    Phoronix: Red Hat Recommends Disabling The Intel Linux Graphics Driver Over Hardware Flaw

    It's been another day testing and investigating CVE-2019-14615, a.k.a. the Intel graphics hardware issue where for Gen9 all turned out to be okay but for Gen7 graphics leads to some big performance hits. Besides the Core i7 tests published yesterday in the aforelinked article, tests on relevant Core i3 and i5 CPUs are currently being carried out for seeing the impact there (so far, it's looking to be equally brutal)...

    That is a pretty significant cut in performance. Effectively no GPU acceleration at all. The security impact must be greater than first imagined if RedHat suggest this.

      Renoir can't come soon enough. This is getting ridiculous.

          Next time I will just disable my entire computer over too many flaws.

          This is ridiculous for real :<

            The funny thing here is that I spent the last two years with my older ryzen based laptop getting faster and faster as new updates came out. In fact I'd have to say that the drivers are now pretty good and kernel support is close to complete. To put it another way most of the grief of the bleeding edge has passed. I'm expecting Renoir to be even better.

            So much better in fact that I'm seriously considering an early upgrade. The only thing it will not be is an HP! HP BIOS support sucks and their batteries simply don't last and are hard to replace. To that end I'm looking for a model/manufacture that builds decent hardware and actually supports it.

              Does this mean I can't play Crysis on RHEL any longer? If true it's a huge bummer.

                RH did not use the word recommend, but used the word mitigation. That is common in the security space where one can mitigate against the vuln until patches/fixes/process can be applied.

                  You'd have to run a malicious binary anyway, which can already do whatever it wants, and far worse than the end result of this.

                    ​​​​​Its the opposite case, if it was important enough it would be fixed on 0 day, it's not a major problem but you do want to mitigate it then disable i915 for now. Its not a recommendation for normal users.
