config GK20A
tristate "Nvidia GK20A GPU support"
default y
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
depends on GK20A
prompt "Enable GK20A frequency scaling"
default GK20A_PERFMON
optional
help
Select this entry to enable gk20a scaling
config GK20A_PERFMON
bool "Use Perfmon"
help
Select this to enable built-in perfmon scaling.
The built-in scaling option uses simplistic
scaling mechanism (if busy, increase frequency and
decrease frequency if idle).
config GK20A_DEVFREQ
depends on COMMON_CLK
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 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.
