Subject: [PATCH 00/10] Add support for OpenCAPI SCM devices
Date: Fri, 25 Oct 2019 15:46:55 +1100 [thread overview]
Message-ID: <20191025044721.16617-1-alastair@au1.ibm.com> (raw)
From: Alastair D'Silva <alastair@d-silva.org>
This series adds support for OpenCAPI SCM devices, exposing
them as nvdimms so that we can make use of the existing
infrastructure.
The first patch (in memory_hotplug) has reviews/acks, but has
not yet made it upstream.
Alastair D'Silva (10):
memory_hotplug: Add a bounds check to __add_pages
nvdimm: remove prototypes for nonexistent functions
powerpc: Add OPAL calls for LPC memory alloc/release
powerpc: Map & release OpenCAPI LPC memory
ocxl: Tally up the LPC memory on a link & allow it to be mapped
ocxl: Add functions to map/unmap LPC memory
ocxl: Save the device serial number in ocxl_fn
nvdimm: Add driver for OpenCAPI Storage Class Memory
powerpc: Enable OpenCAPI Storage Class Memory driver on bare metal
ocxl: Conditionally bind SCM devices to the generic OCXL driver
