2015.RDSEED is similar to RDRAND and provides higher level access to the entropy hardware.The RDSEED generator and processor instruction rdseed are available with Intel Broadwell CPUs and AMD Zen CPUs. Intel在IVB架构的第三代CPU酷睿处理器(2012年开始生产)内置了一个利用电阻热噪声取得硬件真随机数的...
12. RdRand and RdSeed Instructions in x86 CPUsDavid Johnston
AMD cpu's from family 15h and 16h fail to produce random numbers using RDRAND after a suspend/resume. While first reported in 2014, AMD did not diagnose and offer a patch until late 2019. Also see the following bug reports and patches. Kernel bug: https://bugzilla.kernel.org/show_bug...
Binutils provides the assembler, and that is what produces rdrand or rdseed instructions. (I'm going back a while, so the Binutils version numbers may be off). For RDRAND and RDSEED on Unix and Linux, we found it easiest to emit the byte codes. That sidesteps both the compiler and ...
