~~iceoryx_hoofs Coding rules: CamelCase or snake_case~~ Moved to the next meetup

Jakob works for NXP developing VehicleOS for Automotive
Hardware is called BlueBox 3
Project is called "Middleware acceleration on NXP platforms" and at prototype stage
Question from Christian:
- What operating systems do you use?
  - Linux, no production system yet
- How did you discover iceoryx?
  - Google and/or Eclipse Cyclone DDS
Blue Box has HPC CPU (LX2160A) and 2nd CPU (SG32G2274)
- They are connected over Ethernet and PCIe, want to use PCIe for fast communication
- Question from Simon:
  - Have you started the PCIe work?
    - Yes, it's working with DMA
Slide on S32G
- Arm Cortex M7 (embedded, 32-bit) and A53 (Linux core)
- What compiler are you using?
  - GCC everywhere
iceoryx gateway
- Developed a PCIe transport and "physical shared memory" (SRAM, at prototype stage)
- DMA supported
- No serialization
- They work on a fork of iceoryx, due to mem pool allocation with physically contiguous buffers
  - Very hacky, not contribution worthy
- Dynamic discovery mechanism using the introspection services
- Didn't use iox::gw::GatewayGeneric, don't use it anymore
- A port for FreeRTOS would be very interesting for NXP ("one code base for all platforms")
iceoryx experience
- Good experience :)
- iox::gw::GatewayGeneric not super useful
- Port queue full behaviour, notification when a sample is dropped would be nice, a middle way would be useful

Create two new issues to discuss the details and roadmap
- Physically contiguous buffers @Christian
- FreeRTOS port @Christian
  - Exchangeable IPC channel
