this will generate a single module, called mali_kbase.

You will need the Gator device driver already loaded before loading this driver when enabling

Streamline debug support.

This is a legacy interface required by older versions of Streamline.

Enabling this feature on supported GPUs will let the driver powering

on/off the GPU core stack independently without involving the Power

Domain Controller. This should only be enabled on platforms which

integration of the PDC to the Mali GPU is known to be problematic.

This feature is currently only supported on t-Six and t-HEx GPUs.

Select this option to use secondary set of performance counters. Kernel

When you start to work with the Mali Midgard series device driver the platform-specific code of

Select this option to use Device Tree with the Mali driver.

When using this option the Mali driver will get the details of the

GPU hardware from the Device Tree. This means that the same driver

binary can run on multiple platforms as long as all the GPU hardware
|
details are described in the device tree.

Device Tree is the recommended method for the Mali driver platform

integration.

Select this option to enable additional checking and reporting on the

use of sync fences in the Mali driver.

This will add a 3s timeout to all sync fence waits in the Mali

driver, so that when work for Mali has been waiting on a sync fence
|
for a long time a debug message will be printed, detailing what fence
|
is causing the block, and which dependent Mali atoms are blocked as a

result of this.

The timeout can be changed at runtime through the js_soft_timeout

This can be used to test the driver in a simulated environment

present it will not be used. This can be used to test the majority of the

Use AArch64 format page tables for the GPU instead of LPAE-style.
|
The two formats have the same functionality and performance but a
|
future GPU may deprecate or remove the legacy LPAE-style format.
|
|
The LPAE-style format is supported on all Midgard and current Bifrost
|
GPUs. Enabling AArch64 format restricts the driver to only supporting

Bifrost GPUs.
