💅 cik_tiling_mode_table_init(9) — the Kernel API Manual glow-up

okay bestie, so this one lives in the Kernel API Manual, and no cap it's a cute little hardware-setup function. let's get into it 🎀

✨ NAME ✨

cik_tiling_mode_table_init — literally just here to init the hw tiling table. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

void cik_tiling_mode_table_init (struct radeon_device *rdev );

like, it returns nothing (void), it takes one thing, and it does its little job. periodt. 💅

🧚 ARGUMENTS 🧚

  • rdev — a radeon_device pointer. that's it, that's the whole parameter list. she's low-maintenance, we stan 🫶

👑 DESCRIPTION 👑

okay so here's the lore 🔥 starting with SI, the tiling setup got done globally in a set of 32 tiling modes. so instead of hand-picking each set of parameters per surface like on the older asics did 🙈, we just select which index in the tiling table we wanna use, and the surface uses those parameters (CIK). iconic behavior honestly — one table, many indexes, zero per-surface chaos ✨

💖 SEE ALSO 💖

first up, the kernel file itself (the source of truth, the main character):

and now the whole friend group 😭 — every single one of these, no skipping:
