menuconfig MALI_MIDGARD
tristate "Mali Midgard series support"
select GPU_TRACEPOINTS if ANDROID
default n
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 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 && !MALI_PLATFORM_DEVICETREE
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 && PM_DEVFREQ
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 && !KDS
default n
help
Support DMA_BUF fences for Mali.
This option should only be enabled if KDS is not present and
the Linux Kernel has built in support for DMA_BUF fences.
# MALI_EXPERT configuration options
menuconfig MALI_EXPERT
depends on MALI_MIDGARD
bool "Enable Expert Settings"
default n
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_PLATFORM_FAKE
bool "Enable fake platform device support"
depends on MALI_MIDGARD && MALI_EXPERT
default n
help
When you start to work with the Mali Midgard series device driver the platform-specific code of
the Linux kernel for your platform may not be complete. In this situation the kernel device driver
supports creating the platform device outside of the Linux platform-specific code.
Enable this option if would like to use a platform device configuration from within the device driver.
choice
prompt "Platform configuration"
depends on MALI_MIDGARD && MALI_EXPERT
default MALI_PLATFORM_DEVICETREE
help
Select the SOC platform that contains a Mali Midgard GPU
config MALI_PLATFORM_DEVICETREE
bool "Device Tree platform"
depends on OF
help
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.
config MALI_PLATFORM_VEXPRESS
depends on ARCH_VEXPRESS && (ARCH_VEXPRESS_CA9X4 || ARCH_VEXPRESS_CA15X4)
bool "Versatile Express"
config MALI_PLATFORM_VEXPRESS_VIRTEX7_40MHZ
depends on ARCH_VEXPRESS && (ARCH_VEXPRESS_CA9X4 || ARCH_VEXPRESS_CA15X4)
bool "Versatile Express w/Virtex7 @ 40Mhz"
config MALI_PLATFORM_GOLDFISH

bool "Android Goldfish virtual CPU"
config MALI_PLATFORM_PBX
depends on ARCH_REALVIEW && REALVIEW_EB_A9MP && MACH_REALVIEW_PBX
bool "Realview PBX-A9"
config MALI_PLATFORM_THIRDPARTY
bool "Third Party Platform"
endchoice
config MALI_PLATFORM_THIRDPARTY_NAME
depends on MALI_MIDGARD && MALI_PLATFORM_THIRDPARTY && MALI_EXPERT
string "Third party platform name"
help
Enter the name of a third party platform that is supported. The third part configuration
file must be in midgard/config/tpip/mali_kbase_config_xxx.c where xxx is the name
specified here.
config MALI_DEBUG
bool "Debug build"
depends on MALI_MIDGARD && MALI_EXPERT
default n
help
Select this option for increased checking and reporting of errors.
config MALI_FENCE_DEBUG
bool "Debug sync fence usage"
depends on MALI_MIDGARD && MALI_EXPERT && SYNC
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_NO_MALI
bool "No Mali"
depends on MALI_MIDGARD && MALI_EXPERT
default n
help
This can be used to test the driver in a simulated environment
whereby the hardware is not physically present. If the hardware is physically
present it will not be used. This can be used to test the majority of the
driver without needing actual hardware or for software benchmarking.
All calls to the simulated hardware will complete immediately as if the hardware
completed the task.
config MALI_ERROR_INJECT
bool "Error injection"
depends on MALI_MIDGARD && MALI_EXPERT && MALI_NO_MALI
default n
help
Enables insertion of errors to test module failure and recovery mechanisms.
config MALI_TRACE_TIMELINE
bool "Timeline tracing"
depends on MALI_MIDGARD && MALI_EXPERT
default n
help
Enables timeline tracing through the kernel tracepoint system.
config MALI_SYSTEM_TRACE
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_GPU_MMU_AARCH64
bool "Use AArch64 page tables"
depends on MALI_MIDGARD && MALI_EXPERT
default n
help
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.
config MALI_PWRSOFT_765
bool "PWRSOFT-765 ticket"
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.
