The value * associated with this key is a nvlist that follows the device/subsystem * schema node format. The parameters in this node specify the * configuration parameters that are specific to a particular device * driver. * 2) There must be a key with the name IOV_CONFIG_NAME. The value associated * with this key is an nvlist that follows the device/subsystem schema node * format. The parameters in this node specify the configuration * parameters that are applied by the SR-IOV infrastructure. * * DEVICE/SUBSYSTEM SCHEMA NODE * 1) All keys in the device/subsystem schema node are optional. * 2) Each key specifies the name of a valid configuration parameter that may * be applied to the device/subsystem combination specified by this node. * The value associated with the key specifies the format of valid * configuration values, and must be a nvlist in parameter schema node * format. * * PARAMETER SCHEMA NODE * 1) The parameter schema node must contain a key with the name * TYPE_SCHEMA_NAME. The value associated with this key must be a string. * This string specifies the type of value that the parameter specified by * this node must take. The string must have one of the following values: * - "bool" - The configuration value must be a boolean. * - "mac-addr" - The configuration value must be a binary value. In * addition, the value must be exactly 6 bytes long and * the value must not be a multicast or broadcast mac. * - "uint8_t" - The configuration value must be a integer value in * the range [0, UINT8_MAX]. * - "uint16_t" - The configuration value must be a integer value in * the range [0, UINT16_MAX]. * - "uint32_t" - The configuration value must be a integer value in * the range [0, UINT32_MAX]. * - "uint64_t" - The configuration value must be a integer value in * the range [0, UINT64_MAX]. * 2) The parameter schema may contain a key with the name * REQUIRED_SCHEMA_NAME. This key is optional. If this key is present, the * value associated with it must have a boolean type. If the value is true, * then the parameter specified by this schema is a required parameter. All * valid configurations must include all required parameters. * 3) The parameter schema may contain a key with the name DEFAULT_SCHEMA_NAME. * This key is optional. This key must not be present if the parameter * specified by this schema is required. If this key is present, the value * associated with the parent key must follow all restrictions specified by * the type specified by this schema. If a configuration does not supply a * value for the parameter specified by this schema, then the kernel will * apply the value associated with this key in its place. * * The following is an example of a valid schema, as printed by nvlist_dump. * Keys are printed followed by the type of the value in parantheses. The * value is displayed following a colon. The indentation level reflects the * level of nesting of nvlists. String values are displayed between [] * brackets. Binary values are shown with the length of the binary value (in * bytes) followed by the actual binary values. * * PF (NVLIST): * IOV (NVLIST): * num_vfs (NVLIST): * type (STRING): [uint16_t] * required (BOOL): TRUE * device (NVLIST): * type (STRING): [string] * required (BOOL): TRUE * DRIVER (NVLIST): * VF (NVLIST): * IOV (NVLIST): * passthrough (NVLIST): * type (STRING): [bool] * default (BOOL): FALSE * DRIVER (NVLIST): * mac-addr (NVLIST): * type (STRING): [mac-addr] * default (BINARY): 6 000000000000 * vlan (NVLIST): * type (STRING): [uint16_t] * spoof-check (NVLIST): * type (STRING): [bool] * default (BOOL): TRUE * allow-set-mac (NVLIST): * type (STRING): [bool] * default (BOOL): FALSE */ struct pci_iov_schema { void *schema; size_t len; int error; }; /* * SR-IOV configuration is passed to the kernel as a packed nvlist. See nv(3) * for the details of the nvlist API. The expected format of the nvlist is: * * BASIC RULES * 1) All keys are case-insensitive. * 2) No keys that are not specified below may exist at any level of the * config nvlist. * 3) Unless otherwise specified, all keys are optional. It should go without * saying a key being mandatory is transitive: that is, if a key is * specified to contain a sub-nodes that contains a mandatory key, then * the outer key is implicitly mandatory. If a key is mandatory then the * associated value is also mandatory. * 4) Order of keys is irrelevant. * * TOP LEVEL OF CONFIG NVLIST * 1) All keys specified in this section are mandatory. * 2) There must be a top-level key with the name PF_CONFIG_NAME. The value * associated is an nvlist that follows the "device node" format. The * parameters in this node specify parameters that apply to the PF. * 3) For every VF being configured (this is set via the "num_vfs" parameter * in the PF section), there must be a top-level key whose name is VF_PREFIX * immediately followed by the index of the VF as a decimal integer. For * example, this would be VF-0 for the first VF. VFs are numbered starting * from 0. The value associated with this key follows the "device node" * format. The parameters in this node specify configuration that applies * to the VF specified in the key. Leading zeros are not permitted in VF * index. Configuration for the second VF must be specified in a node with * the key VF-1. VF-01 is not a valid key. * * DEVICE NODES * 1) All keys specified in this section are mandatory. * 2) The device node must contain a key with the name DRIVER_CONFIG_NAME. The * value associated with this key is an nvlist following the subsystem node * format. The parameters in this key specify configuration that is specific * to a particular device driver. * 3) The device node must contain a key with the name IOV_CONFIG_NAME. The * value associated with this key is an nvlist following the subsystem node * format. The parameters in this key specify configuration that is consumed * by the SR-IOV infrastructure. * * SUBSYSTEM NODES * 1) A subsystem node specifies configuration parameters that apply to a * particular subsystem (driver or infrastructure) of a particular device * (PF or individual VF). * Note: We will refer to the section of the configuration schema that * specifies the parameters for this subsystem and device * configuration as the device/subystem schema. * 2) The subsystem node must contain only keys that correspond to parameters * that are specified in the device/subsystem schema. * 3) Every parameter specified as required in the device/subsystem schema is * a mandatory key in the subsystem node. * Note: All parameters that are not required in device/subsystem schema are * optional keys. In particular, any parameter specified to have a * default value in the device/subsystem schema is optional. The * kernel is responsible for applying default values. * 4) The value of every parameter in the device node must conform to the * restrictions of the type specified for that parameter in the device/ * subsystem schema. * * The following is an example of a valid configuration, when validated against * the schema example given above. * * PF (NVLIST): * driver (NVLIST): * iov (NVLIST): * num_vfs (NUMBER): 3 (3) (0x3) * device (STRING): [ix0] * VF-0 (NVLIST): * driver (NVLIST): * vlan (NUMBER): 1000 (1000) (0x3e8) * iov (NVLIST): * passthrough (BOOL): TRUE * VF-1 (NVLIST): * driver (NVLIST): * iov (NVLIST): * VF-2 (NVLIST): * driver (NVLIST): * mac-addr (BINARY): 6 020102030405 * iov (NVLIST): */ struct pci_iov_arg { void *config; size_t len; }; #define IOV_CONFIG _IOW('p', 10, struct pci_iov_arg) #define IOV_DELETE _IO('p', 11) #define IOV_GET_SCHEMA _IOWR('p', 12, struct pci_iov_schema) #endif - Index: head/sys/sys/ipmi.h =================================================================== --- head/sys/sys/ipmi.h (revision 365222) +++ head/sys/sys/ipmi.h (revision 365223) @@ -1,181 +1,180 @@ /*- * SPDX-License-Identifier: BSD-2-Clause-FreeBSD * * Copyright (c) 2006 IronPort Systems Inc. * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

The elements * are singly linked for minimum space and pointer manipulation overhead at * the expense of O(n) removal for arbitrary elements. New elements can be * added to the list after an existing element or at the head of the list. * Elements being removed from the head of the list should use the explicit * macro for this purpose for optimum efficiency. A singly-linked list may * only be traversed in the forward direction. Singly-linked lists are ideal * for applications with large datasets and few or no removals or for * implementing a LIFO queue. * * A singly-linked tail queue is headed by a pair of pointers, one to the * head of the list and the other to the tail of the list. The elements are * singly linked for minimum space and pointer manipulation overhead at the * expense of O(n) removal for arbitrary elements. New elements can be added * to the list after an existing element, at the head of the list, or at the * end of the list. Elements being removed from the head of the tail queue * should use the explicit macro for this purpose for optimum efficiency. * A singly-linked tail queue may only be traversed in the forward direction. * Singly-linked tail queues are ideal for applications with large datasets * and few or no removals or for implementing a FIFO queue. * * A list is headed by a single forward pointer (or an array of forward * pointers for a hash table header).
