a channel in order to get it to work. Once
      the CAM seemed to hang so I needed to remove and insert it again. I.e.
      there are a number of glitches.
      The latest version contains the following changes:
        - Implemented the new hpsb iso interface so that data can be received
          from the card
        - Reduced some timers for demux setup which caused scanning to timeout
        - Added possibility to unload driver
        - Added support for getting C/N ratio
        - Added two debug parameters to the driver; ca_debug and
        - Added CI support that works for me in kaffeine
        - Started working on CI MMI support. It now supports:
            o Enter menu
            o Receiving MMI objects
        - Added support for 64-bit platforms
        - Corrected DVB-C modulations problems

      This only makes sure that a DVB-S2 device is really recognized as a S2,
      nothing else is added yet. It's using the string containing the model
      that is stored in the configuration ROM, the older version was using
      some hardware revision dependent part of the ROM.

      proc: proc_get_inode should de_put when inode already initialized · cac71121

      de_get is called before every proc_get_inode, but corresponding de_put is
      called only when dropping last reference to an inode. This might cause
      something like
      remove_proc_entry: /proc/stats busy, count=14496
      to be printed to the syslog.
      The fix is to call de_put in case of an already initialized inode in
