This MCTP link will typically use i2c/SMBus as the +hardware transport, enabling out-of-band management and control over NVMe +devices using a simple SMBus interface. + +The MI interface is compiled into a separate shared object, ``libnvme-mi.so``. + +Most of the MI API is transport-agnostic, except for the endpoint constructor +functions. Once an endpoint object (``nvme_mi_ep_t``) is created, the generic +functions can be used to manage it. + +When endpoints are created (through one of the transport-specific functions, +like ``nvme_mi_open_mctp()``), the endpoint hardware will be probed to +see if any device-specific workarounds ("quirks") are required. This is +implemented as an Identify Controller command, requesting a small amount of +data on controller ID 0. + +To suppress this probe, the ``LIBNVME_MI_PROBE_ENABLED`` environment var can be +set. Values of ``0``, ``false`` and ``disabled`` will disable the probe, and no +quirks will be applied. Other values, or an unset environment variable, will +enable the probe. + +MCTP Transport +-------------- + +The MI API is generally transport-agnostic, but the only currently-supported +transport is MCTP, using the kernel ``AF_MCTP`` socket interface. + +MCTP endpoints are addressed by a (network-id, endpoint-id) pair. Endpoint +IDs (EIDs) are defined by the MCTP standard as an 8-bit value. Since the +address space is somewhat limited, the Linux `AF_MCTP` support allows for +separate MCTP "networks", which provide separate address spaces. These networks +each have a unique ``unsigned int`` as their ID. + +The default Network ID is 1; unless you have configured otherwise, MCTP +endpoints will appear on this network. + +If compiled with D-Bus support, ``libnvme-mi`` can query the system MCTP daemon +("``mctpd``") to find attached NVMe devices, via the ``nvme_mi_scan_mctp()`` +function. Calling this will establish a ``nvme_root_t`` object, populated +with the results of that scan. Use the ``nvme_mi_for_each_endpoint`` macro +to iterate through the scanned endpoints. + +Note that the MCTP daemon is provided separately, as part of the MCTP userspace +tools, at https://github.com/CodeConstruct/mctp . ``mctpd`` is responsible for +discovery and enumeration for MCTP endpoints on the system, and will query +each for its protocol capabilities during enumeration. Consequently, NVMe-MI +endpoints will need to report support for NVMe-MI-over-MCTP (protocol 0x4) in +their supported protocols list (ie., as returned by the MCTP Get Message Type +Support command) in order to be discovered. diff --git a/doc/quickstart.rst.in b/doc/quickstart.rst.in new file mode 100644 index 0000000..d356188 --- /dev/null +++ b/doc/quickstart.rst.in @@ -0,0 +1,5 @@ +========== +Quickstart +========== + +tbd \ No newline at end of file diff --git a/doc/rst/fabrics.rst b/doc/rst/fabrics.rst new file mode 100644 index 0000000..74d04e5 --- /dev/null +++ b/doc/rst/fabrics.rst @@ -0,0 +1,545 @@ +.. _fabrics.h: + +**fabrics.h** + + +Fabrics-specific definitions. + + + +.. c:struct:: nvme_fabrics_config + + Defines all linux nvme fabrics initiator options + +**Definition** + +:: + + struct nvme_fabrics_config { + char *host_traddr;
