STRUCT DRXK_CONFIG(9)

💖 struct drxk_config(9) — Kernel API Manual 💖

okay so bestie, this is the page for struct drxk_config, and it's literally the little config bundle that tells DRX-K how to show up at the start. We're keeping all the facts, just with way more sparkle ✨ and honestly? obsessed.

💖 NAME 💖

struct drxk_config — Configure the initial parameters for DRX-K 🎀

✨ SYNOPSIS ✨

Here's the struct in all its exact glory, no cap:

       struct drxk_config {
           u8 adr;
           bool single_master;
           bool no_i2c_bridge;
           bool parallel_ts;
           bool dynamic_clk;
           bool enable_merr_cfg;
           bool antenna_dvbt;
           u16 antenna_gpio;
           u8 mpeg_out_clk_strength;
           int chunk_size;
           const char      *microcode_name;
           int qam_demod_parameter_count;
        };

🎀 Members 🎀

• adr — I2C address of the DRX-K. That's where it lives on the bus 💅
• single_master — Device is on the single master mode. Yes, it's giving solo-main-character energy 👑
• no_i2c_bridge — Don't switch the I2C bridge to talk with tuner. Like, leave the bridge alone, bestie 🙈
• parallel_ts — True means that the device uses parallel TS, Serial otherwise. Very "choose your transport vibe" ✨
• dynamic_clk — True means that the clock will be dynamically adjusted. Static clock otherwise. So it's either dynamic or static, periodt ⏰
• enable_merr_cfg — Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG. That's the exact pair, don't come for me 🫶
• antenna_dvbt — GPIO bit for changing antenna to DVB-C. A value of 1 means that 1=DVBC, 0 = DVBT. Zero means the opposite. Yes, this one is a little brain-bender, but that's the spec 😭
• antenna_gpio — GPIO bit used to control the antenna. The antenna's remote control, basically 🎀
• mpeg_out_clk_strength — DRXK Mpeg output clock drive strength. Fancy clock muscles 💪
• chunk_size — maximum size for I2C messages. Keep those messages in cute lil chunks 🍓
• microcode_name — Name of the firmware file with the microcode. That's the firmware's government name, iykyk 🧚
• qam_demod_parameter_count — The number of parameters used for the command to set the demodulator parameters. All firmwares are using the 2-parameter command. An exception is the drxk_a3.mc firmware, which uses the 4-parameter command. A value of 0 (default) or lower indicates that the correct number of parameters will be automatically detected. So yes, 0 or lower means "bestie, figure it out" 🔥

🌸 Description 🌸

On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is UIO-3. So that's the bit map, fr fr 🗺️✨
