  • ad6ce87e5   [PATCH] dell_rbu: changes in packet update mechanism ... Browse Code »

    In the current dell_rbu code ver 2.0 the packet update mechanism makes the
    user app dump every individual packet in to the driver.

    This adds in efficiency as every packet update makes the
    /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear
    again. Thus the user app needs to wait for the files to reappear to dump
    another packet. This slows down the packet update tremendously in case of
    large number of packets. I am submitting a new patch for dell_rbu which will
    change the way we do packet updates;

    In the new method the user app will create a new single file which has already
    packetized the rbu image and all the packets are now staged in this file.

    This driver also creates a new entry in
    /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet
    size here before downloading the packet file.

    The user should do the following:

    create one single file which has all the packets stacked together.
    echo the packet size in to /sys/devices/platform/dell_rbu/packet_size.
    echo 1 > /sys/class/firmware/dell_rbu/loading
    cat the packetfile > /sys/class/firmware/dell_rbu/data
    echo 0 > /sys/class/firmware/dell_rbu/loading

    The driver takes the file which came through /sys/class/firmware/dell_rbu/data
    and takes chunks of paket_size data from it and place in contiguous memory.

    This makes packet update process very efficient and fast. As all the packet
    update happens in one single operation. The user can still read back the
    downloaded file from /sys/devices/platform/dell_rbu/data.

  • e61c0e336   [PATCH] dell_rbu: enhancements and fixes ... Browse Code »

    BUG fixes:

    The driver used to allocate memory with spinlock held which has been
    fixed in this patch.

    The driver was printing the entire buffer when it received a invalid
    entry in image_type. The fix is to only print a warning message and not
    the buffer.

    Usability enhancements:

    It is possible that due to user error the /sys/class/firmware/dell_rbu
    entries might be missing, this can happen if the user does the following

    echo 1 > /sys/class/firmware/dell_rbu/loading
    echo 0 > /sys/class/firmware/dell_rbu/loading

    This will make the entries in /sys/class/firmware/ to disappear and the
    only way get them back was bby unloading and loading the driver.

    This patch makes the user recreate these entries by echoing init in to
    image_type.

    This patch has been tested with Libsmbios and Dell OpenManage.

  • f62c4a96f   [IA64] Make PCDP work again. ... Browse Code »

    Mark's patch added "attribute((packed))" for pcdp_uart, without
    accounting for the fact that the structure definition _relied_ on
    implicit padding by 6 bytes. Fix is to make the padding explicit.

  • 66b7f8a30   [IA64-SGI] pcdp: add PCDP pci interface support ... Browse Code »

    Resend 2 with changes per Bjorn Helgaas comments. Changes from original:

    + Change globals to vga_console_iobase/vga_console_membase and make them
    unconditional.
    + Address style-related comments.

    Patch to extend the PCDP vga setup code to support PCI io/mem translations
    for the legacy vga ioport and ram spaces on architectures (e.g. altix) which
    need them.

    Summary of the changes:

    drivers/firmware/pcdp.c
    drivers/firmware/pcdp.h
    -----------------------
    + add declaration for the spec-defined PCI interface struct (pcdp_if_pci)
    as well as support macros.

    + extend setup_vga_console() to know about pcdp_if_pci and add a couple of
    globals to hold the io and mem translation offsets if present.

    arch/ia64/kernel/setup.c
    ------------------------
    + tweek early_console_setup() to allow multiple early console setup routines
    to be called.

    include/asm-ia64/vga.h
    ----------------------
    + make VGA_MAP_MEM vga_console_membase aware

    Here's a patch with kfree() cleanups for drivers/firmware/efivars.c Patch
    removes redundant NULL checks before kfree and also makes a small
    whitespace cleanup - moves two statements on same line to separate lines.

  • 280dedb8d   [PATCH] PCDP: handle tables that don't supply baud rate ... Browse Code »

    The HCDP specs (i.e., PCDP revision < 3) allow zero as a default value for
    baud rate and data bits. So if firmware doesn't supply them, let
    early_serial_console_init() probe for them rather than telling it the baud
    rate is zero.

    Also, update the URL for the PCDP spec.

    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!
