Cleanup kernel/CMakeLists.txt 2022-11-19 16:59:39 +00:00			`src/memory/MemoryManager.cpp`
Kernel: Add a heap memory allocator This is the first time I've actually dropped liballoc in favor of writing my own implementation. Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job. But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code! 2022-11-20 14:15:26 +00:00			`src/memory/Heap.cpp`
Add a virtual memory allocator for the kernel 2022-12-05 19:36:24 +00:00			`src/memory/KernelVM.cpp`
kernel: Rename UserVM to AddressSpace This is a more appropriate name now that it does more stuff than allocate virtual memory. To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess. 2023-07-09 18:38:04 +00:00			`src/memory/AddressSpace.cpp`
Use a friendlier way of iterating over the memory map 2022-12-04 14:45:13 +00:00			`src/memory/MemoryMap.cpp`

kernel, libc: Add clock_gettime() 2023-01-06 23:21:08 +00:00			`src/sys/clock_gettime.cpp`

kernel, libc: Add an usleep() system call and use that to implement usleep() and sleep() in libc 2023-01-22 14:00:20 +00:00			`src/sys/usleep.cpp`
kernel+libc: Start interfacing with the VFS from userspace (open & close) This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc. No read/write support, so file descriptors are kind of useless for now. 2023-03-11 16:45:20 +00:00			`src/sys/open.cpp`
kernel: Add an exec() system call Doesn't support arguments or environment for now. 2023-03-16 21:44:58 +00:00			`src/sys/exec.cpp`

kernel+libc: Add a memstat() syscall We can finally show memory usage in userspace. This could have been done using sysfs, but I'm lazy and don't want to implement that. Maybe in the next release? 2023-08-17 18:15:32 +00:00			`src/sys/memstat.cpp`

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 16:59:52 +00:00			`include(debug.cmake)`
