Hi,
I need to build RT enabled kernel.
With kernels up to and including 5.2, there was fairly easy procedure
for building RT enabled kernel - apply patch, then RT features are
immediately available in "make xxxconfig".
Now, with 5.4. CONFIG_PREEMPT_RT is merged, but it depends_on
ARCH_SUPPORTS_RT that, in turn, does not set for any architecture.
How should I proceed from here? Am I supposed to just set
ARCH_SUPPORTS_RT for my architecture? Do I need any other patches to
start? If yes, where to get it? I see not all patches in the 5.2 bundle
are merged mainline.
Thanks, Vladimir
