dpsw_enable(9)

💖 dpsw_enable(9) — from the Kernel API Manual, bestie 💖

okay so picture this: it's a manpage, it's section 9, it's called dpsw_enable, and it lives in the Kernel API Manual. that's the vibe. and honestly? it's giving "one job, does it well" energy. 🎀

---

✨ NAME ✨

dpsw_enable — Enable DPSW functionality

like literally just turn the DPSW on. that's the whole assignment. slay. 💅

---

🦋 SYNOPSIS 🦋

int dpsw_enable (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token );

three args, one int coming back at you. no cap, that's it. 🫶

---

🌸 ARGUMENTS 🌸

• mc_io — Pointer to MC portal's I/O object. yeah, the whole portal deal — you're not talking to DPSW directly, you're going through MC's I/O object. iykyk.
• cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. so like, pick your flags from that family, okay? ⭐
• token — Token of DPSW object. it's the lil' handle that says which DPSW you mean. don't lose it fr fr.

---

💀 RETURN 💀

Completion status. '0' on Success; Error code otherwise.

so 0 = we ate and left no crumbs 🔥. anything else = an error code, and you should probably look at it instead of pretending you didn't see it 😭.

ngl, always actually check the return value. 0 is the happy path, everything else is the signal to go debug.
