* x86: Workaorund for the KVM GS_BASE MSR save/restore issue.Jun Nakajima2011-05-271-0/+21
| | | | | | | | | | In some versions of the kvm module in Ubuntu, the host's GS_BASE MSR is not save/restored correctly when running guests on 64-bit hosts if the qemu/emulator is 32-bit. This patch implements a workaround in the emulator code.

* x86: kvm: fix KVM build + enable auto-detection.David 'Digit' Turner2011-05-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the build of KVM support in the x86 emulator by copying official Ubuntu Lucid KVM headers into android/config/linux-*/ This removes the need to rely on the build machine's versions of these headers, which caused various issues. Also, by default, the emulator will now probe the system to see if it can start in KVM mode automatically. See android-kvm.c for details. You can see the result of the probing with the -verbose option. IMPORTANT NOTE: It looks like there is a bug in the KVM code when the emulator is built as a 32-bit binary, running on a 64-bit kernel, so we explicitely disable KVM when we detect this case. It's hard to tell whether this is a bug in QEMU or some versions of the KVM driver. As such, KVM only works when building the emulator as a 64-bit program. For now, this is only possible with "android-configure.sh --try-64", not the Android build system. + Add a new QEMU option (-disable-kvm) to explicitely disable KVM if needed. This is an addition to -enable-kvm which already exists (and forces usage of KVM). Change-Id: I6a397cae29ab62b1c56fce95c1ee75a4664d6688
