Re: [vfio-users] amd rx480 invalid rom contents

Unfortunately no, but I have to start the windows vm that uses the rx480 before I can use atiflash for linux. Not sure whether I use the correct terminology, but it seems the bios of the gpu needs to be initialized/loaded before atiflash can access the gpu. If I try to use AtiWinFlash in the

Follow-up on the issues I was experiencing, it looks like they are fixed by a new bios I got from MSI: https://www.techpowerup.com/vgabios/188263/188263 With this bios my PCIe Bus Errors are gone and I don't need to specify the rom file in the xml anymore. Not sure if this is known to ever

Re: [vfio-users] amd rx480 invalid rom contents

Thanks for checking. After adding nohz_full, rcu_nocbs, isolcpus parameters to my grub cmdline and switching to the Ubuntu lowlatency kernel it seems the sound is quite good when playing youtube video's or vlc. No crackles or noise anymore. Not sure if there is really causation with using the

Re: [vfio-users] amd rx480 invalid rom contents

Hmm. No I pass through my usb headset for sound and microphone. Once I adjusted the sample rate in was good to go. I pass through the hdmi audio PCIe device and set the msi interrupt for good measure though I don't actually make use of it. scott On Jan 23, 2017 7:04 PM, "P. Pronk" wrote:

Also for a ich6 sound device? Thought the msi interrupts was a 'pass through' setting when you use the hdmi audio device? Anyway, it's not listed in regedit in the PCI tree as the amd & virtio devices are so not sure what to do. I have to set it to CD quality, any better or worse and the cra

Also I had weird errors initially with my gpu.. turned out my power supply was failing and therefore not providing quite enough power. Got a new power supply and all was well. Just food for thought. scott On Jan 23, 2017 6:40 PM, "Scott" wrote: Change the sample rate in Windows to DVD quality

Change the sample rate in Windows to DVD quality.. that made my sound crackles go away. Also ensure msi Interrupts enabled. scott On Jan 23, 2017 6:24 PM, "P. Pronk" wrote: > > That would be interesting to see indeed. Actually I bought the RX460 > because first I wanted to use my old HD7850, b

Re: [vfio-users] amd rx480 invalid rom contents

That would be interesting to see indeed. Actually I bought the RX460 because first I wanted to use my old HD7850, but then my pc didnt even want to boot (linux, didnt try windows). It just hanged seconds after grub loading with a lot of those PCIe Bus Error's. Then I tried a couple Nvidia NVS

Re: [vfio-users] amd rx480 invalid rom contents

Hi I downloaded a rom from the Internets. There is a common site that has a library of them. I have been meaning to try without the rom file too. Not sure it's necessary. I think you have a tougher time because you have two AMD cards. I am able to blacklist the AMD driver completely because my

Hi, depending on the Polaris being a reference card, the Bios may be actually passed through from AMD itself. Sapphire told me that, when I was complaining about exactly your issue with an RX480 reference card from them. Since I bricked it the first time, I had a reference bios from sysfs, that wa

I have that msi rx480 card working with pass through. Note I had a much easier time using the uefi bios. I am currently specifying a rom file in my XML for my video card but I don't think that's entirely necessary. scott On Jan 22, 2017 12:47 PM, "P. Pronk" wrote: > On Sun, 22 Jan 2017 11:55:5
