Marian Postevca 602b458201 acpi: Permit OEM ID and OEM table ID fields to be changed
Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.

Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).

This patch allows you to override these default values.

The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN

The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.

Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.

This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.
