STRUCT SCMI_SHMEM_IO_OPS(9)

💖 struct scmi_shmem_io_ops(9) 💖

okay so bestie, welcome to the struct scmi_shmem_io_ops page — it's straight out of the Kernel API Manual, section 9, and it's literally the glow-up guide for talking to Shared Memory. no cap, this is the whole vibe: it's the little struct that holds the I/O operations you use to read from and write to Shared Memory. slay. 💅

✨ NAME ✨

struct scmi_shmem_io_ops — the I/O operations that let you read from / write to Shared Memory. that's it, that's the whole assignment 🎀

🦋 SYNOPSIS 🦋

here's the shape of it, bestie — copy it exactly, don't freestyle:

struct scmi_shmem_io_ops {
    shmem_copy_fromio_t fromio;
    shmem_copy_toio_t toio;
 };

two members, two moods, both iconic 👑
