💖 xilinx_dpdma_chan_err_task(9) 💖

okay bestie, welcome to the Kernel API Manual entry for xilinx_dpdma_chan_err_task — yes, the name is giving "I have 47 tabs open," but we're gonna slay it together 💅

---

✨ NAME ✨

xilinx_dpdma_chan_err_task — Per channel tasklet for error handling 🫶

---

🌸 SYNOPSIS 🌸

the whole signature is literally:

void xilinx_dpdma_chan_err_task (struct tasklet_struct *t );

---

🎀 ARGUMENTS 🎀

• t — a pointer to the tasklet that's associated with this handler. that's the whole vibe check for this one, bestie ✨

---

🦋 DESCRIPTION 🦋

okay so this is the per-channel error-handling tasklet. here's the routine: it waits for the outstanding transaction to complete and then triggers error handling. after error handling is done, it re-enables channel error interrupts, and it restarts the channel if needed 😭💖

no cap, that's the flow. error handling main character energy, periodt.
