ibmvtpm_crq_send_init(9)

💖 ibmvtpm_crq_send_init — bestie, it's an intro 💖

okay so real talk, we're in the kernel API manual (section 9, the big-brain zone) and today's main character is ibmvtpm_crq_send_init(9). this is literally the function that sends a CRQ initialize message. that's it, that's the whole vibe. she walks in, she says hi to the CRQ, she leaves. icon behavior. ✨

---

🌸 SYNOPSIS 🌸

int ibmvtpm_crq_send_init (struct ibmvtpm_dev *ibmvtpm );

like, that's her whole signature. takes one thing, returns an int. no drama, no cap. 💅

---

🦋 ARGUMENTS 🦋

• ibmvtpm — the vtpm device struct 🎀 this is the one and only thing you're handing her. she's not asking for more. she's lowkey low maintenance.

---

⭐ RETURN ⭐

• 0 on success 🫶 yay, slay, we ate
• Non-zero on failure 😭 so like, if you get anything that isn't 0, something went sideways and you should probably pay attention

fr fr reminder: 0 means slay, anything else means go read the code, bestie. don't guess. iykyk.

and that's a wrap, bestie 🎀 this page was served fresh from ./drivers/char/tpm, October 2026, in the ibmvtpm_crq_send_init(9) chapter of the Kernel API Manual. go forth and initialize those CRQs. periodt. 👑🌈
