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/tianocore/edk2-staging/blob/CdePkg/CdeValidationPk= g/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/SYS= TEM_IF/systeminterfacePEI/main.c#L57

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

  1. = systeminterfaceDXE: https://github.com/tianocore/edk2-staging/blob/CdePkg/CdeValidationPkg/SYS= TEM_IF/systeminterfaceDXE/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.
