 Agenda

 Discussion

• AJB: mentioned the xen-vhost-master PoC is working

  • SS: is it using the xen libs?

  • VK: yes at the moment, slowly migrating to rust

  • SS: did you need Epams non-upstream patches?

  • VK: yes

  • SS: does this integrate with xl create?

  • VK: not yet, start manually

    • should send out an email tomorrow with details of the repos

  • SS: a bit of automation is missing for the disk

• AJB:

  • sprint planning

• SS: we are going to work on qemu (IOREQ Xen PV on ARM)

  • AJB: the kvm/tcg patches are the disaggregation patches

  • SS: for speed stick to current x86 xen model

  • SS: introduce Vikram

• AB: I have a question about Xen on Cortex-R52

  • SS: we want to port to R52, static partitioning, dom0less

  • SS: linux not really required

  • AB: don’t want to encourage mmu-less linux, please let it die in peace

  • SS: we not planning on it, maybe useful for testing but unlikely for production

  • AJB: is there interest in expanding Cortex-R profile support for QEMU

  • SS: yes, there is interest, talk to Edgar

  • AB: been looking at expanding “virt” support for other CPU types

  • SS: that would be interesting

    • could have virt devices on “random” CPU types

  • AJB: maybe a virtualised test machine for multiple CPU types?

    • AB: kernel support for “Goldfish” machine which does that

    • AJB: is it documented

    • AB: a bit

    • AB: mostly virt with minimal HW where it makes sense
