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
I have separated out the C71 platform driver pieces (patches 1 & 4) and posted a v2 for those.
Appreciate any feedback on the core patches (patches 2 & 3) that add the minimal 64-bit trace support, as this also sets the direction for resource extensions. I can post the next version for those based on feedback.
regards Suman
