ENUM ICVS_COMMAND(9)

💖 NAME

okay so bestie, enum icvs_command is literally the protocol command opcodes — like, the whole menu of stuff you can ask the firmware to do, sitting up in firmware space 0x0800+ 💅 (this is the Kernel API Manual, section 9, btw 🎀)

✨ SYNOPSIS ✨

       enum icvs_command {
           ICVS_GET_DEV_STATE ,
           ICVS_GET_DEV_FW_VERSION ,
           ICVS_GET_DEV_VID_PID ,
           ICVS_GET_DEV_ERR_CODE ,
           ICVS_GET_DEV_CAPABILITY ,
           ICVS_SET_DEV_HOST_ID ,
           ICVS_GET_DEV_HOST_ID ,
           ICVS_FW_LOADER_START ,
           ICVS_FW_LOADER_DATA ,
           ICVS_FW_LOADER_END ,
           ICVS_HOST_GET_MIPI_CONFIG ,
           ICVS_HOST_SET_MIPI_CONFIG ,
           ICVS_HOST_SENSOR_OWNER

       };

🦋 Constants 🦋

okay so these are all the members, one by one, no skips, no cap 👑

• ICVS_GET_DEV_STATE — ask the device what state it's in rn, and you get it back as a state bitfield ✨
• ICVS_GET_DEV_FW_VERSION — pull the firmware version tuple, like a little name-tag for the fw 💖
• ICVS_GET_DEV_VID_PID — read the vendor / product identifiers, the classic VID/PID combo 🎀
• ICVS_GET_DEV_ERR_CODE — grab the last error code, if there even is one (if any 👀) 😭
• ICVS_GET_DEV_CAPABILITY — read the protocol capability structure, so you know what it can actually do 🫶
• ICVS_SET_DEV_HOST_ID — set the host identity / ownership bits, like planting your flag 🌸
• ICVS_GET_DEV_HOST_ID — read that host identity right back out, vibe check complete 🔥
• ICVS_FW_LOADER_START — kick off the firmware download sequence, here we gooo ⭐
• ICVS_FW_LOADER_DATA — stream one chunk of firmware payload, chunk by chunky chunk 🧚
• ICVS_FW_LOADER_END — end the firmware download and trigger the flash, the finale 💀
• ICVS_HOST_GET_MIPI_CONFIG — request the current MIPI CSI link configuration 📸
• ICVS_HOST_SET_MIPI_CONFIG — apply a brand-new MIPI CSI link configuration, slay 💅
• ICVS_HOST_SENSOR_OWNER — toggle CSI sensor ownership (with a lil GPIO assist) 👑
