ocxl: Provide global MMIO accessors for external drivers

2019-05-02T16:55:02Z

External drivers that communicate via OpenCAPI will need to make MMIO calls to interact with the devices. Signed-off-by: Alastair D'Silva Reviewed-by: Greg Kurz Acked-by: Frederic Barrat Signed-off-by: Michael Ellerman

ocxl: move event_fd handling to frontend

2019-05-02T16:55:02Z

Event_fd is only used in the driver frontend, so it does not need to exist in the backend code. Relocate it to the frontend and provide an opaque mechanism for consumers instead. Signed-off-by: Alastair D'Silva Acked-by: Frederic Barrat Signed-off-by: Michael Ellerman

ocxl: Allow external drivers to use OpenCAPI contexts

2019-05-02T16:55:02Z

Most OpenCAPI operations require a valid context, so exposing these functions to external drivers is necessary. Signed-off-by: Alastair D'Silva Reviewed-by: Greg Kurz Acked-by: Frederic Barrat Signed-off-by: Michael Ellerman

ocxl: Create a clear delineation between ocxl backend & frontend

2019-05-02T16:55:01Z

The OCXL driver contains both frontend code for interacting with userspace, as well as backend code for interacting with the hardware. This patch separates the backend code from the frontend so that it can be used by other device drivers that communicate via OpenCAPI. Relocate dev, cdev & sysfs files to the frontend code to allow external drivers to maintain their own devices. Reference counting on the device in the backend is replaced with kref counting. Move file & sysfs layer initialisation from core.c (backend) to pci.c (frontend). Create an ocxl_function oriented interface for initing devices & enumerating AFUs.
