Bug Description

It appears we don't set the CONFIG_GPIO_SYSFS on Trusty (or Utopic?) for x86.

By enabled, I mean:


This option (along with a few gpio devices) is needed to enable programming of such things as the I2C Mux through via the CPLDs on some OEM 'whitebox' switches that will leverage Software Defined Networking.

This option can, of course, be set and users can build their own kernels, but, if at all possible they'd like to keep this as stock as they can.

        bool "/sys/class/gpio/... (sysfs interface)"
        depends on SYSFS
          Say Y here to add a sysfs interface for GPIOs.

          This is mostly useful to work around omissions in a system's
          kernel support. Those are common in custom and semicustom
          hardware assembled using standard kernels with a minimum of
          custom patches. In those cases, userspace code may import
          a given GPIO from the kernel, if no kernel driver requested it.

          Kernel drivers may also request that a particular GPIO be
          exported to userspace; this can be useful when debugging.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
