sifting through ACPI 3.0a I just noticed a bit (3)
in the FADT boot_flag to indicate the platform
does not support MSI.

Has anybody noticed fadt.boot_flags bit 3 set on their box?

thanks,
-Len

Would we observe that in kernel boot messages or by using
acpidump?

Using the acpitbl script attached:

# cat /proc/acpi/fadt |acpitbl |grep IAPC_BOOT_FLAGS
IAPC_BOOT_FLAGS:  0x0003

(this example has bit 0 and 1 set, we are looking for bit 3).

If you have an acpidump output, you can do it this way

$ acpixtract FACP acpidump.out | acpitbl | grep IAPC_BOOT_FLAGS
IAPC_BOOT_FLAGS:  0x0003

Implementing that is on my todo list. We definitely should.
