It's strongly desirable to cache 53fcf3ce44SJohn Forte * allocate the entire packet in one common place. So we define a set a 547ff83669SZhong Wang * of rules. In a contiguous block of memory, the top portion of the 557ff83669SZhong Wang * block points to ulp packet private area, next follows the fc_packet 56fcf3ce44SJohn Forte * structure used extensively by all the consumers and what follows this 577ff83669SZhong Wang * is the FCA packet private. Note that given a packet structure, it is 587ff83669SZhong Wang * possible to get to the ULP and FCA Packet private fields using 59fcf3ce44SJohn Forte * ulp_private and fca_private fields (which hold pointers) respectively. 60fcf3ce44SJohn Forte * 61fcf3ce44SJohn Forte * It should be noted with a grain of salt that ULP Packet private size 62fcf3ce44SJohn Forte * varies between two different ULP types, So this poses a challenge to 637ff83669SZhong Wang * compute the correct size of the whole block on a per port basis. The 64fcf3ce44SJohn Forte * transport layer doesn't have a problem in dealing with FCA packet 65fcf3ce44SJohn Forte * private sizes as it is the sole manager of ports underneath. Since 66fcf3ce44SJohn Forte * it's not a good idea to cache allocate different sizes of memory for 67fcf3ce44SJohn Forte * different ULPs and have the ability to choose from one of these caches 68fcf3ce44SJohn Forte * based on ULP type during every packet allocation, the transport some 697ff83669SZhong Wang * what wisely (?) hands off this job of cache allocation to the ULPs 70fcf3ce44SJohn Forte * themselves. 71fcf3ce44SJohn Forte * 72fcf3ce44SJohn Forte * That means FCAs need to make their packet private size known to the 737ff83669SZhong Wang * transport to pass it up to the ULPs. This is done during 74fcf3ce44SJohn Forte * fc_fca_attach(). And the transport passes this size up to ULPs during 75fcf3ce44SJohn Forte * fc_ulp_port_attach() of each ULP. 76fcf3ce44SJohn Forte * 777ff83669SZhong Wang * This leaves us with another possible question; How are packets 787ff83669SZhong Wang * allocated for ELS's started by the transport itself ? Well, the port 797ff83669SZhong Wang * driver during attach time, cache allocates on a per port basis to 80fcf3ce44SJohn Forte * handle ELSs too. 81fcf3ce44SJohn Forte */ 82fcf3ce44SJohn Forte 83fcf3ce44SJohn Forte #include <sys/note.h> 84fcf3ce44SJohn Forte #include <sys/types.h> 85fcf3ce44SJohn Forte #include <sys/varargs.h> 86fcf3ce44SJohn Forte #include <sys/param.h> 87fcf3ce44SJohn Forte #include <sys/errno.h> 88fcf3ce44SJohn Forte #include <sys/uio.h> 89fcf3ce44SJohn Forte #include <sys/buf.h> 90fcf3ce44SJohn Forte #include <sys/modctl.h> 91fcf3ce44SJohn Forte #include <sys/open.h> 92fcf3ce44SJohn Forte #include <sys/kmem.h> 93fcf3ce44SJohn Forte #include <sys/poll.h> 94fcf3ce44SJohn Forte #include <sys/conf.h> 95fcf3ce44SJohn Forte #include <sys/cmn_err.h> 96fcf3ce44SJohn Forte #include <sys/stat.h> 97fcf3ce44SJohn Forte #include <sys/ddi.h> 98fcf3ce44SJohn Forte #include <sys/sunddi.h> 99fcf3ce44SJohn Forte #include <sys/promif.h> 100fcf3ce44SJohn Forte #include <sys/byteorder.h> 101fcf3ce44SJohn Forte #include <sys/fibre-channel/fc.h> 102fcf3ce44SJohn Forte #include <sys/fibre-channel/impl/fc_ulpif.h> 103fcf3ce44SJohn Forte #include <sys/fibre-channel/impl/fc_fcaif.h> 104fcf3ce44SJohn Forte #include <sys/fibre-channel/impl/fctl_private.h> 105fcf3ce44SJohn Forte #include <sys/fibre-channel/impl/fc_portif.h> 106fcf3ce44SJohn Forte 107fcf3ce44SJohn Forte /* These are referenced by fp.c! */ 108fcf3ce44SJohn Forte int did_table_size = D_ID_HASH_TABLE_SIZE; 109fcf3ce44SJohn Forte int pwwn_table_size = PWWN_HASH_TABLE_SIZE; 110fcf3ce44SJohn Forte 1117ff83669SZhong Wang static fc_ulp_module_t *fctl_ulp_modules; 1127ff83669SZhong Wang static fc_fca_port_t *fctl_fca_portlist; 113fcf3ce44SJohn Forte static fc_ulp_list_t *fctl_ulp_list; 114fcf3ce44SJohn Forte 115fcf3ce44SJohn Forte static char fctl_greeting[] = 116fcf3ce44SJohn Forte "fctl: %s ULP same type (0x%x) as existing module.\n"; 117fcf3ce44SJohn Forte 118fcf3ce44SJohn Forte static char *fctl_undefined = "Undefined"; 119fcf3ce44SJohn Forte 120fcf3ce44SJohn Forte /* 121fcf3ce44SJohn Forte * This lock protects the fc_ulp_module_t linked list (i.e. mod_next field) 122fcf3ce44SJohn Forte */ 123fcf3ce44SJohn Forte 124fcf3ce44SJohn Forte static krwlock_t fctl_ulp_lock; 125fcf3ce44SJohn Forte 126fcf3ce44SJohn Forte /* 127fcf3ce44SJohn Forte * The fctl_mod_ports_lock protects the mod_ports element in the 128fcf3ce44SJohn Forte * fc_ulp_ports_t structure 129fcf3ce44SJohn Forte */ 130fcf3ce44SJohn Forte 131fcf3ce44SJohn Forte static krwlock_t fctl_mod_ports_lock; 132fcf3ce44SJohn Forte 133fcf3ce44SJohn Forte /* 134fcf3ce44SJohn Forte * fctl_port_lock protects the linked list of local port structures 1357ff83669SZhong Wang * (fctl_fca_portlist).
