Functions | |
static uintptr_t | k_mem_phys_addr (void *virt) |
Get physical address from virtual address. | |
static void * | k_mem_virt_addr (uintptr_t phys) |
Get virtual address from physical address. | |
void | k_mem_map_phys_bare (uint8_t **virt_ptr, uintptr_t phys, size_t size, uint32_t flags) |
Map a physical memory region into the kernel's virtual address space. | |
void | k_mem_unmap_phys_bare (uint8_t *virt, size_t size) |
Unmap a virtual memory region from kernel's virtual address space. | |
void * | k_mem_map_phys_guard (uintptr_t phys, size_t size, uint32_t flags, bool is_anon) |
Map memory into virtual address space with guard pages. | |
void | k_mem_unmap_phys_guard (void *addr, size_t size, bool is_anon) |
Un-map memory mapped via k_mem_map_phys_guard(). | |
