Hello, Sorry.. I am not getting what you are trying to say...What do you mean by reference counter here.?? I am a software person... I am using the Coyote IXP425 platform from ADI..!!.. I tried to read the OSTS register to get the number of clock ticks.From kernel space i could do it. but from user space i couldnt ..i am getting compilation errors when i try to include asm/hardware.h from user space. Is there anyway out?
