Hi, Another question... :)
The Aureal Vortex has Scatter Gather DMA's for each audio channel. But these SG DMA support only max 4 pages. Each page can have a programable size of upto 4 KB. I was studying the ALSA SG scheme and it doesnt seme to fit into the aureal vortex SG buffer scheme, because ALSA, as far as i understood, only allows pages of the kernel PAGE_SIZE size, and allocates as many pages (without cound limit ?) until the buffer size is reached. But the PAGE_SIZE around 0x400 or 0x800, which is rather small. On the Aureal vortex soundcard side i have 4 registers for page base address, and some sort of config regs to configure each page size and the next page for each page. I just dont understand how could i plug this two apparently incompatible things together. Thank you very much.
