panthor_fw_glb_wait_acks(9)

💖 panthor_fw_glb_wait_acks(9) 💖

okay so bestie, welcome to section 9 of the Kernel API Manual — this one's about panthor_fw_glb_wait_acks, and honestly it does exactly what it says on the tin. It waits. For global requests. To be acknowledged. Iconic behavior, no notes. 👑

---

✨ NAME ✨

panthor_fw_glb_wait_acks — wait for global requests to be acknowledged, periodt.

---

🎀 SYNOPSIS 🎀

int panthor_fw_glb_wait_acks (struct panthor_device *ptdev , u32
req_mask , u32 *acked , u32 timeout_ms );

like… four args, one int back. cute and efficient. 💅

---

🌸 ARGUMENTS 🌸

• ptdev — the Device. your main character struct, the whole reason we're here. 🫶
• req_mask — Mask of requests to wait for. basically your wishlist of acks, in bitmask form. ✨
• acked — Pointer to field that's updated with the acked requests. and listen — if the function returns 0, then *acked == req_mask. like, the whole mask. all of it. that's the vibe check passing. 🔥
• timeout_ms — Timeout expressed in milliseconds. yes, milliseconds. not seconds, not vibes. don't come for me. ⏰

---

⭐ RETURN ⭐

• 0 on success 😌✨
• -ETIMEDOUT otherwise 😭💀

that's it. that's the whole return section. she's brief but she's honest.
