rio_route_get_entry(9)

🦋 rio_route_get_entry(9) 🦋

okay so welcome to the Kernel API Manual page for rio_route_get_entry, bestie — this is the little function that reads one entry out of a switch routing table, and it's honestly giving useful-core energy 💅

✨ NAME ✨

rio_route_get_entry — read an entry from a switch routing table. that's it, that's the name, no cap 🎀

🌸 SYNOPSIS 🌸

int rio_route_get_entry (struct rio_dev *rdev , u16 table , u16
       route_destid , u8 *route_port , int lock );

💖 ARGUMENTS 💖

• rdev — the RIO device, obvi 🦋
• table — the routing table ID
• route_destid — the destination ID to be routed
• route_port — pointer to read the port number into
• lock — apply a hardware lock on switch device flag (1=lock, 0=no_lock)

👑 DESCRIPTION 👑

so here's the tea: if it's available, this calls the switch specific get_entry method to fetch a route entry from a switch routing table. otherwise it uses the standard RT read method as defined by the RapidIO specification 🔥

a specific routing table can be selected using the table argument if a switch has per port routing tables, or the standard (or global) table may be used by passing RIO_GLOBAL_TABLE in table ✨

returns 0 on success or -EINVAL on failure. periodt 💅
