That is due to the following patch set (originally from tglx) is not
merged yet:
https://lore.kernel.org/lkml/20230621171248.6805-1-xin3.li@xxxxxxxxx/
Sigh, I should have mentioned it in the cover letter.
As mentioned in the cover letter, 2 patches are sent out separately
as pre-FRED patches:
https://lore.kernel.org/lkml/20230706051443.2054-1-xin3.li@xxxxxxxxx/
https://lore.kernel.org/lkml/20230706052231.2183-1-xin3.li@xxxxxxxxx/
Sorry it's a bit complicated.
Got to mention, just in case you want to try out FRED, the current
public Intel Simics emulator has not updated to support FRED 5.0 yet
(it only supports FRED 3.0). The plan is late Q3, or early Q4.
