asd_ms_get_phy_params(9)

💖 asd_ms_get_phy_params(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the page for asd_ms_get_phy_params(9), and it is literally all about getting phy parameters from the manufacturing sector. ✨

---

🌸 NAME 🌸

asd_ms_get_phy_params — get phy parameters from the manufacturing sector 🎀

---

✨ SYNOPSIS ✨

int asd_ms_get_phy_params (struct asd_ha_struct *asd_ha , struct
asd_manuf_sec *manuf_sec );

---

🎀 ARGUMENTS 🎀

• asd_ha — pointer to the host adapter structure, bestie 🫶
• manuf_sec — pointer to the manufacturing sector ✨

---

🦋 DESCRIPTION 🦋

The manufacturing sector also contains the linked list of sub-segments — because when it was read, its size was taken from the flash directory, not from the structure size. no cap, that detail matters 💅

Okay so here’s the phy situation, and it’s giving very specific rules:

• HIDDEN phys do not count in the total count.
• REPORTED phys cannot be enabled, but they are reported and counted towards the total.
• ENABLED phys are enabled by default and count towards the total.

The absolute total phy number is ASD_MAX_PHYS. hw_prof->num_phys merely specifies the number of phys the host adapter decided to report. 👑

E.g., it is possible for phys 0, 1 and 2 to be HIDDEN, phys 3, 4 and 5 to be REPORTED, and phys 6 and 7 to be ENABLED. In this case ASD_MAX_PHYS is 8, hw_prof->num_phys is 5, and only 2 are actually enabled (enabled by default, max number of phys enableable in this case). 😭🔥
