Hi All, This series adds support for a new next generation 64-bit TI DSP based on the TMS320C71x CorePac processor subsystem called the C71x. The support is enabled through couple of enhancements to the remoteproc core (primarily to support a 64-bit trace resource entry), and does depend on the K3 DSP remoteproc driver posted earlier today [1]. The loading support leveraged the 64-bit ELF loader support code added by Clement and already staged on the rproc-next branch. I am posting this series separate from the C66x series because of the new 64-bit resource type enhancement needs (patches 2 and 3). I have leveraged the existing resource types as is by introducing a new version element, and am open to ideas if it is desired to just define it as a separate resource type. The C71x DSP boots using firmware segments loaded into the DDR with a 2 MB aligned address requirement on the boot vectors. There is no support for internal memory loading, and all internal memories shall be used as fast RAMs/scatchpads by the firmware executing on the DSPs. IPC is through the virtio-rpmsg transport. There is no support for Error Recovery, Power Management or loading into on-chip SRAMs at present. Following is the patch summary: - Patch 1 updates the K3 DSP bindings for C71x cores - Patch 2 introduces a concept of version element into existing resource types - Patch 3 adds support for a new 64-bit trace resource entry - Patch 4 enhances the K3 DSP remoteproc driver for C71x regards Suman [1] https://patchwork.kernel.org/cover/11458573/ Suman Anna (4): dt-bindings: remoteproc: k3-dsp: Update bindings for C71x DSPs remoteproc: introduce version element into resource type field remoteproc: add support for a new 64-bit trace version remoteproc/k3-dsp: Add support for C71x DSPs .../bindings/remoteproc/ti,k3-dsp-rproc.yaml | 78 ++++++++++++++++--- drivers/remoteproc/remoteproc_core.c | 65 +++++++++++----- drivers/remoteproc/remoteproc_debugfs.c | 50 ++++++++---- drivers/remoteproc/ti_k3_dsp_remoteproc.c | 17 ++++ include/linux/remoteproc.h | 34 +++++++- 5 files changed, 203 insertions(+), 41 deletions(-) -- 2.23.0
