config MSM_ADSPRPC
tristate "QTI FastRPC driver"
depends on QCOM_GLINK
help
Provides a communication mechanism that allows clients to
make remote method invocations across processor boundary to
applications/compute DSP processor.
Say M if you want to enable this module.
config ADSPRPC_DEBUG
bool "Debug logs in FastRPC driver"
help
Enable debug logs in the fastrpc driver. Flag will be
disabled by default to maximize RPC performance as debug
logging will impact RPC overhead.
Say Y here if you want to enable the logs.
config ADI
tristate "SPARC Privileged ADI driver"
depends on SPARC64
