      - Fixed resetting of timeout · 2e9ed6c0
      Dan Ellis authored
        - Fixed sleep and timeout ioctls
        - Fixed initialisation from special field
        OS_RemoveTicker was being called with the wrong handle so not being
      removed.  This was causing timeout behaviour to work incorrectly.
        Sleep and Timeout ioctls weren't reading their reason fields from the ioctl
      block.  They now do, and work!
        Defaults weren't being set correctly from the special field.
        Tested on a RiscPC, and STB.
        Timeouts cause an error and so because of the fileswitch interface will not
      actually return bytes read during that request.  To perform a managed timeout
      in which bytes can be counted during timeout, non-blocking calls must be
      made.  However, bytes have still been copied to the destination buffer
      (although the caller won't know how many).
        There are still 'issues' with special fields.  However, they appear to work
      correctly on the Dual Serial interface.

      Added new IOCTL reason codes and special field flags for sleeping devicefs. · 3a86b4f5
      Dan Ellis authored
        DeviceFS has been enhanced with the ability to cooperate with Taskwindows
      so as to allow multitasking to continue.  Any devicefs stream, if opened
      with the special field entry 'sleep' will issue OS_UpCall 6 when it would
      normally block.  A flag 'timeout' has also been added which will cause the
      stream to issue a timeout error if it has slept for too long.
        These actions can be set using the generic IOCTLs 4 and 5, the former just
      being a logical switch, the latter being the value in centiseconds for which
      to sleep.
        There is also now a generic special field to specify non-blocking which may
      be used as an alternative to the IOCTL.
        Tested on a RiscPC.

      Fixed lr corruption in UpCall handler · aa45b51a
      Dan Ellis authored
        lr was being used as a temporary register to store the buffer handle in
      whilst checking for ownership.  If DeviceFS didn't own the buffer the call
      was being made on, it then used this value in a MOV pc, lr thus going who
      knows where...
        Checked and still works.  Appears to cure previous problem where issuing
      Upcall 8 could cause a branch through zero error.

      Bug fix: DeviceFS was inadvertently enabling interrupts when generating the Upcall to indicate that new data has arrived in an input buffer.
        DeviceFS was using OS_UpCall to generate a UpCall_DeviceRxDataPresent
        upcall for for the wake up event (when data was inserted into a dormant
        receive buffer).
        However, OS_UpCall enables interrupts, contrary to the RISC OS 3 PRM.
        Since it happened within the hardware modem interrupt handler, this is
        quite dangerous and can lead to the modem interrupt handler being
        re-entered, thereby corrupting bytes or putting bytes into the buffer in
        the wrong order.
        SCTransport v0.57 or later is needed if using this version of DeviceFS
        (since earlier versions relied on this incorrect behaviour in DeviceVS).
        Unfortunately, Pace fault 2098 still exists after making this change
        (Chip to Server transactions are very slow in Customer F 8 using a HW modem).

      Another 32-bit fix. · 3a09e401
      Stewart Brodie authored
        The UpCall handler was using MOVEQS pc, lr to pass on the vector in
          some cases.
        Fixed a non-internationalised build bug - missing condition in macro.

      Removed -throwback from ASFLAGS · ac70132b
      Neil Bingham authored
        Added stripdepnd to MkClean
        Replaceed -throwback with ${THROWBACK} so that throwback isn't generated
        in ROM builds, but still works for local test builds.
        Tested on Ursula build.

      32-bit compatibility added. · c453026f
      Stewart Brodie authored
        Also fixed faulty debug code which tried to report the escape state,
          but would have always failed to do.
        Tested Phoebe and 32 machine builds.  Tested on Risc PC.
