  • e0059eaef   usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driver ... Browse Code »

    The Samsung's UDC driver is not anymore copying data from USB requests to
    aligned internal buffers. Now it works directly in data allocated in the
    upper layers like UMS, DFU, THOR.

    This change is possible since those gadgets now must take care to allocate
    buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE).

    This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or
    ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer
    aligned to cache line in both starting address and its size.
    Sometimes it is enough to just use memalign() with size being a
    multiplication of cache line size.

    Test condition
    - test HW + measurement: Trats - Exynos4210 rev.1
    - test HW Trats2 - Exynos4412 rev.1
    400 MiB compressed rootfs image download with `thor 0 mmc 0`

    Measurement:
    Transmission speed: 27.04 MiB/s

  • 6777a3cf7   lin_gadget: use common linux/compat.h ... Browse Code »

    Merge our duplicate definitions with the common header.

    Also fix drivers/usb/gadget/s3c_udc_otg_xfer_dma.c to
    use min() instead of min_t() since we remove the latter
    from compat.h.

    Additionally use memalign() directly as the lin_gadget
    specific kmalloc() macro is removed from lin_gadget_compat.h
    by this patch.

  • b2fb47f18   USB: Use (get|put)_unaligned for accessing wMaxPacketSize ... Browse Code »

    In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase
    where the previous behavior of leaving wMaxPacketSize be unaligned
    caused fatal problems. The initial fix for this problem was incomplete
    however as it showed another cases of non-aligned access that previously
    worked implicitly. This switches to making sure that all access of
    wMaxPacketSize are done via (get|put)_unaligned.

    In order to maintain a level of readability to the code in some cases
    we now use a variable for the value of wMaxPacketSize and in others, a
    macro.
