No meeting on 12/31

by Bill Mills

Hello, There were only four of us on the call today so we called it off after 10 minutes. There is no meeting on Dec 31 so our next meeting will be Jan 14. (I did send a cancellation for the Dec 31 but it may still be on your calendar so please delete it manually.) I hope everyone enjoys whatever winter holidays you practice. See you in the new year. Thanks, Bill

[OpenAMP/libmetal] 73f746: lib/system/linux: pass correct offset to metal_map()

by Léo Sartre

Quoting the same documentation: "To map the memory of mapping N, you have to use N times the page size as your offset" So wee need to pass i * getpagesize() to get the correct mapping, otherwise, we end up with all io_region pointing to the same area.

Document this limitation until this offset is handled properly by the library.

Re: [Openamp-rp] embOS support for OpenAMP rpmsg

by Ed Mooring

Hi Til, This is the right place to ask. Your understanding of the process is correct. See https://github.com/OpenAMP/libmetal/pull/139 for adding support for a new processor/OS. To answer your other questions: 1. There is no further documentation for RTOS vendors implementing libmetal. 2. See the above pull request for how to get your changes into the repository. Documentation, and if possible, adding building libmetal and its tests for embOS to the GitHub continuous integration for libmetal would be very welcome.
