    Several console keyboard maps are broken since

    unicode diacritics support

    because that changeset made k_self consider the value as a latin1
    character when in Unicode mode, which is wrong; k_self should still take
    the console map into account.

  • 41ab4396e   Console keyboard events and accessibility ... Browse Code »

    Some blind people use a kernel engine called Speakup which uses hardware
    synthesis to speak what gets displayed on the screen. They use the
    PC keyboard to control this engine (start/stop, accelerate, ...) and
    also need to get keyboard feedback (to make sure to know what they are
    typing, the caps lock status, etc.)

    Up to now, the way it was done was very ugly. Below is a patch to add a
    notifier list for permitting a far better implementation, see ChangeLog
    above for details.

    You may wonder why this can't be done at the input layer. The problem
    is that what people want to monitor is the console keyboard, i.e. all
    input keyboards that got attached to the console, and with the currently
    active keymap (i.e. keysyms, not only keycodes).

    This adds a keyboard notifier that such modules can use to get the keyboard
    events and possibly eat them, at several stages:

    - keycodes: even before translation into keysym.
    - unbound keycodes: when no keysym is bound.
    - unicode: when the keycode would get translated into a unicode character.
    - keysym: when the keycode would get translated into a keysym.
    - post_keysym: after the keysym got interpreted, so as to see the result
    (caps lock, etc.)

    This also provides access to k_handler so as to permit simulation of
    keypresses.

    There have been issues with non-latin1 diacritics and unicode.
    http://bugzilla.kernel.org/show_bug.cgi?id=7746

    Git 759448f459234bfcf34b82471f0dba77a9aca498 `Kernel utf-8 handling'
    partly resolved it by adding conversion between diacritics and
    unicode. The patch below goes further by just turning diacritics into
    unicode, hence providing better future support. The kbd support can be
    fetched from
    http://bugzilla.kernel.org/attachment.cgi?id=12313

    This was tested in all of latin1, latin9, latin2 and unicode with french
    and czech dead keys.

    Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR
    and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR.

    New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit
    _input_. No, we don't want to store the translation, as it is potentially
    sparse and large.

  • 7f1f86a0d   [PATCH] Fix SAK_work workqueue initialization. ... Browse Code »

    Somewhere in the rewrite of the work queues my cleanup of SAK handling
    got broken. Maybe I didn't retest it properly or possibly the API
    was changing so fast I missed something. Regardless currently
    triggering a SAK now generates an ugly BUG_ON and kills the kernel.

    Thanks to Alexey Dobriyan for spotting this.

    This modifies the use of SAK_work to initialize it when the data
    structure it resides in is initialized, and to simply call
    schedule_work when we need to generate a SAK. I update both
    data structures that have a SAK_work member for consistency.

    All of the old PREPARE_WORK calls that are now gone.

    If we call schedule_work again before it has processed it
    has generated the first SAK it will simply ignore the duplicate
    schedule_work request.

  • 8b6312f4d   [PATCH] vt: refactor console SAK processing ... Browse Code »

    This does several things.
    - It moves looking up of the current foreground console into process
    context where we can safely take the semaphore that protects this
    operation.
    - It uses the new flavor of work queue processing.
    - This generates a factor of do_SAK, __do_SAK that runs immediately.
    - This calls __do_SAK with the console semaphore held ensuring nothing
    else happens to the console while we process the SAK operation.
    - With the console SAK processing moved into process context this
    patch removes the xchg operations that I used to attempt to attomically
    update struct pid, because of the strange locking used in the SAK processing.
    With SAK using the normal console semaphore nothing special is needed.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

    - The variables used are moved into a structure and declared in vt_kern.h
    - A spinlock is added so we don't have SMP races updating the values.
    - Instead of raw pid_t value a struct_pid is used to guard against
    pid wrap around issues, if the daemon to spawn a new console dies.
