💅 libnvmf_con...e_discovered(9) 💅

okay so bestie, this page is from the libnvme API manual, and it’s lowkey iconic for anyone poking at discovered controllers. ✨

🌸 NAME 🌸

libnvmf_config_resolve_discovered — parameters for a controller that is not in the configuration. no cap, that’s the whole vibe, periodt. 🎀

✨ SYNOPSIS ✨

the signature is literally giving:

const struct libnvmf_params * libnvmf_config_resolve_discovered (const
struct libnvmf_config *config , const struct libnvmf_config_conn *via_dc
, bool is_dc );

🎀 ARGUMENTS 🎀

  • config — the resolved configuration. main character of this whole call, fr fr.
  • via_dc — the DC connection the controller was discovered through, or NULL for a controller with no configured origin (e.g. an mDNS-discovered DC).
  • is_dc — true for a discovered discovery controller (a referral), false for a discovered I/O controller.

🦋 DESCRIPTION 🦋

okay so picture this: a controller learned at runtime — from a discovery log page, an AEN, or mDNS — has no section in the configuration, but still draws parameters from it: the defaults of the file scope it was discovered through, or the top-level scope when it has no configured origin. the four combinations are literally:

  • (via_dc = DC, is_dc = true) — a referral: a DC discovered via a DC; draws that DC's DC-defaults scope
  • (via_dc = DC, is_dc = false) — a DLP-discovered IOC; draws that DC's IOC-defaults scope
  • (via_dc = NULL, is_dc = true) — a DC with no configured origin (e.g. mDNS); draws the top-level DC scope
  • (via_dc = NULL, is_dc = false) — an IOC with no configured origin; draws the top-level IOC scope

💖 RETURN 💖

you get back a borrowed parameter set, valid while config is alive. via_dc must be a connection of config; an I/O-controller via_dc yields NULL. 🫶

bestie, Passing a connection that does not belong to config is undefined — do not do it. 💀

mwah 💋 — this cutie is from the libnvme API manual, dated October 2026, and the footer tag is libnvmf_config_resolve_disclibnvmf_con...e_discovered(9). slay, byeee 🫶
