------- Comment From mjros...@us.ibm.com 2021-02-11 09:37 EDT------- No problem, I suspected this was the case but wanted to be sure.
So, I've run verification on both focal and groovy using the qemu available in -proposed. With the caveat that for focal I used Frank's kernel build provided in 1907421 as we're still waiting for the backport from upstream stable on that for focal. On both focal and groovy, I created a guest with a vfio-pci passthrough mlx device on s390x and forced data-transfer workloads that could, prior to this fix, quickly and reliably overrun the DMA space and result in transfer stalls / QEMU error messages. No more errors -- looks good! ** Tags removed: verification-needed-focal verification-needed-groovy ** Tags added: verification-done-focal verification-done-groovy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913395 Title: [UBUNTU 21.04] qemu s390x/pci: Honor vfio DMA limiting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1913395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
