      HID: hid-lg4ff: Set absolute axes parametes on DFP · a2063172
      Michal Malý 提交于
      The lg4ff driver doesn't fill the "input_absinfo" struct so it is left
      with default values. Applications with rely on information in this struct
      therefore do not work correctly with the wheel.
      
      Other Logitech wheels probably need this fix too, but again I do not have
      enough information to write it.

      HID: hid-lg4ff: Adjust X axis input value accordingly to selected range. · 2b24a960
      Michal Malý 提交于
      Range limiting command for the Driving Force Pro wheel is only a FF_SPRING
      effect so that the wheel creates resistance when the user tries to turn it past
      the limit. It is however possible to overpower the FFB motors quite easily which
      leads to the X axis value exceeding the expected limit. This confuses
      games which dynamically adjust calibration using the highest/lowest min and max
      values reported by the wheel. Joydev device driver also doesn't take in account
      any changes in an axis range after the joystick device is created.
      
      This patch recalculates received ABS_X axis value so it is always in
      <0; 16383> range where 0 is the left limit and 16383 the right limit.
      Logitech driver for Windows does the same thing.  As for any concerns about
      possible loss of precision, I compared a large set of raw/adjusted values
      generated by "mult_frac" to values returned by the Windows driver and I got
      a 100% match.
      
      Other Logitech wheels will probably need a similar fix, but I currently lack
      the information needed to write one.

      Marc Kleine-Budde 提交于
      This patch fixes an oops which occurs when unloading the driver, while the
      network interface is still up. The problem is that first the io mapping is
      teared own, then the CAN device is unregistered, resulting in accessing the
      hardware's iomem:

      net: do not disable sg for packets requiring no checksum · c0d680e5
      Ed Cashin 提交于
      A change in a series of VLAN-related changes appears to have
      inadvertently disabled the use of the scatter gather feature of
      network cards for transmission of non-IP ethernet protocols like ATA
      over Ethernet (AoE).  Below is a reference to the commit that
      introduces a "harmonize_features" function that turns off scatter
      gather when the NIC does not support hardware checksumming for the
      ethernet protocol of an sk buff.
      
        commit f01a5236
        Author: Jesse Gross <jesse@nicira.com>
        Date:   Sun Jan 9 06:23:31 2011 +0000
      
            net offloading: Generalize netif_get_vlan_features().
      
      The can_checksum_protocol function is not equipped to consider a
      protocol that does not require checksumming.  Calling it for a
      protocol that requires no checksum is inappropriate.
      
      The patch below has harmonize_features call can_checksum_protocol when
      the protocol needs a checksum, so that the network layer is not forced
      to perform unnecessary skb linearization on the transmission of AoE
      packets.  Unnecessary linearization results in decreased performance
      and increased memory pressure, as reported here:
      
        http://www.spinics.net/lists/linux-mm/msg15184.html
      
      The problem has probably not been widely experienced yet, because
      only recently has the kernel.org-distributed aoe driver acquired the
      ability to use payloads of over a page in size, with the patchset
      recently included in the mm tree:
      
        https://lkml.org/lkml/2012/8/28/140
      
      The coraid.com-distributed aoe driver already could use payloads of
      greater than a page in size, but its users generally do not use the
      newest kernels.
