Meeting today at 4 PM London, 11AM New York

by Bill Mills

All, We have our normal meeting today. Last week in the special meeting we decided to talk about buffer size negotiation this week. See this link for a rpmsg.pdf https://github.com/OpenAMP/open-amp/issues/271 I know I am delinquent of the "summary of proposal" for the "Support the two phase creation handshake" last week. I looked at this all last weekend. I think the right thing to do is a bit more complicated than what we were discussing last week. I suggest that today we focus on the buffer size negotiation and put off the discussion of the two phase creation handshake. Thanks, Bill Topic: OpenAMP RP Call Time: Every two weeks on Thursdays starting Feb 25, 2021 04:00 PM London Join Zoom Meeting https://linaro-org.zoom.us/j/95276449391?pwd=eDRCQzlnZGN1VlUvaFNoZ0V3RlNEZz… Meeting ID: 952 7644 9391 Passcode: 8250 -- Bill Mills Principal Technical Consultant, Linaro +1-240-643-0836 TZ: US Eastern Work Schedule: Tues/Wed/Thur

Special Meeting this Friday

by Bill Mills

All, I just sent out an invitation for this Friday at 10am US Eastern time (New York etc). I think that should still be 3pm UK/UTC time. Google cal link: https://calendar.google.com/event?action=TEMPLATE&tmeid=M2R0a2licjhhNDdybXU… This is a special meeting to discuss https://github.com/OpenAMP/open-amp/pull/246 https://github.com/OpenAMP/open-amp/pull/238 https://github.com/OpenAMP/open-amp/pull/160 https://github.com/OpenAMP/open-amp/pull/155 The above are all pull requests from Xiang Xiao and most involve changes to the protocol between two processors. We need to make sure we do such changes carefully and: * maintain back compatibility when the other processor is running older code, fallback gracefully * implementation is possible for both Linux kernel and baremetal/RTOS * is general purpose and will server a wide range of use cases In general I think everyone wants to see changes like this we just need to find the right form. Anyone in this list may join but the meeting is focused on the people in the to: list. Thanks, Bill -- Bill Mills Principal Technical Consultant, Linaro +1-240-643-0836 TZ: US Eastern Work Schedule: Tues/Wed/Thur

No meeting for Feb 25

by Bill Mills

All, I have canceled tomorrows call due to conflicts. Matthieu and Ed have said there is not a ton to talk about anyway. Heads up that we are trying to schedule a special call next week at an earlier time than usual (better for China) so we can discuss the idea of EP connect / disconnect notification. I will update the list when we nail down a time. Thanks, Bill -- Bill Mills Principal Technical Consultant, Linaro +1-240-643-0836 TZ: US Eastern Work Schedule: Tues/Wed/Thur

New with OpenAMP

by Sara Alonso

Hi! I am a PhD student and I am using OpenAMP for a research work. I am trying to compare latencies between a FreeRTOS application in R5 with OpenAMP and a FreeRTOS application in A53 with Xen hypervisor. I am using a zynq ZCU102 platform. I have just started the PhD, so I am not completely sure of what I am going to do for the thesis. I wanted to relate this (OpenAMP, hypervisors...) with the FPGA, but I don't know how. Now my intention is to do a paper (my first article) about the latencies with OpenAMP and Xen. If someone has any advice for me, I'd be glad to listen to it. Also, when I get stuck at something (I am new using OpenAMP) I wolud like to ask you for support if you agree. Thank you very much! Sara Hi!

[OpenAMP/libmetal] f252f0: FreeRTOS: Allow tick rates greater than 1000 for m...

by Ed Mooring

Branch: refs/heads/master Home: https://github.com/OpenAMP/libmetal Commit: f252f0e007fbfb8b3a52b1d5901250ddac96baad https://github.com/OpenAMP/libmetal/commit/f252f0e007fbfb8b3a52b1d5901250dd… Author: Ed Mooring <ed.mooring(a)linaro.org> Date: 2021-01-11 (Mon, 11 Jan 2021) Changed paths: M lib/system/freertos/sleep.h Log Message: ----------- FreeRTOS: Allow tick rates greater than 1000 for metal_sleep_usec(). metal_sleep_usec() used portTICK_PERIOD_MS to determine how long to sleep. If the FreeRTOS tick rate is set to greater than 1000, this will be 0, resulting in a divide by zero error at run time. This changes it to use pdMS_TO_TICKS(), which can accomodate higher tick rates.
