amdgpu_ras_q..._error_count(9)

💖 amdgpu_ras_query_error_count — the Kernel API Manual tea 💖

okay so bestie, welcome to amdgpu_ras_query_error_count(9) from the Kernel API Manual — yes that's the whole vibe, sit down, grab a boba, we're learning about GPU error counters 🧚✨

---

✨ NAME ✨

amdgpu_ras_query_error_count — literally just "Get error counts of all IPs or specific IP" 🎀 that's the entire assignment and she ate

---

🌸 SYNOPSIS 🌸

int amdgpu_ras_query_error_count (struct amdgpu_device *adev , unsigned
long *ce_count , unsigned long *ue_count , struct ras_query_if
*query_info );

like, one function, four args, no cap 💅

---

🦋 ARGUMENTS 🦋

• adev — pointer to AMD GPU device 🫶 the actual card we're snooping on, main character energy fr
• ce_count — pointer to an integer to be set to the count of correctible errors. cute little oopsies that got fixed, we love a recovery arc 💖
• ue_count — pointer to an integer to be set to the count of uncorrectible errors 😭 not so cute, these ones didn't get fixed
• query_info — pointer to ras_query_if if the query request is only for a specific ip block; if info is NULL, then the query request is for all the ip blocks that support query ras error counters/status 🌈 iykyk — pass NULL and you're asking everyone at once

---

⭐ DESCRIPTION ⭐

So the way this works: if set, ce_count or ue_count count and return the corresponding error counts in those integer pointers 🔥 like they'll get filled in with the numbers, that's the whole point.

Return 0 if the device supports RAS 👑 and return -EOPNOTSUPP if the device doesn't support RAS 💀 that's the vibe check — no RAS support, no counts, sorry bestie.

ngl, this is the part where you check your return value. 0 = slay, -EOPNOTSUPP = the hardware said "not me" 🙈
