KVM on E500 core cpu MPC8572_E

[manikanta]

Hi,

MPC8572_E cpu is a dual core, we are using one core loaded with ios image and second core was brought up with Linux 2.6.32. we are looking for options to enable KVM on the dual core,

by editing /nobackup/usr1/sup2t/target/configs/p1021_c800_kernel_defconfig       
and adding vt and kvm config

CONFIG_VIRTUALIZATION=y
CONFIG_KVM=y
CONFIG_KVM_E500=y
CONFIG_TUN=y

and while building kernel image, following error message was displayed. "error: too many arguments to function 'trace_kvm_stlb_inval'"

please do the needful in helping to build kernel image with KVM support.

Error message:

bgl-ads-1348:240> make CWAN_PLATFORM=p1021_c800

1. Which Freescale Linux BSP you are using?

2. Why "P1021" is mentioned here, if the device is MPC8572 ?

Hi,

  MPC8572 is a dual core, in one core running ios image and we brought up second core with Linux image 2.6.32, this image was given by freescale team to boot up second core with Linux. P1021 is the image type used to turn on dual core, boot kernel and Linux OS.

p1021_c800-uboot-image.bin

rootfs_p1021_c800.ext2.gz.uboot

p1021_c800-linux-image.uImage

thanks

Now I am trying to bringup VT and KVM on it, is there any procedures to be followed to make it up. please share the info for the same.

Thanks

Even if you get it working, you'll miss out on a lot of bugfixes and significant performance improvements.  I strongly recommend using a much newer kernel.
