💅 xe_map_resource_to_region(9) 💅

ok so welcome to the Kernel API Manual bestie, today's main character is xe_map_resource_to_region(9) — say that five times fast, i literally cannot 🫶

✨ NAME ✨

xe_map_resource_to_region — maps a ttm resource to a vram memory region. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

struct xe_vram_region * xe_map_resource_to_region (struct ttm_resource
*res );

like, one function, one pointer in, one pointer out. no cap, it's giving minimalism 👑

---

🦋 ARGUMENTS 🦋

• res — the ttm resource. that's the one and only thing you hand it, and honestly? she's enough 💅

---

⭐ DESCRIPTION ⭐

okay so here's the tea ☕ — this function gets you the vram memory region by using the vram memory manager that's managing this resource. so like, you've got a res, she's got a manager, and the manager knows which vram region she belongs to, and bam 💥 that's what you get back. it's giving "asking your friend who knows a guy" energy, iykyk 🧚

---

🔥 RETURN 🔥

a pointer to xe_vram_region. that's the whole return value, periodt 💖

🌈 SEE ALSO 🌈

so like, go read the kernel file ./drivers/gpu/drm/xe/xe_vram.c and then these iconic siblings of hers, ok? they all ate:

• xe_vram_probe(9)
• xe_vram_region_io_start(9)
• xe_vram_region_io_size(9)
• xe_vram_region_dpa_base(9)
• xe_vram_region_usable_size(9)
• xe_vram_region_actual_physical_size(9)

ngl that's a whole friend group and every single one of them is serving 🌸

literally just one function, but she's lowkey important, don't skip the SEE ALSO list bestie 🙈

and that's a wrap!! this page lives in ./drivers/gpu/drm/xe, dated October 2026, and it's the xe_map_resource_to_region(9) page from the Kernel API Manual — slay, bye, drink some water 💜🦋✨
