📦 version 7.3.1, in nixpkgs unstable

💅 mipi_dsi_dcs_read_multi — the Kernel API Manual, bestie edition ✨

okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, that's the manual name, we're being ✨official✨) and it's about mipi_dsi_dcs_read_multi. She's giving "the multi version of a read function, but make it error-friendly" and honestly? iconic. 🎀

🌸 NAME 🌸

mipi_dsi_dcs_read_multi — literally just mipi_dsi_dcs_read() with accum_err energy. that's the whole vibe. 💖

✨ SYNOPSIS ✨

void mipi_dsi_dcs_read_multi (struct mipi_dsi_multi_context *ctx , u8
cmd , void *data , size_t len );

like, she takes four things and returns void. no cap, that's it. 🫶

🦋 ARGUMENTS 🦋

  • ctx — the context for multiple DSI transactions. this is the girl holding the receipts for the whole run, so all your back-to-back calls stay coordinated. 👑
  • cmd — the DCS command. the actual thing you're asking the display to do. 💅
  • data — buffer in which to receive data. this is where the tea gets poured. 🍓
  • len — size of the receive buffer. please get this right or the data will simply not fit and that's on you. 😭

🔥 DESCRIPTION 🔥

so, like, she's like mipi_dsi_dcs_read — same general idea, same energy — but she deals with errors in a way that makes it convenient to make several calls in a row. 🧚

that's the whole main character move: you're not doing one lonely read, you're doing a stack of them, and she handles the errors so you don't have to stop and check after every single one. highkey convenient. ⭐

🌈 SEE ALSO 🌈

okay buckle up bestie, the guest list is LONG. all of these are in Kernel file ./drivers/gpu/drm/drm_mipi_dsi.c and all of them are (9) pages, iykyk:

like, that's the whole friend group. go say hi. 🫶💜

and that's the page!! 🎀 she lives in ./drivers/gpu/drm and this printing is dated October 2026 — so yeah, future girl summer. mwah, love u, read ur multi funcs safely 💖✨🌸
