Hi all, i am running some RT tests on imx8qxp. Kernel is a imx (nxp) modified kernel, but with rt patch (5.4.70) that at least applies properly. Linux version 5.4.70-rt40-00120-g3e7dde1168e5-dirty I am running some histograms by cyclictest --duration=180 -t=1 -m -Sp99 \ -i2000 -h3000 -q > histogram Average is near 16uS but there are some outside values near 40000, as 000009 000000 000000 000000 000000 000010 000001 000000 000002 000000 000011 000002 000000 000000 000000 000012 000023 000006 000008 000004 000013 001565 001504 002010 001367 000014 000425 001959 000649 000700 000015 001447 001917 001129 001415 000016 034084 026118 040328 032334 000017 040537 015000 033773 041092 <----- 000018 005771 009092 007999 007512 000019 002709 023378 001790 003117 000020 000167 006238 000109 000136 000021 000135 002369 000099 000093 000022 000039 000622 000025 000041 000023 000153 000123 000026 000023 000024 000986 000178 000564 000500 000025 001872 000292 001291 001515 000026 000049 000269 000112 000081 000027 000010 000561 000011 000014 000028 000003 000296 000016 000009 000029 000005 000035 000014 000002 000030 000001 000008 000006 000000 000031 000001 000008 000006 000001 000032 000011 000002 000004 000000 Rest of the histogram is mostly 00000 values. As far as you may know, is there something i am missing for this cpu ? Thanks a lot, Regards, angelo
