💅 NAME 💅

xilinx_dpdma_chan_handle_err — the DPDMA channel error handling era, no cap 🫶

(this lives in the Kernel API Manual, bestie — that's the manual name, and yes we're citing our sources ✨)

🌸 SYNOPSIS 🌸

void xilinx_dpdma_chan_handle_err (struct xilinx_dpdma_chan *chan );

🎀 ARGUMENTS 🎀

  • chan — the DPDMA channel, obviously 💅 that's the one and only thing you're handing over

🦋 DESCRIPTION 🦋

okay so picture this: something goes wrong 😭. This function is the one that gets called whenever any channel error or any global error happens — like, either kind, she handles both, main character energy fr.

What does she actually do tho? Two things, and they're both iconic:

  • she disables the paused channel by errors — yes, the channel that got paused because of the errors, she shuts that vibe down 💀
  • she determines if the current active descriptor can be rescheduled, depending on the descriptor status 👑

that's it, that's the whole function. short queen, but she's doing the work 🌈
