Embedded and Automotive/Archived/PV Drivers/Roadmap
From Xen
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
