trying to write about x86_64 (uefi, aslr, message signaled interrupts, lapic, acpi, iommu etc. etc.) and how to do platform init etc. to get ready for OS to execute. its a mess. its also hard to find someone who can proof read it and give meaningful feedback. (not many ppl enjoy this stuff i suppose :()
It is hard, and things are messy in some areas. But in my experience it’s less hard than writing a lot of the existing documentation would’ve been (because good datasheets and documentation are more available now) and actually less messy (with some exceptions) than things were back in the days of the legacy hardware most existing wikis etc focus on.
Finding people with the knowledge, time and willingness to proof-read is also hard - but surely not insurmountable if we collectively decide it’s an endeavour we want to pursue.
