35 hoursusr: mrow: Use 'libgfx' instead of bare fbdevIan Moffett
Instead of relying on mmap()'ing the framebuffer and doing shape math manually, this commit puts libgfx to use. Signed-off-by: Ian Moffett <ian@osmora.org>
35 hourslib: Introduce libgfxIan Moffett
This commit introduces libgfx which is a low-level graphics library and does not know anything about windows, display architecture, etc. The job of libgfx is soley to provide an API to draw shapes, graphical objects and perform operations on them. Signed-off-by: Ian Moffett <ian@osmora.org>

8 dayskernel: vsr: Add 'td' argument for most funcsIan Moffett
Allow specification of which process should be targeted for specific operations. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: Introduce initial VSR implIan Moffett
This commit introduces the initial implementation of Virtual System Resources (VSRs). Virtual system resources enable specific subsystems to control global state while the VSR acts as a middle man between the process, and the actual resource itself. This allows the products of certain operations to be routed to either the global state or a local (per-process) "shallow copy" whose data and side effects are only visible through that process. An example of something this would be useful for is some sort of transparent access control mechanism where if a process should not modify global system-wide state, it can at least modify the state for itself.
