Subject: [ndctl PATCH v5 00/16] Initial CXL support
Date: Thu, 11 Nov 2021 13:44:20 -0700 [thread overview]
Message-ID: <20211111204436.1560365-1-vishal.l.verma@intel.com> (raw)
Changes since v4[1]:
- Collect review tags
- Handle the case where label_size > payload_max. With cxl_test labels
being 128K, it was easy to hit this case, so add in the handling to
loop over the label space in payload_max sized chunks to read/write the
full label area.
- Make label APIs consistent for what size==0 means (Dan)
- Introduce an nvdimm bridge object, and an API to check whether one is
active, replacing the stub 'cxl_memdev_is_active() API) (Dan)
- Import Linux's FIELD_GET() and use it for health_info accessors (Dan)
- Move all symbols to the v1 group in libcxl.sym since this is the first
release (Dan)
- Replace the implicit cmd struct casting via (void *) with explicit
casts to the respective structs (Dan).
- Various man page fixups (Dan)
- Switch json_object_new_uint64 to json_object_new_int, as the former is
a relatively new API, and unavailable in some distributions of json-c
- Remove error prints for cmd failure in util_cxl_memdev_health_to_json().
The cmd can fail for a number of reasons, we can just skip printing the
json in that case.

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 defined 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
An ndctl branch with these patches is also available at [2]
