• Code repos on xenbits - not done
• Development repositories are deployed on GitHub Xen Troops project
• Whitepapers - done, see Automotive Whitepapers

Features development

Initial contribution by GlobalLogic

• Automotive SoCs support
  • TI Jacinto 6 support - done
  • Renesas R-Car gen 2 support - done
  • Renesas R-Car gen 3 support - done
• QNX IPL and drivers - abandoned, as interest has shifted from QNX to AGL, for which there is an upstream. The risk of having to maintain an unnecessary Xen port was considered too high at this stage
• Initial cpufreq implementation in XEN
• Initial PV drivers APIs implementation (tty, RTC, audio, event, rpmsg)

Xen 4.9 release

• major PV drivers APIs: sound, display, input - done
  • frontend and backend implementations available on GitHub (see below)

Xen 4.10 release

• generic co-processor (GPU, DSP, FPGA, TPU, ...) virtualization support
  • vcoproc design documentation created
  • initial implementation in progress
• deprivileged applications in Xen on ARM
  • initial stubdom support for ARM done
  • initial EL0 deprivilege support done
  • will be use for non-upstreamable drivers (GPU, TEE, PMIC, etc.)
  • may be also used for PL011 emulation required by Linaro spec
• integration with ARM TrustZone based on OP-TEE
  • virtualization-friendly memory management in OP-TEE implementation - done
  • multiple domain support for TAs
  • SMC/HVC bridge in Xen
• hard real time scheduling integration
  • see RTDS-Based-Scheduler

Future

• yocto-based build management integrations
• dom0 RTOS support (FreeRTOS? Arctic Core – Open Source Autosar?)
• IEC 61508 safety certification - see similar OSADL Sil2LinuxMP project for Linux
• power management support
• heterogeneous computing support (big.LITTLE, etc.)
