  • b74ca3a89   netdevice: Kill netdev->priv ... Browse Code »

    This is the last shoot of this series.
    After I removing all directly reference of netdev->priv, I am killing
    "priv" of "struct net_device" and fixing relative comments/docs.

    Anyone will not be allowed to reference netdev->priv directly.
    If you want to reference the memory of private data, use netdev_priv()
    instead.
    If the private data is not allocted when alloc_netdev(), use
    netdev->ml_priv to point that memory after you creating that private
    data.

  • 8f15ea42b   netdevice: safe convert to netdev_priv() #part-3 ... Browse Code »

    We have some reasons to kill netdev->priv:
    1. netdev->priv is equal to netdev_priv().
    2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
    netdev_priv() is more flexible than netdev->priv.
    But we cann't kill netdev->priv, because so many drivers reference to it
    directly.

    This patch is a safe convert for netdev->priv to netdev_priv(netdev).
    Since all of the netdev->priv is only for read.
    But it is too big to be sent in one mail.
    I split it to 4 parts and make every part smaller than 100,000 bytes,
    which is max size allowed by vger.

  • c16d11853   [netdrvr] Drivers should not set IFF_* flag themselves ... Browse Code »

    Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
    It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
    it will broken upper layer handle for promisc and allmulti.
    In addition, drivers can use their own hardware programming to make it.
    So do not allow drivers to set IFF_* flags.

    This is a general driver fix, so I didn't split it to pieces and send
    to specific driver maintainers.

    It's been a useless no-op for long enough in 2.6 so I figured it's time to
    remove it. The number of people that could object because they're
    maintaining unified 2.4 and 2.6 drivers is probably rather small.

  • 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.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
