       is there already an fpga pcie card that's meant to be programmed while sitting in its host, by its host, and has some facility to pipe i.e. a framebuffer back to the host? i'd like to have this for in-computer fpga emulation (yeah yeah, no semantics please) of retro and other systems. like, in a fun, developer friendly way.

       @mntmn The FPGAs I have seen ("old" Intel D5005, AlphaData 9H7, 9V3) are PCIe boards that can be programmed in-band (pcie) and out-of-band (usb from host to fpga) and can take part in normal PCIe-operations, and, for example, be memory-mapped to an arbirtary place in virtual memory. They also often have hefty (~100G) QSFP slots (for, eg, ethernet). "back-framebuffer" is not the most notorious use case, but I think it is well in scope…

       @mntmn we do that but er the formfactor isn’t exactly standard PC hardware. (Most of the hdl required might be open source, though) @patrislav do you know better?
