STRUCT IOSM_DEVLINK_SIO(9)

💅 NAME 💅

okay bestie, welcome to the struct iosm_devlink_sio(9) page in the Kernel API Manual. This struct is literally the SIO instance — that’s the whole name, and yes, we’re keeping it cute and exact. 🫶

✨ SYNOPSIS ✨

okay so here’s the struct, copied exactly, no cap, no edits, periodt:

       struct iosm_devlink_sio {
           struct sk_buff_head rx_list;
           struct completion read_sem;
           int channel_id;
           struct ipc_mem_channel *channel;
           u32 devlink_read_pend;
        };

• rx_list — Downlink skbuf list received from CP. Literally the downlink skbuf list that came in from CP, bestie. 💅
• read_sem — Needed for the blocking read or downlink transfer. This one’s the semaphore moment for the blocking read or the downlink transfer. 🔥
• channel_id — Reserved channel id for flashing/CD collection to RAM. It’s the reserved channel id for flashing and CD collection to RAM. 👑
• channel — Channel instance for flashing and coredump. The channel instance for flashing and coredump, iconic behavior only. ✨
• devlink_read_pend — Check if read is pending. This is the vibe check for whether a read is pending. 👀
