Description of the Invention: [Technical Field] The present invention relates to a computer information technology, and more particularly to a method and system for controlling data exchange between a power management unit and a power-on main control unit, which can be applied to To a computer platform, the computer platform must be equipped with at least one BIOS (Basic Input/Output System) boot control unit supporting SMI (System Management Interrupt) system management interrupt function and an ACPI (Advanced Configuration and Power) interface power management The unit is configured to provide a data exchange control function between the ACPI power management unit and the BIOS boot control unit. [Prior Art] ACPI (Advanced Configuration and Power Interface) is a high-performance computer configuration and power management technology. It has been widely used in various computer platforms, including network servers and desktop PCs. Notebook computers, etc., are used to provide a highly efficient configuration and power management function for these computer platforms, thereby making the application of the power supply more economical and efficient. In the research and development of ACPI functions, most of the current industry uses ASL (ACPI Source Language) programming language to write ACPI function modules; and in practical applications, it is necessary to compile ASL original code into AML in machine-rock form. (ACPI Machine Language) code, then burn the AML code into the flash ROM, and then use the ACPI driver to perform the required power management functions. 5 19212 1306198
' ‘ 於實際操作時，ACPI驅動程式常有需要與BIOS -(Basic Input/Output System)開機主控單元，特別是其中之 POST(Power On Self Test)電源開啟自行涓ij試程式，來產生 一些互動之資料交流關係。然而於實務上，由於BIOS功 能模組於研發上目前大都係採用C程式語言或組合語言來 撰寫，因此電腦工程師於發展某一 ACPI功能時，便有需 要同時以ASL程式語言來撰寫ASL程式碼並同時用C程 式語言（或組合語言）來撰寫相關之BIOS程式碼。由於ASL ®和C (或組合語言）為二種語法完全不同的程式語言，因此 顯然會對ACPI的研發人員造成很大的不便和困擾。此外， 每當晶片組需更換、硬體設計需修改、或BIOS程式碼需 要修正時，電腦工程師不僅需修正相關之BIOS程式碼， 且亦需同時修正相關之ASL程式碼，使得ACPI功能的修 正過程頗為費時費力而沒有效率。再且，由於ACPI功能 之ASL/AML程式碼與晶片組和硬體有關，因此使得ACPI 籲功能的ASL/AML程式碼不具有跨平台的執行能力。 【發明内容】 鑒於以上所述習知技術之缺點，本發明之主要目的便 是在於提供一種電源管理單元與開機主控單元間資料交流 控制方法及系統，其可讓電腦工程師於有需要修改ACPI 功能時，完全不必去修改相關之ASL/AML程式碼，使得 ACPI功能的修正過程更為方便而有效率。 本發明之另一目的在於提供一種電源管理單元與開 機主控單元間資料交流控制方法及系統，其可讓ACPI功 6 19212 1306198 •能的ASL/AML程式碼具有跨平台的執行能力。 < 纟發明t電源管理單元與開@主控單元間資料交流 控制方法及系統係設計來應用於搭载— 電腦平台須至少配備有-支請系統管^ 則s開機主控單元和―ACPI電源管理單元，用以= :C:I電源管理單元和該腦開機主控單元之間提供一資 料父流控制功能。 、 押制= 月？Γ管理單元與開機主控單元間資料交流 法至>、包含:⑴回應該電源管理單^以系統管理中 該電；：=的各種要求訊息而產生對應之致能訊息；若 理单凡發出-開機主控單元資料讀取要求訊自， :::r機主控單元資料讀取致能訊息；若該電源Ϊ理 單元議送要求訊息，物-開 =控單元功能啟動要求訊息，則發出一開機主= 訊息而執行^開機主控單元資料讀取致能 主控單亓所雇機早兀貧料讀取程序’藉以從該開機 " 屬之一系統組態資料暫存區中讀取出其中所暫 :系統組態資料；並將所讀取出之系統組 自 ’（回應該職主控單元資料傳送致能訊 二機主控單元f料傳送程序，藉此而將一組操 回庫兮源管理單元傳送給該開機主控單元；以及⑷ 口應5亥開機主如^置； （） 單元Μ 力能啟動致能訊息而啟動該開機主控 早兀來執行一對應之功能。 19212 7 1306198 ‘於實體架構上，本發明 元間資料交流控制系統至少包含理早-與開機主控單 回應模組，其可回應該電源管理中斷訊息 所發出的各種要求訊息而產生對 ^先官理中斷方式 營理單元發出一開機主控單 ^ 若該電源 一開機主控單元資4項取要求訊息，則發 早兀貝科躓取致能訊息 出一開機主控單元資料傳送要立、白 原官理早元發 單元資料傳送致能訊自.若/一則發出-開機主控 控單元功能啟動要求訊息，則發出 =:=出：開機主 動致能訊息；（B)—開機-少 控單兀功能啟 應該系統管理中斷1自!貝料靖取模組’其可回 料讀取致能所發出的開機主控單元資 貝取级以息而執行一開機貝 以從該開機主控單元所屬夕β 凡貝科§貝取程序，藉 出盆由糾心系統組態資料暫存區中續取 出其中所暫存之系統纽態資料；並將所 中項取 資料再透過該线管理+斷 …统組態 管理單元.rr、-叫擔 果組來回傳給該電源 兮备γ 幵機主控單元資料傳送模組，1可回岸 該糸統官理中斷訊息回應模 -口應 傳自n 听贫出的開機主控單元資料 :广訊息而執行一開機主控單元資 而將:組操細從該電源管理單元傳送給該開：二 疋’以及（D)㈤機主控單元功能啟動模組，其 ς 統管理中斷訊息回應模組所發出的開機主控單元功：= 致能訊息而啟動該開機主控單元來執行一對庫2動 .本發明之電源管理單元與開機主控單元間資料月^ 控制方法及系統的特點在於令簡電源管理單元完全利 k 19212 1306198 ' 用SMI系統管理中斷處理機制來處理其與BIOS開機主控 • 單元之間的資料交流。此特點可讓電腦工程師於有需要修 改ACPI功能時，完全不必去修改ACPI驅動程式所屬之 ASL/AML程式碼，使得ACPI功能的修正過程更為方便而 有效率，且可讓ACPI功能的ASL/AML程式碼具有跨平台 的執行能力。 【實施方式】 以下即配合所附之圖式，詳細揭露說明本發明之電源 •管理單元與開機主控單元間資料交流控制方法及系統之實 施例。 第1圖即顯示本發明之電源管理單元與開機主控單元 間資料交流控制系統（如標號100所指之方塊）的應用方 式。如圖所示，本發明之電源管理單元與開機主控單元間 資料交流控制系統100於實際應用上係搭載至一電腦平台 10，例如為網路伺服器、桌上型個人電腦、或筆記型電腦， •且該電腦平台10須至少配置有一開機主控單元20和一電 源管理單元30 ;其中該開機主控單元20例如為一 BIOS(BasicInput/OutputSystem)功能模組，而該電源管 理單元 30 則例如一 ACPI (Advanced Configuration and Power Interface)之高階組態及電源介面的功能模組。 於實際操作時’本發明之電源管理單元與開機主控單 元間資料交流控制系統1 〇〇即可對該ACPI電源管理單元 3〇和該BIOS開機主控單元2〇二者之間提供一資料交流機 制’藉此而讓ACPI電源管理單元3〇可從bI〇s開機主控 9 19212 1306198' ' In actual operation, ACPI drivers often need to boot with the BIOS - (Basic Input / Output System), especially the POST (Power On Self Test) power-on 涓 ij test program to generate some Interactive data exchange relationship. However, in practice, since most of the BIOS function modules are written in C programming language or combination language, it is necessary for computer engineers to write ASL programming code in ASL programming language when developing an ACPI function. At the same time, the C program language (or combination language) is used to write the relevant BIOS code. Since ASL ® and C (or combination language) are two completely different programming languages, it is obviously inconvenient and troublesome for ACPI developers. In addition, whenever the chipset needs to be replaced, the hardware design needs to be modified, or the BIOS code needs to be corrected, the computer engineer not only needs to correct the relevant BIOS code, but also needs to correct the relevant ASL code at the same time to make the correction of the ACPI function. The process is time consuming and labor inefficient. Moreover, since the ASL/AML code of the ACPI function is related to the chipset and hardware, the ASL/AML code of the ACPI call function does not have cross-platform execution capability. SUMMARY OF THE INVENTION In view of the above disadvantages of the prior art, the main purpose of the present invention is to provide a data exchange control method and system between a power management unit and a boot main control unit, which allows a computer engineer to modify ACPI as needed. In the function, it is not necessary to modify the relevant ASL/AML code, so that the correction process of the ACPI function is more convenient and efficient.

This feature allows the computer engineer to modify the ACPI function without having to modify the ASL/AML code that the ACPI driver belongs to, making the ACPI function correction process more convenient and efficient, and allowing the ACPI function to be ASL/ AML code has cross-platform execution capabilities.

When the beta control unit 2 is executed, the self-test program is usually installed by itself (for example, communication port, PS2_KB/MS, floppy disk). The system group of the machine, parallel, etc.) is poor (that is, the hardware is equipped with the enabled state or the disabled state), all temporarily stored in the system configuration data temporary storage area 21; therefore, the boot control unit The data reading wheel set 11G can read the required system configuration data from the system configuration data temporary storage area 21 and transfer it back to the ach power management unit 30. The power-on main control unit π # material transfer module 12G can respond to the system management interrupt message response module 1G1 issued (4) off the master control unit to transfer the enable message and execute the 1 machine master unit f material transfer program, thereby making a group of poor materials (for example, current The name of the executed (four) system) from the ACPI power management The %% is sent to the s boot master unit. 19212 12 1306198 'This function allows the ACPI power management unit 30 to transmit any data to the BIOS boot control unit 20 through the SMI system interrupt handling mechanism. The booting module 130 can activate the BIOS booting control unit 20 to perform a corresponding function in response to the booting main control unit function enable enable message sent by the system management interrupt message response module 101, for example, to enable the PS2- KB/MS wake-up mechanism, enable Wakeup on LAN, Wakeup on Ring, clear wake-up status flag, stop fan operation, set power indicator light status, The current system sleep state (SO, S1, S4 or S5) is notified to the BMC (Baseboard Management Controller) host control unit, and so on. This function allows the ACPI power management unit 30 to command the BIOS boot master unit 20 to perform certain functions that are not suitable for execution by the ACPI power management unit 30 through the SMI system interrupt handling mechanism. For example, before the computer platform 10 enters the sleep state, the work of two time points must be performed by the intervention of the BIOS boot control unit 20; wherein the first time point of φ is the _PTS program in the ACPI (Method). When it is executed, the second time point is when the hardware of the system enters the last time point of the sleep state of S1-S5. After the computer platform 1 〇 leaves the sleep state, there is a time point for the work to be executed by the BIOS boot control unit 20; this time point is when the WAK program (Method) is executed in the ACPI (that is, from S1) - When the sleep state of S5 is woken up).
