💅 ice_update_fd_mask(9) — a Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today (yes, the (9) section, that's the kernel-internals girlies 💜) and the star of the show is ice_update_fd_mask. she's a little one, she's a vibe, and honestly she's giving "small function, big responsibilities" ✨

🌸 NAME 🌸

ice_update_fd_mask — set Flow Director Field Vector mask for a profile 🎀

✨ SYNOPSIS ✨

void ice_update_fd_mask (struct ice_hw *hw , u16 prof_id , u32 mask_sel );

no return value, no drama, she just does the thing 💅

🫶 ARGUMENTS 🫶

  • hw — pointer to the HW struct. literally the hardware's whole personality in one struct, and she needs it 👑
  • prof_id — profile ID. tells her which profile we're talking about, iykyk 🎀
  • mask_sel — mask select. the actual mask picker-outer, she's the main character here 🌟

🔥 DESCRIPTION 🔥

so what does she do? fr fr, she enables any of the masks selected by the mask_sel parameter — and she does it for the profile you named in prof_id. that's it, that's the whole job, and she ate 💅✨

like, you point her at the hardware (hw), you tell her which profile (prof_id), you hand her the mask select (mask_sel), and she goes and turns on whichever masks that select picked out. no cap 🧚
