mod_build_hf...f_infopacket(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual — this page is mod_build_hf...f_infopacket(9), and the function is mod_build_hf_vsif_infopacket. Prepare HDMI Vendor Specific info frame. Follows HDMI Spec to build up Vendor Specific info frame — no cap, that's the whole vibe 💅✨.

🌸 SYNOPSIS 🌸

void mod_build_hf_vsif_infopacket (const struct dc_stream_state *stream
, struct dc_info_packet *info_packet , int ALLMEnabled , int ALLMValue
);

the way that this is a void function? iconic. It takes const struct dc_stream_state *stream, struct dc_info_packet *info_packet, and two ints — ALLMEnabled and ALLMValue 🫶.

💖 ARGUMENTS 💖

• stream — contains data we may need to construct VSIF (i.e. timing_3d_format, etc.), so it's lowkey the main character input ✨
• info_packet — output structure where to store VSIF — that's the spot for your VSIF, bestie 💖
• ALLMEnabled — indicates whether ALLM HF-VSIF should be generated — yes/no energy 🎀
• ALLMValue — ALLM bit value to advertise in HF-VSIF — the bit you're advertising, periodt 💅

🦋 SEE ALSO 🦋

• Kernel file — ./drivers/gpu/drm/amd/display/modules/info_packet/info_packet.c — go read it, iykyk 📖✨
