ibm_get_table_from_acpi(9)

💖 NAME 💖

ibm_get_table_from_acpi — reads the APLS buffer from ACPI 🦋💅

This is the Kernel API Manual page for ibm_get_table_from_acpi(9), and it’s lowkey iconic.

---

✨ SYNOPSIS ✨

int ibm_get_table_from_acpi (char **bufp );

---

🎀 ARGUMENTS 🎀

• bufp — the address of the pointer where the table gets allocated 💖 so the address can get passed back to you.

---

🌸 DESCRIPTION 🌸

Okay so this method reads the APLS buffer in from ACPI, stores the “stripped” table into a single buffer that it allocates, and passes the address back in bufp. Literally one buffer, one address, no cap 💅✨.

If NULL is passed in as the buffer, this method only calculates the size of the table and returns that without filling in the buffer. It’s giving “just tell me how big it is” energy 🫶.

Returns < 0 on error or the size of the table on success. Periodt 😭👑
