💅 qcom_tzmem_alloc(9) — from the Kernel API Manual, bestie ✨

okay so this is a page about qcom_tzmem_alloc, and it lives in the Kernel API Manual — yes, the whole manual, and yes, this function is THAT girl 🎀

🌸 NAME 🌸

qcom_tzmem_alloc — allocate a memory chunk that's suitable for sharing with TZ 🫶

like, it grabs you some memory, but specifically the kind that TZ will accept. no cap.

⭐ SYNOPSIS ⭐

void * qcom_tzmem_alloc (struct qcom_tzmem_pool *pool , size_t size ,
       gfp_t gfp );

look at her go 💅 three args, no drama.

🦋 ARGUMENTS 🦋

  • pool — the TZ memory pool you're pulling from. this is where the memory comes from, bestie 🌈
  • size — how many bytes you want. the exact number. don't be weird about it 💜
  • gfp — the GFP flags. yes, those. 👑

✨ DESCRIPTION ✨

So here's the tea: you can use this in any context. literally any. it's giving versatile, it's giving low-maintenance, it's giving main character energy 🔥

🎀 RETURN 🎀

You get back the address of the allocated buffer — iconic, love that for you 💖

OR you get NULL if no more memory can be allocated 😭 it's not you, it's the allocator.

⚠️ important, bestie: that buffer must be released using qcom_tzmem_free. no ghosting your memory. free it, periodt 🫶
