    Braswell CPU (Cherry View)

    isndw

      Hallo, i have an intel celeron n3150 cpu. According to my kernel output on linux he has as cpuid 406c3. I followed the microcode update guidance, there should be already a new microcode update 00000367/00000410. But this update is not included in the new microcode data file from 12.03.2018 ...

       

      So i would like to know if there will be this month or in the future a new microcode data file with all cpus included which are mentioned in the microcode update guidance as updated? And if not, have the vendors of the motherboard access to this updates?

          Thank you very much for contacting the Intel Communities Team, isndw.

          Please find the link to Microcode Revision Guidance of March 6, 2018, where the CPUID of your processor is mentioned: https://newsroom.intel.com/wp-content/uploads/sites/11/2018/03/microcode-update-guidance.pdf
          In this case, I recommend you to double check with your OS support and the manufacturer of your system if they have an update for this vulnerability issue.

            Thank you for your answer. As i mentioned in my post i had already checked the microcode update guidance. My os is ubuntu 16.04 and there the microcode has been already updated, so the newest microcode is applied. The problem is, in the microcode of 12.03.2018 is my cpu not included:

             

            https://downloadcenter.intel.com/download/27591/Linux-Processor-Microcode-Data-File?product=87258

             

            So, the problem is not the operating system or the manufacturer, because they have also to wait for intel to deliver the microcode and the microcode for the n3150 is not delivered in the newest microcode file in contradiction to the microcode update guidance where the update should be already there.

             

            So, i ask again, because your answer didn't answer my question: Will be there a new microcode file where all updates are included which are mentioned in the microcode update guidance as updated?

                Ubuntu delivered already the updates, but Linux depends also on the microcode file. So if intel dont deliver the microcode upates in the file nothing will happen. Ok, linux has also retpoline, so the situation is on linux not so bad.

                I contacted already the manufacturer, they also told me they have to wait for intel ... so if intel don't deliver the updates nothing will happen.

                 

                The problem was announced in january, now its april ... whats going wrong here? The updates are here but not delivered?

                 

                My next computer will not anymore contain a intel cpu, that is for sure ... now there are more alternatives on the market.

                    Here, i can show you, in this file is not the update as mentioned in the microcode revision guidance:

                     

                    microcode-20180312$ iucode_tool -tb -lS ./intel-ucode

                    iucode_tool: system has processor(s) with signature 0x000406c3

                    selected microcodes:

                     

                    The output shows, for the selected processor 0x000406c3 is no update included. But in the microcode revision guidance is this mentioned:

                     

                    Cherry View (Cherry Trail, Braswell) Intel® Atom® x5-Zxxxx CPU 406C3 01 Production --- --- 00000367

                    Only this processors got a update in the last microcode update file from intel (microcode-20180312.tgz):

                     

                    microcode-20180312$ iucode_tool -tb -l ./intel-ucode

                      Thank you very much for your reply, isndw.

                      The only information we have available at this moment is the one I shared with you above. If your processor is not having this update yet it can be that either your processor was not affected or the update it has not been provided or achieved with your mainboard manufacturer. Please keep an eye on the links I attached and on the newsroom.intel.com for any update on this vulnerability issue.

                        "If your processor is not having this update yet it can be that either your processor was not affected"

                         

                        If you ever read my comments you should know that my processor is affected.

                         

                        "or the update it has not been provided or achieved with your mainboard manufacturer"

                         

                        If you ever read my comments you should know that there is a update but the update is not in the microcode data file.

                         

                        It is not the responsibility of the manufacturer to deliver a update, it is the responsability of intel because intel produced a bad product. The manufacturer can only deliver updates if intel delivers updates. And the microcode data file only shows that intel did not deliver the updates. So intel providing fake news if they tell us they have updates but they don't deliver them and in the  microcode revision guidance they tell that there is a update.

                         

                        So in the future i will never by a intel product again, the future lie in arm processors.

                          Well,  in the future, when you are not buying Intel products, consider that the other manufacturers have issues as well:

                          https://www.techarp.com/guides/complete-meltdown-spectre-cpu-list/

                           

                          And, nothing is immune from future hacks - nothing.  So, throw a tantrum if you must.

                            It is not about that one product is better then an other ... there will be in the future other security problems. It is about how intel manage them and will manage them in the future. Intel was informed about meltdown and spectre already last year and had long time to react. They inform the customers that there are updates, but there are no updates. How intel handels their customers is the problem. I am not the only one who is disappointed from intel:

                              You should do whatever makes you happy.  Since you are not happy here, perhaps someplace else will provide you with what you need.

                                I only hoped to get answers here ... intel does not provide a other way ...

                                  I had the same issue for my Atom x5-Z8300 based Linux system. Eventually, I found the microcode file I needed from a user in the BIOS modding community. It has presumably been extracted from some OEM's BIOS update. That doesn't matter though as the file should be identical to what Intel could've released publically.

                                   

                                  I've renamed them in a way that gets picked up by the intel microcode update facility provided by the intel-microcode package in Debian/Ubuntu and presumably the equivalent packages in other distributions as well. Just put the appropriate file in /usr/share/misc/ and update your initramfs by running "sudo update-initramfs -u".
