STRUCT SDW_PORT_RUNTIME(9)

💖 NAME 💖

struct sdw_port_runtime — Runtime port parameters for Master or Slave. This is the Kernel API Manual page for it, bestie, so pull up a chair and let’s get into the port-runtime lore. 🫶

✨ SYNOPSIS ✨

Here’s the struct, literally character-for-character, no cap:

       struct sdw_port_runtime {
           int num;
           int ch_mask;
           struct sdw_transport_params transport_params;
           struct sdw_port_params port_params;
           struct list_head port_node;
           unsigned int lane;
        };

🎀 Members 🎀

• num — Port number. For audio streams, valid port number ranges from [1,14]. 👑
• ch_mask — Channel mask. Slay, channels.
• transport_params — Transport parameters. The transport-param vibes are immaculate.
• port_params — Port parameters. Yes, another params field, keep up bestie.
• port_node — List node for Master or Slave port_list. It’s the lil list connector.
• lane — Which lane is used. Lane check: iconic.

🦋 Description 🦋

Okay so here’s the tea: the SoundWire spec has no mention of ports for Master interface, but the concept is logically extended. That’s the whole note — the idea gets extended anyway, iykyk. 💅
