config MALI400
	tristate "Mali-300/400/450 support"
	depends on ARM || ARM64
	select DMA_SHARED_BUFFER
	help
	  This enables support for the ARM Mali-300, Mali-400, and Mali-450
	  GPUs.

	  To compile this driver as a module, choose M here: the module will be
	  called mali.

config MALI450
	bool "Enable Mali-450 support"
	depends on MALI400
	help
	  This enables support for Mali-450 specific features.

config MALI470
	bool "Enable Mali-470 support"
	depends on MALI400
	help
	  This enables support for Mali-470 specific features.

config MALI400_DEBUG
	bool "Enable debug in Mali driver"
	depends on MALI400
	help
	  This enabled extra debug checks and messages in the Mali driver.

config MALI400_PROFILING
	bool "Enable Mali profiling"
	depends on MALI400
	select TRACEPOINTS
	default y
	help
	  This enables gator profiling of Mali GPU events.

config MALI400_INTERNAL_PROFILING
	bool "Enable internal Mali profiling API"
	depends on MALI400_PROFILING
	default n
	help
	  This enables the internal legacy Mali profiling API.

config MALI400_UMP
	bool "Enable UMP support"
	depends on MALI400
	help
	  This enables support for the UMP memory sharing API in the Mali driver.

config MALI_DVFS
	bool "Enable Mali dynamically frequency change"
	depends on MALI400 && !MALI_DEVFREQ
	default y
	help
	  This enables support for dynamic change frequency of Mali with the goal of lowering power consumption.

config MALI_DMA_BUF_MAP_ON_ATTACH
	bool "Map dma-buf attachments on attach"
	depends on MALI400 && DMA_SHARED_BUFFER
	default y
	help
	  This makes the Mali driver map dma-buf attachments after doing
	  attach. If this is not set the dma-buf attachments will be mapped for
	  every time the GPU need to access the buffer.

	  Mapping for each access can cause lower performance.

config MALI_SHARED_INTERRUPTS
	bool "Support for shared interrupts"
	depends on MALI400
	default n
	help
	  Adds functionality required to properly support shared interrupts.  Without this support,
	  the device driver will fail during insmod if it detects shared interrupts.  This also
	  works when the GPU is not using shared interrupts, but might have a slight performance
	  impact.

config MALI_PMU_PARALLEL_POWER_UP
	bool "Power up Mali PMU domains in parallel"
	depends on MALI400
	default n
	help
	  This makes the Mali driver power up all PMU power domains in parallel, instead of
	  powering up domains one by one, with a slight delay in between. Powering on all power
	  domains at the same time may cause peak currents higher than what some systems can handle.
	  These systems must not enable this option.

config MALI_DT
	bool "Using device tree to initialize module"
	depends on MALI400 && OF
	default n
	help
	  This enable the Mali driver to choose the device tree path to get platform resoures
	  and disable the old config method. Mali driver could run on the platform which the
	  device tree is enabled in kernel and corresponding hardware description is implemented
	  properly in device DTS file.

config MALI_DEVFREQ
	bool "Using devfreq to tuning frequency"
	depends on MALI400 && PM_DEVFREQ
	select DEVFREQ_GOV_SIMPLE_ONDEMAND
	default n
	help
	Support devfreq for Mali.

	Using the devfreq framework and, by default, the simpleondemand
	governor, the frequency of Mali will be dynamically selected from the
	available OPPs.

config MALI_QUIET
	bool "Make Mali driver very quiet"
	depends on MALI400 && !MALI400_DEBUG
	default n
	help
	  This forces the Mali driver to never print any messages.

	  If unsure, say N.
