💅 ib_is_opa_gid(9) — the kernel API manual, but make it cute

okay bestie, welcome to the ib_is_opa_gid page from the Kernel API Manual ✨ this one is short and sweet and honestly kind of an icon in the "tiny helper function" category, so let's get into it 🫶

🌸 NAME 🌸

ib_is_opa_gid — returns true if the top 24 bits of the gid contains the OPA_STL_OUI identifier. Lowkey the whole point? It identifies that the provided gid is a special purpose GID meant to carry extended LID information. like, that's its entire job and it does it slayfully 💅

✨ SYNOPSIS ✨

bool ib_is_opa_gid (const union ib_gid *gid );

🎀 ARGUMENTS 🎀

  • gid — The Global identifier. yep, that's the one, that's the input, hand it over 🍓

🔥 SEE ALSO 🔥
