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.

Regards,
Andy Ngo

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
