Currently we use a void pointer for memory addresses. That's wrong since these are guest virtual addresses which are not directly dereferencable by the host. Use the correct type, unsigned long. Signed-off-by: -

Let it compute modrm_seg instead, and have the caller apply it. Signed-off-by: -

Introduce spte_has_volatile_bits() function to judge whether spte bits will miss, it's more readable and can help us to cleanup code later Signed-off-by:

It's a small cleanup that using using kvm_set_pfn_accessed() instead of mark_page_accessed() Signed-off-by:

Instead of looking up the opcode twice (once for decode flags, once for the big execution switch) look up both flags and function in the decode tables. Signed-off-by:

It doesn't ever change, so we don't need to pass it around everywhere. Signed-off-by:

Instead of having a group number, store the group table pointer directly in the opcode. Signed-off-by:

We'll be using that to distinguish between new-style and old-style groups. Signed-off-by:

Once 'struct opcode' grows, its initializer will become more complicated. Wrap the simple initializers in a D() macro, and replace the empty initializers with an even simpler N macro. Signed-off-by:
-
Avi Kivity authored
This will hold all the information known about the opcode. Currently, this is just the decode flags. Signed-off-by:

The parenthese make is impossible to use the macros with initializers that require braces. Signed-off-by:

Ths patch adds IRET instruction (opcode 0xcf). Currently, only IRET in real mode is emulated. Protected mode support is to be added later if needed. Signed-off-by:

This patch fixes a bug in a nested hypervisor that heavily switches between real-mode and long-mode. The problem is fixed by syncing back efer into the guest vmcb on emulated vmexit. Signed-off-by:

After commit 53383eaad08d, the '*spte' has updated before call rmap_remove()(in most case it's 'shadow_trap_nonpresent_pte'), so remove this information from error message Signed-off-by:
