How to mesure current SPI transfer speed

["Kevyn-Alexandre Paré" <kapare-7qmld2CjetYf4mhTGKTGE9BPR1lH4CV8@public.gmane.org>]

Hi,

What's the best way to calculate the current SPI transfer speed?

Right now I use something like that and transfer one spi_message with 1
spi_transfer of 100000 bytes and I do the math... I know that this is
not accurate and was wondering if anyone have a better way?


struct timeval tv_before;
struct timeval tv_after;

do_gettimeofday(&tv_before);
    status = spi_sync(spike_dev.spi_device, &spike_ctl.msg);
do_gettimeofday(&tv_after);
    long elapsedTime = (tv_after.tv_usec - tv_before.tv_usec);


Thx
