Needed for repeating instructions with execution functions. Signed-off-by:

So they can reference execution functions. 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:

Now that the group index no longer exists, the space is free. Signed-off-by:

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

Avi Kivity authored
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:

Avi Kivity authored
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 implements the emulations of the svm next_rip feature in the nested svm implementation in kvm. 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:

Now that we have the host gdt conveniently stored in a variable, make use of it instead of querying the cpu. Signed-off-by:

Use just one group table for byte (F6) and word (F7) opcodes. Signed-off-by:

Avi Kivity authored
Opcodes F6/2, F6/3, F7/2, F7/3. Signed-off-by:

Move operand decoding to the opcode table, keep lock decoding in the group table. This allows us to get consolidate the four variants of Group 1 into one group. Signed-off-by:
-
Avi Kivity authored
Allow bits that are common to all members of a group to be specified in the opcode table instead of the group table. This allows some simplification of the decode tables. Signed-off-by:
-
Avi Kivity authored
Add a decode flag to indicate the instruction is invalid. Will come in useful later, when we mix decode bits from the opcode and group table. Signed-off-by:
-
Avi Kivity authored
Currently group bits are stored in bits 0:7, where operand bits are stored. Make group bits be 0:3, and move the existing bits 0:3 to 16:19, so we can mix group and operand bits. Signed-off-by:
