STRUCT HOST1X_CLIENT_OPS(9)

💅 struct host1x_client_ops(9)

okay so bestie, welcome to the man page for struct host1x_client_ops — that's the host1x client operations struct, and it lives in the Kernel API Manual. don't worry, it's not scary, it's actually kind of iconic 🎀

---

✨ NAME ✨

struct host1x_client_ops — host1x client operations 🦋

---

🌸 SYNOPSIS 🌸

here's the whole struct, exactly as it is, no cap:

struct host1x_client_ops {
    int (*early_init)(struct host1x_client *client);
    int (*init)(struct host1x_client *client);
    int (*exit)(struct host1x_client *client);
    int (*late_exit)(struct host1x_client *client);
    int (*suspend)(struct host1x_client *client);
    int (*resume)(struct host1x_client *client);
 };

like… look at all those function pointers. it's giving lifecycle from start to finish, honestly 👑

🫶 Members 🫶

so each of these is a pointer to a function that takes a struct host1x_client *client, and here's what each one is for:

• early_init — the host1x client early initialization code ✨ like the very first thing that happens, the pre-game if you will
• init — the host1x client initialization code 🌱 the main setup moment
• exit — the host1x client tear down code 🧹 cleanup time bestie
• late_exit — the host1x client late tear down code 🦋 the final cleanup, saving the last bits for last
• suspend — the host1x client suspend code 💤 nap mode
• resume — the host1x client resume code ⭐ wakey wakey, back at it

ngl the symmetry here is so satisfying — early_init … late_exit, suspend … resume. the way that struct is organized. obsessed 😭💖
