STRUCT DRM_WRITEBACK_JOB(9)

✨ struct drm_writeback_job(9) ✨

okay so bestie, this is the Kernel API Manual entry for struct drm_writeback_job — literally the DRM writeback job itself 💅 it's the lil struct that holds everything a writeback connector needs to know about a job, and we're gonna go through every single member, no skipping, periodt.

🦋 SYNOPSIS 🦋

struct drm_writeback_job {
    struct drm_writeback_connector *connector;
    bool prepared;
    struct work_struct cleanup_work;
    struct list_head list_entry;
    struct drm_framebuffer *fb;
    struct dma_fence *out_fence;
    void *priv;
 };

💅 Members 💅

• connector — back-pointer to the writeback connector that this job belongs to 🫶 it's giving "know your roots" energy, iykyk.
• prepared — a bool that gets set when the job has been prepared with drm_writeback_prepare_job ✨ so like, it's the little flag that says "yep, we're prepped."
• cleanup_work — a struct work_struct that exists so drm_writeback_signal_completion can defer dropping the framebuffer reference onto a workqueue 🧚 lowkey iconic delegation behavior.
• list_entry — the list item for the writeback connector's job_queue 🎀 it's how the job hangs out in the queue with all its friends.
• fb — the framebuffer that the writeback connector is gonna write to 🖼️ but listen: do not set this directly, use drm_writeback_set_fb instead. no cap, don't touch it yourself.
• out_fence — the fence that will signal once the writeback has completed ⭐ like a little "we're done here!" notification.
• priv — driver-private data 🙈 whatever the driver wants to stash in there, it's all yours.

and that's the whole vibe check, bestie 💖 this page came from ./include/drm, October 2026, and yes — it's still titled struct drm_writeback_job(9) at the very bottom too, slay 🎀✨
