Re: [XenARM] Regarding ARMv7a architecture boards :: Xen-Unstable

Thanks for the information wrt. Fast Model.
It would be better if you can upload some screenshot so that I can
have the same configuration with others.
BTW, can I do some experiments with other peripherals such as netdev or blkdev?
In addition, can we profile and measure the basic performance such as
context switching or TLB flush overhead?
Is there performance counter for emulator that is similar to other ARM
processors?
