💅 jpeg_v1_dec_ring_parse_cs(9) — the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the Kernel API Manual ✨ and specifically to jpeg_v1_dec_ring_parse_cs(9) — yes that whole entire name, say it with your chest 🫶

🎀 NAME 🎀

jpeg_v1_dec_ring_parse_cs — the command submission parser, literally that's her job description 📋

✨ SYNOPSIS ✨

int jpeg_v1_dec_ring_parse_cs (struct amdgpu_cs_parser *parser , struct
amdgpu_job *job , struct amdgpu_ib *ib );

three struct pointers in, one int out. iconic signature, no notes 💅

🌸 ARGUMENTS 🌸

  • parser — the command submission parser context 🧠 this is the main character, the whole vibe of the operation lives here
  • job — the job to parse ⚙️ the actual work unit getting inspected
  • ib — the IB to parse 📦 the indirect buffer in question, she's getting looked at too

🦋 DESCRIPTION 🦋

So what does she do? She parses the command stream 💫 that's it, that's the plot.

And the return value? Big deal, pay attention:

  • if the packet is invalid, she hits you with -EINVAL 💀
  • otherwise, you get 0 — success, slay, we move 🎉
fr fr that's the whole contract: invalid packet → -EINVAL, everything else → 0. No cap.
