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.
