REMARKS:
|
|
This enumeration defines the type values passed to the PM_agpReservePhysical
|
|
function, to define how the physical memory mapping should be handled.
|
|
|
|
The PM_agpUncached type indicates that the memory should be allocated as
|
|
uncached memory.
|
|
|
|
The PM_agpWriteCombine type indicates that write combining should be enabled
|
|
for physical memory mapping. This is used for framebuffer write combing and
|
|
speeds up direct framebuffer writes to the memory.
|
|
|
|
The PM_agpIntelDCACHE type indicates that memory should come from the Intel
|
|
i81x Display Cache (or DCACHE) memory pool. This flag is specific to the
|
|
Intel i810 and i815 controllers, and should not be passed for any other
|
|
controller type.
