That's interesting, I'm unable to reproduce the issue on my 4430 when using the tilt-tracking kernel. Just used the same SD card I'm able to reproduce the issue on my 4460. -- You received this bug notification because you are a member of TI OMAP Developers, which is subscribed to linaro-landing-team-ti. https://bugs.launchpad.net/bugs/873453 Title: odd timing behaviour on panda Status in Linaro Texas Instruments Landing Team: Confirmed Status in Linaro Ubuntu Evaluation Builds: Confirmed Bug description: I've got a set of benchmarks that use clock_gettime like: clock_gettime(CLOCK_REALTIME, &tbefore); for(l=0;l<numloops;l++) { dostuff } clock_gettime(CLOCK_REALTIME, &tafter); nsdiff=(double)(tafter.tv_nsec - tbefore.tv_nsec); nsdiff+=1000000000.0 *(tafter.tv_sec - tbefore.tv_sec); and I've just reinstalled our local panda to using Linaro 11.09 (kernel 3.0.0-1404-linaro-lt-omap) and it's starting to get weird timing artifacts. For example: smarter_strlen_ldrd: ,102400, loops of ,62, bytes=6.054688 MB, transferred in ,3936768.000000 ns, giving, 1537.984331 MB/s smarter_strlen_ldrd: ,102400, loops of ,32, bytes=3.125000 MB, transferred in ,0.000000 ns, giving, inf MB/s smarter_strlen_ldrd: ,102400, loops of ,16, bytes=1.562500 MB, transferred in ,4180909.000000 ns, giving, 373.722557 MB/s Now there is no way that loop took 0.000000 ns! Running the same binary on an older installation runs fine.
