Subject: [Qemu-devel] Why Qemu doesn't present L3 cache info for guest?
Date: Thu, 25 Aug 2016 15:09:27 +0800	[thread overview]
Message-ID: <57BE99A7.2060005@huawei.com> (raw)

Hi guys,

Looking at the codes, for pc-2.4 machine it enables host-cache-info for
guest so guest can get the L3 cache info of host. But since QEMU has its
own rule to generate ACPI ID, guest will not use the L3 cache correctly.

I also notice that QEMU present L1 and L2 cache for guest via its own
rule, why it not present L3 cache info which is consistent with the ACPI
ID? Are there any downsides?

Thanks,
