GSPI and SDIO performance for 8686

[Tim Harvey]

Greetings,

I've seen a lot of activity lately and development of the GSPI interface 
for libertas.  What max throughput have people been able to get with an 
8686 talking over GSPI?

My previous evaluation with an 8686 talking over SDIO (both to an i.MX31 
SDHC on a patched 2.6.22 and to an OMAP3x SDHC on 2.6.28 beagleboard) 
showed a horribly slow max throughput of about 1.4mbps.  Has anyone seen 
better performance in recent libertas/kernel with the OMAP3x SDHC (ie 
talking to the 8686 on an Overo Fire/Air)?

Thanks,

Tim
