This is the initial proposal for a paravirtualized IOMMU device using virtio transport. It contains a description of the device, a Linux driver, and a toy implementation in kvmtool. With this prototype, you can translate DMA to guest memory from emulated (virtio), or passed-through (VFIO) devices. In its simplest form, implemented here, the device handles map/unmap requests from the guest. Future

Hello, I'm new in R. I'm meteorological modeller and i will calculate some statistics for my model results. These statistis are the follow: ANB: Average Normalized Absolute BIAS MNB: Mean Normalized BIAS MNE: Mean Normalised Error STDE: Standard Deviation of Error FB: Fractional BIAS MG: Geometric Mean BIAS VG: Geometric Variance SKVAR: Skill Variance RMSE: Root Mean Square Error NMSE:

Hello? Does someone know how I manually renew Identity Management (FreeIPA) certificates on CentOS6 after they have expired? There is a solution on redhat.com (https://access.redhat.com/solutions/643753), but I can't see it. Please help, thank you! Li Yi

Hi all, I succeed in injecting audio into one channel by mean of ChanSpy, but this audio cannot be listened correctly. I am using softphones for Android and iPhone and there are so many cuts so that they cannot understand what is said in the audio file. Is this because the total RTP bandwidth is too much?. Which codec and format should I use for the files played with Playback application?

Dear all, Anyone of you knows how to play an audio file at the beginning of a call for both Caller and Callee? A(x) of Dial application only plays audio for callee. I don't want to use MeetMe because I want to use Monitor and MixMonitor. Thank you! ________________________________ Este mensaje se dirige exclusivamente a su destinatario.
