🦋 DESCRIPTION 🦋

This is the helper function that creates a sysctrl command to be sent via xe_sysctrl_send_command. It's giving "prep the command so the send-side bestie can do its thing." The return type is void, so there's literally no return value to obsess over. 🫶

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpu/drm/xe/xe_sysctrl_mailbox.c — go read the source, bestie. 📖
• xe_sysctrl_send_command(9) — the send-side bestie. 💖

💅 that's the whole page, periodt. This rewrite is serving the xe_sysctrl_create_command(9) manual page from the ./drivers/gpu/drm/xe source/version corner of the kernel, dated October 2026, and it lives in the Kernel API Manual. Mwah. 🎀
