CONFIG_MIPS_INSANE_LARGE: Support for large 64-bit configurations

General informations

The Linux kernel configuration item CONFIG_MIPS_INSANE_LARGE has multiple definitions:

Support for large 64-bit configurations found in arch/mips/Kconfig

The configuration item CONFIG_MIPS_INSANE_LARGE:

• prompt: Support for large 64-bit configurations
• type: bool
• depends on: CONFIG_CPU_R10000 && CONFIG_64BIT
• defined in arch/mips/Kconfig
• found in Linux kernels: 2.6.0–2.6.39, 3.0–3.1

Help text

MIPS R10000 does support a 44 bit / 16TB address space as opposed to previous 64-bit processors which only supported 40 bit / 1TB. If you need processes of more than 1TB virtual address space, say Y here. This will result in additional memory usage, so it is not recommended for normal users.
