Tsirkin" Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" Hello, We recently found out that some softwares are effectively crashing when they detect qemu's `OEM ID` or `OEM table ID` in the ACPI tables. I see no reason not to expose the setting to the user/command-line. A previous patch has been submitted in 2015[1] but did not get through because (if I understand correctly) using the IDs on the `SLIC`, `BXPC` and `RSDT` tables were enough at the time. If you agree, I am willing to forward port the patches of M. Jones but I need to ask how it would work `Signed-Off`-wise ? Thanks in advance for your time, PS: the softwares will crash if the signature is found in any of the exposed tables.
