2022-04-01	Everywhere: Run clang-format	Idan Horowitz

2022-01-25	Kernel: Use u64 instead of size_t for File::can_write offset	Idan Horowitz
	This ensures offsets will not be truncated on large files on i686.
2022-01-25	Kernel: Use u64 instead of size_t for File::can_read offset	Idan Horowitz
	This ensures offsets will not be truncated on large files on i686.
2021-11-08	Kernel: Replace KResult and KResultOr<T> with Error and ErrorOr<T>	Andreas Kling
	We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace! This was a slightly tedious refactoring that took a long time, so it's not unlikely that some bugs crept in. Nevertheless, it does pass basic functionality testing, and it's just real nice to finally see the same pattern in all contexts. :^)
2021-10-03	Kernel: Use `operator ""sv` in all class_name() implementations	Brian Gianforcaro
	Previously there was a mix of returning plain strings and returning explicit string views using `operator ""sv`. This change switches them all to standardized on `operator ""sv` as it avoids a call to strlen.
2021-09-18	Kernel: Let MouseDevice and KeyboardDevice write method return EINVAL	Przemysław R. Kusiak
	Currently, writing anything to `/dev/mouse0` or `/dev/keyboard0` causes the Kernel to panic. The reason for this is that `[Mouse,Keyboard]Device::write` always returns 0, which is explicitly prohibited by `VERIFY` macro in `Process::sys$write`. The fix seems trivial; `write` should return EINVAL instead (as is the case with, for example, `KCOVDevice`).
2021-09-08	Kernel/Devices: Remove required_mode and device_name methods	Liav A
	These methods are no longer needed because SystemServer is able to populate the DevFS on its own. Device absolute_path no longer assume a path to the /dev location, because it really should not assume any path to a Device node. Because StorageManagement still needs to know the storage name, we declare a virtual method only for StorageDevices to override, but this technique should really be removed later on.
2021-09-07	Kernel: Rename FileDescription => OpenFileDescription	Andreas Kling
	Dr. POSIX really calls these "open file description", not just "file description", so let's call them exactly that. :^)
2021-09-05	Kernel: Make all Spinlocks use u8 for storage, remove template	Brian Gianforcaro
	The default template argument is only used in one place, and it looks like it was probably just an oversight. The rest of the Kernel code all uses u8 as the type. So lets make that the default and remove the unused template argument, as there doesn't seem to be a reason to allow the size to be customizable.
2021-08-22	Kernel: Rename SpinLock => Spinlock	Andreas Kling

2021-07-11	Kernel: Make various T::class_name() and similar return StringView	Andreas Kling
	Instead of returning char const*, we can also give you a StringView.
2021-07-03	Kernel: Add missing override specifiers	Daniel Bertalan
	The `#pragma GCC diagnostic` part is needed because the class has virtual methods with the same name but different arguments, and Clang tries to warn us that we are not actually overriding anything with these. Weirdly enough, GCC does not seem to care.
2021-05-01	Kernel: Expose minor device numbers for keyboard and mouse	Valtteri Koskivuori
	A fix for two FIXMEs, and paving the way for multi-keyboard/mouse support, I guess.
2021-04-22	Everything: Move to SPDX license identifiers in all files.	Brian Gianforcaro
	SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
2021-04-03	Kernel: Introduce a new HID subsystem	Liav A
	The end goal of this commit is to allow to boot on bare metal with no PS/2 device connected to the system. It turned out that the original code relied on the existence of the PS/2 keyboard, so VirtualConsole called it even though ACPI indicated the there's no i8042 controller on my real machine because I didn't plug any PS/2 device. The code is much more flexible, so adding HID support for other type of hardware (e.g. USB HID) could be much simpler. Briefly describing the change, we have a new singleton called HIDManagement, which is responsible to initialize the i8042 controller if exists, and to enumerate its devices. I also abstracted a bit things, so now every Human interface device is represented with the HIDDevice class. Then, there are 2 types of it - the MouseDevice and KeyboardDevice classes; both are responsible to handle the interface in the DevFS. PS2KeyboardDevice, PS2MouseDevice and VMWareMouseDevice classes are responsible for handling the hardware-specific interface they are assigned to. Therefore, they are inheriting from the IRQHandler class.
