STRUCT HL_INFO_CLK_THROTTLE(9)

🌸 NAME 🌸

struct hl_info_clk_throttle — clock throttling reason 💅✨ and yes bestie, this is the struct hl_info_clk_throttle(9) page from the Kernel API Manual, so buckle up 🫶

✨ SYNOPSIS ✨

Okay so here's the whole struct, no cap — copy it exactly if you're typing it out, because we do not freehand kernel structs in this group chat 😭💀

       struct hl_info_clk_throttle {
           __u32 clk_throttling_reason;
           __u32 pad;
           __u64 clk_throttling_timestamp_us[HL_CLK_THROTTLE_TYPE_MAX];
           __u64 clk_throttling_duration_ns[HL_CLK_THROTTLE_TYPE_MAX];
        };

And yeah, there's a pad field in there too — the Members list on this page doesn't give it its own little paragraph, so I'm not gonna invent lore for it 🙈 it's just present in the struct, periodt.

💫 Members 💫

• clk_throttling_reason — each bit represents a clk throttling reason 👑 so like, bit-by-bit, that's the reason map, iykyk.
• clk_throttling_timestamp_us — represents CPU timestamp in microseconds of the start-event 🕐 this one's a __u64 array sized HL_CLK_THROTTLE_TYPE_MAX in the struct, and it's giving timestamp energy for the start-event, fr fr.
• clk_throttling_duration_ns — the clock throttle time in nanosec 💅 yes, nanosec exactly as written — that's the duration field, and it's also a __u64 array sized HL_CLK_THROTTLE_TYPE_MAX 🌸

tiny note bestie: the struct also has __u32 pad; in the synopsis, but this page doesn't give it a separate member description, so we're just acknowledging it and moving on 🫶
