Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=master 2026-11-12T23:28:16+00:00 2026-11-12T23:28:16+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-11-12T23:28:16+00:00 urn:sha1:800c108f9d2463066a221a0e4ff56867304551a6 - cycle-r1780.sh: load vfio modules one per modprobe (the multi-module form was silently treating the extra names as parameters and never loading mdev); auto-detect the vgpu mdev type and prefer the 2 GiB type used by the campaign. - sdl_cap.c: gate capture-file creation to processes that can actually read GL pixels (a child was truncating the capture), and log the capture pid/pointers. - gz_pbuf.c: LD_PRELOAD shim that gives an SDL2 GL client a GLX pbuffer context on the guest's NVIDIA X server (the proven gl_frames path), with SDL_GL_GetDrawableSize/SwapWindow interception.
