controller to userspace drivers.

Say Y here to include the memory management driver for the Tegra
GPU, multimedia and display subsystems
config NVMAP_RECLAIM_UNPINNED_VM
bool "Virtualize IOVMM memory in nvmap"
depends on TEGRA_NVMAP && (TEGRA_IOVMM || IOMMU_API)
default y
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 n
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 || IOMMU_API) && HIGHMEM
default n
help
Say Y here to restrict nvmap system memory allocations (both
physical system memory and IOVMM) to just HIGHMEM pages.
config NVMAP_CARVEOUT_KILLER
bool "Reclaim nvmap carveout by killing processes"
depends on TEGRA_NVMAP
default n
help
Say Y here to allow the system to reclaim carveout space by killing
processes. This will kill the largest consumers of lowest priority
first.
config NVMAP_CARVEOUT_COMPACTOR
bool "Compact carveout when it gets fragmented"
depends on TEGRA_NVMAP
default y
help
When carveout allocation attempt fails, compactor defragements
heap and retries the failed allocation.
Say Y here to let nvmap to keep carveout fragmentation under control.
config NVMAP_PAGE_POOLS
bool "Use page pools to reduce allocation overhead"
depends on TEGRA_NVMAP
default y
help
say Y here to reduce the alloction overhead, which is significant
for uncached, writecombine and inner cacheable memories as it
involves changing page attributes during every allocation per page
and flushing cache. Alloc time is reduced by allcoating the pages
ahead and keeping them aside. The reserved pages would be released
when system is low on memory and acquired back during release of
memory.
config NVMAP_PAGE_POOLS_INIT_FILLUP
bool "Fill up page pools during page pools init"
depends on NVMAP_PAGE_POOLS
default y
help
Say Y here to fill up the page pools during page pool init time.
This helps in faster alloctions right from the early alloction
requests. Page pools fill up during init would increase the boot time.
If increase in boot time is not acceptable, keep this option disabled.
config NVMAP_PAGE_POOL_SIZE
hex
default 0x0
config NVMAP_CACHE_MAINT_BY_SET_WAYS
bool "Enable cache maintenance by set/ways"
depends on TEGRA_NVMAP
help
Say Y here to reduce cache maintenance overhead by MVA.
This helps in reducing cache maintenance overhead in the systems,
where inner cache includes only L1. For the systems, where inner cache
includes L1 and L2, keep this option disabled.
config NVMAP_OUTER_CACHE_MAINT_BY_SET_WAYS
bool "Enable outer cache maintenance by set/ways"
depends on TEGRA_NVMAP
help
Say Y here if you want to optimize cache maintenance for ranges
bigger than size of outer cache. This option has no effect on
system without outer cache.
config NVMAP_DEFERRED_CACHE_MAINT
bool "Enable deferred cache maintenance"
depends on TEGRA_NVMAP
help
Say Y here if you want to defer flush requests for
nvmap memory buffer. Cache maintenance of deferred requests
is more efficient since there is a high chance that cache lines
of earlier requests are already flushed. Also, if total size of
deferred ranges is big enough, we flush whole inner or outer
cache.
config NVMAP_VPR
bool "Enable VPR Heap."
depends on TEGRA_NVMAP
default n
help
Say Y here to enable Video Protection Region(VPR) heap.
if unsure, say N.
config NVMAP_FORCE_ZEROED_USER_PAGES
bool "Only alloc zeroed pages for user space"
depends on TEGRA_NVMAP
help
Say Y here to force zeroing of pages allocated for user space. This
avoids leaking kernel secure data to user space. This can add
significant overhead to allocation operations depending on the
allocation size requested.
config TEGRA_DSI
bool "Enable DSI panel."
default n
help
Say Y here to enable the DSI panel.
config NVMAP_CONVERT_CARVEOUT_TO_IOVMM
bool "Convert carveout to IOVMM"

help
Say Y here to force to convert carveout memory requests to
I/O virtual memory requests.
config TEGRA_NVHDCP
bool "Support NVHDCP content protection on HDMI"
default n
help
Say Y here to support NVHDCP upstream and downstream protocols, this
requires a correctly fused chip to negotiate keys.
config TEGRA_HDMI_74MHZ_LIMIT

default n
help
Say Y here to make kernel report only low bandwidth modes.
Useful only for boards which can't deliver 148.50 MHz.
