Why CXL and not generic epci RAM/RAMDISK?
So, why CXL [1] over expansion RAM/RAMDISK card [2]?
[2] fine for rasberry pi 4 (per epci speed)

- rektide 4y agoI presume you mean pci-express (PCIe) ram? "epci" is not a name I've ever seen before, to my recall. CXL should be a generic improvement over PCIe period, for (nearly) all applications, including attached storage and/or ram. It has simpler protocols, designed for lower latency. It has more capabilities: it can be switched, so that multiple hosts can either switch between or simultaneously share a device. Samsung already has a device using an ASIC for attaching DRAM over CXL[1].

- sargstuff 4y agoYeah, 'pcie' search gives better results. Related technical aspects at https://github.com/OpenMPDK/SMDK https://github.com/OpenMPDK/SMDK
