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.

This enables support for Mali-450 specific features.

This enabled extra debug checks and messages in the Mali driver.

This enables gator profiling of Mali GPU events.

This enables the internal legacy Mali profiling API.

This enables support for the UMP memory sharing API in the Mali driver.

bool "Enable Mali dynamically frequency change"

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.

|
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

This forces the Mali driver to never print any messages.

If unsure, say N.
