✨ iwl_acpi_get_mcc(9) ✨

okay so this is a page from the Kernel API Manual bestie, and we're about to get into it πŸ’… it's giving "wireless driver lore" and honestly? kind of iconic.


🌸 NAME 🌸

iwl_acpi_get_mcc β€” literally reads the MCC from ACPI, but only if it's actually there 🫢


⭐ SYNOPSIS ⭐

int iwl_acpi_get_mcc (struct iwl_fw_runtime *fwrt , char *mcc );

πŸŽ€ ARGUMENTS πŸŽ€

  • fwrt β€” the fw runtime struct, aka the whole vibe context this function works with πŸ’–
  • mcc β€” the output buffer, and it's exactly 3 bytes, which will get the MCC dropped into it πŸ“

πŸ¦‹ DESCRIPTION πŸ¦‹

so basically this function tries to read the current MCC from ACPI β€” if available. that's the whole assignment. if ACPI's got it, slay, it reads it. no cap, that's it πŸ’€


πŸ”₯ RETURN πŸ”₯

  • 0 on success πŸ‘‘
  • or a negative error code 😭

lowkey a tiny function, highkey important. three bytes of MCC and a dream πŸ’œ
