🎀 mei_dma_ring_read(9) 🎀

okay bestie, welcome to the Kernel API Manual corner of the group chat. This one is short and sweet: mei_dma_ring_read is here to read data from the ring. That’s the whole assignment. 💅

✨ NAME ✨

mei_dma_ring_read — read data from the ring. periodt. 🫶

🌸 SYNOPSIS 🌸

void mei_dma_ring_read (struct mei_device *dev , unsigned char *buf , u32 len );

🦋 ARGUMENTS 🦋

• dev — the mei device. main character struct energy. 👑
• buf — buffer to read into: may be NULL in case of dropping the data. so if you’re literally dropping it, NULL is allowed, no cap. 🙈
• len — length to read. bestie, that’s the length. 💖
