💖 scsi_device_supports_vpd(9) 💖

okay so this page is from the Kernel API Manual, and it's basically a vibe check for SCSI devices: does this device support VPD pages or not? let's get into it, bestie 🦋

🌸 NAME 🌸

scsi_device_supports_vpd — test if a device supports VPD pages ✨

💅 SYNOPSIS 💅

int scsi_device_supports_vpd (struct scsi_device *sdev );

🎀 ARGUMENTS 🎀

• sdev — the struct scsi_device to test 🫶

🔥 DESCRIPTION 🔥

so here's the tea: if the try_vpd_pages flag is set, it takes precedence — periodt. otherwise, we assume VPD pages are supported if the SCSI level is at least SPC-3 and skip_vpd_pages is not set. that's the whole rule, no cap 💀

🌈 SEE ALSO 🌈

• Kernel file ./include/scsi/scsi_device.h struct scsi_vpd(9) — yes bestie, go peek at the header 👑
• shost_for_each_device(9)
• __shost_for_each_device(9)
• scsi_device_is_pseudo_dev(9)

🎀 that's a wrap, bestie — source/version ./include/scsi, dated October 2026, and this iconic page is scsi_device_supports_vpd(9). byeee 💖
