STRUCT TI_SCI_MSG_RESP_QUERY_CLOCK_FREQ(9)

💖 struct ti_sci_msg_resp_query_clock_freq(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this little section is all about struct ti_sci_msg_resp_query_clock_freq, and it's literally the response you get back when you ask the TI SCI firmware "hey what's this clock running at?" 🕐💅

---

🌸 NAME 🌸

struct ti_sci_msg_resp_query_clock_freq — the response to a clock frequency query, periodt 🎀

---

🦋 SYNOPSIS 🦋

struct ti_sci_msg_resp_query_clock_freq {
    struct ti_sci_msg_hdr hdr;
    u64 freq_hz;
 };

like, that's the whole shape of it, no cap ✨

---

👑 Members 👑

• hdr — the generic header, aka the vibe check every TI SCI message starts with 🫶
• freq_hz — the frequency that is the best match, in Hz. bestie, best match — the firmware picks the closest one it's got 🔥

---

💜 Description 💜

This struct is the response to request type TI_SCI_MSG_QUERY_CLOCK_FREQ 💫

⚠️ NOTE: if the request cannot be satisfied, the message will be of type NACK. like, it's not gonna ghost you with a fake frequency — it straight-up NACKs. respect 🙈
