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, 6.0–6.12

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
