| * | tools: cycle-r1780.sh arms the GR lane per boot (rm-call ladder + guest-ram ↵ | Arthur Hanson Rasmusson | 2 days |
| | | | | | | | | | | | | | | | | | | | | | | | activation) Post-reboot cycles lost the pre-reboot 'arm the GR lane' steps, so gsp_phys_backend_gr_ready() stayed false (rmcall_gr_exec_ok=false) and every captured GL section died SILENTLY at svc_gr_request's first gate (c198: work_gr req=73 fallback=73 ok=0 refused=73 submitted=0 exec_ok=0; an ftrace run counted 2282 silent svc_gr_request calls). After 'guest agent up' the cycle now runs, with warnings only (never fails the cycle): echo 5; echo 3; echo 4 > gsp-phys-rm-call (order matters; 4 alone fails by design) echo '<mdev> /dev/shm/vgpu-guest-ram 0x80000000 0x0 0x300000000' > gsp-phys-guest-ram and logs both to <tag>-ladder.txt. Validated c203: 7x 'GR LAUNCH submitted' + 5x 'GUEST GR LAUNCH OK' from the captured GL sections (zero ever before), exec_ok=1, work_gr ok=4 backend_ok=4. Residual: gl_frames still black - GR-DEC n_data=0 dropped=24 (the section's data window resolves empty) and 'sema-grce: owner-vas h=0xbeef0100 ... dst=0x120700000 unmapped; cross-VAS walk refused (client-private page)' for the client copy-out operand - the old n_data/dstpend frontier, now with the forward live. | ||

| * | tools: fix r1780 cycle prerequisites and add SDL GLX-pbuffer shim | Arthur Hanson Rasmusson | 3 days |
| | | | | | | | | | | | | | | - 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. | ||
