I'm using a Linux machine. I am trying to set latency timer value of my Intel PCI card using following command

sudo setpci -d '8086:0100' latency_timer=01

But when I read the value of this register back it is unchanged and shows previous value. I am using following command to display value of the register

sudo setpci -d '8086:0100' latency_timer

Can anybody tell why I'm unable to change value of latency timer?
