STRUCT DDR_DEVICE_INFO(9)

💖 struct ddr_device_info(9) — Kernel API Manual 💖

okay bestie, welcome to the struct ddr_device_info(9) page 🫶 it’s literally giving “all the information about the DDR device except AC timing parameters.” That’s the whole NAME vibe, no cap 💅

✨ NAME ✨

struct ddr_device_info — all information about the DDR device except AC timing parameters 💖

🦋 SYNOPSIS 🦋

       struct ddr_device_info {
           u32 type;
           u32 density;
           u32 io_width;
           u32 cs1_used;
           u32 cal_resistors_per_cs;
           char manufacturer[10];
        };

🌸 Members 🌸

• type — device type, like LPDDR2-S4, LPDDR2-S2, etc. iykyk 🧚
• density — device density. that’s the tea 🍓
• io_width — bus width. slay ✨
• cs1_used — whether there is a DDR device attached to the second chip-select (CS1) of this EMIF instance 👑
• cal_resistors_per_cs — whether there is one calibration resistor per chip-select or whether it’s a single one for both 💅
• manufacturer — manufacturer name string. iconic 🎀
