Message-ID: <20210701201005.3065299-1-vishal.l.verma@intel.com> (raw)
Changes since v2[1]:
- Some minor cleanups and formatting (Ben)
- Update cxl_mem.h to the latest kernel version (Ben)
- Add .clang-format (Ben)
- Add label commands to cxl-clu - {read,write,zero}-labels
- Add libcxl and cxl-cli to the RPM spec

These patches add a new utility and library to support CXL devices.
This comprehends the kernel's sysfs layout for CXL devices, and
implements a command submission harness for CXL mailbox commands via
ioctl()s definied by the cxl_mem driver.
These patches include:
- libcxl representation of cxl_mem devices
- A command submission harness through libcxl
- A 'cxl-list' command which displays information about a device
- cxl-{read,write,zero}-labels commands for Label Storage Area
manipulation
- Unit tests to exercise several libcxl APIs and perform mailbox
commands.
Patch 15 is an RFC - maybe this should just be dropped entirely for now
until there is a concept of active/disabled memdevs. It is useful as a
placeholder as it allows for a way to pre-insert checks in places
we expect the device to be active or disabled.
An ndctl branch with these patches is also available at [2]
