nx_hcall_sync(9)

💖 nx_hcall_sync(9) 💖

from the Kernel API Manual, bestie — short page, but it still ate. ✨

🌸 NAME 🌸

nx_hcall_sync — make an H_COP_OP hcall for the passed-in op structure. 💅

---

🦋 SYNOPSIS 🦋

int nx_hcall_sync (struct nx_crypto_ctx *nx_ctx , struct vio_pfo_op *op
, u32 may_sleep );

---

🎀 ARGUMENTS 🎀

• nx_ctx — the crypto context handle, bestie. that's the main-character handle. 💖
• op — the PFO operation struct to pass in. literally handing over the op. 🫶
• may_sleep — a flag indicating the request can sleep. yes, that's the whole vibe of this flag. 😴✨

---

💜 DESCRIPTION 💜

okay so it makes the hcall, and it keeps retrying while the hardware is busy. no cap. 🔥

if we cannot yield the thread, it limits the number of retries to 10 right here — yes, 10, not a vibe-based guess. 😭💀
