Abstract

A method for enabling global variable read/write operations in a pre-EFI Initialization (PEI). The method includes the generation of a driver image. The driver image includes at least a code (i.e., text) section, a data section, and a relocation section. A first round fixing on the driver image is performed to fix all address data items with absolute non-volatile memory addresses. A second round fixing on the driver image is performed to fix all address data items fixed in the first round fixing that point to the data section with absolute Cache-As-RAM (Cache-As-Random Access Memory) addresses. The fixed driver image is burned into a non-volatile memory device. Upon booting the non-volatile memory device, the data section of the burned driver image is copied to a Cache-As-RAM (CAR), wherein execution of executable code in the text section enables static and global variables to have read/write access from the CAR.

Description

For use the method for global variable based on the pre-EFI initialization module in the firmware of EFI

Technical field

The present invention summarily relates to firmware.More specifically, use the method for global variable during the pre-EFI that the present invention relates in the platform innovation framework that is used for EFI (pre-Extensible Firmware Interface) initial phase.

Background technology

By the Santa Clara's that is positioned at CA

The platform innovation framework that is used for EFI (Extensible Firmware Interface) of company's exploitation is the architecture interface with one group of stalwartness of C realization, and its design is in order to carry out from power on to the required the whole series operation of the platform initialization that control is transferred to operating system.The platform innovation framework (being also referred to as " framework ") that will be used for EFI is divided into two Main Stage: pre-EFI initialization (PEI) stage and driving execution environment (DXE) stage.The PEI stage is carried out smallest processor, chipset and the platform configuration of supporting that storer is found.The DXE stage advances the PEI stage by the initialization of finishing platform, processor and chipset devices.

There is not available storer in the PEI stage.Though there is not available storer, can serve as RAM (random access storage device) by temporary transient initialization processor high-speed cache, therefore can be stored in heap and stack in the high-speed cache.This provides the possibility of moving the module of high-level programming language compiling in the PEI stage.

Known limitation in the framework is, PEI in the stage module global variable as read-only variable, promptly can not revise global variable.Because unavailable, be placed in the flash memory to all data (data) and the no reorientation of code (code) section at PEI stage storer.

Well known fact is, easy modification the data of the data in the flash memory in other conventional memory devices.Though the PEI code can call the write access to the global variable in the data segment of flash memory, can not revise global variable.This restriction provides several shortcomings of PEI module.The first, hindered the ability of sharing module global variable between function.All variablees that need between function to share must transmit back and forth by heap or stack.This can cause the increase greatly of code length.Same because the PEI code moves in flash memory, so can not compress.The second, it reduces startability.The increase of code needs the more processor cycle to decipher and move.In addition, do not enable, cause operational efficiency slow, particularly because to the frequent global variable access of flash memory at this phase process device high-speed cache.The 3rd, it stops firmware development person to develop and test their code like a cork.

Therefore, need make the method that in for pre-EFI initialization (PEI) environment, can support global variable based on the firmware of EFI.Also need to make the method that during the PEI stage, can revise global variable.

Get back to decision box 408, if there is not more point to be analyzed in .reloc section 106, then method proceeds to frame 410, and first round revision herein finishes.

The first round, revision was also shown in the flash memory 302 of Fig. 3.Shown in the flash memory 302 of Fig. 3 is example points, the Data Position B in the .data section 104 and absolute flash address Ma in the .reloc section 106 and data code position A and C and the absolute flash address Mc in Mb and the .text section 102.Ma is the absolute flash address that is used for code position A.Mb is the absolute flash address that is used for Data Position B.Mc is the absolute flash address that is used for code position C.

Demonstration pilot project Ra, Rb and Rc are shown in .reloc section 106 highlightedly.Ra comprises the relocation information of pointing to code position A (being arranged in .text section 102).Upgrade the address date at A place, position with the absolute flash address Ma that is arranged in .data section 104.Rb comprises the relocation information of pointing to Data Position B (being arranged in .data section 104).Upgrade the address date at B place, position with the absolute flash address Mb that is arranged in .data section 104.Last Rc comprises the relocation information of pointing to code position C (being arranged in .text section 102).Upgrade the address date at C place, position with the absolute flash address Mc that is arranged in .text section 102.

Flash memory 302 ' illustrates second and takes turns the revision method.Flash memory 302 ' shows .reloc section 106 .data section 104 ' and the .text section 102 ' of outstanding example points Ra, Rb and Rc..data section 104 ' comprises Data Position B and absolute CAR address Mb ' and Ma '..text section 102 ' comprises position A and C and absolute flash address Mc.Note, in flash memory 302 ' (.data section 102 '), revise the .text section 102 of flash memory 302 to adapt to the address change of Ma '.

If in .data section 104, find the address, for example Mb of flash memory 302 and Ma, positive access static of code or global variable in this expression .text section 102.Because the .data section 104 ' of flash memory 302 ' will copy to CAR 304, so must upgrade these addresses (Mb and Ma) with the absolute CAR address of reflection as shown in the .data section 104 ' in the flash memory 302 ' (Mb ' and Ma ').Therefore, need further repair by the gap between addition specified flash plot and the CAR plot.For other address outside the .data section 104 ' of .data section 104 that is positioned at flash memory 302 or flash memory 302 ' (for example, the Mc that in .text section 102 and .text section 102 ', finds), do not need further repairing, because these addresses will be retained in the flash memory.In other words, will in flash memory, move .text section 102.

By checking the address of having revised in the first round revision, be easy to judge whether the address is arranged in data section 104.To be redirected to the CAR304 in the .data section 104 ' to the all-access of the flash memory address in the .data section 104.Flash memory address in being redirected .data section 104 copies to CAR 304 with .data section 104 ' from flash memory 302 ' with after obtaining .data section 104 '.At this moment, the moved driver module 100 with the .data section 104 ' of storing in CAR zone 304 and operating can normally move.This has improved startability significantly, because all are static and global variable access occurs among the CAR 304 rather than in the flash memory after the reorientation.Therefore, by to pointing to the other repairing of address applications of .data section 104, might from whole image layout, separately and it be redirected to the address of any other appointment after the first round revision to the .data section.By .data section 104 ' is navigated among the CAR 304, at PEI in the stage, can move driver module 100 and can have write access global variable.

As shown in flash memory 302 ', with the previous address date of having revised (Mb) at absolute CAR address Mb ' renewal B place, position, and the previous address date of having revised (Ma) that upgrades A place, position with absolute CAR address Ma '.Because the address date of having revised (Mc) at position C place is arranged in .text section 102, and the .text section will be retained in the flash memory, therefore will not upgrade the address date of having revised (Mc) at C place, position.

CAR 304 is parts of processor high speed buffer memory, and wherein .data section 104 ' is replicated.As implied above, after flash memory space, firmware loader can copy to CAR from flash memory with .data section 104 ' with firmware burning..data section 104 ' is transferred to CAR 304 and is made the static and global variable of PEI have read by CAR 304.
