xe_guc_klv_print_one(9)

💅 xe_guc_klv_print_one 💅

okay so bestie, welcome to the Kernel API Manual entry for xe_guc_klv_print_one — yes that's a mouthful, yes I say it in one breath, no I will not be elaborating 🎀

This little icon prints one single GuC KLV and honestly? she's serving exactly that. one job. one KLV. no notes.

---

✨ SYNOPSIS ✨

void xe_guc_klv_print_one (u16 key , u16 len , const u32 *value , struct
drm_printer *p );

like literally that's the whole signature, copy it exactly, don't @ me 💜

---

🌸 ARGUMENTS 🌸

• key — the KLV key, it's a u16 and it's the main character of this whole operation 👑
• len — the KLV length, and heads up it's counted in u32 dwords not bytes, so don't get cute with it 🫶
• value — the KLV value itself, handed over as an array of len u32 dwords, periodt 💅
• p — the drm_printer, aka where all this pretty output actually goes 🖨️✨

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check: the buffer may contain more than one KLV. that's it, that's the note. she prints one and only one, so if your buffer is being extra and holding a whole squad of KLVs, that's lowkey a you problem and you gotta loop or something, iykyk 😭

no cap, don't assume one KLV per buffer just because this function exists. the buffer can absolutely contain more than one. read the room (and the buffer) fr fr 💀
