📦 version 7.3.1, in nixpkgs unstable

💅 host1x_syncpt_request(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, don't @ me — and today's main character is host1x_syncpt_request. she's short, she's sweet, she gets you a syncpoint. let's go ✨

🌸 NAME 🌸

host1x_syncpt_request — request a syncpoint 🎀

✨ SYNOPSIS ✨

struct host1x_syncpt * host1x_syncpt_request (struct host1x_client
*client , unsigned long flags );

🦋 ARGUMENTS 🦋

  • client — the client that's requesting the syncpoint. yeah. that one. the one doing the asking 💅
  • flags — flags. that's it. that's the description. flags. iconic honestly 👑

💖 DESCRIPTION 💖

so here's the vibe: host1x client drivers can use this function to allocate a syncpoint for subsequent use. literally what it says on the tin, no cap 🫶

and here's the part you actually need to remember: a syncpoint returned by this function will be reserved for use by the client exclusively. it's yours, bestie. main character syncpoint. nobody else gets to touch it 💅✨

⚠️ when no longer using a syncpoint, a host1x client driver needs to release it using host1x_syncpt_put. don't just ghost it, okay?? release your syncpoints. that's the rule. 😭
