thc_dma_release(9)

💅 thc_dma_release(9) — from the Kernel API Manual, bestie

okay so listen, this is a page straight out of the Kernel API Manual (that's the manual name, we're not being mysterious about it) and it's about thc_dma_release — literally the function that frees the DMA buffers for all the DMA engines. all of them. every single one. no stragglers. 💖

✨ NAME ✨

thc_dma_release — release DMA buffers for all DMA engines 🫶

like, the whole cleanup era. it's giving end-of-the-movie montage where everybody packs their bags and goes home.

---

🌸 SYNOPSIS 🌸

void thc_dma_release (struct thc_device *dev );

that's it. that's the whole signature. returns nothing (void), takes one (1) argument, and it is not here to play games. ⭐

---

🎀 ARGUMENTS 🎀

• dev — the pointer to the THC private device context. yes, that device context. the one you already have. hand it over and let the function do its thing. 🦋

ngl if you're passing something that isn't a valid THC private device context, that's on you — the page just says it's the pointer of the THC private device context, and we're taking that at face value. 💀

🔥 SEE ALSO 🔥

the whole friend group, honestly. go read these next:

• Kernel file ./drivers/hid/intel-thc-hid/intel-thc/intel-thc-dma.c 👑

• thc_dma_allocate(9)

• thc_dma_unconfigure(9)
• thc_rxdma_reset(9)
• thc_rxdma_read(9)
• thc_swdma_read(9)
• thc_dma_write(9)

like, allocate it, configure it, unconfigure it, reset it, read it, write it, and — iconically — release it. the full lifecycle ate and left no crumbs. 🌈

and that's the page!! mwah 💋 this little icon was living in ./drivers/hid/intel-thc-hid/in... and dated October 2026, so yeah, she's from the future and she's still relevant. periodt. 🧚💜
