#5353: Improve MTRR setup

Reporter: PieterPanman | Owner: axeld

Priority: normal | Milestone: R1
Component: System/Kernel | Version: R1/Development
Keywords: mtrr | Blockedby:
Platform: All | Blocking:

Just so that this isn't forgotten: For my laptop (with vesa), the current
MTRR setup is not able to properly cover the framebuffer. Some people will
probably be stuck with vesa, and there is a huge performance difference if
the MTRR setup covers the framebuffer for vesa.
A better way of achieving this is needed.
See bonefish's [http://dev.haiku-os.org/ticket/5085#comment:4 comment in
#5085].
Refer to #5085 for more information. Right now I just use the workaround
in that bug, which works well.
