zynqmp_dp_train_loop(9)

💅 zynqmp_dp_train_loop(9) — the gen-z field guide 💅

okay so bestie, you found a page from the Kernel API Manual and it's about zynqmp_dp_train_loop — a function that literally saves the day by downshifting the link rate when training is being a flop. we're gonna walk through it together, no cap 🫶

---

✨ NAME ✨

zynqmp_dp_train_loop — downshift the link rate during training 🔥

like… when the link just won't cooperate, this is the friend who says "okay bestie, let's try a slower vibe."

---

✨ SYNOPSIS ✨

void zynqmp_dp_train_loop (struct zynqmp_dp *dp );

yep, that's it. one argument, void return, no drama 💅

---

✨ ARGUMENTS ✨

• dp — the DisplayPort IP core structure 🎀 like, this is the whole main character of the operation, the DisplayPort IP core struct itself.

---

✨ DESCRIPTION ✨

so the actual job?? train the link. that's the goal, that's the moment. 🦋

but here's the twist — if training is not successful, it downshifts the link rate and tries again. it's giving "if at first you don't succeed, lower the rate and slay" energy. genuinely iconic problem-solving 😭✨

ngl this is the "we don't give up, we just recalibrate" function and I'm obsessed.
