I think this has a slight grammar problem.
What about this instead?
The @code{glibc.tune.cached_memopt=[0|1]} tunable allows the user to
enable optimizations recommended for cacheable memory. If set to
@code{1}, @theglibc{} assumes that the process memory image consists of
cacheable (non-device) memory only. The default, @code{0}, indicates
that the process may use device memory.
(I think it's best not to mention string functions here because it is
impossible to describe how glibc.tune.cached_memopt affects them due to
compiler optimizations.)
Thanks,
Florian
