apio	794567327f	kernel, luna: Port non-VFS changes over from pull request #22 ... OwnedPtr, SharedPtr: Add operator bool Option, Result: Make try_move_value() non-const since it modifies the Option kernel: Switch to a stack we control for the main task as soon as we leave early boot Heap: Fix GPF caused when making many small allocations Heap: Avoid accessing a block after it's potentially deleted luna: Skip UBSAN.cpp in CMakeLists as that's not implemented yet luna: Use spinlocks in the heap implementation kernel, luna: Move Spinlock.h to luna Option: Use __builtin_launder to ensure that the compiler doesn't label this as UB SharedPtr: Implement make_shared using adopt_shared SharedPtr: Delete ptr on failure in all adopt_shared* functions	2023-02-25 17:09:03 +01:00
apio	635437a4a4	luna: Add a new idiomatic way to mark unused parameters as used while keeping their names ... Just call ignore(...)	2023-01-25 21:14:44 +01:00

apio	de04c094e7	x86_64: Skip enabling WP for now until I find how to check for its availability	2023-01-23 20:06:45 +01:00
apio	d5b1d72396	x86_64/MMU: Map the kernel page directory to virtual memory ... This avoids depending on the kernel address space to create a new userspace one, since there is no physical memory access. This was fine for a single process, since its address space was created from the kernel one and no more address spaces were created, but for two or more, this started to become problematic, since we would create one address space while being in another process's address space, which has no direct mapping of physical memory.	2023-01-22 14:46:03 +01:00

apio	1b807a4e06	arch/Timer: Make sure ARCH_TIMER_FREQ is a power of two ... (avoid division and modulo, division is slow) Fortunately, GCC will optimize divisions by powers of two to simple bitwise shifts :)	2023-01-16 19:43:05 +01:00
