Emulating Raspberry Pi 4 with Qemu

Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.

Hope it helps! :D

Flipper Zero developer Q&A

August 6th 2022

Below are my notes regarding every question asked and answered, covering both sessions.
While the 1st session's audio is lost to time, I have a full recording of the second session.
Stream and download the MP3 here: https://nc.dj.je/s/9FZAqbs9LwcSnio (I'm looking for a better way to host the file, perhaps I might upload the next one to archive.org)

NOTE: The transcription of questions and answeres may contain errors, take it all with a grain of salt.

/**
   POC of cache composing. 
   
   The idea behind this madnes was to compose multiple layers of LRU type caches,
   with the first layer being local (LRUMemcache) with a 1:1 with configured TTL, and for each subsequent tier 1:n of the configured ttl.
 
   In effect that would mean that when a cached item gets shifted out of the first layer due to being regarded as the least recently used,
   it would still exising in the second layer giving it a grace period of sorts before deleting the cache entry from all layers.
 
   BUT WHY you may ask?

Docker Macvlan and Ipvlan Experimental Driver Examples

• The build will be vendored into github.com/docker/docker in the next few days. In the meantime here is the binary that will be getting vendored. docker-1.11.0-dev.zip
• Ipvlan L2 mode network with multiple subnets without a parent specified
• For a long test that will create 54 networks and 120+ containers, then delete them all and recreate them again try ipvlan-macvlan-it.sh Instructions here Docker Macvlan and Ipvlan Manual IT Test
• FYI Note: When the parent is empty or the --internal flag is used, a linux type dummy interface is dynamically created by Libnetwork to act as the parent. This network is completely isolated and is the equivalent to a --internal flag. This is a good mode for demoing.
• The first test requires an interface
