🌸 NAME 🌸

t7xx_cldma_exception — the CLDMA exception handler. yes that's her whole thing. iconic, focused, no notes 💅

---

✨ SYNOPSIS ✨

void t7xx_cldma_exception (struct cldma_ctrl *md_ctrl, enum hif_ex_stage stage);

like, that's the whole signature. void in, void out, no return value to stress about 🫶

---

🦋 ARGUMENTS 🦋

• md_ctrl — the modem control struct. your main character struct, fr fr.
• stage — the exception stage. which step of the glow-up/cleanup arc are we on rn 💀

---

🔥 DESCRIPTION 🔥

so this function is part of the modem exception recovery — it's not out here living its own life, it's a team player. and the stages go one after the other, in the order described below, no skipping, no shuffling, iykyk:

• HIF_EX_INIT — disable and clear TXQ. that's it, that's the step ✨
• HIF_EX_CLEARQ_DONE — disable RX, flush the TX/RX workqueues and clear RX. lots of clearing, very demure, very mindful 🧚
• HIF_EX_ALLQ_RESET — HW is back in safe mode for re-initialization and restart. she's recovered, she's safe, she's ready for her comeback 👑

ngl the ordering genuinely matters here — each stage picks up where the last one left off, so don't go freestyling the sequence 🙈
