open-iov.git/tools/guest-diag/guest_mode.sh, branch masterOpen-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers
https://git.vgpu.io/open-iov.git/atom?h=master2026-11-13T01:01:04+00:00vgsp: stop fabricating 0xFFFF into the nvPush error notifier; add r1780 GL ops tooling2026-11-13T01:01:04+00:00Arthur Hanson Rasmussonarthur@vgpu.io2026-11-13T01:01:04+00:00urn:sha1:725898e44666b4def396f7f3c5e50712fd37aa33
The uncommitted keep-alive change wrote 0xFFFF into slot 0's status field
(u16 at notifier+0x0e) on the X DDX / GLX kick-idle channel families. Ground
truth (570.144 reference sources + stock nvidia_drv.so disassembly): slot 0
of an nvPush notifier block is the ERROR notifier; nvPushCheckChannelError
reads that status and 0xFFFF aborts every nvPushWaitForNotifier/idle wait as
a channel error. There is no pb_kickIfIdle in 570.144 - the DDX DMA-idle
test reads the progress-tracker semaphore word, not this slot. Leave slot 0
untouched; keep the 0x8000->0 completion ack for the remaining slots and the
r864 0xFFFF/0x8000 completion on the RC-watchdog/beef families. Correct the
CONT.408/409 comments accordingly.
New host/guest tooling: gpa.py (QMP gva2gpa), tick_gen.py (guest-RM timer
BO tick), guest_mode.sh (shared nvClip modeNum reader), gl_verify.sh
(X/GLX bring-up with ScreenInit-lottery retries), push_gl_tools.sh, the
gzdoom_pbuf_run.sh guest recipe and the test_tri SDL2 harness validation
program; ignore tools/guest-diag/build/.
