Subject: snd_intel8x0_inside_vm()
Date: Tue, 18 Feb 2014 19:48:11 -0800	[thread overview]
Message-ID: <5304297B.8050201@zytor.com> (raw)

I just stumbled upon the function snd_intel8x0_inside_vm(), and quite
frankly the code seems bizarre:

        /* detect KVM and Parallels virtual environments */
        result = kvm_para_available();
#ifdef X86_FEATURE_HYPERVISOR
        result = result || boot_cpu_has(X86_FEATURE_HYPERVISOR);
#endif
        if (!result)
                goto fini;

Why don't we simply rely on the PCI SSIDs?
