ENUM TEST_PATTERN(9)

🦋 enum test_pattern(9) 🦋

🌈 NAME 💖

enum test_pattern — literally Test patterns for test testing 🧪✨ and yes bestie, this is the Kernel API Manual page for it. It’s giving enum energy, it’s giving test-pattern couture, and it’s lowkey exactly what it says on the tin 💅

✨ SYNOPSIS ✨

okay so here’s the whole enum, no cap:

enum test_pattern {
    TEST_VIDEO ,
    TEST_TPS1 ,
    TEST_TPS2 ,
    TEST_TPS3 ,
    TEST_SYMBOL_ERROR ,
    TEST_PRBS7 ,
    TEST_80BIT_CUSTOM ,
    TEST_CP2520

};

🎀 Constants 🎀

these are the constants, bestie — memorise the vibes and the exact names 💖

• TEST_VIDEO — use regular video input 🎥
• TEST_TPS1 — link training symbol pattern TPS1 (/D10.2/) 🦋
• TEST_TPS2 — link training symbol pattern TPS2 ✨
• TEST_TPS3 — link training symbol pattern TPS3 (for HBR2) 💫
• TEST_SYMBOL_ERROR — symbol error measurement pattern 😭
• TEST_PRBS7 — output of the PRBS7 (x^7 + x^6 + 1) polynomial 🌸
• TEST_80BIT_CUSTOM — a custom 80-bit pattern 🎀
• TEST_CP2520 — HBR2 compliance eye pattern 👑
