启动 Linux/LoongArch
====================

BootLoader传递给内核的信息
==========================
LoongArch支持ACPI和FDT启动,需要传递给内核的信息包括memmap、initrd、cmdline、可
选的ACPI/FDT表等。
内核在 `kernel_entry` 入口处被传递以下参数:
- a0 = efi_boot: `efi_boot` 是一个标志,表示这个启动环境是否完全符合UEFI
的要求。
- a1 = cmdline: `cmdline` 是一个指向内核命令行的指针。
- a2 = systemtable: `systemtable` 指向EFI的系统表,在这个阶段涉及的所有
指针都是物理地址。
Linux/LoongArch内核镜像文件头
=============================
内核镜像是EFI镜像。作为PE文件,它们有一个64字节的头部结构体,如下所示::
u32 MZ_MAGIC /* "MZ", MS-DOS 头 */
u32 res0 = 0 /* 保留 */
u64 kernel_entry /* 内核入口点 */
u64 _end - _text /* 内核镜像有效大小 */
u64 load_offset /* 加载内核镜像相对内存起始地址的偏移量 */
u64 res1 = 0 /* 保留 */
u64 res2 = 0 /* 保留 */
u64 res3 = 0 /* 保留 */
u32 LINUX_PE_MAGIC /* 魔术数 */
u32 pe_header - _head /* 到PE头的偏移量 */
Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
