Hi, You also mentioned qemu in the description, I think what is related (by title and it has your name) is the following series + one fixup:
77280d33b s390x: fix build for --without-default-devices 37fa32de70 s390x/pci: Honor DMA limits set by vfio cd7498d07f s390x/pci: Add routine to get the vfio dma available count 7486a62845 vfio: Find DMA available capability 3ab7a0b40d vfio: Create shared routine for scanning info capabilities 408b55db8b s390x/pci: Move header files to include/hw/s390x 53ba2eee52 linux-headers: update against 5.10-rc1 84567ea763 update-linux-headers: Add vfio_zdev.h That is in qemu 5.2 - and if that "is it" then in Hirsute things are already fixed by now. But that is quite a list and for backports we will need to reduce that to the minimum that is needed. Did you check if you can (or have even a branch somewhere) backport these on top of 4.2 and/or 5.0 ? Also if this shall be an SRU we would need a testcase, is there anything that can be isolated as test instructions? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
