RPMsg in U-Boot Proof of concept Patch v1

by Shah, Tanmay

Hello All, RPMsg in U-Boot is under development. First proof of concept patch v1 was sent to upstream mailing list as RFC patch here: http://patchwork.ozlabs.org/project/uboot/list/?series=365 Here is the video of demo of RPMsg framework introduced in above patch series: https://www.youtube.com/watch?v=PxGNR_FYGt8 This document explains patch series and motivation to introduce RPMsg in U-Boot and future work that needs to be done: https://drive.google.com/file/d/1Bjtzj58klMPVuWEtRK89oyem7_Hdajn8/view?usp=… This patch series is very basic implementation of virtio based RPMsg framework referenced from the Linux kernel. For now, U-Boot is communicating with remote processor over fix hard-coded endpoint. More advance features such as name-service, multiple endpoint support etc.. will be added in coming revisions of this patch series. Meanwhile, please feel free to review existing work and provide review comments and any other suggestions. Thanks, Tanmay Hello All, RPMsg in U-Boot is under development.

[RFC PATCH 00/10] Add RPMsg framework

by Tanmay Shah

Remote Processor Messaging (RPMsg) framework is used to communicate with remote processor. RPMsg is a virtio-based messaging bus that allows U-Boot drivers to communicate with remote processors available on the system. This patch also introduces new virtio transport layer driver. To keep things minimal for now hard-coded endpoint is used in U-Boot to communicate with remote processor using RPMsg protocol. This will be modified to use multiple endpoints in future. U-Boot can't receive interrupts from remote processor as per design. Hence, user has to know when the data will be available from remote processor and call rpmsg_recv accordingly. Mostly it will be called to receive response of query done using rpmsg_send. Some code is already available to allocate memory for RPMsg however, that framework is mostly TI platform specific and isn't used by any other platforms. This series makes sure it does not break previous code for other platforms. If platforms wants to use this new framework it is expected to set "support_rpmsg_virtio" flag in relative remoteproc device's platform data. Also the framework introduced by this series is ported from the Linux kernel so other platforms which already support RPMsg in the Linux kernel can easily use this framework in U-Boot as well. --- Tanmay Shah (10): remoteproc: move resource table definition firmware: zynqmp: move zynqmp_pm_request_node API remoteproc: add remoteproc virtio transport driver drivers: add RPMsg framework rpmsg: add sample client driver cmd: add rpmsg framework commands remoteproc: add attach/detach commands remoteproc: add zynqmp driver configs: zynqmp: enable remoteproc and rpmsg configs: sandbox: enable rpmsg MAINTAINERS | 15 + arch/sandbox/dts/test.dts | 8 + cmd/Kconfig | 6 + cmd/Makefile | 1 + cmd/remoteproc.c | 14 +- cmd/rpmsg.c | 61 +++ configs/sandbox_defconfig | 4 + configs/xilinx_zynqmp_virt_defconfig | 6 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/firmware/firmware-zynqmp.c | 27 ++ drivers/power/domain/zynqmp-power-domain.c | 7 - drivers/remoteproc/Kconfig | 20 + drivers/remoteproc/Makefile | 2 + drivers/remoteproc/rproc-elf-loader.c | 33 -- drivers/remoteproc/rproc-uclass.c | 125 +++++- drivers/remoteproc/rproc_virtio.c | 422 +++++++++++++++++++++ drivers/remoteproc/xlnx_rproc.c | 411 ++++++++++++++++++++ drivers/rpmsg/Kconfig | 39 ++ drivers/rpmsg/Makefile | 13 + drivers/rpmsg/rpmsg-uclass.c | 156 ++++++++ drivers/rpmsg/rpmsg_internal.h | 52 +++ drivers/rpmsg/rpmsg_sample_client.c | 63 +++ drivers/rpmsg/sandbox_test_rpmsg.c | 88 +++++ drivers/rpmsg/virtio_rpmsg_bus.c | 384 +++++++++++++++++++ drivers/virtio/virtio-uclass.c | 1 + drivers/virtio/virtio_ring.c | 16 + include/dm/uclass-id.h | 1 + include/remoteproc.h | 130 ++++++- include/rpmsg.h | 145 +++++++ include/rproc_virtio.h | 33 ++ include/virtio.h | 7 +- include/virtio_ring.h | 32 ++ include/zynqmp_firmware.h | 30 +- test/dm/Makefile | 1 + test/dm/rpmsg.c | 41 ++ 36 files changed, 2321 insertions(+), 76 deletions(-) create mode 100644 cmd/rpmsg.c create mode 100644 drivers/remoteproc/rproc_virtio.c create mode 100644 drivers/remoteproc/xlnx_rproc.c create mode 100644 drivers/rpmsg/Kconfig create mode 100644 drivers/rpmsg/Makefile create mode 100644 drivers/rpmsg/rpmsg-uclass.c create mode 100644 drivers/rpmsg/rpmsg_internal.h create mode 100644 drivers/rpmsg/rpmsg_sample_client.c create mode 100644 drivers/rpmsg/sandbox_test_rpmsg.c create mode 100644 drivers/rpmsg/virtio_rpmsg_bus.c create mode 100644 include/rpmsg.h create mode 100644 include/rproc_virtio.h create mode 100644 test/dm/rpmsg.c base-commit: 94e7cb181ad6bd25d36a11c58e0df64e9f815888 -- 2.25.1
