Dear Jailhouse develop Team, We are Marelli(Guangzhou) Team, We are now developing TI J7 board, as we know, TI use the jailhouse hypervisor with their Cockpit Demo. Now Marelli team want to know more detail about the jailhouse hypervisor, we have some questions, Could you pls help to confirm? Thanks.
Question: 1. Can the hypervisor allocation HW resource dynamically when hypervisor running? such as below resource, could be dynamically changed? a. CPU core (Adaptive cpu resource share) b. DDR size (Adaptive memory resource share) c. GPU core (Virtual GPU module share) d. GPIO/I2C/SPI/I2S etc. 2. if the hypervisor could not allocation HW resource dynamically, how the design logic of hypervisor allocate resource? pls share some introduce documents if have. 3. Does the hypervisor have some KPI data? such as below info a. How Fast boot time when OS mount filesystem; b. How Fast boot time to show first image? c. How Fast boot time to play audio? d. How Fast boot time to show RVC? e. How Fast boot time to run second OS filesystem and touch? 4. What’s the communication solutions between different OS? Does it support sharemem, socket, or another fast/ large-capacity data communicate method? 5. Does the hypervisor Support posix interface or not? have some method that easy for porting Application from our former OS? if do not support posix, have another method to port easy? 6. Pls list the hypervisor Support how much connectivity features; such as BT/ BT LTE, Wi-Fi, ethernet stack pass TC8 test, USB Ethernet(NCM, RNDIS), ZigBee etc. 7. pls list how many Host OS does hypervisor support So far? (such as Linux, Linux AGL, QNX for Cluster etc) 8. Pls list how many Guest OS does hypervisor support So far? (such as Linux, Android, Linux AGL, QNX for IVI etc) 9. Does the hypervisor had Supported 3rd party SW lib(such as DOIP, SOMEIP, Adaptive Autosar, OTA solution) ? 10. what kind of program language(such as C, C++, Python, Java, etc.) can support? 11. Is the hypervisor open source ? 12. What kind of development tool chain(such as Compile, Debug and analyze tools) can support to develop bsp and application? such as use the IDE could debug step by step? such as use which Compile to compile application? GCC or itself compile? have tool to analyze hypervisor system performance(CPU load, GPU load, DDR bandwidth)? 13. What is the fault handing mechanism on the hypervisor(such as Ramdump, VM crash, coredump)? How does the hypervisor analyze the system crash? 14. What the hypervisor have got Safety certification level? if no safety certification, pls share some introduce how does it make safety? 15. what is the hypervisor Maturity? such as In J7 platform, how many bsp driver have release? how many project on going and SOP? 16. What’s the security support of this hypervisor? Does it support security boot, sandbox, MAC, security filesystem, SCM, DMM, firewall, Security unpack, SRTC, TLS etc? if the hypervisor have security feature list, pls share. 17. How many resource usage when the hypervisor running? (such as Resource usage: CPU, RAM, ROM) 18. Does the hypervisor had team support in China? or which side support when Chinese GuangZhou have the hypervisor project? 19. What kinds of HMI engine can this hypervisor support(such as QT, Kanzi, Altia, CGI Studio, crank, html5 etc)? 20. Does the hypervisor have some technical document(user guide) are public? if have website or link. if no, how could we get these technical document? 21. Does the hypervisor had use in OEMs? pls share some info. 22. How do we get the hypervisor license? Is it free(no NRE, royalty) to get license? 23. Is is free(no NRE, royalty) to use the hypervisor and its hypervisor modules, Customize Support Package, Tool Chain, Special function lib?
