ACPI模块初始化是系统引导过程中由内核初始化驱动的。ACPI是一种电源管理和配置接口标准，用于操作系统与计算机硬件之间的通信。ACPI模块的初始化在系统引导过程中起到关键作用。在内核初始化驱动时，会调用acpi_early_init函数来初始化ACPI全局变量，装载各种ACPI表，初始化ACPI名字空间等。接着，内核会调用a...
在这个函数中,会做操作系统的设备等一系列初始化,与ACPI最关键的地方在这个函数:acpi_early_init,这里完成的工作主要有如下: 代码语言:javascript 复制 1acpi_early_init 2acpi_reallocate_root_table 3acpi_initialize_subsystem4(drivers/acpi/acpica/Tbxfload.c)51.acpi_load_tables:6--->acpi_status __ini...
而通过我抓取的日志和自学总结来看,从vmlinuz角度来看,内核启动和初始化做了以下几件事情: 1、实模式early kernel initial 阶段。 vmlinuz从bios 手里接管 bios已经生成的硬件资源表,初始化架构。 ACPI接口初始化; STOLEN内存/MEM HOLE的起始终止位置; numa 内存分布,以及内存zone初始化。 中断架构 lapic + ioapic ...

The call chain goes to acpi_subsystem_init which is a thin wrapper around acpi_enable_subsystem. A couple comments in this function may tell why we had to waarch_post_acpi_subsys_initit this long to enable the ACPI code (although not why we needed the memory so early) Initialize ACPI ...
During early init (when acpi_permanent_mmap has not been set yet) this routine simply calls __acpi_map_table() to get the job done. This is not the same virtual memory map as used by the Linux Kernel. This is an ACPI specific mapping. ACPI is a hardware (coprocessor?) subsystem th...
