The Linux kernel traps certain reserved instruction exceptions to emulate the corresponding instructions. QEMU plays the role of the kernel in user mode, so those traps are emulated by accepting the instructions. This change adds the function check_insn_opc_user_only to signal a reserved instruction exception for flagged CPUs in QEMU system mode. The MIPS III instructions DMULT[U], DDIV[U], LL[D] and SC[D] are not implemented in R5900 hardware. They are trapped and emulated by the Linux kernel and, accordingly, therefore QEMU user only instructions. Backports commit 96631327be14c4f54cc31f873c278d9ffedd1e00 from qemu |
