Does qemu support SapphireRapids-V4 CPU, such as Intel Xeon Gold 6430?

It’s well known that SapphireRapids-V4 supports user-mode interrupts (uintr). Although my host system with an Intel Linux kernel can enable uintr, QEMU filters out the uintr instruction set upon startup. What’s more, when I enforce qemu running with -cpu host,uintr=on, qemu issues an error with Property 'host-x86_64.uintr' not found. Is there any solution to this?”
