GPU, multimedia and display subsystems
config NVMAP_HIGHMEM_ONLY

Say Y here to restrict nvmap system memory allocations (both
physical system memory and IOVMM) to just HIGHMEM pages.
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_POOL_DEBUG
bool "Debugging for page pools"
depends on NVMAP_PAGE_POOLS
help
Say Y here to include some debugging info in the page pools. This
adds a bit of unnecessary overhead so only enable this is you
suspect there is an issue with the nvmap page pools.
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_CACHE_MAINT_BY_SET_WAYS

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_CACHE_MAINT_BY_SET_WAYS_ON_ONE_CPU
bool "Perform cache maint on one cpu only"
depends on TEGRA_NVMAP && NVMAP_CACHE_MAINT_BY_SET_WAYS
help
Say Y here to avoid cache maint on all CPU's during inner cache maint
by set/ways. When L1 and L2 are inner caches, cache maint on one
CPU is enough. When L1 is inner and L2 is outer, cache maint on
all CPU's is necessary during L1 cache maint by set/ways.
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_DMABUF_STASH
bool "Enable stashing of IOVA maps with dmabuf"
depends on TEGRA_NVMAP
default y
help
Set to Y if you would like nvmap to stash maps when using dma
bufs. This will speed up remapping of the same handle at the cost
of using more IOVA space.
config NVMAP_DMABUF_STASH_STATS
bool "Enable stat tracking on the stash"
depends on NVMAP_DMABUF_STASH
help
Say Y to enable tracking of basic cache statistics on the dmabuf
stash. This adds some overhead but should be very useful for
debugging memory leaks.
config NVMAP_FORCE_ZEROED_USER_PAGES
bool "Only alloc zeroed pages for user space"
depends on TEGRA_NVMAP
default y
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 NVMAP_USE_CMA_FOR_CARVEOUT
bool "Use CMA memory for carveouts"
depends on TEGRA_NVMAP
help
Say Y here to reserve carveout memory using CMA
API. CMA reserved memory can be used by applications
when it is not in use by the device that reserved it.
config NVMAP_FD_START
hex "FD number to start allocation from"
depends on TEGRA_NVMAP
default 0x400
help
NvMap handles are represented with FD's in the user processes.
To avoid Linux FD usage limitations, NvMap allocates FD starting
from this number.
config NVMAP_DEFER_FD_RECYCLE
bool "Defer FD recycle"
depends on TEGRA_NVMAP
help
Say Y here to enable deferred FD recycle.
A released nvmap handle would release memory and FD. This FD
can be reused immediately for subsequent nvmap allocation req in
the same process. Any buggy code in client process that continues to
use FD of released allocation would continue to use new allocation
and can lead to undesired consequences, which can be hard to debug.
Enabling this option would defer recycling FD for longer time and
allows debugging incorrect FD references by clients by returning errors
for the accesses that occur after handle/FD release.
config NVMAP_DEFER_FD_RECYCLE_MAX_FD
hex "FD number to start free FD recycle"
depends on NVMAP_DEFER_FD_RECYCLE
default 0x8000

Once last allocated FD reaches this number, allocation of subsequent
FD's start from NVMAP_START_FD.
