Hello, I have been using valgrind --leak-check=yes on an ARM-Cortex-A9 board to debug an application (based on gstreamer), and find it much slower when the board is booted in SMP mode than it UP mode. I takes about 20 minutes before it detects an error: ==1393== Invalid read of size 1 ==1393== at 0x4831E64: strncmp (mc_replace_strmem.c:534) ==1393== by 0x5EB1923: pixman_arm_read_auxv (in /usr/lib/libpixman-1.so.0.22.2) After that, execution is about as fast as in UP mode. Is there any difference in the beginning stage of valgrind between SMP and UP modes? Using the 'top' command shows that the system is busy at the memcheck-arm-li process. Where can I look at to isolate the problem? Thanks! Christophe. |
