GPU, multimedia and display subsystems
config NVMAP_RECLAIM_UNPINNED_VM

help
Say Y here to enable nvmap to reclaim I/O virtual memory after
it has been unpinned, and re-use it for other handles. This can
allow a larger virtual I/O VM space than would normally be
supported by the hardware, at a slight cost in performance.
config NVMAP_ALLOW_SYSMEM
bool "Allow physical system memory to be used by nvmap"
depends on TEGRA_NVMAP
default y
help
Say Y here to allow nvmap to use physical system memory (i.e.,
shared with the operating system but not translated through
an IOVMM device) for allocations.
config NVMAP_HIGHMEM_ONLY
bool "Use only HIGHMEM for nvmap"
depends on TEGRA_NVMAP && (NVMAP_ALLOW_SYSMEM || TEGRA_IOVMM) && HIGHMEM
default n
help
Say Y here to restrict nvmap system memory allocations (both
physical system memory and IOVMM) to just HIGHMEM pages.
