Hi UEFI community,=

 

I=92d like to inform yo= u about an update in the CdePkg branch of  edk2-staging.

https://github.com/tianocore/edk2-staging/tree/CdePkg= #cdepkg

 

The goal of the CdeP= kg is to provide an ANSI C Interface for UEFI POST drivers,

that enables BIOS engin= eers to (more) easily port standard C programs or libraries

(e.g. the openSSL libra= ry, already done) to POST drivers.

 

Furthermore the ANSI= C Interface is disseminated widely, also it=92s bugs and pitfalls are known very w= ell

by a broad range of IT professionals and may help t= o be better supportable by the open source initiative

compared to the proprietary interface that is avail= able today in Tianocore UEFI.=

 

Now 20 new ANSI C funct= ions m= emcpy(), memmove(), strcpy(), strncpy(), strcat(), strncat(),

memcmp(), strcmp(), strncmp(), memchr(), strchr(), strcspn()= , strpbrk(),

strrchr(), strspn(), strstr(), strtoc(), memset(), strerror(= ) and strlen()

are introduced for P= EI and DXE.

 

Currently there are 6= examples implemented:

    Subject: [edk2-devel] [staging/branch]: CdePkg - C Development Envi= ronment Package

     

    Hi UEFI community,=

     

    I=92d like to introduce= the CdePkg to edk2-staging.

     

    Some time ago I decide= d to write my own ANSI C Library for UEFI Shell and POST.=

     

    The UEFI Shell library= (=93Torito C Library=94) has been production-ready for more than one year.=

    The POST version of th= e library (=93CdeLib=94) is not yet fully tested.

     

    I will be demonstratin= g my verification procedure in the upcoming weeks on EDK2 STAGING  h= ttps://github.com/tianocore/edk2-staging/tree/CdePkg

     

    Currently there are 3 examples implemented:

    1. = argvc: https://github.com/tianocor= e/edk2-staging/blob/CdePkg/CdeValidationPkg/HOSTED_ENV/argcv/main.c#L57=

    argc/argv handling acco= rding to https://msdn.microsoft.com/en-us/library/a1y7w461.aspx

    1. = systeminterfacePEI: https://github.com/= tianocore/edk2-staging/blob/CdePkg/CdeValidationPkg/SYSTEM_IF/systeminterfa= cePEI/main.c#L57

    demonstration, how PeiServices and FileHandle are passed into main()

    1. = systeminterfaceDXE: https://github.com/= tianocore/edk2-staging/blob/CdePkg/CdeValidationPkg/SYSTEM_IF/systeminterfa= ceDXE/main.c#L57

    demonstration, how SystemTable= and ImageHandle are passed into main()

     

    Upcoming next demonstr= ation will be the clock() function end of this week

     

    The idea is to bring t= he ANSI C Library interface into POST drivers.

    This will:<= /span>

    1. eas= e porting tasks
    2. allow cross development
    3. allow develo= pers to focus on their aims, because they aren=92t forced to keep in mind a lo= t of additional info (e.g. RShiftU64)
    4. provide all intrisics to allow the compiler to be a =93C compiler=94

    (e.g. char b= uffer[256] =3D { 1 };)

     

    What is CdePkg and Tor= ito C Library?

    • Cde= Pkg and Torito C Library are a one man show / after work party, that is owned and written solely b= y myself
    • CdePkg is a reference implementation only for Microsoft= C compiler
    • CdePkg is a feasibility study
    • CdePkg is t= he successor of Torito C, based on the same source code
    • CdePkg C= Development Environment is similar to  MdePkg Module Development Envi= ronment

    but guarantees  that the C compiler is always fully usable (all i= ntrinsics available) and the C90/C95 standard library is always available

     

    What are the design go= als?

    • to rewrite the whole thing from scratch, without using any public source c= ode from GNU, BSD, Watcom
    • completeness: full blown C90 + C95 support, as lowest common denominat= or
    • tailored for UEFI: small code size, for UEFI-POST-driver uses a C-Library-= Driver, that contains core/worker functions for realloc() =3D=3D  mal= loc() and free()<= /b>,

    entire printf()-family, entire scanf()-family.

    UEFI-POST-driver just uses small wrapper functions to run the C-Librar= y-Driver code.

    • sta= ble, exact, chipset independent TSC based clock()= with CLOCKS_PER_SEC =3D=3D 1000
    • complete set of the M= icrosoft C-compiler intrinsic functions
    • ROM-able! Runs with stack but w/o any static sto= rage duration in .data segment, e.g. for r= and(), strtok(), tmpfile()

    This is require= d for early PEI before memory sizing, when PEI-images run directly out of f= lash

    • Microsoft (bug) compatible (as far as possible)
      1. use original Microsoft header files for UEFI Shell Apps created in VS2019 =
      2. allow expensive debugging tasks of ANSI C .EFI applications in Visual Stud= io in its Windows NT counter part
      3. to save my lifetime writing a documentation https://github.com/tianocore/edk2-staging/tree/CdePkg/implemented.md#valid= ation-status
    • all the above in one single C-Library CdeLib.lib

     

    CdePkg shall be adjusted to other compilers/tool chains = too, once it is feature-complete and accepted by the UEFI community.

    As long as it is f= or Microsoft VS2019 only.
