CONFIG_ARC_KVADDR_SIZE: Kernel Virtual Address Space size (MB)

General informations

The Linux kernel configuration item CONFIG_ARC_KVADDR_SIZE has multiple definitions:

Kernel Virtual Address Space size (MB) found in arch/arc/Kconfig

The configuration item CONFIG_ARC_KVADDR_SIZE:

• prompt: Kernel Virtual Address Space size (MB)
• type: int
• depends on: (none)
• defined in arch/arc/Kconfig
• found in Linux kernels: 4.15–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

The kernel address space is carved out of 256MB of translated address space for catering to vmalloc, modules, pkmap, fixmap. This however may not suffice vmalloc requirements of a 4K CPU EZChip system. So allow this to be stretched to 512 MB (by extending into the reserved kernel-user gutter)

Kernel Virtaul Address Space size (MB) found in arch/arc/Kconfig

The configuration item CONFIG_ARC_KVADDR_SIZE:

• prompt: Kernel Virtaul Address Space size (MB)
• type: int
• depends on: (none)
• defined in arch/arc/Kconfig
• found in Linux kernels: 4.7–4.14
