[OpenAMP/libmetal] 30af01: FreeRTOS: fix sleep and timestamp handling

by Arnaud Pouliquen

Branch: refs/heads/master Home: https://github.com/OpenAMP/libmetal Commit: 30af011301c5778075266e4b5189e61a35093265 https://github.com/OpenAMP/libmetal/commit/30af011301c5778075266e4b5189e61a… Author: Ed Mooring <ed.mooring(a)xilinx.com> Date: 2020-10-15 (Thu, 15 Oct 2020) Changed paths: M lib/system/freertos/sleep.h M lib/system/freertos/time.c M test/system/freertos/sleep.c Log Message: ----------- FreeRTOS: fix sleep and timestamp handling libmetal's libmetal_sleep_usec() takes a sleep time in micro-seconds. The FreeRTOS function underlying it takes a sleep time in task ticks. This was not properly corrected for, resulting in sleep times that were off by an order of magnitude. The test code attempted to correct for this as well, in the same wrong way. Lastly, the metal_get_timestamp() function returned a value in task ticks alone. This is a configuration dependent value. This patch changes all three places to use microseconds for the input and output values. Signed-off-by: Ed Mooring <ed.mooring(a)linaro.org>

Re: [Openamp-rp] Activity on core 0 affects performance on core 1

by Stefano Stabellini

Hi Gaute, When you say that you are running Linux on core 0 and FreeRTOS on core 1, do you mean that you are running both Linux and FreeRTOS on the Cortex-A cluster in separate virtual machines, using a hypervisor? Or are they running on separate clusters, such as FreeRTOS on Cortex-M/R and Linux on a Cortex-A?

Activity on core 0 affects performance on core 1

by Gaute Nilsson

We are running Linux on core 0 and FreeRTOS on core 1. We have a high priority FreeRTOS task that needs to run with a 100 µs interval. When the system is up and running, no cross core communication takes place. If I login with a ssh session into the Linux core, this will cause a performance hit on the FreeRTOS core and cause the high priority task to miss its deadline. I can see that even an ISR on FreeRTOS core that normally takes 4.5 µs to execute, temporarily will take 7.6 µs to execute just when I open a ssh session into Linux core. So everything will temporarily run slower on FreeRTOS core before it goes back to normal. What can cause this, and how can we prevent activity on Linux core affecting performance on FreeRTOS core? -Gaute Nilsson We are running Linux on core 0 and FreeRTOS on core 1.
