Expand description

Contains the addresses of all memory mappings set up by set_up_mappings.

Fields§

§entry_point: VirtAddr

The entry point address of the kernel.

§stack_top: VirtAddr

The (exclusive) end address of the kernel stack.

§used_entries: UsedLevel4Entries

Keeps track of used entries in the level 4 page table, useful for finding a free virtual memory when needed.

§framebuffer: Option<VirtAddr>

The start address of the framebuffer, if any.

§physical_memory_offset: Option<VirtAddr>

The start address of the physical memory mapping, if enabled.

§recursive_index: Option<PageTableIndex>

The level 4 page table index of the recursive mapping, if enabled.

§tls_template: Option<TlsTemplate>

The thread local storage template of the kernel executable, if it contains one.

§kernel_slice_start: PhysAddr

Start address of the kernel slice allocation in memory.

§kernel_slice_len: u64

Size of the kernel slice allocation in memory.

§kernel_image_offset: VirtAddr

Relocation offset of the kernel image in virtual memory.
