    Phoronix: Linux 6.7 Set To Drop Support For Itanium IA-64

    Since 2021 the Itanium IA-64 code was orphaned in the Linux kernel and over the course of this year there's been talk of retiring the Itanium code from the kernel, a.k.a. strip it out. It looks like 2023 will end with the Itanium IA-64 code indeed being removed from the Linux kernel...

    The last remaining Itanium user is shaking right now.

        dlq84 last produced Itanium CPU were made in 2017 that I can find. I could say some of the last Itanium buyers might be having a very bad case of buyers remorse.

        Also note they are 2017 chips but they are also only 32nm

        x86 processor from intel of 2017 is 14nm.

          I'm surprised Intel could find a way to sell them for that long.

            IIRC, they were contractually obligated to for HP.

              The last Itanium buyers have a bad case of buyers remorse ever since the first x86-64 CPU was launched by AMD, since it immediately became apparent that Itanium wouldn't be the 64-bit successor to x86, despite being designated as such by Intel.

              But unfortunately they were stuck with OSes that required Itanium such as HP-UX and OpenVMS, so Intel had to keep making Itanium CPUs for HP under contract. Once the contract was over, Intel stopped making them.

              Personally, I am glad this single-vendor architecture (and patented to the teeth to remain that way) is dead. Goodbye and good riddance.

                Kinda makes me wonder how much HP benefitted from the IA-64 contract. I'm guessing Intel put very little investment in improving the architecture; I wouldn't be surprised if they basically just upgraded the node, gave it some higher clock speeds, maybe thrown in a little more cache, and sold it for a massive profit. Since there was effectively only one customer, Intel had no reason to market this or have retail models, which would have only further increased their profit margin. Intel would only have to produce as many as HP requested, which meant Intel would have no leftover inventory.
                So, it all came down to being just HP dealing with the expenses of keeping this architecture alive. Makes me wonder if it would have been cheaper for them to have just cut out the middleman by buying the architecture and a couple engineers from Intel. Or... if they both mutually agreed to cancel the contract. I figure the few remaining HP customers who use it aren't worth maintaining the architecture, even if HP were to get sued.

                  Intel lost badly on the Itanium. They could not just reduce the node size and hope for the best. Performance was so abysmal, especially in x86 compatibility mode that they had to invest massive engineering resources in rebuilding the cpu several times.

                  I am not certain, but I think HP did all right on their side as they pretty much exclusively used Itanium in their non-stop server line where it worked out quite well, even at its lower performance threshold.

                  I think Oracle also got burned in this adventure, weren't they required by contract to keep their database running on Itanium long past its profitability?

                  In the end, I personally liked a bunch of the design decisions in Itanium... but I never had to program for the beast, and am given to understand it was only rivalled by the Cell processor in its abuse of the programmer.

                  They really should have just made Itanium their first "Compute Card" and kept it as an add on to an x86 CPU. There were groups doing this with the Cell CPU at one point (https://techreport.com/news/mercury-...-a-pci-e-card/).
