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

okay so this is a page from the Kernel API Manual and it's about _transport_phy_enable, a lil function that turns phys on and off. yes. phys. plural. we love that for us 🦋

✨ NAME ✨

_transport_phy_enable — enable/disable phys

🌸 SYNOPSIS 🌸

int _transport_phy_enable (struct sas_phy *phy , int enable );

🎀 ARGUMENTS 🎀

• phy — the sas_phy object. that's your phy. your guy. your main character 🫶
• enable — enables the phy when true. that's it, that's the whole vibe check.

💖 DESCRIPTION 💖

so like, lowkey there's a catch: this only supports sas_host direct attached phys. that's the whole description, no cap. if you were hoping for expander energy, nope, not here 🙈

⭐ RETURN ⭐

• 0 for success 💫
• non-zero for failure 😭

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/scsi/mpt3sas/mpt3sas_transport.c — go read it, iykyk 👑
