eeh_pe_state_mark(9)

📦 version 7.3.1, in nixpkgs unstable

💅 eeh_pe_state_mark(9) — from the Kernel API Manual, bestie ✨

okay so welcome to the group chat, this is eeh_pe_state_mark from the Kernel API Manual and honestly? she's a tiny function with main character energy 🎀

✨ NAME ✨

eeh_pe_state_mark — marks the specified state for a PE and its associated device 🫶

🌸 SYNOPSIS 🌸

void eeh_pe_state_mark (struct eeh_pe *root , int state );

like literally that's the whole signature, no cap 💅

🦋 ARGUMENTS 🦋

okay bestie don't come for me but the docs are kinda ghosting us here:

  • root — -- undescribed -- 😭 yeah. that's genuinely it. the manpage said nothing. it's giving mystery.
  • state — -- undescribed -- 🙈 same vibe. no description. we simply do not know from this page alone. (iykyk — go read the source if you need the tea.)
ngl I'm not gonna invent details for these two, because making stuff up about kernel args is not the move 💀 the original page literally leaves them blank, so blank they stay.

🔥 DESCRIPTION 🔥

so here's the situation: an EEH error affects the current PE and its child PEs. (yes, the whole little family, it's a whole thing 😭)

this function is the one that goes around marking the appropriate state for the affected PEs and the associated devices. that's her job. that's her whole thing. iconic behaviour honestly 👑

she takes root and state, and the affected PEs plus their associated devices get marked. periodt.

🧚 SEE ALSO 🧚

she runs with a whole crew, and the source file lives in the kernel at ./arch/powerpc/kernel/eeh_pe.c — go say hi to the rest of the squad:

like, twenty-two friends and a source path. she's connected 💖

and that's the whole page, bestie — no crumbs left behind, every flag and reference accounted for ✨

this little love letter came to you from ./arch/powerpc/kernel, dated October 2026, and it's signed eeh_pe_state_mark(9) 🎀 mwah, go mark some state 💜
