------- Comment From mjros...@us.ibm.com 2021-01-20 09:51 EDT------- Re: the kernel patch to groovy... My understanding is that the window for both 5.8.y and 5.9.y are already closed since they are not LTS releases... The 5.10 window is still open and will be for a while as the most recent LTS -- the fix is already in 5.10.
The upstream 5.10 fix is very close to fitting on groovy. The significant difference with groovy is that vfio_iommu_type1_get_info does not yet exist, so an identical change has to be made in vfio_iommu_type1_ioctl instead (vfio_iommu_type1_ioctl got turned into a switch statement that calls sub-functions by ccd59dce1a21, so code got moved - 5.4 backport needed further changes, but you can see the same sort of accommodation there). I could provide a patch that does this fitting. Or, it looks like upstream ccd59dce1a21 + 7d6e1329652e fits cleanly on groovy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907421 Title: [UBUNTU 21.04] vfio: pass DMA availability information to userspace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1907421/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
