CONFIG_KERNEL_RAM_SIZE
¶
Total size of RAM mappings in bytes
Type: hex
Help¶
Indicates to the kernel the total size of RAM that is mapped. The kernel expects that all physical RAM has a memory mapping in the virtual address space, and that these RAM mappings are all within the virtual region [KERNEL_VM_BASE..KERNEL_VM_BASE + KERNEL_RAM_SIZE).
Default¶
0x0
