      [PATCH] dell_rbu: changes in packet update mechanism · ad6ce87e
      Abhay Salunke authored
      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.

      [PATCH] dell_rbu: enhancements and fixes · e61c0e33
      Abhay Salunke authored
      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.
