From e65bdffaf29beb1102c289b6a43675e172903077 Mon Sep 17 00:00:00 2001 From: aurel32 Date: Fri, 17 Oct 2008 08:08:48 +0000 Subject: [PATCH] i386/SVM: return amount of ASIDs With SVM the TLB supports tagging to distinguish TLB entries from different virtual CPUs. This tag is called an ASID. The amount of ASIDs is given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might break hypervisors. Let's better return something >0 here, say 0x10. Since we're flushing the complete TLB on every VM entry and exit we're not making use of the ASID information anyways.
