Liav A	90a194377c	Kernel/Graphics: Untie Text mode console from VGACompatibleAdapter class ... Instead, we can construct this type of object without having to instantiate a VGACompatibleAdapter object first. This can help instantiate such console very early on boot to aid debug issues on bare metal hardware.	2022-02-09 21:05:48 +00:00
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
Hendiadyoin1	62f9377656	Kernel: Move special sections into Sections.h ... This also removes a lot of CPU.h includes infavor for Sections.h	2021-06-24 00:38:23 +02:00
Liav A	20743e8aed	Kernel/Graphics + SystemServer: Support text mode properly ... As we removed the support of VBE modesetting that was done by GRUB early on boot, we need to determine if we can modeset the resolution with our drivers, and if not, we should enable text mode and ensure that SystemServer knows about it too. Also, SystemServer should first check if there's a framebuffer device node, which is an indication that text mode was not even if it was requested. Then, if it doesn't find it, it should check what boot_mode argument the user specified (in case it's self-test). This way if we try to use bochs-display device (which is not VGA compatible) and request a text mode, it will not honor the request and will continue with graphical mode. Also try to print critical messages with mininum memory allocations possible. In LibVT, We make the implementation flexible for kernel-specific methods that are implemented in ConsoleImpl class.	2021-05-16 19:58:33 +02:00
