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_DEFAULT_TIMEOUT
depends on GK20A
int "Default timeout for submits"
default 10000
help
Default timeout for jobs in milliseconds. Set to zero for no timeout.
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 TEGRA_CLK_FRAMEWORK
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_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 TEGRA_GK20A
bool "Enable the GK20A GPU on Tegra"
depends on TEGRA_GRHOST
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.
The Tegra platform interface requires TEGRA_GRHOST (host1x).
config TEGRA_ACR
bool "Enable HS bin support on GM20B GPU on Tegra"
depends on 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 TEGRA_CLK_FRAMEWORK
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.
