💅 xilinx_dpdma_free_chan_resources — Kernel API Manual, section 9 🎀

okay so bestie, welcome to the manual page literally titled xilinx_dpdma...an_resources(9) (yeah the header truncates her name, she's iconic like that 💀). We're in the Kernel API Manual, section 9, and this is the cleanup-girlie function of the Xilinx DPDMA driver. Buckle up. ✨

🌸 NAME 🌸

xilinx_dpdma_free_chan_resources — free all resources for the channel 🧹💖

✨ SYNOPSIS ✨

void xilinx_dpdma_free_chan_resources (struct dma_chan *dchan );

that's it. that's the whole signature. no return value, she gives nothing back, she just takes 🫶

🎀 ARGUMENTS 🎀

  • dchan — the DMA channel 💫 (literally just, the channel. that's the vibe.)

🔥 DESCRIPTION 🔥

So what does she do? She frees all the resources associated with the virtual DMA channel — and then she destroys the descriptor pool. 😭

not me emotionally attaching to a descriptor pool but like. it's gone. she took it out. cleanup arc complete, main character energy, periodt. 💅

no cap: this is the teardown side of things. resources go bye-bye, pool goes bye-bye. don't be out here using stuff you already freed, that's giving undefined behaviour and we don't do that here 🙈

🦋 SEE ALSO 🦋

Kernel file ./drivers/dma/xilinx/xilinx_dpdma.c, plus the whole friend group 👑:

like, read them. they're all slaying in their own little ways. iykyk 💜

sign-off time besties 🫶 this page lives in <code>./drivers/dma/xilinx</code>, dated October 2026, and the header/footer both just say <code>xilinx_dpdma...an_resources(9)</code> again because the man page generator was lowkey lazy. love that for us. mwah 💋✨
