[Qemu-devel] How to use -acpitable to add a SLIC-table?

[Stefan Hellermann]

Hello,

how can I use the -acpitable parameter to add a SLIC-table to the
qemu-bios dynamically?

I think I need a file with the SLIC-data, but how can I extract this
data out of my BIOS from my host-machine for example?

The -acpitable parameter accepts a bunch of settings and a datafile, do
I need to set all these settings? I think most of them should sit in the
SLIC-file.

I tried using SLIC-Data-files downloaded from the web, but I'm unsure if
they are formatted correctly.
-acpitable data=SLIC.aml or SLIC.bin doesn't throw an error, but the
linux-kernel in the virtual machine doesn't detect new acpi-tables. I
attached a hexdump from these two files.

I read the commit to qemu to add support for -acpitable (SVN 6650), but
I don't know enough about qemu/pc-bios/programming to get any clue out
of this.

Thanks for your time! Your doing great work!
