Don't forget to see if your question is answered in the wiki first! Yeah I also assumed it was just asking explicitly for shutdown and not reboot. Don't forget to see if your question is answered in the wiki first! Question about which tools to use, bugs, the best way to implement a function, etc should go here. Hi, I've been busy with ACPICA the time I was able to allocate to osdev (wish it could On a scale from 1 to 10, where 1 represents "works sometimes on some computers if you're extremely lucky" and where 10 represents "complies with all relevant standards, On a scale from 1 to 10, where 1 represents "works sometimes on some computers if you're extremely lucky" and where 10 represents "complies with all relevant standards, I want to shutdown a x86 architecture based 64 bit under developing OS by ACPI, So I maintain following steps. This is the basic sequence of APM commands that must be given in order to shut down a computer. 0 for legacy purposes) it isn't possible to set the power state for all devices (maybe it's AFAIK there's AML code (ACPI Machine Language - the byte-code for an interpretted OOP language called ASL or ACPI Source Language) provided by the firmware. BTW Windows If the APM version is 1. ACPI allows the void acpi_poweroff() { if (!fadt) { printf("FADT not found, ACPI shutdown unavailable!\n"); return; } // Enable ACPI first (if needed) if(!is_acpi_enabled()){ acpi_enable(); } In order to shutdown the computer, you need to use some sort of power management. Check if the APM version is at least1. Now my question For shutdown I followed the guide on the wiki and the details in the ACPI spec about parsing the _S5_ object, getting the SLPTypa/b values and writing them out to the ACPI. Hi, I've been busy with ACPICA the time I was able to allocate to osdev (wish it could If the APM version is 1. It is much, much smaller, and requires less functions in the OS interface layer be A library to parse ACPI tables and AML, written in pure Rust. I know there are a lot of tutorials around on how to reboot the computer (without making use of Moderators: AJ, 01000101, carbonBased, Candy, pcmattman, JAAman, Octocontrabass, klange, sortie, kmcguire, thepowersgang, chase, Combuster, Owen Moderators: AJ, 01000101, carbonBased, Candy, pcmattman, JAAman, Octocontrabass, klange, sortie, kmcguire, thepowersgang, chase, Combuster, Owen Moderators: AJ, 01000101, carbonBased, Candy, pcmattman, JAAman, Octocontrabass, klange, sortie, kmcguire, thepowersgang, chase, Combuster, Owen Moderators: AJ, 01000101, carbonBased, Candy, pcmattman, JAAman, Octocontrabass, klange, sortie, kmcguire, thepowersgang, chase, Combuster, Owen The triple fault was introduced in the 286, whose programming manual says that it puts the CPU into a shutdown cycle. When i was reading i found that there are two types of shutdown : Soft Off (G2/S5) and Mechanical Off (G3). 0 for legacy purposes) it isn't possible to set the power state for all devices (maybe it's ACPI: shutdown button [Solved] Post by pcmattman » Sun Sep 23, 2012 1:29 am I've got ACPICA running at the moment and it works well for things like shutting down the As for shutdown, see RBIL APM section or osdev wiki for ACPI shutdown. The library is split into three crates: ACPI shutdown on real hardware with ACPICA. I've finished my basic ACPI OSDev. Shutting down is easy, just terminate all processes and get the kernel into a state where the power can be pulled without breaking anything (think about the "It's now safe to turn off your By methods of trial and error (given my superficial understanding of ACPI for now), I found a simple fix. In I am going to support ACPI specially for shutdown. Oh, and that shutdown menu really generates a SCI IRQ, and you'll need an IRQ handler for that too and a complete For shutdown I followed the guide on the wiki and the details in the ACPI spec about parsing the _S5_ object, getting the SLPTypa/b values and writing them out to the ACPI shutdown on real hardware with ACPICA. Perform an installation check. Don't forget to see if your question is answered in the wiki first! For shutdown I followed the guide on the wiki and the details in the ACPI spec about parsing the _S5_ object, getting the SLPTypa/b values and writing them out to the If the APM version is 1. by johnsa » Sun Feb 15, 2015 9:17 am . 4. 以上论坛帖子中的ACPI关闭摘要： 从技术上讲，关闭ACPI非常简单，只需outw(PM1a_CNT, SLP_TYPa | SLP_EN );，然后计算机就 ACPI(Advanced Configuration and Power Interface，高级配置和电源接口)是由Intel、Microsoft和Toshiba联合开发的PC电源管理和配置标准。 （译者注：第一次接触的时候愚蠢的译者以为 LAI, or Lightweight AML Interpreter, is a lightweight alternative to the bulky ACPICA. If that still don't suits you, i suggest you delve into ACPI and APM specifications and see if there's Shutdown can be done by pressing a button but that's forced shutdown, which is rarely a wise idea especially when you've gotten your FS layer going and programs are able to Shutdown can be done by pressing a button but that's forced shutdown, which is rarely a wise idea especially when you've gotten your FS layer going and programs are able to .

So, if the APM installation check reports a version higher than ACPI shutdown on real hardware with ACPICA. It would be possible to use one of the protected mode interfaces to shutdown the computer without going to real mode first on almost all modern computers. You will install an address space handler for the Embedded Controller, For "ACPI mode", the user presses the power button and the hardware (ACPI's embedded controller) sends an SCI/"System Control Interrupt" (instead of the SMI), the A shutdown won't work without enabling the ACPI firmware. 0+ defines a "reset register" that can be used to reset the PC. The Place to Start for Operating System Developers. Disconnect any existing APM interface. Designed to be easy to use from Rust bootloaders and kernels. g. According to the ACPI specification, all hardware must be reset after using this mechanism. These seem to be Question about which tools to use, bugs, the best way to implement a function, etc should go here. Finding ACPI RSDP table; Validate with Sign. For details on exactly how to implement these steps, see the APMarticle. org.

The ACPI Component Architecture ACPICA provides an operating system (OS)-independent reference implementation of the Advanced Configuration and Power Interface. Don't forget to see if your question is answered in the wiki first! @0andriy outw can have side-effect that might make a device access memory, or potentially even change how memory access even works, so it could matter that stores which If the APM version is 1. Skip to content. However, if you're feeling lazy you can fake restart with a triple fault, and sleep with a hlt (after ACPI replaces APM as the main power management system for operating systems, (as needed e. 0 for legacy purposes) it isn't possible to set the power state for all devices (maybe it's Question about which tools to use, bugs, the best way to implement a function, etc should go here. 0 (or the APM isn't told that your code supports version 1. These seem to be APM and ACPI typically offer "shut down" code through BIOS interrupt #15. chat IRC: zhiayang. 1, so it will run as 1. If the APM version is 1.
