Apple MacBook Pro 11,5

This configuration will not work with MacBook Pro 11,2 or 11,3 models.

Notable features

• Prevent intermittent USB 3.0 controller wakeup signal when the lid is closed. Without this fix your laptop may get very hot and drain the battery after waking up in your laptop bag.

  You can see for yourself which devices are allowed to wake up your laptop using the command:

  cat /proc/acpi/wakeup
  

  This fix works for Linux kernel 3.13 and above.

Graphics

The MacBookPro11,4 and MacBookPro11,5 models ship with a discrete ATI/AMD graphics card (whereas MacBookPro11,2 and MacBookPro11,3 ship with NVidia cards). This is alongside the usual integrated Intel GPU.

You may wish to look into dynamic switching between integrated and discrete graphics, but this config doesn't attempt it.

Currently this uses the experimental si_support to disable the older radeon driver and enable the more modern amdgpu driver.
