mipi_dsi_co...de_ext_multi(9)

📦 version 7.3.1, in nixpkgs unstable

mipi_dsi_co...de_ext_multi(9) 💖 straight outta the Kernel API Manual, bestie — pull up a chair, we're doing DSI compression today and honestly? it's giving main character energy.

✨ NAME ✨

mipi_dsi_compression_mode_ext_multi — enable/disable DSC on the peripheral 🎀

(yeah that's Display Stream Compression, the glow-up your panel gets when it's trying to look cute without eating all the bandwidth, iykyk)

🌸 SYNOPSIS 🌸

void mipi_dsi_compression_mode_ext_multi (struct mipi_dsi_multi_context
*ctx , bool enable , enum mipi_dsi_compression_algo algo , unsigned int
pps_selector );

no cap, that's the whole signature. returns absolutely nothing (void) — it's a "just do it" kind of function, not a "let me think about it and report back" kind of function 💅

🦋 ARGUMENTS 🦋

  • ctx — the context for multiple DSI transactions. literally the group chat where all your calls get tracked 🫶
  • enable — whether to enable or disable the DSC. true = on and iconic, false = off and napping 😴
  • algo — the selected compression algorithm. yes it's enum mipi_dsi_compression_algo, no I will not be choosing it for you ✨
  • pps_selector — picks which PPS you want out of the table of pre-stored or uploaded PPS entries. it's like picking a fit from your closet, except the closet is a table and the fits are Picture Parameter Sets 👑

💜 DESCRIPTION 💜

Okay so picture mipi_dsi_compression_mode_ext — the regular one — and now picture its more chill sibling. This one is like mipi_dsi_compression_mode_ext, except it deals with errors in a way that makes it convenient to make several calls in a row 🔥

That's the entire glow-up. No drama, no if ladder in your driver, just call it again and again and let the multi-context handle the mess. periodt 💅

ngl the "deals with errors in a way that makes it convenient to make several calls in a row" part is the WHOLE point. that's the assignment. that's why _multi is in the name, bestie 🧚

🌈 SEE ALSO 🌈

the whole squad, fr fr — every single one of these showed up to the party 🎉 and yes, the kernel file is ./drivers/gpu/drm/drm_mipi_dsi.c:

like I said. the whole squad. ate and left no crumbs 🍓

okay that's the page!! the crumbs say it lives in ./drivers/gpu/drm and it's stamped October 2026 🌸 go forth, enable that compression, and remember: several calls in a row is literally the vibe 💜✨🎀
