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]
