    i3-5010u without RDSEED and SMAP

    mark9

      Despite what's written in the product briefs my i3-5010u does not have RDSEED and SMAP.

      http://www.mouser.com/pdfdocs/Broadwell_Platform_Brief.PDF

       

      The program I've written crashes, and tools like "coreinfo" and "hwinfo64" don't show it, too. RDRAND works fine.

       

      Is this something my NUC5i3MYHE is still due to receive with microcode along with a new BIOS (I am at v20)?

          I am currently researching on this issue. As soon as I can, I will send you a message with my findings. Thank you for your patience and understanding.

            I have been able to run coreinfo program where I see RDSEED and SMAP as supported features.

            Please attach screenshot when you run Coreinfo.

                Hi mark9,


                I work with allan_intel and I see in your Coreinfo screenshot that RDSEED and SMAP appear as supported.

                Is there anything else you need help with?


                Thanks,

                  Hi rguevara,

                   

                  The screenshot with the red markings is mine. An asterisk indicates that a feature is »supported«, the quad says »not supported«.

                   

                  Still waiting on your input regarding the missing instruction sets.

                   

                  Thanks,

                  Mark

                    Hi mark9,

                     

                    We (Intel Customer Support) are still investigating on your question and we will get to you soon. I apologize for the delay and will post an update as soon as possible.

                     

                    Thanks,

                      Hi Mark9

                      Can you provide information on whether your CoreInfo dump was run inside a virtual machine or on bare metal?

                       

                      I ask this because some of your other red boxes are consistent with typical approaches that VMMs would do in its productization decision on what limitation its Guest OS would have.

                       

                      For example, debug storage is a facility, to my understanding, present in recent generations of processors. However, system utility that would make use of debug storage for profiling present a significant challenge in a virtualized environment. Since VMMs operating on bare metal will emulate CPUID and feed emulated output into its guests, when software in a gues OS executes CPUID. VMM will emulate CPUID (for all features it does not know about or did not wish to support within a guest) as not present.

                       

                      DS not available is likely the result of VMM emulated CPUID reporting it didn't wish guess software to use debug storage, where as absence of RDSEED/SMAP flag could be the result of a VMM not aware of it at the time of product feature freeze of a VMM vendor.

                        Hi sjkuo,

                         

                        I've run CoreInfo and friends on a new, clean, bare-metal installation of Windows 8.1 pro. I've enabled virtualization support in the BIOS, though.

                         

                        I've not been contacted in the meanwhile privately to provide the serial number of production date of the device. No advance exchange happend to obtain the NUC in question from me. The distributor has told me she/he has not been approached by anyone well-known with the intent to pull a sample from the lot, too.

                         

                        Due to me not having another NUC for comparison I've reached out to the press to obtain comparisons and our findings are currently those: the i3-5010u has RDSEED and SMAP (etc.), the instruction sets are missing on some NUCs, though, all of them having in common that they are run under Windows—which could be a coincidence due to few compared samples.

                         

                        Thanks,

                        Mark

                          I've decided to return the NUC.

                            Hi mark9,          

                             

                            I am sorry to hear that you returned the NUC and I really apologize for any inconvenience around the purchase of this product.

                            I hope that you could give us a second chance in the future.
