💅 XE_RTP_ACTION_WR(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little macro from the xe driver's RTP (register table programming) world, and honestly? she's lowkey iconic. she writes a value to a register and overrides all the bits, no cap 👑

🌸 NAME 🌸

XE_RTP_ACTION_WR — the helper that writes a value to the register, overriding all the bits 🎀

like, all of them. every single bit. she does not share the register with anybody. main character energy fr fr.

✨ SYNOPSIS ✨

XE_RTP_ACTION_WR (reg_ , val_ , ... );

🦋 ARGUMENTS 🦋

  • reg_ — the register 🌈 (yes, that's the whole description, she's a simple girl)
  • val_ — the value to set 💖
  • ... — extra fields you wanna override in the struct xe_rtp_action entry — a little sprinkle of customization, iykyk 🧚

🔥 DESCRIPTION 🔥

so the whole point of this one: the correspondent notation in bspec is literally just

REGNAME = VALUE

and that's it. that's the vibe. REGNAME = VALUE, register gets the value, bits get overridden, we move on. periodt 💅✨

ngl she's a short manpage but she ATE. don't come for her for being brief, she's been booked and busy since October 2026 🫶
