cxl_rp_gather_bandwidth(9)

💅 NAME 💅

okay so welcome to the Kernel API Manual, bestie — this page is cxl_rp_gather_bandwidth(9), and it is literally here to handle the root port level bandwidth collection. That’s the whole vibe: root port, bandwidth, collection, slay. 🎀

✨ SYNOPSIS ✨

struct xarray * cxl_rp_gather_bandwidth (struct xarray *xa );

🎀 ARGUMENTS 🎀

• xa — the xarray that holds the cxl_perf_ctx that has the bandwidth calculated below each root port device. So like, xa is the container, and inside it is the cxl_perf_ctx with the bandwidth calculated below each root port device. iykyk 🦋

🦋 RETURN 🦋

you get back the xarray that holds cxl_perf_ctx per host bridge — or ERR_PTR(-errno) for the error case. no cap, that’s the return situation. 💅
