Drew Galbraith 5eb72da9c8 Move glcr::Array & glcr::ArrayView loops to range-based. 2024-01-11 17:39:55 -08:00
Drew Galbraith b2354ae341 Move many loops over glcr::Vector to range-based loops. 2024-01-11 17:13:35 -08:00
Drew Galbraith 8adde27d9b [Zion] Add a thread sleep call. 
For now this can only sleep in increments of the scheduler quantum
(currently 50ms). It also uses a somewhat ineffecient way of tracking
the sleeping threads - it will scale linearly with the number of
sleeping threads.

Drew Galbraith e50d3f8abc [Zion] Remove all capabilities on process cleanup. 2023-11-24 17:05:11 -08:00
Drew Galbraith 2dd69f5844 [Zion] Map user stacks in as regular MemoryObjects. 
This allows us to easily track the physical memory so it
can be freed when the thread exits. It also simplifies the page fault
handler as it just needs to check regular mappings to find a user stack.
