💅 syncpt_assign_to_channel(9) — Kernel API Manual 💅

Okay so this is the page for syncpt_assign_to_channel(9), straight from the Kernel API Manual, and it's all about assigning a syncpoint to a channel. Bestie, it's short, it's useful, and it ate. ✨

💖 NAME 💖

syncpt_assign_to_channel — Assign syncpoint to channel

🌸 SYNOPSIS 🌸

void syncpt_assign_to_channel (struct host1x_syncpt *sp , struct
       host1x_channel *ch );

🎀 ARGUMENTS 🎀

• sp — syncpoint. The syncpoint in question, bestie.
• ch — channel. The channel that's getting the syncpoint.

🦋 DESCRIPTION 🦋

Okay so on chips with the syncpoint protection feature (Tegra186+), this assigns sp to ch, preventing other channels from incrementing the syncpoints. If ch is NULL, it unassigns the syncpoint. No cap, that's the whole assignment moment. 👑

On older chips, do nothing. Literally nothing. It's giving "not my era" and honestly? Fair. 💀

• Kernel file ./drivers/gpu/host1x/hw/syncpt_hw.c — the source file to go look at.
• syncpt_enable_protection(9) — another manual page in the mix.
