CONFIG_KERNEL_START_BOOL: Set custom kernel base address

General informations

The Linux kernel configuration item CONFIG_KERNEL_START_BOOL has multiple definitions:

Set custom kernel base address found in arch/powerpc/Kconfig

The configuration item CONFIG_KERNEL_START_BOOL:

• prompt: Set custom kernel base address
• type: bool
• depends on: CONFIG_ADVANCED_OPTIONS
• defined in arch/powerpc/Kconfig
• found in Linux kernels: 2.6.15–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

This option allows you to set the kernel virtual address at which the kernel will be loaded. Normally this should match PAGE_OFFSET however there are times (like kdump) that one might not want them to be the same.

Say N here unless you know what you are doing.

Set custom kernel base address found in arch/microblaze/Kconfig

The configuration item CONFIG_KERNEL_START_BOOL:

• prompt: Set custom kernel base address
• type: bool
• depends on: CONFIG_ADVANCED_OPTIONS
• defined in arch/microblaze/Kconfig
• found in Linux kernels: 2.6.31–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

This option allows you to set the kernel virtual address at which the kernel will map low memory (the kernel image will be linked at this address). This can be useful in optimizing the virtual memory layout of the system.

Say N here unless you know what you are doing.

Set custom kernel base address found in arch/ppc/Kconfig

The configuration item CONFIG_KERNEL_START_BOOL:

• prompt: Set custom kernel base address
• type: bool
• depends on: CONFIG_ADVANCED_OPTIONS
• defined in arch/ppc/Kconfig
• found in Linux kernels: 2.5.45–2.5.75, 2.6.0–2.6.26
