![]() Learn how to accurately convert your PDF files (and Postscript) to various EDA/manufacturing formats no one thought was possible. While such emulators can be run as normal Windows or Linux tasks, speed improves when they can bypass the host OS.Convert any PDF (or Postscript) to Gerber, GDSII, NC, and more! This is often needed by developers to create software for dissimilar hardware that doesn’t yet exist, so the software will be ready for the hardware launch. There is also the edge-case of running VMs for dissimilar CPU architectures, such as running an ARM VM on an x86 system, generally facilitated by emulator tools such as QEMU that do not run under Hyper-V. ![]() There likely will still be cases where only a non-Hyper-V VM will do, such as running non-Hyper-V VM images created by others. One important difference between WSL2 and VMs (like VirtualBox, KVM, Xen, etc.) is that WSL2 uses only Hyper-V, while third-party VMs can use other hypervisors. (Oh, Lord, may I never again have to configure VLANs under Win10. The advantages of WSL2 include gaining access to the Linux kernel’s advanced networking capabilities and direct hardware access via Linux device drivers, especially USB devices and disks with non-Win10 filesystems. WSL2 seeks to eliminate these inefficiencies, though it does impose others. However, such convenience has costs, and WSL1’s adaptation layer imposes multiple inefficiencies and slowdowns, most notably a high cost for filesystem access. I find WSL1 to be very friendly, great for having Linux close at hand without the need for any high-level administration or system partitioning. The WSL1 adaptation layer doesn’t cover all the Linux kernel APIs, but it covers 99.9% of common use. At the very lowest level, WSL1 tasks *are* Win10 tasks, though this level is below that seen by Windows’ Task Manager. WSL1 cleanly shares CPU and memory with Windows, while WSL2 needs cores and memory to be partitioned between Windows and Linux (though this limitation may ease with planned Win10 changes).Īn advantage of WSL1 is that all processor and memory resources are dynamically shared between WSL1 and Windows. (It is technically possible under the initial WSL2 release, but doing so is a bit clunky.) Initially, it may be best to use separate installations of a desired Linux distro for WSL1 and WSL2, then configure them for a shared userspace.Įach WSL version has its advantages and limitations. While it may not be part of the initial WSL2 release, it will be possible to switch an installed Linux instance between WSL1 and WSL2 as needs dictate. Both WSL versions will be retained and maintained going forward. While the original WSL (now called WSL1) uses a compatibility layer (much like Cygwin, though truly integrated with the OS), the newer WSL2 (rolling out now) uses a very lightweight VM that runs a Real Linux Kernel.
