Hi Johnny,
May I ask a question: Which Linux package are you using?
Regards,
Duy
We use whitebox 5.x.
Hello Johnny,
I confirmed this is issue of Xen Hypervisor BSP.I tested latest Xen Hypervisor BSP and got kernel panic.Whitebox SDK is based on Xen hypervisor BSP so that it needs to fix Xen Hypervisor BSP at first.
FYI:Yocto BSP supports thermal driver.elinux.org/.../SDK-v3.16.2
Hi Y.H,
You mean Renesas will fix Xen Hypervisor BSP right? In next version?
And Yocto BSP thermal driver will get thermal successfully?
Hello,
I uploaded new patch for supporting thermal driver into v5.x-dev branch.This patch will be merged into next version of Whitebox SDK.I think this may help you.https://github.com/renesas-rcar/whitebox-sdk/commit/d2e0bae0e562780e77f51bfcdbb9c8e9a4efa41b
I confirmed both Spider and S4SK board.And, following is example output of S4SK:
root@s4sk-domd:~# cat /sys/class/thermal/*/temp410004050041000
I have already reported this issue to the Xen Hypervisor BSP team.But, currently detaild schedule is not existed so that I can not promiss it will be fixed in next version.
And Yocto BSP thermal driver will get thermal successfully
At least, S4SK was tested before releasing Yocto BSP on eLinux wiki.So, I think it works correctly. ( But, I have not yet tested it.)If you want to know more detail about thermal driver or SoC specification, please contact to Renesas official support using ticket system or via sales person.We can not talk about it here because documentaion is not published in public.
The patch is work.
Thanks!
