Guilherme Goncalves	33b78915d3	Kernel: Propagate overflow errors from Memory::page_round_up ... Fixes #11402.	2021-12-28 23:08:50 +01:00
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
Andreas Kling	2cd8b21974	Kernel: Add convenience values to the Memory::Region::Access enum ... Instead of `Memory::Region::Access::Read | Memory::Region::AccessWrite` you can now say `Memory::Region::Access::ReadWrite`.	2021-08-06 22:25:00 +02:00
Andreas Kling	93d98d4976	Kernel: Move Kernel/Memory/ code into Kernel::Memory namespace	2021-08-06 14:05:58 +02:00
Sahan Fernando	34e9fa4d3b	Kernel: Abstract FramebufferConsole away from contiguous physical range ... Currently, Kernel::Graphics::FramebufferConsole is written assuming that the underlying framebuffer memory exists in physically contiguous memory. There are a bunch of framebuffer devices that would need to use the components of FramebufferConsole (in particular access to the kernel bitmap font rendering logic). To reduce code duplication, framebuffer console has been split into two parts, the abstract GenericFramebufferConsole class which does the rendering, and the ContiguousFramebufferConsole class which contains all logic related to managing the underling vm object. Also, a new flush method has been added to the class, to support devices that require an extra flush step to render.	2021-06-25 19:26:30 +02:00
