ACPI FADT reports missing 8042 keyboard under qemu

[stdcall]

Hi.
I started working on keyboard driver, and for starters I would like to detect the existance using ACPI FADT table.
It appears that the 8042 flag is marked as 0 - missing.

I'm using qemu-system-i386 for testing, with no specific configuration. is the problem is in qemu configuration ?

Have you checked that that field is valid in that table? If the table is of an earlier version, the field should be assumed to be "true"

According to ACPI documentation, the 8042 is valid since V2. however I didn't find any reference in the FADT table to the current table version.
Where does the FADT version is written ?

[stdcall]

Found it. silly me.

That was indeed the problem. FADT is version 1.
How come it's so old ? FADT is now at version 5. Qemu doesn't support later versions ?

It doesn't need to - All the information qemu needs to provide is within the v1 structure - so it's a waste of space to provide the larger versions.
