Leaving eclairvoyant's comment pinned because it contains some useful information.
Patch policy is different, but similar.
- Primary purpose of this package are the ACS override and i915 VGA arbiter patches.
- Upstream Arch patches will be applied to maintain parity with the standard kernel.
- No other patches will be added.
Package does have options that can be changed, like building with clang or disabling Arch patches.
- Defaults will match Arch packages, except when incompatible with this package's primary patches.
- Options are subject to change. Read PKGBUILD for details.
Avoid commenting and flagging at the same time for the same issue.
- Flag for common issues with standard solutions, like new releases, key changes, etc.
- Comment for issues requiring explanation or debugging.
  - Use a pastebin for blocks of text more than a few lines.

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

Bypassing the default IOMMU grouping by overriding PCIe ACS support, and
Enabling VGA arbitration support on Intel iGPUs.

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).

Ah, whoops.. I had reorganized the patches to make the diffs smaller and forgot to re-hash. I'll fix that asap, but in the mean time you can update the sha256sum lines in the PKGBUILD. Just run 'sha256sum *.patch' to get the new ones. The sum array has the hashes in the same order as the sources array.

Thanks for you time and work... :-)

I receive this : ==> Validating source files with sha256sums... archlinux-linux ... Skipped config ... Passed add-acs-overrides.patch ... FAILED i915-vga-arbiter.patch ... FAILED ==> ERROR: One or more files did not pass the validity check!

Tried to delete the files and re-download , happen the same.

Alright, everything seems to be working on 5.5.3.arch1. I had switched to .3 because I noticed yesterday .4 was still in -testing.. but now .4 is out. This should just work with 5.5.4, you'll just need to change the PKGBUILD pkgver line. The patches apply cleanly. I'm compiling it now for 5.5.4 and will report back with results.

For now, enjoy 5.5.3.arch1: https://github.com/slowbro/linux-vfio/tree/v5.5.3-arch1

(Note: I make no guarantees, minimally tested,etc. My IOMMU groups are identical with this as they were with 5.3.7-arch1. I was able to boot my windows VM and it worked.)

alegru commented on 2020-02-16 13:57 (UTC)

I backported the changes to the linux-vfio-lts package, if someone wants to use it in the mean time

slowbro commented on 2020-02-15 20:31 (UTC)

I've been working on a PKGBUILD based on 5.5.4-arch1. I got the patches re-worked for all the recent intel_vga changes, and things seem good, I'll update later this weekend with a yay/nay.

arkaid commented on 2020-02-14 11:09 (UTC)

Does anybody know of a good tutorial on how to apply the patches by hand?

I usually rely on markzz to update the package, since I don't know how to do it myself, but I need to update the kernel soon.

@aknarts This kernel is too out of date to work with most up to date dkms modules now.

aknarts commented on 2020-02-12 20:42 (UTC)

Anybody has an elegant solution to "incompatible gcc/plugin versions" when building dkms modules(namely nvidia-dkms)?

JuniorJPDJ commented on 2020-02-03 07:11 (UTC)

Don't worry. I'm just making sure you remember :D

markzz commented on 2020-02-03 06:10 (UTC)

I only forgot a little bit. I did some traveling over the last week and didn't have time to get to it. I will make every attempt to get to this in the next week, but sometimes life gets busy.
