apio	0e607c2fef	Bitmap: Declare more variables as const ... I miss Rust's immutability-by-default...	2023-01-21 23:04:21 +01:00
apio	a3d0fa7d0a	UserVM: Validate the entire range when freeing multiple VM pages	2023-01-16 21:16:38 +01:00
apio	09dc8bd522	Bitmap: Add find_region() and find_and_toggle_region()	2023-01-13 18:55:31 +01:00
apio	84c82a4e75	luna, kernel: More constness	2023-01-10 19:31:41 +01:00
apio	c83f6c03b5	Bitmap: Add a 'find_and_toggle' method ... Just like find(), but toggles the value when finding it. Avoids doing this manually in MemoryManager and KernelVM.	2023-01-09 18:08:50 +01:00
apio	4287ec6cb0	Bitmap: Introduce a new method 'find' and use it in MM and KernelVM ... This method looks for the first bit with a value, optionally from a starting index, and returns its index. This should be (haven't benchmarked) way faster than the manual way, AKA what MM and KernelVM were doing. This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)	2023-01-09 17:59:52 +01:00

apio	59765aa334	Rename String.h -> CString.h ... Let's not confuse String.h with a managed string class, it's in fact the equivalent of the C stdlib's <string.h>	2022-12-16 20:40:04 +01:00
