H A D | vmm_instruction_emul.c | diff 268701 Tue Jul 15 15:51:18 MDT 2014 neel Add support for operand size and address size override prefixes in bhyve's instruction emulation [1]. Fix bug in emulation of opcode 0x8A where the destination is a legacy high byte register and the guest vcpu is in 32-bit mode. Prior to this change instead of modifying %ah, %bh, %ch or %dh the emulation would end up modifying %spl, %bpl, %sil or %dil instead. Add support for moffsets by treating it as a 2, 4 or 8 byte immediate value during instruction decoding. Fix bug in verify_gla() where the linear address computed after decoding the instruction was not being truncated to the effective address size [2]. Tested by: Leon Dang [1] Reported by: Peter Grehan [2] Sponsored by: Nahanni Systems |
