[Qemu-devel] KVM minutes for 2013-06-11

[Juan Quintela]

----------

- move ACPI table generation to QEMU
  - code sharing with SEABIOS
  - easier to generate there
    Anthony: it is the same put in QEMU or SEABIOS

    Michael: there are some information not easily available in
    seabios (hot plug)

    Anthony: transfer QOM tree to SEABIOS,  current interface shows its age.

  - information hardcoded that change over time
    this is easier in qemu

  Example bus device number:
    maintain device number stable over migration

  It is easier to maintian the mostly static tables in QEMU.

  QEMU knows the whole device tree,  so it is easy to generate.

  Where are we know?  Do we have enough ACPI support into QEMU?
  Anthony wants a mergable tree before starting.  Still think it is the wrong 
approach.
  Create a new serial port and enable it through ACPI?

  Using iasl at roon time and source table is problematic.  iasl don't
  work on big endian hosts.

- VFIO?
  How to do it (Alex),  will be discussed on the list

Later,  Juan.
