[310] Application class data sharing (CDS): CDs are introduced in JDK5 to improve the performance of JVM startup while reducing the resource footprint of multiple virtual machines running on the same physical or virtual machine.
JDK10 extends the CDS to the class loader that allows the internal system, the class loader for the internal platform, and the custom class loader
The DT block format
This chapter defines the format of the FDT (flattened device tree) passed to the kernel. The properties it contains and the attributes required by the kernel are described in subsequent chapters.Note: The DT block should be loaded into the main memory, the kernel needs to be able to access the DT block in both real mode and protected mode, so the first address of DT block cannot be remapped. The Boot loader is responsible for loading the DT block into memory and then pas
