qcom_tzmem_pool_new(9)

📦 version 7.3.1, in nixpkgs unstable

✨ qcom_tzmem_pool_new ✨

okay so bestie, we're in the Kernel API Manual today and this one is a kernel function — a real one, from the Qualcomm TrustZone memory corner of the tree 🫶 stay with me, it's actually so good.

💖 NAME 💖

qcom_tzmem_pool_new — literally just creates a new TZ memory pool. that's it, that's the whole job, and it does it iconically 💅

🌸 SYNOPSIS 🌸

struct qcom_tzmem_pool * qcom_tzmem_pool_new (const struct qcom_tzmem_pool_config *config );

so you hand it a config and it gives you back a struct qcom_tzmem_pool *. yes queen, pointer to a pool ✨

🎀 ARGUMENTS 🎀

  • config — the pool configuration. it's a const struct qcom_tzmem_pool_config *, aka the vibe spec for your new pool. tell it what you want and it'll build it 🦋

🧚 DESCRIPTION 🧚

okay so what this does: it creates a new pool of memory suitable for sharing with the TrustZone. that's the whole tea ☕ — you're making a memory pool that's allowed to hang out with TrustZone, which is a whole separate secure world, so like... it's giving main character energy but with security implications, iykyk.

⚠️ big warning bestie, no cap: it must not be used in atomic context. like, do not. that's a hard no. don't try it, don't be cute about it, don't "just this once" it. 🙈

🔥 RETURN 🔥

you get back either:

  • the new memory pool address 💖 (slay, it worked)
  • or ERR_PTR on error 😭 (check it, always check it, IS_ERR() is your bestie)

🌈 SEE ALSO 🌈

okay that's the whole page, you ate that 💅 this one lives under ./drivers/firmware/qcom, it's from October 2026, and it's part of the Kernel API Manual (the version-y footer situation). go forth and pool responsibly, bestie 🍓✨
