The code for this feature is available in kernel 4.16-rc1, and we'd like to 
backport the following 13 patches for 18.04. They should apply cleanly on a 
4.15 kernel:

228c2f410378 powerpc/powernv: Set correct configuration space size for opencapi 
74d656d219b9 powerpc/powernv: Add opal calls for opencapi
6914c757118e powerpc/powernv: Add platform-specific services for opencapi
2cb3d64b2698 powerpc/powernv: Capture actag information for the device
5ef3166e8a32 ocxl: Driver code for 'generic' opencapi devices
aeddad1760ae ocxl: Add AFU interrupt support
280b983ce2b8 ocxl: Add a kernel API for other opencapi drivers
92add22e8478 ocxl: Add trace points
b97f02246e0d ocxl: Add Makefile and Kconfig

Bug description:
  [FEATURE] OpenCAPI enabling

  OpenCAPI is an Open Interface Architecture that allows any
  microprocessor to attach to

    *  Coherent user-level accelerators and I/O devices
    *  Advanced memories accessible via read/write or user-level DMA semantics
    *  Agnostic to processor architecture

  This is a feature to enable OpenCapi on Ubuntu 18.04. This is planned to be 
included in 4.16 and it will need to be backported to 4.15:
