Is there a way for a non-kernel-developer or plain FPC/Laz user to
control what is stored in cpu cache ? I thought cache management
is done transparently to userspace...?
Yes, it's transparent. But my answer wasn't related to whether the
memory can be controlled by the user or not, but whether it's the
fastest or not.
Btw: In FPC you can use "Prefetch(SomeVariable)" to prefetch the data of
the variable into the cache (if the platform supports something like
that). See also:
