📦 version 7.3.1, in nixpkgs unstable

💅 pmcraid_show_adapter_id — the kernel API manual, bestie edition

okay so this is page pmcraid_show_adapter_id(9) and it lives in the Kernel API Manual section nine, which is literally the "kernel internals, don't touch unless you know what you're doing" shelf. it's giving "one tiny sysfs show function" energy and honestly? iconic. 🎀

✨ NAME ✨

pmcraid_show_adapter_id — displays the adapter id that the driver assigned, no cap 🦋

🫶 SYNOPSIS 🫶

ssize_t pmcraid_show_adapter_id (struct device *dev , struct device_attribute *attr , char *buf );

like, that's the whole signature. three args, one return, zero drama. 💜

🌸 ARGUMENTS 🌸

  • dev — the class device struct, aka the star of the show, the main character 👑
  • attr — unused. yeah. it's there because the callback contract said so. we don't touch it, we don't judge it 🙈
  • buf — the buffer, the little stage where the output goes ✨

💖 DESCRIPTION 💖

Return value: the number of bytes printed to the buffer. that's it, that's the whole description, and honestly the brevity is highkey slay. 🧚

it prints the adapter id the driver assigned, into buf, and hands you back the byte count. periodt. 💅

heads up bestie: attr is literally unused here, so if you're out here expecting it to do something — it does not. it's decorative. a little accessory. 🎀

🔥 SEE ALSO 🔥

so the source of all this is the kernel file ./drivers/scsi/pmcraid.c, and then there's a whole friend group of related functions, all section nine. buckle up, this list is long but we are NOT skipping anybody, every one of them gets their moment:

like… the whole driver said "we're all in this together" and honestly 🫶. iykyk. 🌈

and that's the page!! it's from the source tree at ./drivers/scsi, dated October 2026, and it's filed under pmcraid_show_adapter_id(9) in the Kernel API Manual — mwah, go read the rest of the pmcraid saga, ily, bye bestie 💖🎀🦋💅
