| bool "Helper functions for securing buffers through TZ" |
| help |
| Say 'Y' here for targets that need to call into TZ to secure |
| memory buffers. This ensures that only the correct clients can |
| use this memory and no unauthorized access is made to the |
| buffer |

| config ICNSS |
| tristate "Platform driver for Q6 integrated connectivity" |
| ---help--- |
| This module adds support for Q6 integrated WLAN connectivity |
| subsystem. This module is responsible for communicating WLAN on/off |
| control messages to FW over QMI channel. It is also responsible for |
| handling WLAN PD restart notifications. |

| config MSM_CORE_CTL_HELPER |
| tristate "Core control helper functions for dynamically hotplug CPUs" |
| help |
| Provide helper functions for core control driver. Core control |
| driver dynamically hotplugs CPUs from kernel based on current |
| system load and state. It also supports limiting min and |
| max online CPUs from userspace. |

| config MSM_BAM_DMUX |
| bool "BAM Data Mux Driver" |
| depends on SPS |
| help |
| Support Muxed Data Channels over BAM interface. |
| BAM has a limited number of pipes. This driver |
| provides a means to support more logical channels |
| via muxing than BAM could without muxing. |

| config MSM_PERFORMANCE |
| tristate "Core control driver to support userspace hotplug requests" |
| help |
| This driver is used to provide CPU hotplug support to userspace. |
| It ensures that no more than a user specified number of CPUs stay |
| online at any given point in time. |

| config MSM_PERFORMANCE_HOTPLUG_ON |
| bool "Hotplug functionality through msm_performance turned on" |
| depends on MSM_PERFORMANCE |
| default y |
| help |
| If some other core-control driver is present turn off the core-control |
| capability of msm_performance driver. Setting this flag to false will |
| compile out the nodes needed for core-control functionality through |
| msm_performance. |

| config MSM_POWER |
| tristate "Power driver to manage system resources" |
| help |
| This driver monitors and manages system resources for better |
| power efficiency. It keeps track of the current frequency of |
| several resources (e.g. CPU and GPU) to manage other system |
| resources (e.g. DDR frequency) more efficiently. |

| config MSM_SERVICE_LOCATOR |
| bool "Service Locator" |
| depends on MSM_QMI_INTERFACE |
| help |
| The Service Locator provides a library to retrieve location |
| information given a service identifier. Location here translates |
| to what process domain exports the service, and which subsystem |
| that process domain will execute in. |
| |
| config MSM_SERVICE_NOTIFIER |
| bool "Service Notifier" |
| depends on MSM_SERVICE_LOCATOR && MSM_SUBSYSTEM_RESTART |
| help |
| The Service Notifier provides a library for a kernel client to |
| register for state change notifications regarding a remote service. |
| A remote service here refers to a process providing certain services |
| like audio, the identifier for which is provided by the service |
| locator. |

| bool "Protect kernel text by removing write permissions in stage-2" |
| depends on !FUNCTION_TRACER |
| help |
| On hypervisor-enabled targets, this option will make a call into |
| the hypervisor to request that the kernel text be remapped |
| without write permissions. This protects against malicious |
| devices rewriting kernel code. |
| |
| Note that this will BREAK any runtime patching of the kernel text |
| (i.e. anything that uses apply_alternatives, |
| aarch64_insn_patch_text_nosync, etc. including the various CPU |
| errata workarounds in arch/arm64/kernel/cpu_errata.c). |
