amdgpu_dpm_get_xcp_metrics(9)

💅 amdgpu_dpm_get_xcp_metrics — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual entry for amdgpu_dpm_get_xcp_metrics(9). yes we're reading kernel docs together, this is our bonding time, don't fight it 🎀

---

✨ NAME ✨

amdgpu_dpm_get_xcp_metrics — gets you the metrics for one specific compute partition, no cap 💫

---

🦋 SYNOPSIS 🦋

ssize_t amdgpu_dpm_get_xcp_metrics (struct amdgpu_device *adev , int xcp_id , void *table );

look at her. three args. absolutely iconic signature, she ate 🔥

---

🌸 ARGUMENTS 🌸

• adev — pointer to the device. like, the whole GPU situation, you hand her the device and she knows what to do 💖
• xcp_id — the identifier of the XCP you want metrics for. which compute partition, basically. you gotta tell her which one, she's not a mind reader 🙈
• table — pointer to a buffer where the metrics get stored. and this is the main character detail — if it's NULL, the function just returns the size of the metrics structure instead of filling anything in. so you can ask "how much room do i need?" before you commit. love that for us ✨

---

👑 DESCRIPTION 👑

so what does she actually do? she retrieves metrics for a specific XCP — and we're talking the good stuff: details like VCN/JPEG activity, clock frequencies, and other performance metrics 🎀

and again, because it matters: if the table parameter is NULL, the function returns the size of the metrics structure without populating it. size only, no data, just a little vibe check on how big your buffer needs to be 💅

---

⭐ RETURN ⭐

• size of the metrics structure on success 🌈
• a negative error code on failure 😭 (yes, negative. that's your red flag, bestie, pay attention)

siblings! go say hi 👋

• Kernel file ./drivers/gpu/drm/amd/pm/amdgpu_dpm.c

• amdgpu_dpm_get_temp_metrics(9)
• amdgpu_dpm_is_temp_metrics_supported(9)

fr fr though — always check that negative return. a negative error code is not a size, it's a cry for help 💀

and that's the page, bestie 🫶 this whole thing lives in ./drivers/gpu/drm/amd/pm, it's part of the Kernel API Manual, and it's dated October 2026 — so like, future-coded of us. mwah 💋✨
