  • a03d63880   net: Make sure the ethaddr is updated in net_init() ... Browse Code »

    NetConsole may call NetSendUDPPacket before NetLoop is called. This
    will cause the source MAC address (NetOurEther) to be wrong. Instead
    of only changing it in NetLoop, move it to NetLoopInit so that it is
    also updated when net_init() is called (especially by nc_start()).

  • 1b4bd0e66   usb_storage: fix ehci driver max transfer size ... Browse Code »

    The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage:
    Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in
    usb_storage as it wrongly assumes that every transfer can use
    4096 bytes per qt_buffer. This is wrong if the start address of
    the data is not page aligned to 4096 bytes and leads to 'EHCI
    timed out on TD' messages because of 'out of buffer pointers'
    in ehci_td_buffer function.

    The bug appears during load of a fragmented file and
    read from or write to an unaligned memory address.

    Align buffers passed to the USB code to cache line size so
    they can be DMAed safely.

  • 80ab414af   usb: pass cache-aligned buffer to usb_get_descriptor() ... Browse Code »

    usb_get_descriptor passes it's buffer argument directly to
    usb_control_msg() so it has to be properly aligned/padded.

  • 189a6956e   ehci-hcd: fix external buffer cache handling ... Browse Code »

    Buffer coming from upper layers should be cacheline aligned/padded
    to perform safe cache operations. For now we don't do bounce
    buffering so getting unaligned buffer is an upper layer error.
    We can't check if the buffer is properly padded with current
    interface so just assume it is (consider changing with in the
    future). The following changes are done:

    1. Remove useless length alignment check. We get actual transfer
    length not the size of the underlying buffer so it's perfectly
    valid for it to be unaligned.
    2. Move flush_dcache_range() out of while loop or it will
    flush too much.
    3. Don't try to fix buffer address before calling invalidate:
    if it's unaligned it's an error anyway so let cache subsystem
    cry about that.
    4. Fix end buffer address to be cacheline aligned assuming upper
    layer reserved enough space. This is potentially dangerous
    operation so upper layers should be careful about that.

  • 71c5de4f4   ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignment ... Browse Code »

    The USB spec says that 32 bytes is the minimum required alignment.
    However on some platforms we have a larger minimum requirement for cache
    coherency. In those cases, use that value rather than the USB spec
    minimum. We add a cpp check to to define USB_DMA_MINALIGN and
    make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here
    as we are not allowed to have tests inside of align(...).

    [ilya.yanok]: moved external buffer fixes to separate patch,
    we use {ALLOC,DEFINE}_ALIGN_BUFFER macros with alignment of USB_DMA_MINALIGN
    for qh_list, qh and qtd structures to make sure they are proper aligned
    for both controller and cache operations.

  • c7701af59   ehci-hcd: program asynclistaddr before every transfer ... Browse Code »

    Move or_asynclistaddr programming to ehci_submit_async()
    function to make sure queue head is properly programmed
    before every transfer. This solves the problem with changing
    qh address.

    Also remove unneeded qh_list->qh_link reprogramming at the
    end of transfer.
