  • 37cce26b3   PM / VT: Cleanup #if defined uglyness and fix compile error ... Browse Code »

    Introduce the config option CONFIG_VT_CONSOLE_SLEEP in order to cleanup
    the #if defined ugliness for the vt suspend support functions. Note that
    CONFIG_VT_CONSOLE is already dependant on CONFIG_VT.

    The function pm_set_vt_switch is actually dependant on CONFIG_VT and not
    CONFIG_PM_SLEEP. This fixes a compile error when CONFIG_PM_SLEEP is
    not set:

    drivers/tty/vt/vt_ioctl.c:1794: error: redefinition of 'pm_set_vt_switch'
    include/linux/suspend.h:17: error: previous definition of 'pm_set_vt_switch' was here

    Also, remove the incorrect path from the comment in console.c.

    [rjw: Replaced #if defined() with #ifdef in suspend.h.]

  • 5ada918b8   vt: introduce and use vt_kmsg_redirect() function ... Browse Code »

    The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to
    redirect the kernel messages to a specific console.

    However, since it's not possible to switch to the kernel message console
    after a panic(), it would be nice if the kernel would print the panic
    message on the current console.

    This patch series adds a new interface to access the global kmsg_redirect
    variable by a function to be able to use it in code where
    CONFIG_VT_CONSOLE is not set (kernel/panic.c).

    This patch:

    Instead of using and exporting a global value kmsg_redirect, introduce a
    function vt_kmsg_redirect() that both can set and return the console where
    messages are printed.

    Change all users of kmsg_redirect (the VT code itself and kernel/power.c)
    to the new interface.

    The main advantage is that vt_kmsg_redirect() can also be used when
    CONFIG_VT_CONSOLE is not set.

    In the past someone gratuitiously borrowed chunks of kernel internal vt
    code and dumped them in kernel/power. They have all sorts of deep relations
    with the vt code so put them in the vt tree instead

    Avoids later waking up to a blinking cursor if the device woke up and
    returned to sleep before the console switch happened.

  • b6f448e99   PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switch ... Browse Code »

    Prior to suspend, we allocate and switch to a new VT; after suspend, we switch
    back to the original VT. This can be slow, and is completely unnecessary if
    the framebuffer we're using can restore video properly.

    This adds a hook that allows drivers to select whether or not to do this vt
    switch, and changes the gxfb driver to call this hook. It also adds a module
    param to gxfb to allow controlling of the vt switch (defaulting to no switch).

    (Note: I'm not convinced that console_sem is the best way to protect this, but
    we should probably have some form of locking..)

  • b257bc051   [PATCH] swsusp: fix suspend when console is in VT_AUTO+KD_GRAPHICS mode ... Browse Code »

    When the console is in VT_AUTO+KD_GRAPHICS mode, switching to the
    SUSPEND_CONSOLE fails, resulting in vt_waitactive() waiting indefinitely or
    until the task is interrupted. This patch tests if a console switch can
    occur in set_console() and returns early if a console switch is not
    possible.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
