Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

Which patch are you referring to? As I already said, it might have been worth trying with the standard kernel. The patch to fix my marvell controllers. Without it and IOMMU enabled, I get loads of IO_PAGE_FAULT errors from the controllers and my graphics card, at most times I can't even boot comple...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

I'm not sure if compiling your own kernel is the best way to go. Have you tried the standard kernel shipped with Linux Mint or Ubuntu? I'm currently at LM16, but have tested LM17 as well. It might be a good idea to check the forum for help on graphics card / GUI issues. I'm afraid I can't be of muc...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

Thanks! I tried it (reinstalling everything without the 2nd graphics card) but in the end, I got the same result. The graphics card is assigned to the pciback driver, but I still can't get an UI working. I added the pci-stub module to the kernel before compiling this time, and will now give kvm a tr...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

Hi again and sorry for not responding for so long :roll: Your kernel command line looks a bit weird. I assume you mean that there are two iommu parameters. I read that somewhere (I don't even know in what kontext it was), probably it was a tutorial for kvm :D but it's not relevant anymore, see below...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

@powerhouse When choosing the normal boot option in grub, all the features seem to be recognized. svm is now in the list of supported features, AMD-Vi as well and IOMMU somehow: ga-990fxa-ud5 boot # dmesg | grep -i AMD-Vi [ 2.017670] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40 [ 2.017673] AMD-Vi: I...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

Thanks for your time and input :) 1. It seems that IOMMU is not supported on my system: ga-990fxa-ud5 opt # xl dmesg | grep -i i/o (XEN) Enabling APIC mode: Flat. Using 1 I/O APICs (XEN) I/O virtualisation disabled 2. I already switched to the xl toolstack as xen told me that xm isn't supported anym...

Re: HOW-TO make dual-boot obsolete using XEN VGA passthrough

Hi, First of all, thanks for this fantastic How-To! Unfortunately, it seems like IOMMU doesn't work on my setup, even though my motherboard and CPU should support it according to the lists of tested hardware in the first post. My setup: Gigabyte ga-990fxa-ud5 running the latest BIOS version; IOMMU i...
