💫 msm_dp_link_...ttern_params(9) 💫

okay so bestie, welcome to the Kernel API Manual — section 9 of the manual, no less — and today's main character is msm_dp_link_parse_video_pattern_params. yes the page header is truncated with ... in the middle, no that's not a typo, that's just how she's listed. we move. 🎀

---

✨ NAME ✨

msm_dp_link_parse_video_pattern_params — parses video pattern parameters from DPCD 💅

like, she goes into the DPCD and pulls out the video pattern params. that's the whole job. lowkey iconic.

---

🦋 SYNOPSIS 🦋

int msm_dp_link_parse_video_pattern_params (struct msm_dp_link_private
*link );

---

🌸 ARGUMENTS 🌸

• link — Display Port Driver data. that's the whole argument. one (1) argument. she's low maintenance like that 🫶

---

💖 DESCRIPTION 💖

Returns 0 if it successfully parses the video link pattern and the link bit depth requested by the sink and, and if the values parsed are valid.

okay yes, "and, and" — that's literally how the original says it, I'm not doing a bits-and-bytes edit on the source text, that's not my job. 😭

so fr fr: success = 0. and success happens when she parses the video link pattern and the link bit depth requested by the sink, and those parsed values are valid. three things. all three. no shortcuts. periodt. 🔥
