They may also export a set of 36 * topology node specific methods that can be invoked directly via 37 * topo_method_invoke() or indirectly via the 38 * topo_prop_get* family of functions to access dynamic property data. 39 * 40 * Module Plugin API 41 * 42 * Enumerators must provide entry points for initialization and clean-up 43 * (_topo_init() and _topo_fini()). In their _topo_init() function, an 44 * enumerator should register (topo_mod_register()) its enumeration callback 45 * and allocate resources required for a subsequent call to the callback. 46 * Optionally, methods may also be registered with topo_method_register(). 47 * 48 * In its enumeration callback routine, the module should search for resources 49 * within its realm of responsibility and create any node ranges, 50 * topo_node_range_create() and nodes, topo_node_bind(). The Enumerator 51 * module is handed a node to which it may begin attaching additional 52 * topology nodes. The enumerator may only access those nodes within its 53 * current scope of operation: the node passed into its enumeration op and 54 * any nodes it creates during enumeration. If the enumerator requires walker- 55 * style access to these nodes, it must use 56 * topo_mod_walk_init()/topo_walk_step()/topo_walk_fini(). 57 * 58 * If additional helper modules need to be loaded to complete the enumeration 59 * the module may do so by calling topo_mod_load(). Enumeration may then 60 * continue with the module handing off enumeration to its helper module 61 * by calling topo_mod_enumerate(). Similarly, a module may call 62 * topo_mod_enummap() to kick-off enumeration according to a given XML 63 * topology map file. A module *may* not cause re-entrance to itself 64 * via either of these interfaces. If re-entry is detected an error 65 * will be returned (ETOPO_ENUM_RECURS). 66 * 67 * If the module registers a release callback, it will be called on a node 68 * by node basis during topo_snap_rele(). Any private node data may be 69 * deallocated or methods unregistered at that time. Global module data 70 * should be cleaned up before or at the time that the module _topo_fini 71 * entry point is called. 72 * 73 * Module entry points and method invocations are guaranteed to be 74 * single-threaded for a given snapshot handle. Applications may have 75 * more than one topology snapshot open at a time. This means that the 76 * module operations and methods may be called for different module handles 77 * (topo_mod_t) asynchronously. The enumerator should not use static or 78 * global data structures that may become inconsistent in this situation. 79 * Method operations may be re-entrant if the module invokes one of its own 80 * methods directly or via dynamic property access. Caution should be 81 * exercised with method operations to insure that data remains consistent 82 * within the module and that deadlocks can not occur. 83 */ 84 85 #include <pthread.h> 86 #include <assert.h> 87 #include <errno.h> 88 #include <dirent.h> 89 #include <limits.h> 90 #include <alloca.h> 91 #include <unistd.h> 92 #include <stdio.h> 93 #include <ctype.h> 94 #include <sys/param.h> 95 #include <sys/utsname.h> 96 #include <sys/smbios.h> 97 #include <sys/fm/protocol.h> 98 99 #include <topo_alloc.h> 100 #include <topo_error.h> 101 #include <topo_file.h> 102 #include <topo_fmri.h> 103 #include <topo_module.h> 104 #include <topo_method.h> 105 #include <topo_string.h> 106 #include <topo_subr.h> 107 #include <topo_tree.h> 108 109 #define PLUGIN_PATH "plugins" 110 #define PLUGIN_PATH_LEN MAXNAMELEN + 5 111 112 topo_mod_t * 113 topo_mod_load(topo_mod_t *pmod, const char *name, 114 topo_version_t version) 115 { 116 char *path;
