This was interesting implementing. Our generic QueryPerformanceCounter function on ARMv7 was so slow that profiling a block was impossible. I waited about five minutes and I couldn't even get a single frame to output. This instead uses ARMv7's PMU to get cycle counts, which are a relatively minor performance drop in my testing. One disadvantage of this method is that the kernel can lock us out of using these co-processor registers, but it seems to work on my Jetson board. Another disadvantage is that we aren't having block times in "real" time but cycles instead, not too big of a deal. This also removes instruction run counts from profiling because that's just annoying and we don't expose an interface for even getting those results from our UI. |
