Andreas Kling	75564b4a5f	Kernel: Make kernel region allocators return KResultOr<NOP<Region>> ... This expands the reach of error propagation greatly throughout the kernel. Sadly, it also exposes the fact that we're allocating (and doing other fallible things) in constructors all over the place. This patch doesn't attempt to address that of course. That's work for our future selves.	2021-09-06 01:55:27 +02:00
Liav A	ed6c1f53af	Kernel/VirtIO: Defer initialization of device out of the constructor ... This ensures we safely handle interrupts (which can call virtual functions), so they don't happen in the constructor - this pattern can lead to a crash, if we are still in the constructor context because not all methods are available for usage (some are pure virtual, so it's possible to call __cxa_pure_virtual). Also, under some conditions like adding a PCI device via PCI-passthrough mechanism in QEMU, it became exposed to the eye that the code asserts on RNG::handle_device_config_change(). That device has no configuration but if the hypervisor still misbehaves and tries to configure it, we should simply return false to indicate nothing happened.	2021-09-04 16:36:02 +02:00

Liav A	8e90a4fd1c	Kernel/VirtIO: Don't expose constructors as public method ... This leads to a bad pattern where anyone could create an RNG or a Console object. Instead, let's just use the common pattern of a static method to instantiate a new object and return it wrapped by a NonnullRefPtr.	2021-08-31 16:51:13 +02:00
Liav A	01ae614727	Kernel/VirtIO: Remove redundant VirtIO word from filenames ... Now that all related VirtIO classes are in the VirtIO namespace, let's just remove the redundant VirtIO word from filenames.	2021-08-31 16:51:13 +02:00
