Is there any way to measure time using MicroBlaze core in Vitis for Arty A7-100T?

[zzzhhh]

I embedded a MicroBlaze core in the FPGA of Arty A7-100T board. To measure time spent by a piece of code run by MicroBlaze core in Vitis, I tried

#include <time.h>

clock_t start, end;
start=clock();
// code to be measured
end=clock();

But I received error

(.text+0x8): undefined reference to `times'

So, is there any API from Vitis SDK I can use to measure time using MicroBlaze core in Vitis for Arty A7-100T? If answer is no, is that because of the limitation of MicroBlaze? If so, if I replace MicroBlaze with some other processor core, say RISC-V, can I measure time in Vitis? Or, is there no hope at all to do time measurement using C code in Vitis on top of Artix-7 FPGA?

So "time.h" doesn't work on zynq and microblaze processors as far as I know. There is a xilinx specific library called "xtime_l.h" that implements time measurement functions.

Microblaze doesn't have a built-in counter by default - it implements sleep functions in software, using instructions with known durations, for example. You could use an AXI Timer/Counter and the xtmrctr driver.

xtime_l looks to be a Zynq-7000-specific driver and uses the built-in hardware timer featured by the A9 processor, I don't know why it might be showing up in a Microblaze BSP.

Thanks,
