ACRN Project TCM - 22th May 2019
  1. ACRN project update
  • 2nd ACRN Meetup schedule on 6/11-12 in Shanghai, as part of IoT open source community seminar. You’re welcome to register and join!
  1. CAO, Minggui: Logger Improvement on acrn-dm
Download foil from ACRN Presentation->ACRN_TCM->WW21’19
Q1: How to sync ACRN timestamp sync with kernel time? Follow kernel rule?
A1: yes, we’ll follow kernel rule for the timestamp. So it is easy to sync with kernel log.
Q2: There’ll be multiple acrn-dm threads when running multi VMs, how to distinguish the acrn-dm log message?
A2:  We will add vm index into logger kmsg and disk-file to distinguish the different VM/acrn-dm instances.
Q3: Do we have a filter to filter specific VMs?
A3: Do the filter offline rather online to avoid missing information. We can use the tool name TextAnalysisTool.NET to parse the log message and add some filter to select which message that we want to check. It is very powerful tool for log analysis. We can use text t
Q4: Will be crash dump file saved?
A4: Only core file be saved.
Q5: Any guiding rules for developers to follow in order to fulfill the logger system?
A5: we’ll add some ones in our github website for that.
  1. All: Community open discussion.
