EEH_POSSIBLE_ERROR(9)

💅 EEH_POSSIBLE_ERROR(9) 🫶

okay so welcome to the EEH_POSSIBLE_ERROR(9) page, straight out of the Kernel API Manual — yes bestie, we're in kernel land today and it's honestly iconic ✨

---

🌸 NAME 🌸

EEH_POSSIBLE_ERROR — test for possible MMIO failure.

like, that's the whole vibe. it checks if something might have gone wrong with MMIO. no cap 💅

---

🦋 SYNOPSIS 🦋

EEH_POSSIBLE_ERROR (val , type );

that's it. two args, look at her go 🎀

---

✨ ARGUMENTS ✨

• val — -- undescribed -- 😭 the docs literally have nothing for this one. not me being handed a mystery box. it's giving "figure it out yourself, bestie" 🙈
• type — -- undescribed -- 💀 same energy. absolutely no description provided. the manpage said "no thoughts, head empty" and honestly? relatable.

fr fr, both of these are marked -- undescribed -- in the source. i'm not hiding anything from you, that's just what it says 👑

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — if this macro yields TRUE, then the caller relays to eeh_check_failure, which goes and does further tests out of line. like it steps aside to do the extra detective work 🔍✨

so the macro is basically the vibe check, and eeh_check_failure is the full investigation. main character energy all around 👑
