Allow emulate_pop() to read into arbitrary memory rather than just the source operand. Needed for complicated instructions like far returns. Signed-off-by:Avi Kivity <avi@redhat.com>

Avi Kivity authored
If we've just emulated an instruction, we won't have any valid exit reason and associated information. Fix by moving the clearing of the emulation_required flag to the exit handler. This way the exit handler can notice that we've been emulating and abort early. Signed-off-by: -

The ususable bit is important for determining state validity; don't clobber it. Signed-off-by: -

The vmx guest state validity checks are full of bugs. Make them conform to the manual. Signed-off-by: -

When itlb or dtlb miss happens, E500 needs to update some mmu registers. So that the auto-load mechanism can work on E500 when write a tlb entry. Signed-off-by:

Kernel for E500 need clear dbsr when startup. So add dbsr register in kvm_vcpu_arch for BOOKE. Signed-off-by:

The Book E code will be shared with e500. I've left PID in kvmppc_core_emulate_op() just so that we don't need to move kvmppc_set_pid() right now. Once we have the e500 implementation, we can probably share that too. Signed-off-by:

This is an x86 specific stucture and has no business living in common code. Signed-off-by: -

Certain clocks (such as TSC) in older 2.6 guests overaccount for lost ticks, causing severe time drift. Interrupt reinjection magnifies the problem. Provide an option to disable it. [avi: allow room for expansion in case we want to disable reinjection of other timers] Signed-off-by:Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by:

Since we advertise MSR_VM_HSAVE_PA, userspace will attempt to read it even on Intel. Implement fake support for this MSR to avoid the warnings. Signed-off-by: -

vmap() on guest pages hides those pages from the Linux mm for an extended (userspace determined) amount of time. Get rid of it. Signed-off-by:

VMX initializes the TSC offset for each vcpu at different times, and also reinitializes it for vcpus other than 0 on APIC SIPI message. This bug causes the TSC's to appear unsynchronized in the guest, even if the host is good. Older Linux kernels don't handle the situation very well, so gettimeofday is likely to go backwards in time: http://www.mail-archive.com/kvm@vger.kernel.org/msg02955.html http://sourceforge.net/tracker/index.php?func=detail&aid=2025534&group_id=180599&atid=893831 Fix it by initializating the offset of each vcpu relative to vm creation time, and moving it from vmx_vcpu_reset to vmx_vcpu_setup, out of the APIC MP init path.

Effectively reverting to the pre walk_shadow() version -- but now with the reusable for_each(). Signed-off-by: -

Eliminating a callback and a useless structure. Signed-off-by: -
Avi Kivity authored
Using a for_each loop style removes the need to write callback and nasty casts. Implement the walk_shadow() using the for_each_shadow_entry(). Signed-off-by: -

Limit KVM_CAP_SET_GUEST_DEBUG only to those archs (currently x86) that support it. This simplifies user space stub implementations. Signed-off-by:

The AMD SVM instruction family all overload the 0f 01 /3 opcode, further multiplexing on the three r/m bits. But the code decided that anything that isn't a vmmcall must be an lidt (which shares the 0f 01 /3 opcode, for the case that mod = 3). Fix by aborting emulation if this isn't a vmmcall.

If cr4.pge is cleared, we ought to treat any ptes in the page as non-global. This allows us to remove the check from set_spte(). Signed-off-by: -
Avi Kivity authored
Don't allow a vcpu with cr4.pge cleared to use a shadow page created with cr4.pge set; this might cause a cr3 switch not to sync ptes that have the global bit set (the global bit has no effect if !cr4.pge). This can only occur on smp with different cr4.pge settings for different vcpus (since a cr4 change will resync the shadow ptes), but there's no cost to being correct here. Signed-off-by: -
Avi Kivity authored
Instead of "calculating" it on every shadow page allocation, set it once when switching modes, and copy it when allocating pages. This doesn't buy us much, but sets up the stage for inheriting more information related to the mmu setup. Signed-off-by: -
