dml21_init(9)

✨ NAME ✨

dml21_init — initialize a DML21 context, bestie 💅

This little icon is from the Kernel API Manual, section 9, and it's here to get your DML21 context set up.

---

🌸 SYNOPSIS 🌸

void dml21_init (const struct dc *in_dc , struct dml2_context *dml_ctx ,
const struct dml2_configuration_options *config );

---

🎀 ARGUMENTS 🎀

• in_dc — the dc. That's literally what the manpage says, and honestly? We respect the brevity. 🫶
• dml_ctx — the DML21 context you want to initialize. This is the main character right here. 👑
• config — the dml21 configuration options. All the settings, all the vibes. ✨

---

💖 DESCRIPTION 💖

This function performs initialization that requires the FPU. Yep, it's giving "I need the floating-point unit for this," so you must call it with FPU protection. That is not a suggestion, bestie — it's a requirement. 🔥

No cap: FPU protection is mandatory here. Do not skip it, do not pass go, do not collect $200. 😭
