drm_gem_lock_reservations(9)

🌸 NAME 🌸

okay so bestie, this is the Kernel API Manual page for drm_gem_lock_reservations(9), and it sets up the ww context and acquires the lock on an array of GEM objects. that's the whole serve, no cap. 💅✨

✨ SYNOPSIS ✨

int drm_gem_lock_reservations (struct drm_gem_object **objs , int count
       , struct ww_acquire_ctx *acquire_ctx );

🎀 ARGUMENTS 🎀

• objs — the drm_gem_objects to lock. 👑
• count — the number of objects in objs. literally just the count, bestie.
• acquire_ctx — a struct ww_acquire_ctx that will be initialized as part of tracking this set of locked reservations. it's giving lock-tracking main character energy. 🦋

💖 DESCRIPTION 💖

so once you've locked your reservations, bestie, you'll want to set up space for your shared fences (if applicable), submit your job, and then call drm_gem_unlock_reservations. that's the sequence — slay it in order. ✨🔥
