ghes_map_error_status(9)

🌸 ghes_map_error_status(9) 🌸

okay bestie, so this one's from the Kernel API Manual, section 9 — yes, that section 9, the kernel-internals one, we're literally in the big leagues now 💅

---

✨ NAME ✨

ghes_map_error_status — the girlies that take your error status address and turn it into a virtual address, no cap 💖

---

🎀 SYNOPSIS 🎀

int ghes_map_error_status (struct ghes *ghes );

---

🦋 ARGUMENTS 🦋

• ghes — a pointer to the GHES structure 🫶 lowkey your entry ticket, like the VIP wristband for this whole function

---

🌸 DESCRIPTION 🌸

so here's the vibe: this function reads the error status address out of the ACPI HEST table and maps it to a virtual address that the kernel can actually access ✨

it's giving "translating between two worlds" tbh. the address is just sitting there in the HEST table, and this function is the main character that gets it into a form the kernel can touch 😭👑

---

🔥 RETURN 🔥

• 0 on success 🎉 slay, we mapped it
• error code on failure 💀 not every story has a happy ending bestie

---

💜 SEE ALSO 💜

• Kernel file ./drivers/acpi/apei/ghes.c
• ghes_estatus_pool_region_free(9)
• struct ghes_task_work(9)
• ghes_has_active_errors(9)
• ghes_unmap_error_status(9)

like, definitely go read ghes_unmap_error_status(9) after this one — you can't just map and dip, that's not the vibe 🙈 (also ghes_has_active_errors(9) is right there if you're nosy about whether anything's actually wrong 👀)

---

ngl bestie, a tiny heads up from the page itself: this is kernel-internals territory in ./drivers/acpi/apei — so keep those error codes checked, fr fr 🍓

---

and that's the whole page, no crumbs left 🧚‍♀️💫 source/version: ./drivers/acpi/apei, dated October 2026 — go forth and map those error statuses, icon ✨👑
