Re: [vfio-users] passthrough VGA for widespread use?

What about input lag with the patch? The point of using passthrough on usb controller is to get direct input for games On Mon, 29 Feb 2016 at 21:37, Jonathan Scruggs wrote: > Those patches are supposed to be added to mainline at some point. They are > stable and work great! > On 29 Feb 2016 20:33

Those patches are supposed to be added to mainline at some point. They are stable and work great! On 29 Feb 2016 20:33, "Will Marler" wrote: > Oh, good point, that is an option too (although I personally I stay away > from patching) > > On Mon, Feb 29, 2016 at 1:29 PM, Jonathan Scruggs > wrote:

Re: [vfio-users] passthrough VGA for widespread use?

For keyboard and mouse, grab the patches in this mailing list that pass through your host keyboard and mouse as a standard PS/2 device. You press both CTRL keys to switch between host and guest. Works very well. You also have full BIOS control of the guest and Windows UAC pop-ups can be clicked on

Re: [vfio-users] passthrough VGA for widespread use?

a) I've never had Host or Guest crash problems. I have had problems with programs crashing in the guest with nebulous errors (or no errors) that seem related to graphics. They are reproducible, but not reliably so, and I have never tried to verify if those crashes exist on baremetal. d) Synergy wo

I notice a lot of interesting comments buried in various threads on this mailing list, forum posts and blogs Is there any possibility of gathering relevant material into wiki pages? For example, just getting all the tips about choice of kernel and compile options into a single page would make i

I made the process threw scripts just because cset doesn't work on debian :) rcu_nocbs should moving much of kernel threads out of the selected cpus. A good example to know that your vcpus are not used is, for intel, to use turbostat. It show the activity of threads, and the average / top frequen

I tried nohz_full/rcu_nocbs in the past but it did not show any visible improvement. I will try again i guess. I however had similar setup with cset, although done rather manually. > cset set -c 0-1 system > cset proc -m -f root -t system -k This essentially moves all tasks to cores 0 and 1. Since

Re: [vfio-users] Brutal DPC Latency - how is yours? check it please and report back

Near as efficient as isolcpus, but can be used dynamically, during run: Use nohz_full / rcu_nocbs, to offload all rcu of your vm core to your OS-only cores Use cgroups, when you start vm, you keep only x core to the OS, when you shut it down, let the OS have all cores. If vm is started and you ne

Re: [vfio-users] Brutal DPC Latency - how is yours? check it please and report back

Two things you can improve, IMO * disable NO_HZ * use isolcpus to dedicate your pinned CPUs to guest only - this will also ensure they are not used for guest IO. B. On 29/02/2016 08:45, Rokas Kupstys wrote: Yesterday i figured out my latency problem. All things listed everywhere on interne

Yes currently i am actually booted with vanilla archlinux kernel, no NO_HZ and other stuff. > Why does 2 core for the host is unacceptable? You plan to use it > making hard workloads while gaming? Problem with isolcpus is that it exempts cores from linux cpu scheduler. This means even if VM is offl

Re: [vfio-users] Brutal DPC Latency - how is yours? check it please and report back

Yesterday i figured out my latency problem. All things listed everywhere on internet failed. Last thing i tried was pinning one vcpu to two physical cores and it brought latency down. Now i have FX-8350 CPU which has shared FPU for each two cores so maybe thats why. With just this pinning latency n
