mipi_dsi_dua...buffer_multi(9)

🎀 NAME 🎀

mipi_dsi_dual_dcs_write_buffer_multi — literally mipi_dsi_dcs_write_buffer_multi() for two dsi channels, one after the other. Welcome to the Kernel API Manual, bestie; this one is lowkey niche but highkey useful. 💅

✨ SYNOPSIS ✨

okay so the signature is giving “two screens, one function” and here it is exactly:

void mipi_dsi_dual_dcs_write_buffer_multi (struct mipi_dsi_multi_context
*ctx , struct mipi_dsi_device *dsi1 , struct mipi_dsi_device *dsi2 ,
const void *data , size_t len );

🫶 ARGUMENTS 🫶

• ctx — Context for multiple DSI transactions. This is the group-chat context, basically.
• dsi1 — First dsi channel to write buffer to. Channel one, bestie.
• dsi2 — Second dsi channel to write buffer to. Channel two, right after.
• data — Buffer containing data to be transmitted. The actual content being sent.
• len — Size of transmission buffer. How much data we’re working with.

💖 DESCRIPTION 💖

It’s a wrapper around mipi_dsi_dcs_write_buffer_multi that lets you conveniently write to two dsi channels, one after the other. That’s the whole plot, no cap. ✨

That’s the tea 🫶✨ — source/version is ./drivers/gpu/drm, dated October 2026, and the footer tag is mipi_dsi_dua...buffer_multi(9). Go forth and write to both channels, bestie. 💅🌸
