问题描述
我的问题是在题材:当我们读的/ proc内/ cpuinfo
Android上的虚拟文件,它包含串口
领域。什么是价值?是相同的为使用同一CPU型号的所有设备,或者它是每个CPU实例是唯一的?
我有GT-I9500(三星Galaxy S4)手机,而其串行最后8个字符是 4d00a804
(修订 000A
)。也许任何人都可以写他的最后8个字符相同的模式来检查它们是否独一无二?
My question is in subject: when we read /proc/cpuinfo
virtual file on Android, it contains Serial
field. What is the value? Is it the same for all devices that use the same CPU model, or it is unique for each CPU instance?I have GT-I9500 (Samsung Galaxy S4) phone, and its serial last 8 characters are 4d00a804
(revision is 000a
). Maybe anyone can write his last 8 characters for the same model to check if they are unique?
推荐答案
串口
是一定数量的可选引导加载程序通过,无关与CPU。如果设置,内核将其视为唯一的设备。
Serial
is some number optionally passed by the bootloader and has nothing to do with the CPU. If set, the kernel treats it as unique for the device.
我有没有设置序号几个设备( 0000000000000000
)和ARM64和非ARM设备不具有串口
在所有。
I have several devices with unset serial number (0000000000000000
) and ARM64 and non-ARM devices do not have Serial
at all.
