| bool "Mali Midgard series support" |
| default y |
| help |
| 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. |
| |
| config MALI_GATOR_SUPPORT |
| bool "Streamline support via Gator" |
| depends on MALI_MIDGARD |
| default y if INSTRUMENTATION_STREAMLINE_OLD |
| 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. |
| |
| config MALI_MIDGARD_DVFS |
| bool "Enable legacy DVFS" |
| depends on MALI_MIDGARD && !MALI_DEVFREQ |
| default n |
| help |
| Choose this option to enable legacy DVFS in the Mali Midgard DDK. |

| config MALI_MIDGARD_ENABLE_TRACE |
| bool "Enable kbase tracing" |
| depends on MALI_MIDGARD |
| default n |
| help |
| Enables tracing in kbase. Trace log available through |
| the "mali_trace" debugfs file, when the CONFIG_DEBUG_FS is enabled |
| |
| config MALI_DEVFREQ |
| bool "devfreq support for Mali" |
| depends on MALI_MIDGARD |
| default y if PLATFORM_JUNO |
| default y if PLATFORM_CUSTOM |
| 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_DMA_FENCE |
| bool "DMA_BUF fence support for Mali" |
| depends on MALI_MIDGARD |
| default n |
| help |
| Support DMA_BUF fences for Mali. |
| |
| This option should only be enabled if the Linux Kernel has built in |
| support for DMA_BUF fences. |

| menuconfig MALI_EXPERT |
| depends on MALI_MIDGARD |
| bool "Enable Expert Settings" |
| default y |
| help |
| Enabling this option and modifying the default settings may produce a driver with performance or |
| other limitations. |

| config MALI_CORESTACK |
| bool "Support controlling power to the GPU core stack" |
| depends on MALI_MIDGARD && MALI_EXPERT |
| 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. |
| |
| If unsure, say N. |
| |
| config MALI_PRFCNT_SET_SECONDARY |
| bool "Use secondary set of performance counters" |
| depends on MALI_MIDGARD && MALI_EXPERT |
| default n |
| 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. |
| |
| If unsure, say N. |
| |
| config MALI_DEBUG |
| bool "Debug build" |

| depends on MALI_MIDGARD && MALI_EXPERT |
| default y if MALI_DEBUG |
| help |
| 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 |
| device attribute, where the timeout is specified in milliseconds. |
| |
| config MALI_ERROR_INJECT |
| bool "Error injection" |
| depends on MALI_MIDGARD && MALI_EXPERT && NO_MALI |

| config MALI_ERROR_INJECT_RANDOM |
| bool "Random error injection" |

| Injected errors are random, rather than user-driven. |

| bool "Enable system event tracing support" |
| depends on MALI_MIDGARD && MALI_EXPERT |
| default n |
| help |
| Choose this option to enable system trace events for each |
| kbase event. This is typically used for debugging but has |
| minimal overhead when not in use. Enable only if you know what |
| you are doing. |

| config MALI_2MB_ALLOC |
| bool "Attempt to allocate 2MB pages" |
| depends on MALI_MIDGARD && MALI_EXPERT |
| default n |
| help |
| Rather than allocating all GPU memory page-by-page, attempt to |
| allocate 2MB pages from the kernel. This reduces TLB pressure and |
| helps to prevent memory fragmentation. |
| |
| If in doubt, say N |

| depends on MALI_MIDGARD && MALI_EXPERT |
| default n |
| help |
| PWRSOFT-765 fixes devfreq cooling devices issues. However, they are |
| not merged in mainline kernel yet. So this define helps to guard those |
| parts of the code. |
