Hi Dirk, If I want to apply the rt patch to GIT 2.6.25-davinci1, which patch do I use from http://www.kernel.org/pub/linux/kernel/projects/rt? I can't find one of the form patch-2.6.25-rt*; instead, I see patch-2.6.25.4-rt1.bz2 as the oldest and patch-2.6.25.8-rt7.gz as the latest. Our Davinci system is a real-time system and we need the patch to meet critical real-time requirements.
According to the RT wiki site (http://rt.wiki.kernel.org/index.php/Frequently_Asked_Questions#Optional_parameters_for_configuring_realtime_kernel.2C_but_they_effect_realtime_performance.3F), userland applications shouldn't protect data with semaphores but but use PTHREAD_PRIO_INHERIT mutexes instead; this requires glibc 2.5 but our MVL4.0 toolchain is based off glibc 2.3; is it possible to replace it with glibc 2.5 in the MVL4.0 toolchain? It seems like I need to rebuild the whole toolchain if I want to switch to using glibc 2.5. If this is the case, does anyone know if the source to the MVL toochain is available for rebuilding a toolchain using the latest GCC, glibc, etc? Thanks.

Update to v2.6.23-rc4: patch-2.6.23-rc4-rt1.bz2 [1] applies cleanly as well. Additional DaVinci specific patch in attachment. Best regards Dirk [1] http://www.kernel.org/pub/linux/kernel/projects/rt/
