✨ xe_configfs...tore_post_bb(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one is not the full xe_configfs_get_ctx_restore_post_bb(9) name spelled out, the title got cutely truncated, but that's literally what we're talking about, and it's giving "getter function for the configfs ctx_restore_post_bb" energy 💅

---

🎀 NAME 🎀

xe_configfs_get_ctx_restore_post_bb — get the configfs ctx_restore_post_bb setting. that's it. that's her whole personality. 🦋

---

🌸 SYNOPSIS 🌸

u32 xe_configfs_get_ctx_restore_post_bb (struct pci_dev *pdev , enum
xe_engine_class class , const u32 **cs );

yes queen, it returns a u32, and yes, the line break in the original is exactly like that — we do not fix, we do not merge, we do not pass go 🫶

---

⭐ ARGUMENTS ⭐

• pdev — the pci device. lowkey the main character of the whole call ngl 💖
• class — hw engine class. as in, which hardware engine we're talking about. the vibe check for where the answer applies 🎀
• cs — pointer to the bb to use — only valid during probe. 📌 okay so this one matters: it's valid during probe only, so no holding onto it and using it later, iykyk 🙈

---
