💖 drm_pagemap_evict_to_ram(9) 💖

okay so bestie, welcome to the Kernel API Manual page for drm_pagemap_evict_to_ram — it's giving “evict this GPU SVM range to RAM” and honestly? iconic. 💅

🌸 NAME 🌸

drm_pagemap_evict_to_ram — Evict GPU SVM range to RAM

✨ SYNOPSIS ✨

int drm_pagemap_evict_to_ram (struct drm_pagemap_devmem
*devmem_allocation );

🎀 ARGUMENTS 🎀

• devmem_allocation — pointer to the device memory allocation. that's the pointer you're handing over, bestie 🫶

💅 DESCRIPTION 💅

So this one is similar to __drm_pagemap_migrate_to_ram, but it uses the migrate_device_* helpers and does not require the mmap lock. no cap, that lock is not invited to this party 🙈

Also: device-private PFNs already migrated to RAM by either path are skipped. like, “been there, done that, not doing it again” energy. skipped. periodt. ✨

🦋 RETURN 🦋

0 on success, negative error code on failure. that's the whole vibe check: 0 means slay, negative means something went wrong and you get an error code 😭
