Embedded and Automotive/Archived/PV Drivers/Roadmap

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

Xen 4.10 release

• "Non-shared" IOMMU support - done
  • VMSA-compatible IOMMU in Renesas R-Car gen3 driver - done
• generic co-processor (GPU, DSP, FPGA, TPU, ...) virtualization support
  • vcoproc design documentation created
  • initial implementation in progress
  • drivers to be implemented as deprivileged applications
• integration with ARM TrustZone based on OP-TEE
  • SMC/HVC bridge in Xen
  • OP-TEE driver as a deprivileged app
  • changes in OP-TEE itself: dynamic memory management, multiple domains support
• 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, etc.)
  • may be also used for PL011 emulation required by Linaro spec

Future

• power management implementation
• hard real time scheduling integration, RTDS-Based-Scheduler
• yocto-based build management integrations (see meta-virtualization layer on Yocto Project git) (also see Xen_on_ARM_and_Yocto)
• heterogeneous computing support (big.LITTLE, etc.)
• dom0 RTOS support (FreeRTOS? Arctic Core – Open Source Autosar?)
• IEC 61508 safety certification - see similar OSADL Sil2LinuxMP project for Linux
