Subject: emu10k1x/AudigyLS period table
Date: Mon, 28 Jun 2004 22:49:43 -0400 [thread overview]
Message-ID: <1e6ff561e6a898.1e6a8981e6ff56@southeast.rr.com> (raw)
This the information that James Courtier-Dutton found about the AudigyLS that also works for the emu10k1x:
#define PLAYBACK_LIST_ADDR 0x00 /* Base DMA address of a list of pointers to each period/size */
/* One list entry: 4 bytes for DMA address,
* 4 bytes for period_size << 16.
* One list entry is 8 bytes long.
* One list entry for each period in the buffer.
*/
#define PLAYBACK_LIST_SIZE 0x01 /* Size of list in bytes << 16. E.g. 8 periods -> 0x00380000 */
#define PLAYBACK_LIST_PTR 0x02 /* Pointer to the current period being played */
Is this in anyway similar to the emu10k1 PTB scatter-gather? Just wondering if they reused the design.
