STRUCT DPU_ENC_PHYS_INIT_PARAMS(9)

💫 struct dpu_enc_phys_init_params — kernel API manual energy 💫

okay so bestie, we're in the Kernel API Manual (section 9, for the curious 👑) and today's main character is struct dpu_enc_phys_init_params — literally the initialization parameters for phys encs ✨ like, it's giving "here's the starter pack for your physical encoder" 🎀

---

🌸 NAME 🌸

struct dpu_enc_phys_init_params — initialization parameters for phys encs 💅

---

✨ SYNOPSIS ✨

struct dpu_enc_phys_init_params {
    struct dpu_kms *dpu_kms;
    struct drm_encoder *parent;
    enum dpu_enc_split_role split_role;
    struct dpu_hw_intf *hw_intf;
    struct dpu_hw_wb *hw_wb;
    spinlock_t *enc_spinlock;
 };

no cap, that's the whole shape of it 🫶 copy it exactly, don't be cute with it.

🦋 Members 🦋

• dpu_kms — pointer to the dpu_kms top level 👑 like, your main character reference fr fr
• parent — pointer to the containing virtual encoder 🧚 it's the parent, it contains, you get it
• split_role — the role to play in a split-panel configuration 🌈 everybody's got a part in the group chat
• hw_intf — hardware interface to the intf registers ⭐
• hw_wb — hardware interface to the wb registers 💜
• enc_spinlock — the Virtual-Encoder-Wide Spin Lock for IRQ purposes 🔥 lock it down bestie, IRQs are not playing

ngl, that spinlock line is doing a lot of heavy lifting — it's virtual-encoder-wide and it's for IRQ purposes, so don't go thinking it's just any old lock 💀

and like, a proper sign-off because we're classy: this one comes to you from ./drivers/gpu/drm/msm/disp/dpu1 🍓, dated October 2026 ⭐, sitting pretty in the Kernel API Manual under struct dpu_..._init_params(9) 💜 slay, bye 💅✨
