Bypass Initialization
The P
ERMEDIA
bypass mechanism gives direct access to memory that
P
ERMEDIA
uses to hold the framebuffer, localbuffer and textures. In some
situations it is useful for an application to have direct access to this
memory without going through the graphics processor. Initialization of
PCI registers, in particular the Bypass Writemask register, covers
initialization of the bypass mechanism.
The writemask register BypassWriteMask is undefined at boot time and
should be set to -1.
Refer to the
TVP4020
Hardware Reference Manual for further details.
