Subject: [PATCH v2 00/27] Add support for OpenCAPI SCM devices
Date: Tue, 3 Dec 2019 14:46:28 +1100 [thread overview]
Message-ID: <20191203034655.51561-1-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.
V2:
- "powerpc: Map & release OpenCAPI LPC memory"
- Fix #if -> #ifdef
- use pci_dev_id to get the bdfn
- use __be64 to hold be data
- indent check_hotplug_memory_addressable correctly
- Remove export of check_hotplug_memory_addressable
- "ocxl: Conditionally bind SCM devices to the generic OCXL driver"
- Improve patch description and remove redundant default
- "nvdimm: Add driver for OpenCAPI Storage Class Memory"
- Mark a few funcs as static as identified by the 0day bot
- Add OCXL dependancies to OCXL_SCM
- Use memcpy_mcsafe in scm_ndctl_config_read
- Rename scm_foo_offset_0x00 to scm_foo_header_parse & add docs
- Name DIMM attribs "ocxl" rather than "scm"
- Split out into base + many feature patches
- "powerpc: Enable OpenCAPI Storage Class Memory driver on bare metal"
- Build DEV_DAX & friends as modules
- "ocxl: Conditionally bind SCM devices to the generic OCXL driver"
- Patch dropped (easy enough to maintain this out of tree for development)
- "ocxl: Tally up the LPC memory on a link & allow it to be mapped"
- Add a warning if an unmatched lpc_release is called
- "ocxl: Add functions to map/unmap LPC memory"
- Use EXPORT_SYMBOL_GPL
Alastair D'Silva (27):
memory_hotplug: Add a bounds check to __add_pages
nvdimm: remove prototypes for nonexistent functions
powerpc: Add OPAL calls for LPC memory alloc/release
mm/memory_hotplug: Allow check_hotplug_memory_addressable to be called
from drivers
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
ocxl: Free detached contexts in ocxl_context_detach_all()
nvdimm: Add driver for OpenCAPI Storage Class Memory
nvdimm/ocxl: Add register addresses & status values to header
nvdimm/ocxl: Read the capability registers & wait for device ready
nvdimm/ocxl: Add support for Admin commands
nvdimm/ocxl: Add support for near storage commands
nvdimm/ocxl: Register a character device for userspace to interact
with
nvdimm/ocxl: Implement the Read Error Log command
nvdimm/ocxl: Add controller dump IOCTLs
nvdimm/ocxl: Add an IOCTL to report controller statistics
nvdimm/ocxl: Forward events to userspace
nvdimm/ocxl: Add an IOCTL to request controller health & perf data
nvdimm/ocxl: Support firmware update via sysfs
nvdimm/ocxl: Implement the heartbeat command
nvdimm/ocxl: Add debug IOCTLs
nvdimm/ocxl: Implement Overwrite
nvdimm/ocxl: Expose SMART data via ndctl
powerpc: Enable OpenCAPI Storage Class Memory driver on bare metal
