STRUCT DPU_INTF_CFG(9)

welcome to the struct dpu_intf_cfg(9) page from the Kernel API Manual, bestie 💖 this one is short, iconic, and ready to spill the tea.

💖 NAME 💖

okay so struct dpu_intf_cfg is literally the information of timing engine blocks ✨ @id is the enum identifying this block, and @base is the register offset of this block. that's the whole plot, no cap 🎀

✨ SYNOPSIS ✨

here's the struct in all her main-character glory, copy-paste energy and all:

       struct dpu_intf_cfg {
           DPU_HW_BLK_INFO;
           u32 type;
           u32 controller_id;
           u32 prog_fetch_lines_worst_case;
           unsigned int intr_underrun;
           unsigned int intr_vsync;
           unsigned int intr_tear_rd_ptr;
        };

• type — Interface type (DSI, DP, HDMI) 💅
• controller_id — Controller Instance ID in case of multiple of intf type
• prog_fetch_lines_worst_case — Worst case latency num lines needed to prefetch
• intr_underrun — index for INTF underrun interrupt
• intr_vsync — index for INTF VSYNC interrupt
• intr_tear_rd_ptr — Index for INTF TEAR_RD_PTR interrupt
