edk2 VS awesome-c

For the modern server/desktop and even laptop, that's also no bad thing. It is somewhat ridiculous that UEFI bioses, internally, still boot in 16-bit real mode and have to do all the steps your bios bootloader used to do to set up a 64-bit environment ready to go: https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a...

Why not just start the CPU in "long mode", which is what everyone is using it for, in the first place?

These newer ARM processors support 32-bit code at EL0 only (userspace). That seems like a reasonable approach for x86 as well and the freebsd announcement has this to say:

> There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.

So for the moment, you can run 32-bit applications just fine.

Download this UEFI shell and place it in the BOOT subfolder

They could have at least informed TianoCore. the affected code in edk2 hasn't been modified in 2 years.... https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Library/BaseBmpSupportLib/BmpSupportLib.c

I have half fixed it.. Using this solution: https://github.com/tianocore/edk2/discussions/4662

You need only EDK2 and some lööps.

What is the difference between this and https://github.com/tianocore/edk2

From there you'll need to get an EFI Shell. There may be one built into your system, but you can also get one here from Tianocore (aka, the people mostly making UEFI). Neither this EFI Shell nor Keytool.efi (the thing you need to load the keys) are signed of course, so you will need to turn off SecureBoot to continue. From there just run Keytool with your new keys, turn back on SecureBoot, and move on with your life.

I had the same issue. What fixed it for me was compiling my own OVMF.fd file from here and using that to boot. The version of OVMF that shipped with fedora was broken for me for some reason.

So, let’s go through an example. Since you’re used to using C, I’d suggest looking through the awesome-C repo. From there, you might decide you’re interested in graphics, so you check out OpenGL.

Awesome C - oz123

You can find a lot of resources at oz123 / awesome-c and this [https://www.linuxquestions.org/questions/programming-9/c-c-tutorials-825748/](C/C++ Tutorials thread).

For example, you can use the C language with sds strings (see https://github.com/antirez/sds) if you want to have an easier time with string formatting and don't want to worry about using the famously unsafe string.h functions correctly. You'll still program in ISO C, but just not in the standard library. The same applies to pretty much all parts of the standard library, the only part unsurpassed is pretty much just printf and the math headers (math.h, fenv.h, tgmath.h, complex.h) imo, and the occasional call to exit. A good place to look for libraries if you want to go that route is the awesome-c collection: https://github.com/oz123/awesome-c

There's an awesome C list of libraries and frameworks [1]. Pick one that suits your needs.

Time and again folks say such and such isn't suitable tool to do something. While some of those admonitions are true, if you're doing something to learn, feel free to ignore those and enjoy your learning. There're folks who learn assembly even today and learn a great deal of other things than assembly and have fun too.

As for C, it'd recommend most folks know the basics since many "modern" languages totally don't teach you those, and in fact hide the details from you that things feel like magic to you eventually if you keep using these high-level languages. This is okay as long as you can know the basics and map them back when needed.
