PiMaker101: One of the goals of this package is to model it after the standard linux package in the official repositories. This includes configuration options. This does not, however, stop you from changing the config yourself when you build it though.

Tested with 5.0.9 by changing the git tag in the PKGBUILD, working fine, including testing with QEMU 4.0. Noteworthy though, that I had to disable building the doc package (removed htmldocs from make
), since there was a build error with sphinx.
By the way, I think it might be a good idea to change the default kernel config in this package to enable voluntary preemption (CONFIG_PREEMPT_VOLUNTARY=y
), since this fixes a bug with QEMU/OMVF boot times when configured with a lot of RAM/cores (see https://forums.unraid.net/topic/72172-unraid-os-version-653-available/). Personally using this configuration, have not noticed any side-effects or performance losses on the host so far.

Just wanted to say that In regards to jmandawg and markzz that I have been updating by just changing the versions for about a week now (starting with 5.0-1) with no unexpected behaviour or side effects. Although I should state I haven't done any deep testing outside of just running my normal vms etc.

jmandawg: You can certainly try just changing the PKGBUILD with no new patches, but I would bet on the fact that the current patches will not work. The issue is, it's on my list of things I have to get done, but that list has grown in the last few months to the point where I'm trying to catch up. No ETA at this moment.
EDIT: I take it all back, it looks like the patches did apply, so I'm running a build and will quickly test it tomorrow.

Thanks for the great work, 5.0.x coming anytime soon? Or is it safe to change the _srcver and rebuild?

The latest version (4.19.8-arch1-1-vfio) has build error due to patch:
drivers/pci/quirks.c:4617:28: error: ‘pci_acs_overrides’ undeclared here (not in a function); did you mean ‘pcie_acs_overrides’? { PCI_ANY_ID, PCI_ANY_ID, pci_acs_overrides }, ^~~~~~~~~~~~~~~~~ pcie_acs_overrides

I have pushed something that the patches apply, but I haven't tested the package itself.

You shouldn't have any troubles using the patch in your sources for 4.19.8. Built and tested it myself with linux from the core repo. If you'd like, I can help keep this maintained.

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).
