MollenOS/Vali is a modern operating system that is built with focus on abstraction and a modular design, allowing anyone to port it to any architecture. It currently targets the x86-32 and x86-64 platform.
Needs to be completed, it enables fsbr, it also disables fsbr on bulk/control done transfers. But it does not handle disabling fsbr on removal of int's
Implement all neccessary syscalls (and there is a lot)
Move modules to have their own process with a event handler (Kill, Restart, etc events it should handle)
Move much of the shared functionality in to a library (fx: the list implementation is needed by drivers, and can't be imported if they run in usermode and list is in kernel mode memory)
Reasonable enough it shuts down the scheduling timer when entering idle thread to avoid rescheduling the idle thread and save resources, however it seems like no interrupts follow as well.. Which is weird since i need interrupts to wakeup the scheduler again. I'm thinking of building a threading log so I can see all thread activity
OHCI uses custom length for isochronous transfers (max of 0x2000 per td instead of MPS)
EHCI uses custom length for pretty much everything (control and bulk can handle between 16k-20k per td) and interrupt/isoc can handle up to 3k per transfer.
USB -> Make sure to add zero-length packets when neccessary
UHCI -> Make sure implementation works
OHCI -> Make sure implementation works
EHCI -> Make sure implementation works
Unicode support is easy enough in the kernel (almost done there), but the challenge is integrating it into the CLIB streamout, which I will have to do.
After we abstracted the virtual memory access we can now completely move ACPICA out to MCore, which means we can reuse it no matter which platform we run MCore on
