Re: [PATCH/RFC] SPI: add DMAUNSAFE analog to David Brownell's core

What is the speed of your SPI bus?

And what are your preformance requirements?

The maximum frequency for the SPI bus is 26 MHz, WLAN driver is to work at true 10 Mbit/sec.

P. S. I'm speaking not about this particular case during most part of this conversation. Sound cards behind the SPI bus will suffer a lot more since it's their path to use wXrY functions (lotsa small transfers) rather than WLAN's.
