xe_bo_has_valid_ccs_bb(9)

💖 NAME 💖

Hiii bestie, welcome to the Kernel API Manual page for xe_bo_has_valid_ccs_bb(9) — the little check for whether CCS's BBs were setup for the BO. ✨

✨ SYNOPSIS ✨

bool xe_bo_has_valid_ccs_bb (struct xe_bo *bo );

🎀 ARGUMENTS 🎀

• bo — the xe_bo to check. That's the whole vibe-check target, bestie. 🎯

🦋 DESCRIPTION 🦋

Okay so here's the tea: the CCS's BBs should only be setup by the driver VF, but it is safe to call this function also by non-VF driver. No cap — safe is safe. 🫶

💜 RETURN 💜

It returns true iff the CCS's BBs are setup, and false otherwise. Literally a yes/no moment. 💅
