[kvm-devel] [PATCH] SVM: fix lazy FPU switching

2008-01-21 Thread Joerg Roedel
If the guest writes to cr0 and leaves the TS flag at 0 while vcpu->fpu_active is also 0, the TS flag in the guests cr0 gets lost. This leads to corrupt FPU state an causes Windows Vista 64bit to crash very soon after boot. This patch fixes this bug. Signed-off-by: Joerg Roedel <[EMAIL PROTECTED]>
