25 | * | ||
26 | * To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai | ||
27 | * available in the Alsa doc section on the website | ||
28 | * | ||
29 | * A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100. | ||
30 | * We are using SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated | ||
31 | * by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it. | ||
32 | * So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the | ||
33 | * transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which | ||
34 | * is a mem loc that always decodes to 0's w/ no off chip access. | ||
35 | * | ||
36 | * Some alsa terminology: | ||
37 | * frame => num_channels * sample_size e.g stereo 16 bit is 2 * 16 = 32 bytes | ||
38 | * period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte | ||
39 | * buffer and 4 periods in the runtime structure this means we'll get an int every 256 | ||
40 | * bytes or 4 times per buffer. | ||
41 | * A number of the sizes are in frames rather than bytes, use frames_to_bytes and | ||
42 | * bytes_to_frames to convert. The easiest way to tell the units is to look at the | ||
43 | * type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t | ||
44 | * | ||
45 | * Notes about the pointer fxn: | ||
46 | * The pointer fxn needs to return the offset into the dma buffer in frames. | ||
47 | * Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts. | ||
48 | * | ||
49 | * Notes about pause/resume | ||
50 | * Implementing this would be complicated so it's skipped. The problem case is: | ||
51 | * A full duplex connection is going, then play is paused. At this point you need to start xmitting | ||
52 | * 0's to keep the record active which means you cant just freeze the dma and resume it later you'd | ||
53 | * need to save off the dma info, and restore it properly on a resume. Yeach! | ||
54 | * | ||
55 | * Notes about transfer methods: | ||
56 | * The async write calls fail. I probably need to implement something else to support them? | ||
