Hi UEFI community,
I’d like to introduce the CdePkg to edk2-staging.
The package is not yet completed but ready to demonstrate it’s power, probably
also for modernFW.
A couple of years ago, after an UEFI BIOS project on AMD platform I decided to
write my own ANSI C Library for UEFI Shell and POST.
My design goals were:
1. to rewrite the whole thing from scratch, without using any public source
code from GNU, BSD, Watcom or Intel EDK2 / tiano core
2. completeness: full blown C90 + C95 support, no C99, no non-specified
extensions at all , e.g. itoa(), stricmp()...
3. small code size, for UEFI-POST-driver uses a C-Library-Driver, that
contains core/worker functions for realloc() == malloc() and free(),
entire printf-family, entire scanf-family.
UEFI-POST-driver just uses small wrapper functions to run the C-Library-Driver
code.
1. stable, exact, chipset independent (w/o ACPI timer) "clock()” with
CLOCKS_PER_SEC == 1000
2. complete set of the Microsoft C-compiler intrinsic functions
3. ROM-able! Runs with stack but w/o any static storage duration in .data
segment, e.g. for rand(), strtok(), tmpfile()
This is required for early PEI before memory sizing, when PEI-images run
directly out of flash.
1. Microsoft bug compatible (as far as possible)
* to save my lifetime writing a documentation
https://github.com/JoaquinConoBolillo/torito-C-Library/blob/master/implemented.md
* use original Microsoft header files for UEFI Shell Apps created in
VS2017/19
* “debug”-mode for UEFI Shell executable in VS2017/19, that truly runs
on Windows (that works
when using library functions only, no HW access, not UEFI-API use) to debug the
library
itself – but this just links the same .OBJ module with the WinNT-EntryPoint
instead of UEFI-EntryPoint
(The entry point module pulls in the appropriate OS-interface branch dispatcher)
1. all that in one single C-Library CdeLib.lib
The Readme.MD is here: https://github.com/MinnowWare/CdePkg#cdepkg
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 for Microsoft VS2017/19 only.
The CdePkg is integrated into the “vUDK2018”-EDK2, which in turn runs in a
MinnowBoard build.
It can be emulated in the Nt32Pkg, since EmulatorPkg in “vUDK2018” doesn’t
support Windows…
I would like to move the “vUDK2018”-EDK2 to the edk2-staging branch CdePkg, but
need to have access granted.
Can anyone kindly grant access rights to me?
Best Regards,
Kilian
