报错部分代码 /* Address translation instruction */ static void guest_at(void) { uint64_t par; asm volatile("at s1e1r, %0" :: "r" (guest_test_memory)); isb(); par = read_sysreg(par_el1); /* Bit 1 indicates whether the AT was successful */ GUEST_ASSERT_EQ(par & 1, 0); } 看起来是刷新guest_test_memory对应的的TLB缓存时出现异常
请优先确认 6.6.25-2.1 版本是否存在相同问题
