STRUCT DRM_MODE_DESTROY_BLOB(9)

💅 struct drm_mode_destroy_blob(9) — Kernel API Manual (yes, the manual manual, bestie) 🎀

okay so picture this: it's a whole kernel API manual page, the header literally says struct drm_mode_destroy_blob(9) and everything. buckle up 🦋

✨ NAME ✨

struct drm_mode_destroy_blob — Destroy user blob 💀✨

🌸 SYNOPSIS 🌸

struct drm_mode_destroy_blob {
    __u32 blob_id;
 };

🧚 Members 🧚

• blob_id — the blob_id you're about to destroy. that's it, that's the member 🫶

💖 Description 💖

So you've got yourself a user-created blob property and you need it gone. This is the struct for that. Destroy a user-created blob property, periodt 🔥

The key thing — and this is the part that ate — user-space can release blobs as soon as they don't need to refer to them by their blob object ID anymore. Like, the moment you're not using that ID, you can yeet the blob. No cap.

For instance: if you're using a MODE_ID blob in an atomic commit and you will not make another commit re-using the same ID, you can destroy the blob as soon as the commit has been issued, without waiting for it to complete. the way that works is genuinely iconic — you don't have to sit there waiting for the commit to finish before you clean up 👑

ngl this one's a nice little struct, super lowkey, main character energy in its simplicity 🌈
