    Access to the clock register on GPU


      I need to do some granular profiling of huge kernels. Nvidia provides an access to its clock register via inline assembler:

      uint clock_time()
      uint clock_time;
      asm("mov.u32 %0, %%clock;" : "=r"(clock_time));
      return clock_time;


      Is there a similar  possibility to get the current time/clock within the kernel on AMD/ATI GPUs?
