resctrl_get_default_ctrl(9)

okay bestie, welcome to resctrl_get_default_ctrl(9) from the Kernel API Manual 💖 this is a short little page with main character energy: it returns the default control value for a resource, and the argument is the resource whose default control type is queried. that's the whole plot, no cap. ✨

🌸 NAME 🌸

resctrl_get_default_ctrl — returns the default control value for this resource. literally what it says on the tin, bestie 💅

✨ SYNOPSIS ✨

here's the signature, and yes it's giving very specific spacing:

u32 resctrl_get_default_ctrl (struct rdt_resource *r );

🎀 ARGUMENTS 🎀

• r — the resource whose default control type is queried. that's the resource you're asking about, and the function is checking its default control type 🫶
