From 725898e44666b4def396f7f3c5e50712fd37aa33 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Thu, 12 Nov 2026 20:01:04 -0500 Subject: vgsp: stop fabricating 0xFFFF into the nvPush error notifier; add r1780 GL ops tooling 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/. --- .gitignore | 3 +++ 1 file changed, 3 insertions(+) (limited to '.gitignore') diff --git a/.gitignore b/.gitignore index f844d85..9600b79 100644 --- a/.gitignore +++ b/.gitignore @@ -170,3 +170,6 @@ kernel/golden-mme-tu104.h # generated per-cycle launcher + run scratch (r1780 cycle tooling) tools/guest-diag/launch_qemu_r1780.run.sh tools/guest-diag/run/ + +# local build outputs of the guest-diag GL tooling +tools/guest-diag/build/ -- cgit v1.2.3
