💖 xe_bo_create_user(9) 💖

Okay bestie, welcome to the Kernel API Manual page for xe_bo_create_user(9). This is the one that creates a user BO, and we’re gonna read it together like the group chat is watching. ✨

🌸 NAME 🌸

xe_bo_create_user — Create a user BO

🦋 SYNOPSIS 🦋

struct xe_bo * xe_bo_create_user (struct xe_device *xe , struct xe_vm
       *vm , size_t size , u16 cpu_caching , u32 flags , struct drm_exec *exec
       );

🎀 ARGUMENTS 🎀

Here’s the cast — every single argument, no skips, periodt:

  • xe — The xe device. Main character energy, lowkey.
  • vm — The local vm, or NULL for external objects. 👀
  • size — The storage size to use for the bo.
  • cpu_caching — The caching mode to be used for system backing store.
  • flags — XE_BO_FLAG_ flags.
  • exec — The drm_exec transaction to use for exhaustive eviction, or NULL if such a transaction should be initiated by the call.

✨ DESCRIPTION ✨

Create a bo on behalf of user-space. Literally that’s the description — this function does the BO-making for user-space. 🫶

🔥 RETURN 🔥

The buffer object on success. Negative error pointer on failure.

So yeah: success gives you the buffer object, failure gives you a negative error pointer — and that’s the vibe check. 💅

🌈 SEE ALSO 🌈
