Hi Maciej, I have updated and fixed build errors in branch CdePkg (https://github.com/tianocore/edk2-staging.git).
Also a POST trace is recorded on my MinnowBoard and stored here: https://raw.githubusercontent.com/tianocore/edk2-staging/CdePkg/UEFIBinaries/RELEASE.log All implemented Standard-C-functions from CdePkg/Torito C Library demonstrates its basic behavior. There are also a lot of WCHAR.H- and WCTYPE.H-functions. For the wide-functions I just perform the characters 0..0x1FF instead of all 65536 different wchar_t characters due to runtime regards… Regrettably the MinnowBoard is deprecated https://www.silicom-usa.com/pr/eol/minnowboard-turbot<https://www.silicom-usa.com/pr/eol/minnowboard-turbot/> but the CdePkg also runs in the EMULATOR: https://github.com/tianocore/edk2-staging/tree/CdePkg#howto Best Regards, Kilian From: Kilian Kegel<mailto:kilian_ke...@outlook.com> Sent: Thursday, August 5, 2021 06:14 AM To: devel@edk2.groups.io<mailto:devel@edk2.groups.io>; af...@apple.com<mailto:af...@apple.com>; Leif Lindholm<mailto:l...@nuviainc.com> Cc: Rebecca Cran<mailto:rebe...@nuviainc.com>; tim.le...@insyde.com<mailto:tim.le...@insyde.com>; maciej.rab...@linux.intel.com<mailto:maciej.rab...@linux.intel.com>; Mike Kinney<mailto:michael.d.kin...@intel.com> Subject: Re: [edk2-devel] "StdLibPkg" branch on edk2-staging Hi all, I plan to come back with the https://github.com/tianocore/edk2-staging/tree/CdePkg end of this year and to unroll the source code of fundamental parts of my C Library and discuss that along the 30. anniversary of “The C Book” https://publications.gbdirect.co.uk/c_book/chapter9 Additionally I will discuss the details you need to know: 1. about the differences C90/C95/C99 in language and library 2. how to get HOSTED ENVIRONMENT for UEFI POST drivers 3. how to get Intel/AMD TimeStampCounter based precise time calibration - platform, processor and chipset independent for x86 UEFI platforms 1. how to arrange space optimization for UEFI FW as an embedded platform 2. how to test and verify the compatibility of a Standard C Library implementation, since “CI“ won’t help at all in this regards 1. how to implement a printf-core that performs narrow and wide mode at once for space optimization 2. how to implement a scanf-core that performs narrow and wide mode at once for space optimization 3. how to implement realloc() sub-allocator on UEFI memory management functions for PEI and DXE Note: If UEFI is going to provide Standard-C-Functions for all drivers, you will have soon e.g. “sprintf()” in all drivers. The amount of code for a proper sprintf() + scanf() + wscanf() + strtok() + wcstok() + malloc() … implementation that is not tailored for embedded FW, will overrun the BIOS FLASH space instantly. I consider commercial BIOS implementations that runs really many drivers (> 100) to start a platform. Currently I implement more feature to CdePkg/Torito C Library: 1. Improve UEFI driver cross development for VisualStudio and EDK2 2. substitution of “DEBUG” traces by CdePkg-traces that allows usage of predefined DEBUG-messages to run in a CdePkg-based driver. Sole purpose is to have DEBUG/RELEASE mode _NOT_ globally, but locally to get trace messages selectively for specific drivers only. (to speed up POST with traces, that consumes a significant amount of time during working hours of a BIOS developer) 1. add SMM support. Shell, DXE, PEI (pre and post memory) is already available for 2 years: https://edk2.groups.io/g/devel/message/51562?p=,,,20,0,0,0::Created,,CdePkg,20,2,0,65191785 1. get ACPICA tools https://acpica.org/ to UEFI Shell I need to implement some non-standard / Microsoft specific C functions to get that running for Andrew Fish. That time links from https://github.com/KilianKegel are under construction and are not necessarily up-to-date. Same for https://github.com/tianocore/edk2-staging/tree/CdePkg that is not used for long … But https://github.com/KilianKegel/CdePkg.git driver set and sample set runs instantly on the latest BIOS of a commercial vendor on a Intel IOTG TGL-H (Tiger Lake H) board using the Microsoft build environment. @Tim: I’d really appreciate if CdePkg could hold additionally Insyde BIOS support. Regrettably I do not have access to Insyde source code. @Maciej I can not see any “wide” functions here. https://github.com/DevSolar/pdclib<https://github.com/DevSolar/pdclib%20from%20WCHAR.H> from WCHAR.H or WCTYPE.H. That is a serious limitation in the UEFI environment. To create UEFI-Shell programs for Personal Computers this link can be used. https://github.com/KilianKegel/Visual-ANSI-C-for-UEFI-Shell#visual-ansi-c-for-uefi-shell Best regards, Kilian From: Andrew Fish via groups.io<mailto:afish=apple....@groups.io> Sent: Thursday, August 5, 2021 05:35 AM To: edk2-devel-groups-io<mailto:devel@edk2.groups.io>; Leif Lindholm<mailto:l...@nuviainc.com> Cc: Rebecca Cran<mailto:rebe...@nuviainc.com>; tim.le...@insyde.com<mailto:tim.le...@insyde.com>; maciej.rab...@linux.intel.com<mailto:maciej.rab...@linux.intel.com>; Mike Kinney<mailto:michael.d.kin...@intel.com> Subject: Re: [edk2-devel] "StdLibPkg" branch on edk2-staging I’d guess I’d also ask the why not NewLib?
