Did some UI work and added my compiler/VM to it. Here you can see it running on some real hardware
Don't mind the date/time, the CMOS battery of this machine is dead.

Progress in my quest to get a full toolchain working again under my new libc - binutils builds and appears to be working.

This is amazing. Great progress!

I didn't expect this followup to be so quick, but, gcc:



A lot of weird little things between having gotten it to build at all and successfully getting it to compile something, but it seems to be working and for a large, complex source file.

Finally building a window manager on top of the OS. You can see I'm quite a fan of the old Apple System 6 design .

My sorta slab allocator running for the first time in my old kernel project.
When my new kernel is far enough I will use it there to manage my kernel objects .
I don't have a regular heap atm, the slab just gets a bunch of pages from the physical manager (which just pops them from a stack) and maps them to virtual memory.
I want to avoid having "regular" heap allocations as much as possible (at best not have a kernel heap at all)

EDIT:
The allocator is now able to run on top of my new kernel (microsphere) which had a lot memory-management related stuff added the past days and today.

After a side-track project, I came back and now have a hard drive image that will boot either UEFI or Legacy BIOS.



I was working on this and ran in to a few issues with the actual file image. I was using multiple (custom) utilities to modify the image file and was getting irregular results. Therefore I decided to take a side-track and create a single utility to do what I needed. Once I got the utility to work as I needed, I came back to this dual boot image.

The .zip included in the first URL above contains two images, a floppy image (bootable legacy only) with the LeanFS, and a 10Meg hard drive bootable either UEFI or Legacy. Instructions for QEMU and the UEFI BIOS is included.

New code in my UEFI and Legacy boot/loader code was necessary to allow for each boot technique. I went to update the UEFI source at github but they no longer support older versions of Firefox (WinXP). I will have to boot to a newer version of Windows to simply update it. ( It wasn't broke, why did they fix it!! )

Thanks to all of you whom participate in this hobby of ours.

Cool!

Or you could probably learn a few git commands (e.g. push) to update from command line.

Ya, that too. I will have to go look and see what it takes.

Thanks,

File management.

Now all it needs is an icon grid view :​P

For the record, Linux does the copying filenames as text stuff, but it uses the full path, may want to look into that instead (pretty convenient when something wants a file since I can copy the file with Ctrl+C then paste the name in the file dialog with Ctrl+V - my mouse isn't in great shape and some programs are a bit fincky with drag'n'drop and I'm more of a keyboard shortcut user anyway).

Now i can load dynamically linked libraries and load executables!

Ideally I'd have more interesting file icons at this point. Oh well

I suppose it could be a user-configurable setting. I'll have to think about it.

nakst inspired me to clean up my rebuilt file manager (ported from the older Python implementation), finishing up the icon view and adding selection and double-click navigation.
