  • ac751efa6   console: rename acquire/release_console_sem() to console_lock/unlock() ... Browse Code »

    The -rt patches change the console_semaphore to console_mutex. As a
    result, a quite large chunk of the patches changes all
    acquire/release_console_sem() to acquire/release_console_mutex()

    This commit makes things use more neutral function names which dont make
    implications about the underlying lock.

    The only real change is the return value of console_trylock which is
    inverted from try_acquire_console_sem()

    This patch also paves the way to switching console_sem from a semaphore to
    a mutex.

  • a2a6a822a   tty: use for_each_console() and WARN() on sysfs failures ... Browse Code »

    This fixes the build warnings in the tty code, and uses the proper
    function for iterating over the console devices.

  • c55c63c65   vt: fix issue when fbcon wants to takeover a second time. ... Browse Code »

    With framebuffer handover and multiple GPUs, we get into a
    position where the fbcon unbinds the vesafb framebuffer for GPU 1,
    but we still have a radeon framebuffer bound from GPU 0, so
    we don't unregister the console driver. Then when we tried to bind
    the new radeon framebuffer for GPU1 we never get to the bind
    call as we fail due to the console being registered already.

    This changes the return value to -EBUSY when the driver is
    already registered and continues to bind for -EBUSY.

    tty: add 'active' sysfs attribute to tty0 and console device

    Userspace can query the actual virtual console, and the configured
    console devices behind /dev/tt0 and /dev/console.

    The last entry in the list of devices is the active device, analog
    to the console= kernel command line option.

    The attribute supports poll(), which is raised when the virtual
    console is changed or /dev/console is reconfigured.

  • 47c344d0b   vcs: make proper usage of the poll flags ... Browse Code »

    Kay Sievers pointed out that usage of POLLIN is well defined by POSIX,
    and the current usage here doesn't follow that definition. So let's
    duplicate the same semantics as implemented by sysfs_poll() instead.
