The driver should deny a too large size if it's unrealistic. But 1MB is realistic for many systems. So, the number depends on the system.
Are there any popular applications that really want a DMA buffer larger than 64KB?
On a side note, I notice that ALSA has some scatter-gather support. If an application uses S/G, I presume the concept of a DMA buffer size doesn't even apply?
