xe_guc_ct_in...ost_hwconfig(9)

💅 NAME 💅

okay so this is the xe_guc_ct_init_post_hwconfig(9) page from the Kernel API Manual, bestie. the function is literally xe_guc_ct_init_post_hwconfig, and its whole vibe is “Reinitialize the GuC CTB in VRAM.” no cap. 🦋

✨ SYNOPSIS ✨

int xe_guc_ct_init_post_hwconfig (struct xe_guc_ct *ct );

🫶 ARGUMENTS 🫶

• ct — the xe_guc_ct. that’s the main-character struct being passed in, periodt 💅

🌸 DESCRIPTION 🌸

so what it does is allocate a brand-new BO in VRAM, and free the previous BO that was allocated in system memory (SMEM). that’s the whole glow-up: VRAM BO in, SMEM BO out. ✨

heads up bestie: this is applicable only for DGFX products. not everything gets this treatment, iykyk 🫶

💖 RETURN 💖

• 0 on success — slay, it worked 🎀
• a negative errno on failure — not the vibe, but at least you know 😭
