help
Driver for the Tegra graphics host hardware.
config TEGRA_DC
tristate "Tegra Display Contoller"
depends on ARCH_TEGRA && TEGRA_GRHOST
select FB_MODE_HELPERS
select I2C
help
Tegra display controller support.
config TEGRA_OVERLAY
tristate "Tegra Overlay Device Node"
depends on TEGRA_DC && !TEGRA_DC_EXTENSIONS
help
Device node for multi-client overlay support.

help
Framebuffer device support for the Tegra display controller.
config TEGRA_DC_EXTENSIONS
bool "Tegra Display Controller Extensions"
depends on TEGRA_DC
default y
help
This exposes support for extended capabilities of the Tegra display
controller to userspace drivers.
config TEGRA_NVMAP
bool "Tegra GPU memory management driver (nvmap)"
default y
help
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
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 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.
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_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 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"
depends on TEGRA_NVMAP && TEGRA_IOVMM_SMMU
default y
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
bool "Support only up to 74.25 MHz HDMI pixel frequency"
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.
