Virtualization. FDE. Hot patching. Io Ring (io_uring), etc.
- charcircuit 2y agoWindows 2k already had an io_uring equivalent. That's more of an example of Linux being out of date due to being based off UNIX.
- p_ing 2y agoIOCP, which originated in NT 3.1, is not a circular buffer like io_uring, but both are completion-oriented. Microsoft introduced I/O Rings, more or less a 1:1 copy of io_uring, in Windows 21H1. https://learn.microsoft.com/en-us/windows/win32/api/ioringapi/ https://learn.microsoft.com/en-us/windows/win32/api/ioringap... https://windows-internals.com/i-o-rings-when-one-i-o-operation-is-not-enough/ https://windows-internals.com/i-o-rings-when-one-i-o-operati... https://windows-internals.com/ioring-vs-io_uring-a-comparison-of-windows-and-linux-implementations/ https://windows-internals.com/ioring-vs-io_uring-a-compariso... Windows 8/2012 R2 did introduce Registered I/O for WinSock which is very similar to I/O Rings and io_uring. https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh997032(v=ws.11) https://learn.microsoft.com/en-us/previous-versions/windows/...
- cyberax 2y agoWhere? Completion ports are not an io_uring equivalent. Win11 does have something similar: https://learn.microsoft.com/en-us/windows/win32/api/ioringapi/ https://learn.microsoft.com/en-us/windows/win32/api/ioringap...

- voidspark 2y agoVirtualization is old. I used VMWare on Windows 2000.
- p_ing 2y agoNot used in the same way, see VBS.
- voidspark 2y agoI know VMWare workstation is not the same, but there were VBS-like systems back in the 1970's. IBM pioneered hardware virtualization for isolation on their System/370 mainframes with VM/370 in 1972. VMWare ESX hypervisor brought virtualization to x86 servers (2001). Xen hypervisor introduced open-source virtualization for x86 (2003). By the time VBS showed up, the concepts were already several decades old.
- p_ing 2y agoVBS isn't even the same idea as a full blown VM in a type 1 or 2 hypervisor. I'm not sure why you're attempting to make the comparison.
- voidspark 2y agoI am talking about core concepts, not specific implementation details. VBS uses a hypervisor and hardware virtualization to isolate processes for security. These concepts trace back to systems like the IBM VM/370. Conceptually it's essentially the same thing. The difference with VBS is the scope and purpose of what's being virtualized.
