STRUCT XE_DEVCOREDUMP(9)

✨ struct xe_devcoredump — the Kernel API Manual tea ☕💅

okay so bestie, welcome to struct xe_devcoredump(9), aka the Xe devcoredump main structure — this is the literal main character of the Xe devcoredump situation and we're gonna learn her together 🫶

---

🌸 NAME 🌸

struct xe_devcoredump — the Xe devcoredump main structure. that's it, that's the name, no notes ✨

---

🦋 SYNOPSIS 🦋

struct xe_devcoredump {
    struct mutex lock;
    bool captured;
    struct xe_devcoredump_snapshot snapshot;
 };

like… look at her. three members. immaculate. not a single wasted line 💅

---

🎀 Members 🎀

okay so let's meet the squad, one by one:

• lock — a struct mutex that protects access to the entire structure. she is the bouncer at the door of this whole struct, no cap 🔒
• captured — a bool that's all about one thing: the snapshot of the first hang has already been taken. yes bestie, the first one. we're keeping receipts of the og crash 📸
• snapshot — a struct xe_devcoredump_snapshot, and this baby is captured at the time of the first crash. it's giving crime scene evidence but make it kernel 🕵️‍♀️

---

💖 Description 💖

so here's the vibe check: this struct represents the live and active dev_coredump node 🔥

she gets created/populated at the time of a crash/error — like, the moment things go sideways, she's already on the scene, main character energy fr fr. then she just… chills. and later, when a user accesses the device coredump data file to read the information, that's when she gets read 📖✨

created at crash time, read at access time. the way that she just *works*… obsessed 😭💜

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpu/drm/xe/xe_devcoredump_types.h
• struct xe_devcoredump_snapshot(9)

go read those too bestie, iykyk 👑

ngl this is the good stuff — everything above is straight from the source, so don't come for me if you skimmed it 🙈

---

and that's the whole page, bestie!! 🦋 the tea came from ./drivers/gpu/drm/xe (yes, that exact path, no typo), dated October 2026, and it's the struct xe_devcoredump(9) page from the Kernel API Manual 💖 slay, you're now unironically a devcoredump expert, periodt ✨🎀
