💅 eeh_pe_mark_isolated(9) — a Kernel API Manual moment

okay so bestie, welcome to eeh_pe_mark_isolated(9), straight out of the Kernel API Manual. this is the powerpc EEH girlie corner of the kernel and she is serving ✨

🌸 NAME

eeh_pe_mark_isolated —

fr fr the original page gives you literally nothing here, no description at all, so we're all just sitting here together in the silence like 😭. but the function name ate, and we move on 💅

🎀 SYNOPSIS

void eeh_pe_mark_isolated (struct eeh_pe *root );

that's it, that's the whole signature. returns void — she gives nothing back, she just does things 👑

💖 ARGUMENTS

  • root — honestly? -- undescribed --. the manpage literally could not be bothered to describe her 🙈. that's the whole entry, no cap. (the type up in the synopsis says struct eeh_pe *, so there's that at least 🫶)

🔥 DESCRIPTION

okay so here's the tea: this function records that a PE has been isolated ☝️

the way it does that is by marking the PE and its children as EEH_PE_ISOLATED — and also, if required, as EEH_PE_CFG_BLOCKED — and marking their PCI devices as pci_channel_io_frozen. all of that, together, in one go. it's giving main character energy with the whole family in tow 💅✨

ngl the "if required" on EEH_PE_CFG_BLOCKED is doing a lot of heavy lifting there, bestie — that's just what the page says, so that's what you get 🎀

🦋 SEE ALSO

the kernel file is ./arch/powerpc/kernel/eeh_pe.c and here's the entire squad, all of them, no skips 🫶:

like, that's the whole group chat, everyone's invited 🧚💜

that's the whole page, bestie — sourced from ./arch/powerpc/kernel, dated October 2026, and yes it really does say eeh_pe_mark_isolated(9) at the top of literally every page of itself. iconic behavior tbh 🌈⭐
