ENUM FE_CAPS(9)

💖 NAME 💖

enum fe_caps — the frontend capabilities enum, aka the whole "what can this tuner actually do" glow-up list, bestie. This one lives in the Kernel API Manual, and it's giving pure "let me tell you what I'm capable of" energy. ✨

Like, that's the whole roster. Every constant is a little vibe check for the hardware 👑

🎀 Constants 🎀

Okay so here's the tea on each and every one of these, no skips, no cuts 💅

• FE_IS_STUPID — bestie, something is wrong at the frontend and it literally cannot report its capabilities. It's not you, it's it. 😭
• FE_CAN_INVERSION_AUTO — can auto-detect frequency spectral band inversion ✨
• FE_CAN_FEC_1_2 — supports FEC 1/2 🫶
• FE_CAN_FEC_2_3 — supports FEC 2/3 🫶
• FE_CAN_FEC_3_4 — supports FEC 3/4 🫶
• FE_CAN_FEC_4_5 — supports FEC 4/5 🫶
• FE_CAN_FEC_5_6 — supports FEC 5/6 🫶
• FE_CAN_FEC_6_7 — supports FEC 6/7 🫶
• FE_CAN_FEC_7_8 — supports FEC 7/8 🫶
• FE_CAN_FEC_8_9 — supports FEC 8/9 🫶
• FE_CAN_FEC_AUTO — can auto-detect FEC, so you don't gotta 🦋
• FE_CAN_QPSK — supports QPSK modulation 💫
• FE_CAN_QAM_16 — supports 16-QAM modulation ⭐
• FE_CAN_QAM_32 — supports 32-QAM modulation ⭐
• FE_CAN_QAM_64 — supports 64-QAM modulation ⭐
• FE_CAN_QAM_128 — supports 128-QAM modulation ⭐
• FE_CAN_QAM_256 — supports 256-QAM modulation ⭐
• FE_CAN_QAM_AUTO — can auto-detect QAM modulation, main character energy fr fr 🌈
• FE_CAN_TRANSMISSION_MODE_AUTO — can auto-detect transmission mode 🔥
• FE_CAN_BANDWIDTH_AUTO — can auto-detect bandwidth 🔥
• FE_CAN_GUARD_INTERVAL_AUTO — can auto-detect guard interval 🔥
• FE_CAN_HIERARCHY_AUTO — can auto-detect hierarchy 🔥
• FE_CAN_8VSB — supports 8-VSB modulation 🎀
• FE_CAN_16VSB — supports 16-VSB modulation 🎀
• FE_HAS_EXTENDED_CAPS — unused 🙈 (yes literally, it's just sitting there, iconic for doing nothing)
• FE_CAN_MULTISTREAM — supports multistream filtering 🌸
• FE_CAN_TURBO_FEC — supports "turbo FEC" modulation 🏎️✨
• FE_CAN_2G_MODULATION — supports "2nd generation" modulation, e. g. DVB-S2, DVB-T2, DVB-C2 👑
• FE_NEEDS_BENDING — unused 🙈 (also just vibing, doing absolutely nothing)
• FE_CAN_RECOVER — can recover from a cable unplug automatically, the way it just bounces back 😭💜
• FE_CAN_MUTE_TS — can stop spurious TS data output, silencing the chaos 🤫

Go read those too, iykyk 💅

ngl bestie, a couple of these are literally marked unused in the source. That's not me being shady, that's just what it says. 🫶

mwah, that's the whole page 💜 straight from ./include/uapi/linux/dvb, dated October 2026 in the Kernel API Manual — slay, go forth and probe your frontend, periodt 🎀🦋✨
