vmw_query_readback_all(9)

okay so bestie, this is vmw_query_readback_all(9) from the Kernel API Manual, and she’s literally here to handle cached query states 💖✨

🎀 NAME 🎀

vmw_query_readback_all — read back cached query states 🦋

✨ SYNOPSIS ✨

int vmw_query_readback_all (struct vmw_bo *dx_query_mob );

🫶 ARGUMENTS 🫶

• dx_query_mob — the buffer containing the DX query MOB 🎀

💅 DESCRIPTION 💅

okay so the whole vibe: this reads back the cached states from the device if they exist ✨. It’s giving “go get the cached stuff,” but make it kernel.

⚠️ heads up bestie: this function assumes binding_mutex is held. That’s not optional garnish, that’s the assumption. 💀
