thc_dma_set_...packet_sizes(9)

✨ NAME ✨

thc_dma_set_max_packet_sizes — Set max packet sizes for all DMA engines 💅

okay bestie, you're looking at the Kernel API Manual page for thc_dma_set_...packet_sizes(9), and it's literally giving “one function, all the DMA packet sizes.” No cap. 🫶

🎀 SYNOPSIS 🎀

int thc_dma_set_max_packet_sizes (struct thc_device *dev , size_t
       mps_read1 , size_t mps_read2 , size_t mps_write , size_t mps_swdma );

💖 ARGUMENTS 💖

• dev — the pointer to the THC private device context. literally what it sounds like, bestie.
• mps_read1 — RxDMA1 max packet size.
• mps_read2 — RxDMA2 max packet size.
• mps_write — TxDMA max packet size.
• mps_swdma — Software DMA max packet size.

🦋 DESCRIPTION 🦋

okay so here's the whole vibe: if mps is not 0, that means the corresponding DMA channel is used. then it sets the flag to turn on this channel. slay. ✨

🌸 RETURN 🌸

0 on success, other error codes on failed. yes bestie, “on failed” is the wording — we keep the facts exactly, always. 😭
