I noticed also a call to cpu_load_efer() in gdbstub.c, case IDX_CTL_EFER_REG: if (env->hflags & HF_CS64_MASK) { cpu_load_efer(env, ldq_p(mem_buf)); return 8; } cpu_load_efer(env, ldl_p(mem_buf)); return 4; } Should this somehow restricted for user-mode, as it has the potential to set HF_SVME ?
Yeah, it should. Likewise for CR0/CR2/CR3/TPR. Nice catch! Paolo
