drm_ras_nl_...unter_dumpit(9)

💅 NAME 💅

Okay bestie, gather round — this page is literally the Kernel API Manual entry for drm_ras_nl_get_error_counter_dumpit, and its whole job is: dump all Error Counters ✨ (yes, the header on this page is genuinely truncated mid-word — drm_ras_nl_...unter_dumpit(9) — and we're just gonna vibe with that, no cap 😭)

---

🎀 SYNOPSIS 🎀

int drm_ras_nl_get_error_counter_dumpit (struct sk_buff *skb , struct
       netlink_callback *cb );

---

🌸 ARGUMENTS 🌸

• skb — the Netlink message buffer, aka the little envelope everything gets stuffed into 💌
• cb — the callback context, and specifically the thing that makes multi-part dumps possible 🫶

---

✨ DESCRIPTION ✨

So here's the tea: this function walks over all the error counters in a given Node and appends each one's attributes — that's the ID, the name, and the value — onto the netlink message buffer you handed it. Every single one, no skipping, we're thorough like that 💅

It keeps its place using cb->ctx to track progress, which matters big time in case the message buffer fills up — that's how the whole multi-part dump situation works 👑

And on buffer overflow? It updates the context so the next invocation picks right back up from the last node. Resume-from-where-we-left-off energy, lowkey iconic 🌈

---

🔥 RETURN 🔥

• 0 — if all the errors fit in skb, we're done, slay, go home 🎉
• the number of bytes added to skb — if the buffer filled up, which means you do need a multi-part continuation (it's giving "to be continued…" 🦋)
• a negative error code — if something went wrong 😭

Okay that's the whole page, bestie — it lives over in ./drivers/gpu/drm and this version is dated October 2026. Mwah, mwah, go dump some counters, periodt 💅✨🎀
