Hi everybody, I am using a mpc5200 chip with a linux 2.6.33.7-rt29. I am using the ELDK toolchain :
ppc_6xx-gcc -v Target: powerpc-linux Configured with: /opt/eldk/build/ppc-2008-04-01/work/usr/src/denx/BUILD/crosstool-0.43/build/gcc-4.2.2-glibc-20070515T2025-eldk/powerpc-linux/gcc-4.2.2/configure --target=powerpc-linux --host=i686-host_pc-linux-gnu --prefix=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/powerpc-linux --disable-hosted-libstdcxx --with-headers=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/powerpc-linux/powerpc-linux/include --with-local-prefix=/var/tmp/eldk.UZpAG7/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/powerpc-linux/powerpc-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++,java --enable-shared --enable-c99 --enable-long-long --without-x Thread model: posix gcc version 4.2.2 When I have the CONFIG_DEBUG_KERNEL flag, the latencies I am mesuring are better than when the flag is off. And the jitter is lower... I must tell I am confused. I have no explanation about that, except maybe optimisations which would be different when the -g flag is added... If any of you has an idea, I am looking forward for your response :). Thanks in advance, Best Regards.
