----------
- 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.
