ttm_agp_tt_create(9)

Kernel API Manual bestie, we're talking about ttm_agp_tt_create(9) — it's giving kernel API realness, and the whole page is about making a TTM backend that uses an AGP bridge as an aperture for TT memory ✨💅

💖 NAME 💖

ttm_agp_tt_create — the dash is literally sitting there with no extra one-liner after it, so that's the whole NAME vibe, bestie 😭🫶

🌸 SYNOPSIS 🌸

       struct ttm_tt * ttm_agp_tt_create (struct ttm_buffer_object *bo , struct
       agp_bridge_data *bridge , uint32_t page_flags );

✨ ARGUMENTS ✨

• bo — Buffer object we allocate the ttm for. That's the assignment, no cap 🫶
• bridge — The agp bridge this device is sitting on. Like, which bridge it's vibing on 💅
• page_flags — Page flags as identified by TTM_TT_FLAG_XX flags. Those exact flags, fr fr ✨

🦋 DESCRIPTION 🦋

Okay so this function creates a TTM backend that uses the indicated AGP bridge as an aperture for TT memory. It uses the linux agpgart interface to bind and unbind memory backing a ttm_tt. That's the tea ☕ no cap.
