This patch series adds the listed features that have been missing in upstream fastRPC driver. - Redesign and improve remote heap management. - Add static PD restart support for audio and sensors PD using PDR framework. - Add changes to support multimode invocation ioctl request. This ioctl call facilitates multiple types of requests from user including CRC check, performance counters, shared context bank usage, etc. This series also carries patch to save and restore interrupted context. - Add early wakeup support to allow DSP user to send early response to CPU and improve fastrpc performance. - Add polling mode support with which driver polls on memory to avoid CPU from going to low power modes. - Add notifications frameworks to provide users with the DSP PD status notifications. - Add a control mechanism to allow users to clean up DSP user PD - Add wakelock management support - Add DSP signalling support - Add check for untrusted applications and allow trusted processed to offload to system unsigned PD.
Could you precise: - Which workload are you fixing - Which platforms are concerned - Which platforms were tested So far I've been trying to run the "getserial" on SM8550-QRD and SM8650-QRD without success, would those changes fix this ? Is there any chance we could get an open-source minimal implementation of a fastRPC SDK using the open-source Hexagon LLVM like we have for the AIC100 ? It would definitely help validating the upstream fastRPC implementation. Thanks, Neil
