definitions.: + +**mi.h - NVMe Management Interface library (libnvme-mi) definitions.** + + +These provide an abstraction for the MI messaging between controllers +and a host, typically over an MCTP-over-i2c link to a NVMe device, used +as part of the out-of-band management of a system. + +We have a few data structures define here to reflect the topology +of a MI connection with an NVMe subsystem: + + - :c:type:`nvme_mi_ep_t`: an MI endpoint - our mechanism of communication with a + NVMe subsystem. For MCTP, an endpoint will be the component that + holds the MCTP address (EID), and receives our request message. + + endpoints are defined in the NVMe-MI spec, and are specific to the MI + interface. + + Each endpoint will provide access to one or more of: + + - :c:type:`nvme_mi_ctrl_t`: a NVMe controller, as defined by the NVMe base spec. + The controllers are responsible for processing any NVMe standard + commands (eg, the Admin command set). An endpoint (:c:type:`nvme_mi_ep_t`) + may provide access to multiple controllers - so each of the controller- + type commands will require a :c:type:`nvme_mi_ctrl_t` to be specified, rather than + an endpoint + +A couple of conventions with the libnvme-mi API: + + - All types and functions have the nvme_mi prefix, to distinguish from + the libnvme core. + + - We currently support either MI commands and Admin commands. The + former adds a _mi prefix, the latter an _admin prefix.

This value is the 8-bit MI status + value, represented by :c:type:`enum nvme_mi_resp_status <nvme_mi_resp_status>`. Note that the + status values may be vendor-defined above 0xe0. + +For the second case, we have a few conventions for errno values: + + - EPROTO: response data violated the MI protocol, and libnvme cannot + validly interpret the response + + - EIO: Other I/O error communicating with device (eg., valid but + unexpected response data) + + - EINVAL: invalid input arguments for a command + +In line with the core NVMe API, the Admin command functions take an +`_args` structure to provide the command-specific parameters.

Note that the original string, +**kv**, gets modified. + + +.. c:function:: char * kv_keymatch (const char *kv, const char *key) + + Look for key in key value string + +**Parameters** + +``const char *kv`` + The key=value string to search for the presence of **key** + +``const char *key`` + The key to look for + +**Description** + +Look for **key** in the Key=Value pair pointed to by **k** and return a +pointer to the Value if **key** is found. + +Check if **kv** starts with **key**. If it does then make sure that we +have a whole-word match on the **key**, and if we do, return a pointer +to the first character of value (i.e. skip leading spaces, tabs, +and equal sign) + +**Return** + +A pointer to the first character of "value" if a match is found. +NULL otherwise. + + +.. c:function:: char * startswith (const char *s, const char *prefix) + + Checks that a string starts with a given prefix. + +**Parameters** + +``const char *s`` + The string to check + +``const char *prefix`` + A string that **s** could be starting with + +**Return** + +If **s** starts with **prefix**, then return a pointer within **s** at +the first character after the matched **prefix**.

In order to +move to the next element in the array one must increment the +pointer to the current element (**p**) by the size of the current +element. + +**Return** + +Pointer to the next element in the array. + + + + +.. c:enum:: nvme_version + + Selector for version to be returned by **nvme_get_version** + +**Constants** + +``NVME_VERSION_PROJECT`` + Project release version + +``NVME_VERSION_GIT`` + Git reference + + +.. c:function:: const char * nvme_get_version (enum nvme_version type) + + Return version libnvme string + +**Parameters** + +``enum nvme_version type`` + Selects which version type (see **struct** nvme_version) + +**Return** + +Returns version string for known types or else "n/a" + + diff --git a/doc/update-docs.sh b/doc/update-docs.sh index 7765b9b..dfa1fd8 100755 --- a/doc/update-docs.sh +++ b/doc/update-docs.sh @@ -1,8 +1,11 @@ -#!/bin/sh -x +#!/bin/sh +# SPDX-License-Identifier: LGPL-2.1-or-later DESTDIR=$(pwd) +# build man docs BUILDDIR="$(mktemp -d)" +echo $BUILDDIR trap 'rm -rf -- $BUILDDIR' EXIT meson $BUILDDIR -Ddocs=man -Ddocs-build=true @@ -13,6 +16,25 @@ mkdir $DESTDIR/doc/man find $BUILDDIR/doc -maxdepth 1 -name '*.2' -exec cp {} $DESTDIR/doc/man \; +# build ReST docs +rm -rf -- $BUILDDIR +BUILDDIR="$(mktemp -d)" +echo $BUILDDIR +trap 'rm -rf -- $BUILDDIR' EXIT + +meson $BUILDDIR -Ddocs=rst -Ddocs-build=true +ninja -C $BUILDDIR + +rm -rf $DESTDIR/doc/rst/*.rst +mkdir -p $DESTDIR/doc/rst + +find $BUILDDIR/doc/rst -maxdepth 1 -name '*.rst' -exec cp {} $DESTDIR/doc/rst \; + +cp $BUILDDIR/doc/conf.py $DESTDIR/doc +cp $BUILDDIR/doc/index.rst $DESTDIR/doc +cp $BUILDDIR/doc/config-schema.json $DESTDIR/doc + +# build html docs # The HTML doc is not ready yet # rm -rf $DESTDIR/doc/html # cp -R $BUILDDIR/doc/html $DESTDIR/doc/ |
