| Enable this option to build support for a ARM Mali Midgard GPU. |

| To compile this driver as a module, choose M here: |
| this will generate a single module, called mali_kbase. |

| default n |
| help |
| Adds diagnostic support for use with the ARM Streamline Performance Analyzer. |
| 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. |

| default n |
| help |
| 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. |

| help |
| Select this option to use secondary set of performance counters. Kernel |
| features that depend on an access to the primary set of counters may |
| become unavailable. Enabling this option will prevent power management |
| from working optimally and may cause instrumentation tools to return |
| bogus results. |

| 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. |

| 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. |

| 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. |
| |
| If in doubt, say N. |
