    Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

    AT91sam9g20 is an evolution of the at91sam9260 with a faster clock
    speed.
    We created a new board for this device but based the chip support
    directly on 9260 files with little updates.

  • 08cbc706a   USB: at91_udc: correct hanging while disconnecting usb cable ... Browse Code »

    Correct hanging while disconnecting the USB device cable. Prevent a race
    between vbus and UDP interrupts. This bug was tracked on at91sam9260ek
    boards.

    A usb resume interrupt was firing after the vbus interrupt : the IP was
    then already stoped and not able to deal with it (no more clock). A simple
    interrupt disabling is ok as the "end of bus reset" irq is non maskable and
    ok to resume the USB device IP.

  • c67ab134b   usb gadget stack: remove usb_ep_*_buffer(), part 2 ... Browse Code »

    This patch removes controller driver infrastructure which supported
    the now-removed usb_ep_{alloc,free}_buffer() calls.

    As can be seen, many of the implementations of this were broken to
    various degrees. Many didn't properly return dma-coherent mappings;
    those which did so were necessarily ugly because of bogosity in the
    underlying dma_free_coherent() calls ... which on many platforms
    can't be called from the same contexts (notably in_irq) from which
    their dma_alloc_coherent() sibling can be called.

    The main potential downside of removing this is that gadget drivers
    wouldn't have specific knowledge that the controller drivers have:
    endpoints that aren't dma-capable don't need any dma mappings at all.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

    - Couple handling of both type of wakeup events, to be more direct. The

  • 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.
