mipi_dsi_co...ion_mode_ext(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mipi_dsi_co...ion_mode_ext — NAME

ok so this is mipi_dsi_compression_mode_ext from the Kernel API Manual, and bestie, it's literally the function that turns DSC (Display Stream Compression) on or off on your peripheral. ✨

🌸 SYNOPSIS

int mipi_dsi_compression_mode_ext (struct mipi_dsi_device *dsi , bool
enable , enum mipi_dsi_compression_algo algo , unsigned int pps_selector
);

🎀 ARGUMENTS

  • dsi — the DSI peripheral device itself, your main character 🫶
  • enable — a bool that says whether we're enabling or disabling the DSC. yes or no, on or off, slay or not-slay
  • algo — which compression algorithm you picked (enum mipi_dsi_compression_algo, no cap you gotta choose)
  • pps_selector — picks the PPS out of the table of pre-stored or uploaded PPS entries. like choosing your outfit from the closet, but for pixels 👑

👑 DESCRIPTION

Enables or disables Display Stream Compression on the peripheral. That's the whole vibe. 💖

🚨 WAIT. This function is deprecated. Do not build new stuff on it, bestie, I'm serious. Use mipi_dsi_compression_mode_ext_multi instead — that's the upgraded version, the glow-up, the one with main character energy. This one is giving legacy code. 😭

🌈 RETURN

0 on success, or a negative error code on failure. So like — zero means you ate 💅, anything negative means the vibe check failed and you should go read the error code.

ok that's the whole page, ily, go use the _multi version instead 💜
