ENUM NFC_ATTRS(9)

🌸 ENUM NFC_ATTRS 🌸

okay bestie, gather round, because this is the enum nfc_attrs page from the Kernel API Manual and it's literally the master list of supported nfc attributes. think of it as the group chat roster for NFC stuff in the kernel — every attribute that gets to be in the enum is listed here, no gatekeeping 💅

✨ SYNOPSIS ✨

here's the whole enum, exactly as it lives in the source — do not touch, do not "fix", just vibe with it:

enum nfc_attrs {
    NFC_ATTR_UNSPEC ,
    NFC_ATTR_DEVICE_INDEX ,
    NFC_ATTR_DEVICE_NAME ,
    NFC_ATTR_PROTOCOLS ,
    NFC_ATTR_TARGET_INDEX ,
    NFC_ATTR_TARGET_SENS_RES ,
    NFC_ATTR_TARGET_SEL_RES ,
    NFC_ATTR_TARGET_NFCID1 ,
    NFC_ATTR_TARGET_SENSB_RES ,
    NFC_ATTR_TARGET_SENSF_RES ,
    NFC_ATTR_COMM_MODE ,
    NFC_ATTR_RF_MODE ,
    NFC_ATTR_DEVICE_POWERED ,
    NFC_ATTR_IM_PROTOCOLS ,
    NFC_ATTR_TM_PROTOCOLS ,
    NFC_ATTR_LLC_PARAM_LTO ,
    NFC_ATTR_LLC_PARAM_RW ,
    NFC_ATTR_LLC_PARAM_MIUX ,
    NFC_ATTR_SE ,
    NFC_ATTR_LLC_SDP ,
    NFC_ATTR_FIRMWARE_NAME ,
    NFC_ATTR_SE_INDEX ,
    NFC_ATTR_SE_TYPE ,
    NFC_ATTR_SE_AID ,
    NFC_ATTR_FIRMWARE_DOWNLOAD_STATUS ,
    NFC_ATTR_SE_APDU ,
    NFC_ATTR_TARGET_ISO15693_DSFID ,
    NFC_ATTR_TARGET_ISO15693_UID ,
    NFC_ATTR_SE_PARAMS ,
    NFC_ATTR_VENDOR_ID ,
    NFC_ATTR_VENDOR_SUBCMD ,

    NFC_ATTR_TARGET_ATS

};

🎀 CONSTANTS 🎀

okay so now the actual lore, one attribute at a time. no skips, we're reading the whole syllabus 📚✨

• NFC_ATTR_UNSPEC — the unspecified attribute. it's giving "no thoughts, head empty" placeholder energy 🙈
• NFC_ATTR_DEVICE_INDEX — index of the nfc device. it's the device's little ID number 🎫
• NFC_ATTR_DEVICE_NAME — device name, and heads up: max 8 chars. eight. that's it. keep it cute and short 🍓
• NFC_ATTR_PROTOCOLS — nfc protocols, as a bitwise or-ed combination from the NFC_PROTO_*_MASK constants. mix and match, bestie 🌈
• NFC_ATTR_TARGET_INDEX — index of the nfc target 🎯
• NFC_ATTR_TARGET_SENS_RES — NFC-A targets extra information such as NFCID ✨
• NFC_ATTR_TARGET_SEL_RES — NFC-A targets extra information, and the manpage literally says it's useful if the target is not NFC-Forum compliant — so like, for the rebels 💀
• NFC_ATTR_TARGET_NFCID1 — NFC-A targets identifier, max 10 bytes 🔟
• NFC_ATTR_TARGET_SENSB_RES — NFC-B targets extra information, max 12 bytes 💙
• NFC_ATTR_TARGET_SENSF_RES — NFC-F targets extra information, max 18 bytes 🌸
• NFC_ATTR_COMM_MODE — passive or active mode. pick your era 👑
• NFC_ATTR_RF_MODE — initiator or target. are you the one sliding into the DMs or the one receiving? 👀
• NFC_ATTR_DEVICE_POWERED — -- undescribed --. yeah. the manpage said nothing. we know nothing. iconically mysterious 🫥
• NFC_ATTR_IM_PROTOCOLS — initiator mode protocols to poll for 📡
• NFC_ATTR_TM_PROTOCOLS — target mode protocols to listen for 👂
• NFC_ATTR_LLC_PARAM_LTO — Link TimeOut parameter ⏳
• NFC_ATTR_LLC_PARAM_RW — Receive Window size parameter 🪟
• NFC_ATTR_LLC_PARAM_MIUX — MIU eXtension parameter. the x is capitalized, respect it ✖️
• NFC_ATTR_SE — Available Secure Elements 🔐
• NFC_ATTR_LLC_SDP — -- undescribed -- again. the void stares back 🕳️
• NFC_ATTR_FIRMWARE_NAME — Free format firmware version. free format means go off, no rules 🎨
• NFC_ATTR_SE_INDEX — secure element index 🔢
• NFC_ATTR_SE_TYPE — secure element type, and the options are (UICC or EMBEDDED) 💳
• NFC_ATTR_SE_AID — -- undescribed --. third mystery of the page, we love a cryptic queen 🙈
• NFC_ATTR_FIRMWARE_DOWNLOAD_STATUS — firmware download operation status 📥
• NFC_ATTR_SE_APDU — secure element APDU 📨
• NFC_ATTR_TARGET_ISO15693_DSFID — ISO 15693 Data Storage Format Identifier 🏷️
• NFC_ATTR_TARGET_ISO15693_UID — ISO 15693 Unique Identifier. unique, like you 🦋
• NFC_ATTR_SE_PARAMS — parameters data from an evt_transaction 📦
• NFC_ATTR_VENDOR_ID — NFC manufacturer unique ID, typically an OUI 🏭
• NFC_ATTR_VENDOR_SUBCMD — vendor specific sub command 🛠️
• NFC_ATTR_VENDOR_DATA — vendor specific data, to be optionally passed to a vendor specific command implementation. optional! no pressure 🫶
• NFC_ATTR_TARGET_ATS — ISO 14443 type A target Answer To Select. ATS, not the other thing 💬
