    The de2104x did a pci_disable_device() in it's close function, but
    the open function never does a pci_enable_device() and assumes that
    the device is already enabled. Considering that downing the interface
    is just a temporary thing the pci_disable_device() isn't a pretty good
    idea and removing it from the close function just fixes the bug.

    This untested patch _should_ fix:
    "(net de2104x) Kernel panic with de2104x tulip driver on boot"
    http://bugzilla.kernel.org/show_bug.cgi?id=3156

    But the bug submitter isn't responding. Same fix has been applied
    to tulip.c (several years ago) and uli526x.c (Feb 2008) drivers.

    [ The panic reported in the bug report was removed in a recently
    (march 2008) accepted patch from Ondrej Zary. ]

    For the operations
    get-tx-csum
    get-sg
    get-tso
    get-ufo
    the default ethtool_op_xxx behavior is fine for all drivers, so we
    permit op==NULL to imply the default behavior.

    This provides a more uniform behavior across all drivers, eliminating
    ethtool(8) "ioctl not supported" errors on older drivers that had
    not been updated for the latest sub-ioctls.

    The ethtool_op_xxx() functions are left exported, in case anyone
    wishes to call them directly from a driver-private implementation --
    a not-uncommon case. Should an ethtool_op_xxx() helper remain unused
    for a while, except by net/core/ethtool.c, we can un-export it at a
    later date.

  • 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.

  • 689be4394   [NET]: Remove gratuitous use of skb->tail in network drivers. ... Browse Code »

    Many drivers use skb->tail unnecessarily.

    In these situations, the code roughly looks like:

    dev = dev_alloc_skb(...);

    [optional] skb_reserve(skb, ...);

    ... skb->tail ...

    But even if the skb_reserve() happens, skb->data equals
    skb->tail. So it doesn't make any sense to use anything
    other than skb->data in these cases.

    Another case was the s2io.c driver directly mucking with
    the skb->data and skb->tail pointers. It really just wanted
    to do an skb_reserve(), so that's what the code was changed
    to do instead.

    Another reason I'm making this change as it allows some SKB
    cleanups I have planned simpler to merge. In those cleanups,
    skb->head, skb->tail, and skb->end pointers are removed, and
    replaced with skb->head_room and skb->tail_room integers.

    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!
