      [media] rc-core: add separate defines for protocol bitmaps and numbers · c003ab1b
      David Härdeman 提交于
      The RC_TYPE_* defines are currently used both where a single protocol is
      expected and where a bitmap of protocols is expected.
      
      Functions like rc_keydown() and functions which add/remove entries to the
      keytable want a single protocol. Future userspace APIs would also
      benefit from numeric protocols (rather than bitmap ones). Keytables are
      smaller if they can use a small(ish) integer rather than a bitmap.
      
      Other functions or struct members (e.g. allowed_protos,
      enabled_protocols, etc) accept multiple protocols and need a bitmap.
      
      Using different types reduces the risk of programmer error. Using a
      protocol enum whereever possible also makes for a more future-proof
      user-space API as we don't need to worry about a sufficient number of
      bits being available (e.g. in structs used for ioctl() calls).
      
      The use of both a number and a corresponding bit is dalso one in e.g.
      the input subsystem as well (see all the references to set/clear bit when
      changing keytables for example).
      
      This patch separate the different usages in preparation for
      upcoming patches.
      
      Where a single protocol is expected, enum rc_type is used; where one or more
      protocol(s) are expected, something like u64 is used.
      
      The patch has been rewritten so that the format of the sysfs "protocols"
      file is no longer altered (at the loss of some detail). The file itself
      should probably be deprecated in the future though.

      [media] IR: extend ir_raw_event and do refactoring · 4651918a
      Maxim Levitsky 提交于
      Add new event types for timeout & carrier report
      Move timeout handling from ir_raw_event_store_with_filter to
      ir-lirc-codec, where it is really needed.
      Now lirc bridge ensures proper gap handling.
      Extend lirc bridge for carrier & timeout reports
      
      Note: all new ir_raw_event variables now should be initialized
      like that: DEFINE_IR_RAW_EVENT(ev);
      
      To clean an existing event, use init_ir_raw_event(&ev);

      V4L/DVB: IR/streamzap: functional in-kernel decoding · 7a569f52
      Jarod Wilson 提交于
      This patch makes in-kernel decoding with the stock Streamzap PC Remote
      work out of the box. There are quite a few things going on in this
      patch, all related to getting this working:
      
      1) I had to enable reporting of a long space at the end of each signal,
         or I had weird buffering and keybounce issues.
      
      2) The keymap has been reworked slightly to match actual decoded values,
         the first edition was missing the pre-data bits present in the lirc
         config file for this remote.
      
      3) There's a whole new decoder included, specifically for the
         not-quite-RC5 15-bit protocol variant used by the Streamzap PC
         Remote. The decoder, while usable with other recievers (tested with
         an mceusb receiver), will only be loaded by the streamzap driver, as
         its likely not of use in almost all other situations. This can be
         revisited if/when all keytable loading (and disabling of unneeded
         protocol decoder engines) is moved to userspace, but for now, I think
         this makes the most sense.
      
      Note that I did try to enable handling the streamzap RC5-ish protocol in
      the current RC5 decoder, but there's no particularly easy way to tell if
      its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
      in testing an attempted decoder merge, only 2/3 of the keys were
      properly recognized as being the 15-bit variant and decoded correctly,
      the rest were close enough to compliant with 14-bit that they were
      decoded as such (but they have overlap with one another, and thus we
      can't just shrug and use the 14-bit decoded values).
      
      Also of note in this patch is the removal of the streamzap driver's
      internal delay buffer. Per discussion w/Christoph, it shouldn't be
      needed by lirc any longer anyway, and it doesn't seem to make any
      difference to the in-kernel decoder engine. That being the case, I'm
      yanking it all out, as it greatly simplifies the driver code.
