The newest driver proposed for the Linux kernel’s accelerator “accel” subsystem is named QDA and is a Qualcomm DSP Accelerator driver.<\/p>\n

A request for comments (RFC) patch series was posted today for this Qualcomm DSP Accelerator driver for Hexagon DPs and provides a standardized interface for offloading computational tasks to DSPs found on Qualcomm SoCs and covering all DSP domains of ADSP, CDSP, SDSP, and GDSP.
\n<\/p>\n

\"FastRPC<\/p>\n

This Qualcomm QDA driver aims to be an alternative to Qualcomm’s FastRPC driver living within the kernel’s drivers\/misc\/ area. This new accelerator driver jives with the accel subsystem, provides better resource management, and other features similar to other accelerator drivers.
\n
* Standard DRM accelerator interface via \/dev\/accel\/accelN
\n
* GEM-based buffer management with DMA-BUF import\/export support
\n
* IOMMU-based memory isolation using per-process context banks
\n
* FastRPC protocol implementation for DSP communication
\n
* RPMsg transport layer for reliable message passing
\n
* Support for all DSP domains (ADSP, CDSP, SDSP, GDSP)
\n
* Comprehensive IOCTL interface for DSP operations
\n
The QDA driver in current form with today’s patch series comes in at 4,665 lines of C code.<\/p>\n

There is an open-source user-space driver to interface with QDA via Qualcomm’s FastRPC accel\/staging GitHub branch.<\/p>\n
