Author: Luis R. Rodriguez <mcgrof@suse.com> Although this driver gives the framebuffer layer a different size for the framebuffer it uses the entire aperture PCI BAR size for the MTRR. Since the framebuffer is included in that range and MTRR was used on the entire PCI BAR WC will have been preferred on that range as …

video: fbdev: radeonfb: use arch_phys_wc_add() and ioremap_wc()
Author: Luis R. Rodriguez <mcgrof@suse.com> Convert the driver from using the x86 specific MTRR code to the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add() will avoid MTRR if write-combining is available, in order to take advantage of that also ensure the ioremap’d area is requested as write-combining. There are a few motivations for this: a) Take advantage of …
