why FPGA reserved some resources when using opencl

[well]

Hi intel team,

When compiling an empty code using opencl on intel FPGA, I noticed that some resources are reserved. Such as 40,650 ALUTs (9%), 52,976 FFs (6%), and 283 RAM blocks (11%) reserved and not available for use.

I need to know why they are reserved ??? for what goal ??

These are infrastructure resources - memory controller, PCI-E controller...

They generates anyway, even code is without kernel.
