STRUCT HL_STATE_DUMP_SPECS_FUNCS(9)

🎀 struct hl_state_dump_specs_funcs — NAME 🎀

okay so bestie, welcome to the Kernel API Manual page for struct hl_state_dump_specs_funcs(9) — literally the virtual functions used by the state dump. yes. a struct full of function pointers, and it is THE moment for the state dump. 💅

---

✨ SYNOPSIS ✨

no cap, here's the whole thing, character-for-character, go off:

struct hl_state_dump_specs_funcs {
    int (*gen_sync_to_engine_map)(struct hl_device *hdev, struct hl_sync_to_engine_map *map);
    int (*print_single_monitor)(char **buf, size_t *size, size_t *offset, struct hl_device *hdev, struct hl_mon_state_dump *mon);
    int (*monitor_valid)(struct hl_mon_state_dump *mon);
    int (*print_fences_single_engine)(struct hl_device *hdev, u64 base_offset, u64 status_base_offset, enum hl_sync_engine_type engine_type, u32 engine_id, char **buf, size_t *size, size_t *offset);
};

like… four whole function pointers. she's compact. she's powerful. she's giving pluggable-architecture main character energy. 👑

🌸 Members 🌸

bestie these are the four slots, and each one is a vibe with a job. listen:

• gen_sync_to_engine_map — generate a hash map from sync obj id to its engine. yeah. that's the whole job. it's the matchmaker of the struct — sync obj id on one side, engine on the other. 🔥
• print_single_monitor — format monitor data as string. one monitor in, one cute string out. it's giving "make it readable for the humans". ✨
• monitor_valid — return true if given monitor dump is valid. the vibe check function. is this monitor dump valid? true or false, no in-between, periodt. 🫶
• print_fences_single_engine — format fences data as string. fences data, single engine, formatted, string. same energy as above but make it fences. 💖

okay that's the whole page bestie — go read the headers, they slay. 💜

this cutie came to you from ./drivers/accel/habanalabs/common, dated October 2026, and she's filed under struct hl_st..._specs_funcs(9). mwah. 🎀✨🍓
