Function Documentation

sys_mm_is_phys_addr_in_range()

bool sys_mm_is_phys_addr_in_range

(

uintptr_t

phys

)

#include <zephyr/sys/mem_manage.h>

Check if a physical address is within range of physical memory.

This checks if the physical address (virt) is within permissible range, e.g. between :kconfig:option:CONFIG_SRAM_BASE_ADDRESS and (:kconfig:option:CONFIG_SRAM_BASE_ADDRESS + :kconfig:option:CONFIG_SRAM_SIZE).

Note

Only used if :kconfig:option:CONFIG_KERNEL_VM_USE_CUSTOM_MEM_RANGE_CHECK is enabled.

Parameters

phys	Physical address to be checked.

Returns

True if physical address is within range, false if not.

sys_mm_is_virt_addr_in_range()

bool sys_mm_is_virt_addr_in_range

(

void *

virt

)

#include <zephyr/sys/mem_manage.h>

Check if a virtual address is within range of virtual memory.

This checks if the virtual address (virt) is within permissible range, e.g. between :kconfig:option:CONFIG_KERNEL_VM_BASE and (:kconfig:option:CONFIG_KERNEL_VM_BASE + :kconfig:option:CONFIG_KERNEL_VM_SIZE).

Note

Only used if :kconfig:option:CONFIG_KERNEL_VM_USE_CUSTOM_MEM_RANGE_CHECK is enabled.

Parameters

virt	Virtual address to be checked.

Returns

True if virtual address is within range, false if not.
