  • 9105585d1   ipack: print a hex number after a 0x prefix ... Browse Code »

    It makes the result hard to interpret correctly if a base 10 number is
    prefixed by 0x. So change to a hex number.

  • d41861ca1   tty: Replace ASYNC_INITIALIZED bit and update atomically ... Browse Code »

    Replace ASYNC_INITIALIZED bit in the tty_port::flags field with
    TTY_PORT_INITIALIZED bit in the tty_port::iflags field. Introduce helpers
    tty_port_set_initialized() and tty_port_initialized() to abstract
    atomic bit ops.

    Note: the transforms for test_and_set_bit() and test_and_clear_bit()
    are unnecessary as the state transitions are already mutually exclusive;
    the tty lock prevents concurrent open/close/hangup.

  • 4847cc073   ipoctal: request_irq after configuration ... Browse Code »

    The request for an IRQ handler must be done after whole configuration. This
    was not the case for this driver which request the IRQ in the middle of
    the configuration. Sometimes, it happens that something is not completely
    configured, we recieve an interrupt thus we stumble into troubles in the
    IRQ handler.

  • 968d04e8d   ipoctal: protect only the real critical section ... Browse Code »

    In some conditions (echo or particular sequence of special
    characters), on buffer push, the tty layer calls the write operation
    while we are holding the spinlock. This means deadlock within the same
    process on kernels version < 3.12. It seems not a problem on recent
    kernel, but the patch still valid as locking optimization.

    The protected variables by the spinlock are: xmit_buf, nb_bytes,
    pointer_read and pointer_write. So, this patch reduces the locked area
    in the IRQ handler only to these variables. Most of the code inside the
    locked area in the IRQ handler is not protected elsewhere; it means
    that it is not protected at all.

  • fc8d713ec   drivers/ipack/devices/ipoctal.c: adjust duplicate test ... Browse Code »

    Delete successive tests to the same location. The code tested the result
    of a previous allocation, that itself was already tested. It is changed to
    test the result of the most recent allocation.

    A simplified version of the semantic match that finds this problem is as
    follows: (http://coccinelle.lip6.fr/)

    //
    @s exists@
    local idexpression y;
    expression x,e;

  • 4f73bc4dd   tty: Added a CONFIG_TTY option to allow removal of TTY ... Browse Code »

    The option allows you to remove TTY and compile without errors. This
    saves space on systems that won't support TTY interfaces anyway.
    bloat-o-meter output is below.

    The bulk of this patch consists of Kconfig changes adding "depends on
    TTY" to various serial devices and similar drivers that require the TTY
    layer. Ideally, these dependencies would occur on a common intermediate
    symbol such as SERIO, but most drivers "select SERIO" rather than
    "depends on SERIO", and "select" does not respect dependencies.

    bloat-o-meter output comparing our previous minimal to new minimal by
    removing TTY. The list is filtered to not show removed entries with awk
    '$3 != "-"' as the list was very long.

    There was a bug in the code when managing a GE IP-OCTAL-485 board. The RX would
    be enabled but we have a wrong state in the rx_enable flag.

    Then, if the user changes the terminal settings, RX would not be enabled again.

    "Here's the big tty/serial tree set of changes for 3.8-rc1.

    Contained in here is a bunch more reworks of the tty port layer from
    Jiri and bugfixes from Alan, along with a number of other tty and
    serial driver updates by the various driver authors.

    Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the
    TTY layer, which is much appreciated by me.

    Fixed up some trivial conflicts in the staging tree, due to the fwserial
    driver having come in both ways (but fixed up a bit in the serial tree),
    and the ioctl handling in the dgrp driver having been done slightly
    differently (staging tree got that one right, and removed both
    TIOCGSOFTCAR and TIOCSSOFTCAR).
