ALSA really wants to dynamically know the address of the current DMA location while transfers are active. This is an important piece of implementing pause/resume. Pause doesn't work too well if there is 2s of music already queued. The work around is to know the sample rate and use the jiffy count to estimate how far into the buffer DMA has progressed. But that's not as accurate as just asking the DMA hardware.
I poked around in the SRAM data and couldn't find the address. Is it there or can the Bestcomm tasks be modified to leave it somewhere visible? -- Jon Smirl jonsm...@gmail.com _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
