STRUCT DWC_PCIE_RASDES_INFO(9)

💅 struct dwc_pcie_rasdes_info(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for struct dwc_pcie_rasdes_info — yes the whole page is named after it, it's giving main character energy and honestly? deserved. 🎀

---

✨ NAME ✨

struct dwc_pcie_rasdes_info — literally just stores controller common information. that's it. that's the whole job. 🫶

---

🌸 SYNOPSIS 🌸

struct dwc_pcie_rasdes_info {
    u32 ras_cap_offset;
    struct mutex reg_event_lock;
 };

look at her. two members. clean. minimal. iconic. 👑

---

🦋 Members 🦋

• ras_cap_offset — the RAS DES vendor specific extended capability offset. it's a u32, it holds that offset, that's the vibe. ✨
• reg_event_lock — a struct mutex that's used for the RAS DES shadow event registers. she locks. she protects. she does not elaborate. 💅

---

💜 Description 💜

so the whole point: any parameter that's constant across, like, all the files in the debugfs hierarchy for a single controller gets stored in this struct. every single one. it's the shared-lore struct, iykyk. 🧚

and when does she show up? during initialization — she's allocated and then assigned to the controller specific struct dw_pcie. so like, she doesn't just exist for fun, she gets handed off and becomes part of the controller's whole situation. no cap. 🔥

ngl this one is short but she's important — the debugfs crew all share her, so bestie, treat her right. 🍓
