- Remove some magic numbers
- Remove some duplicate branches
- Reduce the amount of casting between u8* and u32*
- Some renaming of confusing variables
This in turn makes the built-in kernel console much more nicer to look
into, so let's remove the support for 8x8 bitmap and instead add 8x16
font bitmap.
Instead of winging it with "width * 4", use the actual pitch since it
may be different.
This makes the kernel text console show up in native 1368x768 on my
ThinkPad X250. :^)
The GenericFramebufferConsoleImpl class implements the logic without
taking into account any other details such as synchronization. The
GenericFramebufferConsole class then is a simple wrapper around
GenericFramebufferConsoleImpl that takes care of synchronization.
This allows us to re-use this implementation with e.g. different
synchronization schemes.
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.
