	help
	  Choose this option if you have an SoC with integrated
	  Nvidia GPU IP.

config GK20A_PMU
	bool "Support GK20A PMU"
	depends on GK20A
	default n
	help
	  Say Y here to enable GK20A PMU features.

choice

	help
	  Select this entry to enable gk20a scaling

config GK20A_DEVFREQ
	depends on COMMON_CLK && PM_DEVFREQ
	bool "Use Devfreq"
	help
	  Select this to use devfreq based scaling.
	  Devfreq is a common framework that allows using
	  variety of different governors and changing
	  between governors on the fly. By default, no
	  governor is selected.

config GK20A_PM_QOS
	depends on GK20A_DEVFREQ
	bool "Use PM_QOS constraints for devfreq based scaling"
	default y
	help
	  Enable support to pass PM_QOS constraints to devfreq based
	  scaling.

config GK20A_RDMA
        bool "Support GK20A RDMA"
        depends on GK20A && MMU_NOTIFIER
        default n
        help
          Say Y here to enable GK20A RDMA features.

config NVGPU_TRACK_MEM_USAGE
        bool "Track the usage of system memory in nvgpu"
	depends on GK20A
	default n
	help
	  Say Y here to allow nvgpu to track and keep statistics on
	  the system memory used by the driver. This does recreate
	  some of the kmem_leak tracking but this is also applicable
	  to other OSes which do not have Linux' kmem_leak.


config GK20A_CYCLE_STATS
	bool "Support GK20A GPU CYCLE STATS"
	depends on GK20A
	default y
	help
	  Say Y here to enable the cycle stats debugging features.

config GK20A_CTXSW_TRACE
	bool "Support GK20A Context Switch tracing"
	depends on GK20A
	default y
	help
	  Enable support for the GK20A Context Switch Tracing. In this mode,
	  FECS collects timestamps for contexts loaded on GR engine. This
	  allows tracking context switches on GR engine, as well as
	  identifying processes that submitted work.

config TEGRA_GK20A_NVHOST
	bool "Support interfacing with nvhost hardware"
	depends on TEGRA_GRHOST || TEGRA_HOST1X
	depends on GK20A
	default y
	help
	  Enable support in GK20A for the nvhost (host1x) dma engine hardware
	  that includes things like hardware syncpts. This requires either
	  TEGRA_GRHOST or TEGRA_HOST1X.

config TEGRA_GK20A
	bool "Enable the GK20A GPU on Tegra"
	depends on GK20A
	default y
	help
	  Enable support for the GK20A graphics engine on Tegra
	  by adding a Tegra platfrom interface to the GK20A driver.

config TEGRA_ACR
	bool "Enable HS bin support on GM20B GPU on Tegra"
	depends on GK20A && GK20A_PMU
	default n
	help
	  Enable Support for Loading High Secure binary, and using
	  Write Protected Regions (WPR) for storing ucodes, and bootstrap
	  PMU, FECS and GPCCS in Low Secure mode.

config TEGRA_USE_NA_GPCPLL
	bool "Enable noise aware mode of GM20B GPCPLL on Tegra"
	depends on GK20A
	depends on COMMON_CLK
	default n
	help
	  Enable noise aware (NA) mode of GM20b GPCPLL. In this mode PLL output
	  frequency is automatically adjusted when GM20b voltage is fluctuating
	  because of transient PMIC or power distribution tree noise.

config GK20A_PCI
	bool "Support PCIe NVIDIA GPUs on nvgpu"
	depends on PCI && GK20A
	default y
	help
	  Enable support for GPUs on PCIe bus.

config GK20A_TRACE_PRINTK
	bool "Support trace_printk debugging"
	depends on GK20A && TRACING
	default n
	help
	  Enable nvgpu debug facility to redirect debug spew to ftrace. This
	  affects kernel memory use, so should not be enabled by default.

config GK20A_VIDMEM
	bool "Support separate video memory on nvgpu"
	depends on GK20A
	default n
	help
	  Enable support for using and allocating buffers in a distinct video
	  memory aperture (in contrast to general system memory), available on
	  GPUs that have their own banks. PCIe GPUs have this, for example.

config NVGPU_SUPPORT_CDE
	bool "Support extraction of comptags for CDE"
	depends on GK20A
	default y
	help
	  Enable support for extraction of comptags for CDE.

config NVGPU_USE_TEGRA_ALLOC_FD
	bool "Use tegra_alloc_fd() for allocating dma_buf fds for vidmem"
	depends on GK20A && GK20A_VIDMEM
	default y
	help
	  Use tegra_alloc_fd() for allocating dma_buf fds. This allocates
	  the fds above 1024 which exempts them from counting against process
	  fd limit.

	  It is only available in Tegra kernel.
