  • 1855256c4   drivers/firmware: const-ify DMI API and internals ... Browse Code »

    Three main sets of changes:

    1) dmi_get_system_info() return value should have been marked const,
    since callers should not be changing that data.

    2) const-ify DMI internals, since DMI firmware tables should,
    whenever possible, be marked const to ensure we never ever write to
    that data area.

    3) const-ify DMI API, to enable marking tables const where possible
    in low-level drivers.

    And if we're really lucky, this might enable some additional
    optimizations on the part of the compiler.

    The bulk of the changes are #2 and #3, which are interrelated. #1 could
    have been a separate patch, but it was so small compared to the others,
    it was easier to roll it into this changeset.

    Reduces the polling frequency from 10 Hz to 2 Hz, which should be less a burden
    for laptops wrt energy saving. As it is multimedia keys, 500ms (maximum) of
    latency should be still fine for the user. In order to keep fluent the feeling
    when the user is pressing several keys in a raw (such as changing the volume),
    the frequency is increased for a short duration after a key is pressed.

    declaring all keymaps as __initdata and copying right keymap
    during DMI detection. On x86 this make the module size at
    runtime going from 10616 to 9428: a bit more than 1kb saved.

    It turns out that the keymaps in the wistron driver are almost the
    same, the main difference being some keys which may not exist and
    leds which might not be present. Therefore it's possible to write
    a generic keymap which would allow the use of an unknown keyboard
    with little drawbacks. The user can select it specifying the parameter
    "keymap=generic".

  • 6480e2a27   Input: wistron - add acerhk laptop database ... Browse Code »

    Acerhk supports already a lot of laptops. Lets import its database so
    that everyone can benefit of the work of Olaf Tauber. Only the "tm_new"
    laptops were imported. "tm_old" laptops could be possible but requires
    more testing and probably only few laptops are still alive. "dritek"
    laptops should probably be imported into a different driver. Also compress
    the keymaps by fitting each entry on an int. Most of the dmi matching was
    written based on google searches, so it's rather prone to errors. That's
    why I'm asking people to confirm it works.

    Support to generate switch input events was added as some laptops indicate
    lid open/close through this interface.

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential

    these shared resources.

  • 5d469ec0f   [PATCH] Correct misc_register return code handling in several drivers ... Browse Code »

    Clean up several code points in which the return code from misc_register is
    not handled properly.

    Several modules failed to deregister various hooks when misc_register fails,
    and this patch cleans them up. Also there are a few modules that legitimately
    don't care about the failure status of misc register. These drivers however
    unilaterally call misc_deregister on module unload.

    Since misc_register doesn't initialize the list_head in the init_routine if it
    fails, the deregister operation is at risk for oopsing when list_del is
    called. The initial solution was to manually init the list in the miscdev
    structure in each of those modules, but the consensus in this thread was to
    consolodate and do that universally inside misc_register.

  • 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.
