Furthermore the ANSI C Interface is disseminated widely, also it=92s bugs = and pitfalls are known very well by a broad range of IT professionals and may help to be better supportable= by the open source initiative compared to the proprietary interface that is available today in Tianocore= UEFI. Now 9 new ANSI C functions tmpnam(), printf(), snprintf(), sprintf(), vsnp= rintf(), vsscanf(), sscanf(), vprintf(), vsprintf() are introduced for PEI and DXE. Currently there are 8 examples implemented: 1. argvc: https://github.com/tianocore/edk2-staging/blob/CdePkg/CdeVali= dationPkg/HOSTED_ENV/argcv/main.c#L57 argc/argv handling according to https://msdn.microsoft.com/en-us/library/a= 1y7w461.aspx 1. systeminterfacePEI: https://github.com/tianocore/edk2-staging/blob/C= dePkg/CdeValidationPkg/SYSTEM_IF/systeminterfacePEI/main.c#L57 demonstration, how PeiServices and FileHandle are passed into main() 1. systeminterfaceDXE: https://github.com/tianocore/edk2-staging/blob/C= dePkg/CdeValidationPkg/SYSTEM_IF/systeminterfaceDXE/main.c#L57 demonstration, how SystemTable and ImageHandle are passed into main() ANSI C LIBRARY functions: 1. time.h clock(): https://github.com/tianocore/edk2-staging/blob/CdePk= g/CdeValidationPkg/TIME_H/clock/main.c#L1 for PEI and DXE phase.

Some time ago I decided 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 the library (=93CdeLib=94) is not yet fully tested. I will be demonstrating my verification procedure in the upcoming weeks on= EDK2 STAGING https://github.com/tianocore/edk2-staging/tree/CdePkg Currently there are 3 examples implemented: 1. argvc: https://github.com/tianocore/edk2-staging/blob/CdePkg/CdeVali= dationPkg/HOSTED_ENV/argcv/main.c#L57 argc/argv handling according to https://msdn.microsoft.com/en-us/library/a= 1y7w461.aspx 1. systeminterfacePEI: https://github.com/tianocore/edk2-staging/blob/C= dePkg/CdeValidationPkg/SYSTEM_IF/systeminterfacePEI/main.c#L57 demonstration, how PeiServices and FileHandle are passed into main() 1. systeminterfaceDXE: https://github.com/tianocore/edk2-staging/blob/C= dePkg/CdeValidationPkg/SYSTEM_IF/systeminterfaceDXE/main.c#L57 demonstration, how SystemTable and ImageHandle are passed into main() Upcoming next demonstration will be the clock() function end of this week The idea is to bring the ANSI C Library interface into POST drivers. This will: 1. ease porting tasks 2. allow cross development 3. allow developers to focus on their aims, because they aren=92t force= d to keep in mind a lot of additional info (e.g. RShiftU64) 4. provide all intrisics to allow the compiler to be a =93C compiler=94 (e.g. char buffer[256] =3D { 1 };) What is CdePkg and Torito C Library? * CdePkg and Torito C Library are a one man show / after work party, t= hat is owned and written solely by myself * CdePkg is a reference implementation only for Microsoft C compiler * CdePkg is a feasibility study * CdePkg is the successor of Torito C, based on the same source code * CdePkg C Development Environment is similar to MdePkg Module Develo= pment Environment but guarantees that the C compiler is always fully usable (all intrinsics= available) and the C90/C95 standard library is always available What are the design goals? * to rewrite the whole thing from scratch, without using any public so= urce code from GNU, BSD, Watcom * completeness: full blown C90 + C95 support, as lowest common denomin= ator * tailored for UEFI: small code size, for UEFI-POST-driver uses a C-Li= brary-Driver, that contains core/worker functions for realloc() =3D=3D mal= loc() and free(), entire printf()-family, entire scanf()-family.

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 9 new ANSI C functi= ons t= mpnam(), printf(), snprintf(), sprintf(), vsnprintf(), vsscanf(), sscanf(),= vprintf(), vsprintf()

are introduced for P= EI and DXE.

 

Currently there are 8= 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()

 

ANSI C LIBRA= RY functions:

  1. time.h clock(): https://github.com/tianocore/edk2-st= aging/blob/CdePkg/CdeValidationPkg/TIME_H/clock/main.c#L1

for PEI and DXE phase. It provides TSC based= , millisecond precise, exact and chipset independent clock() = function.

NOTE: in em= ulation mode the TSC nominal frequency is supposed to be 1GHz

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.
