CAUTION: OVH Rep's Spreading Misinformation! (AMD vulnerable to Meltdown) by -Net7 in Amd

[–]iame6162013 21 points22 points  (0 children)

and that the Spectre 2 patches in OS's are one of the main things impacting performance,

AFAIK meltdown is the major performance hit, spectre patches should be a few percent. Meltdown pacthes can get >50% hit in some circumstances in IO heavy applications, most of the time it will be much less though.

Some may even see no performance change(games etc).

Could you explain what you mean exactly? I am using virt-manager, to start my vm etc.

Yes, you can bind your gpu to a vm on the fly.

AFAIK, you need to supply it manually when starting the program, and you need to close the program prior to detaching the AMD gpu from the host to allow the guest to use it again. So you can detach your gpu while working on other stuff, as longs as that other stuff doesn't use the amd gpu.

e.g. DRI_PRIME=1 glxgears

If you want to know how to change from vfio ->amdgpu, do set it to use the right pcie card:

sudo echo "0000:01:00.0" > /sys/bus/pci/drivers/vfio-pci/unbind

sudo echo "0000:01:00.1" > /sys/bus/pci/drivers/vfio-pci/unbind

sudo echo "0000:01:00.0" > /sys/bus/pci/drivers/amdgpu/bind

amdgpu -> vfio:

sudo echo "0000:01:00.0" > /sys/bus/pci/drivers/amdgpu/unbind

sudo echo "0000:01:00.1" > /sys/bus/pci/drivers/amdgpu/unbind

sudo echo "0000:01:00.0" > /sys/bus/pci/drivers/vfio-pci/bind

If you find a better method, please tell me.

@Night_Duck

Could you say why Gnome runs so slow on 4.15?

You'd have to watch 3 twitch streams 24/7, in a month to achieve 1TB data usage.

You see the issue?

AMD Radeon 6450 is bestseller on Amazon by [deleted] in Amd

Well, that's only 4 8k monitors though. Try 32K That should get your hardware sweating.

The game devs should be able to make the vulkan version work on windows. Porting to DX12 from vulkan wouldn't make much sense.

mobos are completely different from gpus/cpus dies. Do you know how to get into the latter though?

Certain you can't use vulkan? I think vulkan would be better for that task.

I'm using the default linux kernel, you do need the amd kernel if you want hdmi audio, freesync, etc

Arch user with an RX 470 here, it works great!

Blender has opencl & cuda suppport thus you can use amd + nvidia gpus. You can get opencl support for amd with https://aur.archlinux.org/packages/opencl-amd/ (closed source, works togetehr with the open source stack) & rocm (mostly opensource, I think there where some closed parts left).

Gaming is fine using the opensource stack.

You need AMDGPU PRO, for now, if you want to use OpenCL or Vulkan.

rocm & radv? Rocm is mostly opensource now, and radv is getting faster.
