💅 pm8001_ctl_sas_spec_support_show(9) — the kernel API manual, bestie edition ✨

okay so this is a page straight out of the kernel API manual, and it's about one specific little sysfs show function. yes it's niche. no we're not skipping it. it's giving "small but mighty" energy and honestly? iconic. 🎀

🌸 NAME 🌸

pm8001_ctl_sas_spec_support_show — this one answers the question "is SAS spec supported?" like the little yes/no king it is 👑

✨ SYNOPSIS ✨

ssize_t pm8001_ctl_sas_spec_support_show (struct device *cdev ,
                                          struct device_attribute *attr ,
                                          char *buf );

that's the whole signature, no cap. it takes three things and hands you back a ssize_t. periodt. 💅

🫶 ARGUMENTS 🫶

  • cdev — pointer to the embedded class device 🧚 — like, it's the device hangin' out inside there
  • attr — the device attribute (unused) 🙈 — yes bestie it's literally marked unused, so don't stress about it
  • buf — the buffer returned 💖 — this is where the answer goes, this is the moment the buffer has been waiting for

🦋 DESCRIPTION 🦋

so. it's a sysfs 'read-only' shost attribute. that's it, that's the whole vibe check — read-only, shost-level, sysfs attribute. lowkey simple, highkey important. 🔥

🌈 SEE ALSO 🌈

okay this list is LONG and it ATE, so buckle up bestie — here's every single sibling function and reference, fr fr:

like I said. twenty-five entries. every last one of them 💀💜

ngl bestie, if you were looking for a big dramatic page you came to the wrong place — this function is three args and one line of description. and yet? still slay. 🍓

and that's a wrap, mwah 💋 — this page lives in ./drivers/scsi/pm8001, it's the October 2026 edition, and it's filed under pm8001_ctl_s...support_show(9). go forth and read your sysfs attributes, my love 🫶✨
