This package exists for the specific purpose of adding ported patches based on those originally created by Alex Williamson for:

Arbitrary patches will not be added.

Refer to the wiki on PCI passthrough and this blog post on IOMMU groups for risks/caveats before using this package.

Regular AUR etiquette applies as well (knowledge of makepkg and searching the wiki/Arch forums is expected, and AUR helpers or Arch-based distros that are not Arch Linux are unsupported).

ShayBox, it's unfortunately just the one little server on the west coast; it was probably busy with the binge watching I was doing on Plex last night. Should be okay now?

I'm going to set up my build system again and keep this package up to date as regards to this PKGBUILD to keep it up to date on my repository. The 5.5.13.arch1-1 is built and up on my repository.

markzz commented on 2020-03-28 04:41 (UTC)

This is my queue to actually use my work from home time and compile a new version of the package.

slowbro your repo is running at a few hundred kbps

slowbro commented on 2020-03-27 18:23 (UTC)

Sorry for the update delay; I had made 5.5.10, but then forgot to push it. Then work-from-home happened and things have been cuh-ray-zee.

5.5.13 is up now. If anyone is using my repo, as an FYI, I have switched to zstd (.tar.zst).

I hope everyone is doing well.

Got 5.5.9 out; note that this kernel is compiled w/ gcc 9.3.0; you may need to pacman -Syu before building the new version (I'm not entirely sure since I did a roundabout way). Either way, the pre-compiled version is available on my repo.

And now my graphics card I've attached for use with VFIO isn't initializing correctly. Looking deeper it seems like this is a kernel issue, but I don't know the cause. Looking through dmesg, I get this: pci-stub 0000:07:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff and some message saying it couldn't turn on the device. Is anyone else having these problems? I'm building the LTS version of this kernel in the hopes it fixes my problems. I'll edit my post as I find more information.

EDIT: I should mention that it's not the card itself since I booted into Windows 10 briefly with it and it appears to work fine.

osakasys commented on 2020-03-14 18:51 (UTC)

Seems my build wasn't working. If I use slowbro's build it works fine.

markzz commented on 2020-03-14 18:31 (UTC)

Did you try the regular arch kernel? This patchset does not touch anything regarding disk mounts.

osakasys commented on 2020-03-14 14:51 (UTC) (edited on 2020-03-15 15:13 (UTC) by osakasys)

Getting an error when using fusermount: fuse: missing mountpoint parameter

Everything I can find points to this being a kernel issue.

EDIT: This may be fixed in 5.6 due to this commit
EDIT2: This problem seems to have been fixed by using slowbro's build. I think my gcc and gcc-libs versions may have been to blame.
