KVM Support?

Thu Aug 30 11:19:14 AEST 2018

Hi Avi ,Joseph,
   I checked the patches for bmc side, the rest_dbus.py on bmc was not patched sucessfully. 
The files on bmc are: 
/run/initramfs/ro/usr/lib/python2.7 /site-packages/obmc/wsgi/apps/rest_dbus.py
/usr/lib/python2.7/site-packages/obmc/wsgi/apps/rest_dbus.py

I patched the file on phosphor-gevent .
Now I patched  the   rest_dbus.py on phosphor-rest again,the file of bmc side has updated.

Now it works.

Thanks,
Xiuzhi

Hi Xiuzhi,

Can you take the patches and merge them to your environment?

Josef,

Maybe you need to give the commit or tag you are that above it you use your patches? 

Thanks,

Avi

Hi Xiuzhi:

I think we are using different bases of the openbmc, this patch is really working on my side

Sorry for I cannot find the exact error in your message.

Hi Joseph, Ed,
    There was an error when I  updated the patches  https://github.com/Nuvoton-Israel/meta-openbmc-nuvoton-addon/commit/140771b7e898dd5ca8f0364290cce669609088ac
 Would you like to give me some suggestions to debug it?
 When I logged in https://<bmc_ip>/#/kvm, The errors read:

>Hi Eddie & Ed:   >Do you have any plan to support non-jpeg video stream in obmc-iKVM? >It is possible some platforms don't have hardware JPEG engine, instead have the RGB video stream. >If possible to support RGB video stream, I think it would be better if you can add the video frame differentiation in obmc-iKVM because we don't need to send the full screen >to VNC client on every request, it can reduce the buffer size at least. (libvncserver already has the video frame differentiation)   >Also, I have implemented a KVM application for our platform(nuvoton evb-npcm750) which has hardware video frame differentiation and hardware hextile engine. https://github.com/Nuvoton-Israel/obmc-ikvm https://github.com/Nuvoton-Israel/linux/commit/7e90f572323e56e9425b85aafe86dfa5a35c4e7d   >I also enabled ED's KVM webui and added kvmws proxy in python web server. https://github.com/Nuvoton-Israel/meta-openbmc-nuvoton-addon/commit/140771b7e898dd5ca8f0364290cce669609088ac   >If you can spare a few minutes to review my implementation is my pleasure.   >Currently, my video driver is not v4l2, so I am going to redesign it to fit v4l2 and your obmc-iKVM, then I will try to add the RGB format support in your obmc-ikvm.   >Regarding the larger binary size, I think we need to review all configurations of libvncserver and check which functions should be disabled.   >Thanks, >Joseph Liu.
