LLC coloring needs to know the last level cache layout in order to make the best use of it. This can be probed by inspecting the CLIDR_EL1 register, so the Last Level is defined as the last level visible by this register. Note that this excludes system caches in some platforms. Static memory allocation and cache coloring are incompatible because static memory can't be guaranteed to use only colors assigned to the domain. Panic during DomUs creation when both are enabled.
