Hi,
We are testing Wi-Fi throughput and CPU loading on AM1808, and we runing Wi-Fi 11g mode(throughput is arround 21Mbps actually), the SW irq occupied 28% CPU time.
Mem: 7956K used, 52968K free, 0K shrd, 1268K buff, 2276K cached
CPU: 0% usr 44% sys 0% nic 14% idle 0% io 11% irq 28% sirq
In addition, we also check SDIO host driver, the DMA seems already enabled.
Do we have another way to ensure the SDIO DMA setting is corrected in our case? (through the register or ....)
