on SDB,i find the function "do_gettimeofday" can`t get exact time about microsecond ,

i wanna get exact time in driver ,what can i do?

if you wanna say timer or hrtimer,i had try ,use it to get time isn`t good idea,frequent use hrtimer in microsecond could lead system crash.

Hi tab song,

ENET module in IMX6Q supports IEEE 1588 Precision Time Protocol (PTP). You can take a look in chapter 23 of Reference Manual. i.MX6Q Reference Manual
