  • 0491d1f3f   IOC3: Program UART predividers. ... Browse Code »

    The IOC3 driver's UART detection bits used to rely on the the firmware
    setting the UART pre-divider in a way that's apropriate for the 8250
    driver which doesn't currently program this register. This happens
    to work for the console but not rarely for additional ports.

    While at it, also program the UART to RS-232 PIO mode; it the UART might
    have been in mac-serial and/or DMA mode though that hasn't actually been
    observed in practice.

  • f49343a54   IOC3: Switch to pci refcounting safe APIs ... Browse Code »

    Convert the IOC3 driver to use ref counting pci interfaces so that we can
    obsolete the (usually unsafe) pci_find_{slot/device} interfaces and avoid
    future authors writing hotplug-unsafe device drivers.

  • f0ba73583   Fix link autonegotiation timer. ... Browse Code »

    Start link negotiation in the open method. Previously it was started
    on driver initialialization and shutdown on close so an ifdown would
    have results in closing negotiation for good.

  • cfadbd298   [PATCH] Fix timer race ... Browse Code »

    When closing the driver or reinitializing the hardware there is the
    usual del_timer() race condition that exists when timers re-add
    themselves. Fix by conversion to del_timer_sync().

  • 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.

  • d5b20697c   [PATCH] Remove more unnecessary driver printk's ... Browse Code »

    As I promised last week, here is the first pass at removing all
    unnecessary printk's that exist in network device drivers currently in
    promiscuous mode. The duplicate messages are not needed so they have
    been removed. Some of these drivers are quite old and might not need an
    update, but I did them all anyway.

    I am currently auditing the remaining conditional printk's and will send
    out a patch for those soon.

    - Using the right register clearly improves chances of getting the MII
    code and thus the driver working at all.
    - On startup check the media type before setting up duplex or we might
    spend the first 1.2s with a wrong duplex setting.
    - Get rid of whitespace lines.

    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!
