alloc_session(9)

💅 alloc_session(9) — Allocate a session structure ✨

Okay bestie, welcome to the Kernel API Manual page for alloc_session(9) — we're getting into session-structure allocation and it's gonna be cute and precise. 🫶

🌸 NAME

alloc_session — allocate a session structure. That's the whole name, and honestly? Iconic. 💅

✨ SYNOPSIS

struct amdtee_session * alloc_session (struct amdtee_context_data
       *ctxdata , u32 session );

🎀 ARGUMENTS

• ctxdata — the TEE Context data structure. It's the context info coming through, bestie. 💖
• session — the Session ID for which struct amdtee_session structure is to be allocated. Literally the ID that tells us which session structure we're allocating. 🦋

🔥 DESCRIPTION

It scans the TEE context's session list to check if the TA is already loaded into TEE. If yes, it returns the session structure for that TA. If not, it allocates and initializes a new session structure and adds it to the context's session list. No cap. 🌈

⚠️ The caller must hold a mutex. Not optional, bestie — lock it before you call this. 🔒

💀 RETURN

Hmm, this section is completely blank on the original page — no return value is documented here. So there's literally no return info to spill. 🙈

🌈 SEE ALSO

• Kernel file ./drivers/tee/amdtee/core.c — go look at the source for the full lore. 👑

Sign-off time, bestie: this little gem lives under ./drivers/tee/amdtee, is dated October 2026, and its footer name is alloc_session(9). Mwah. 💋✨
