Hi Eddie,
   My bmc is AST2400, I modified the aspeed-g4.dtsi(adding  gfx: display@1e6e6000  and  video: video@1e700000)
 and the aspeed-bmc-opp-xxx.dts (adding &video &vhub) . 
An error occured when I executed the following instructions:

root@zhaoxinc:~# create_usbhid.sh 
root@zhaoxinc:~# obmc-ikvm -v /dev/video0 -i /dev/hidg0
[  125.586061] aspeed-video 1e700000.video: timed out on 1st mode detect
[  125.602732] aspeed-video 1e700000.video: Failed to start video engine
failed to open /dev/video0: 62 Timer expired
Need I modify drivers/media/platform/aspeed-video.c or any other files?
 
 Thanks ,
Xiuzhi

Hi,

You need to make sure the video device is enabled in your device-tree 
for the machine you use... My kernel patch enabled it for our AST2500 
witherspoon system. If you're using AST2500 as well, then you just need 
something like:

&video {
     status = "okay";
     memory-region = <&gfx_memory>;
};

And the virtual USB hub:
&vhub {
     status = "okay";
};

If you're not using AST2500, you'll need more changes to device-tree.

Then on the BMC command line:
create_usbhid.sh
obmc-ikvm -v /dev/video0 -i /dev/hidg0
And connect with any VNC client to port 0 of your BMC IP.

Thanks,
Eddie
