📦 version 7.3.1, in nixpkgs unstable

💖 gfx_v8_0_get_hdp_flush_mask(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual, and honestly? it's a little baby function that does one very specific thing and does it slay. let's get into it ✨

🌸 NAME 🌸

gfx_v8_0_get_hdp_flush_mask — get the reference and mask for HDP flush 🫶

like, that's literally the whole job. it gets you the reference and the mask for the HDP flush. no cap.

🦋 SYNOPSIS 🦋

void gfx_v8_0_get_hdp_flush_mask (struct amdgpu_ring *ring , uint32_t
*ref_and_mask , uint32_t *reg_mem_engine );

notice the return type is void — this one's not giving you anything back directly, it's the pointer main character energy. you pass in pointers and it fills them in. iykyk 💅

🎀 ARGUMENTS 🎀

  • ring — this is the amdgpu_ring structure that's holding all the ring information. it's the whole vibe check for what happens next 💜
  • ref_and_mask — a pointer where the reference and mask get stored. yes, both. together. iconic.
  • reg_mem_engine — a pointer to store the register memory engine in. very demure, very mindful, very pointer 💖

⭐ DESCRIPTION ⭐

so what does it actually do? it calculates the reference and mask for HDP flush — and the way it does that is based on the ring type and me. that's it, that's the whole calculation. it's giving "small function, big responsibility" 🔥

ngl, it's a short description for a short function, and we respect that. not every function needs a whole saga. periodt. 👑
