cpuinfo序列号是固定的问题
Posted: 2025-06-23 0:11
我有几块Lyra 3506，/proc/cpuinfo的serial是固定的2a9dfd2363bcabd0，而内核dmesg的serial是随板子不一样而变化
是内核没适配吗？

@ -952,7 +952,7 @ static int __init init_machine_late(void)
system_serial = NULL;
}
- if (!system_serial)
+ //if (!system_serial)
system_serial = kasprintf(GFP_KERNEL, "%08x%08x",
system_serial_high,
system_serial_low);
